- BACKGROUND: Acute occlusion of renal bridging stent grafts after fenestrated/branched endovascular aortic repair (F/B-EVAR) is an acknowledged complication with high morbidity that often results in chronic dialysis dependence. The feasibility and effect of timely or late (≥6 hours of ischemia) renal artery revascularization has not been adequately reported.METHODS: We performed a retrospective, multicenter study across 11 tertiary institutions of all consecutive patients who had undergone revascularization of renal artery stent graft occlusions after complex EVAR. The end points were technical success, association between ischemia time and renal function salvage, interventional complications, mortality, and mid-term outcomes.RESULTS: From 2009 to 2019, 38 patients with 46 target vessels (TVs; eight bilateral occlusions) were treated for renal artery occlusions after complex EVAR (mean age, 63.5 ± 10 years; 63.2% male). Six patients had a solitary kidney (15.8%). Of the 38 patients, 16 (42.1%) had undergone FEVAR and 22 (57.9%) had undergone BEVAR. The technical success rate was 95.7% (44 of 46 TVs). The recanalization technique used was sole aspiration thrombectomy in 5.3%, aspiration thrombectomy and stent graft relining in 52.6%, and sole stent graft relining in 36.8%. The median renal ischemia time was 27.5 hours (range, 4-720 hours; interquartile range, 4-36 hours). Most patients (94.4%) had been treated after ≥6 hours of renal ischemia time, and 55.6% had been treated after 24 hours. In 14 patients (36.8%), renal function had improved after intervention (mean glomerular filtration rate improvement, 14.2 ± 9 mL/min/1.73 m2). However, 24 patients (63.2%) showed no improvement. Improvement of renal function did not correlate with the length of renal ischemia time. Of the 14 patients with bilateral renal artery occlusion or a solitary kidney, 9 experienced partial recovery of renal function and no longer required hemodialysis. In-hospital mortality was 2.6%. The cause of renal stent graft occlusion could not be identified in 50% of the TVs (23 of 46). However, in 19 (41.3%), significant stenosis or a kink of the renal stent graft was found. The median follow-up was 11 months (interquartile range, 0-28 months). The estimated 1-year patient survival and patency rate of the renal stent grafts was 97.4% and 83.8%, respectively.CONCLUSIONS: Revascularization of occluded renal bridging stent grafts after F/B-EVAR is a safe and feasible technique and can lead to significant improvement of renal function, even after long ischemia times (>24 hours) of the renal parenchyma or bilateral occlusion, as long as residual perfusion of the renal parenchyma has been preserved. Also, the long-term patency rates justify aggressive management of renal artery occlusion after F/B-EVAR.

- Background: Population estimates underpin demographic and epidemiological research and are used to track progress on numerous international indicators of health and development. To date, internationally available estimates of population and fertility, although useful, have not been produced with transparent and replicable methods and do not use standardised estimates of mortality. We present single-calendar year and single-year of age estimates of fertility and population by sex with standardised and replicable methods. Methods: We estimated population in 195 locations by single year of age and single calendar year from 1950 to 2017 with standardised and replicable methods. We based the estimates on the demographic balancing equation, with inputs of fertility, mortality, population, and migration data. Fertility data came from 7817 location-years of vital registration data, 429 surveys reporting complete birth histories, and 977 surveys and censuses reporting summary birth histories. We estimated age-specific fertility rates (ASFRs; the annual number of livebirths to women of a specified age group per 1000 women in that age group) by use of spatiotemporal Gaussian process regression and used the ASFRs to estimate total fertility rates (TFRs; the average number of children a woman would bear if she survived through the end of the reproductive age span [age 10–54 years] and experienced at each age a particular set of ASFRs observed in the year of interest). Because of sparse data, fertility at ages 10–14 years and 50–54 years was estimated from data on fertility in women aged 15–19 years and 45–49 years, through use of linear regression. Age-specific mortality data came from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 estimates. Data on population came from 1257 censuses and 761 population registry location-years and were adjusted for underenumeration and age misreporting with standard demographic methods. Migration was estimated with the GBD Bayesian demographic balancing model, after incorporating information about refugee migration into the model prior. Final population estimates used the cohort-component method of population projection, with inputs of fertility, mortality, and migration data. Population uncertainty was estimated by use of out-of-sample predictive validity testing. With these data, we estimated the trends in population by age and sex and in fertility by age between 1950 and 2017 in 195 countries and territories. Findings: From 1950 to 2017, TFRs decreased by 49·4% (95% uncertainty interval [UI] 46·4–52·0). The TFR decreased from 4·7 livebirths (4·5–4·9) to 2·4 livebirths (2·2–2·5), and the ASFR of mothers aged 10–19 years decreased from 37 livebirths (34–40) to 22 livebirths (19–24) per 1000 women. Despite reductions in the TFR, the global population has been increasing by an average of 83·8 million people per year since 1985. The global population increased by 197·2% (193·3–200·8) since 1950, from 2·6 billion (2·5–2·6) to 7·6 billion (7·4–7·9) people in 2017; much of this increase was in the proportion of the global population in south Asia and sub-Saharan Africa. The global annual rate of population growth increased between 1950 and 1964, when it peaked at 2·0%; this rate then remained nearly constant until 1970 and then decreased to 1·1% in 2017. Population growth rates in the southeast Asia, east Asia, and Oceania GBD super-region decreased from 2·5% in 1963 to 0·7% in 2017, whereas in sub-Saharan Africa, population growth rates were almost at the highest reported levels ever in 2017, when they were at 2·7%. The global average age increased from 26·6 years in 1950 to 32·1 years in 2017, and the proportion of the population that is of working age (age 15–64 years) increased from 59·9% to 65·3%. At the national level, the TFR decreased in all countries and territories between 1950 and 2017; in 2017, TFRs ranged from a low of 1·0 livebirths (95% UI 0·9–1·2) in Cyprus to a high of 7·1 livebirths (6·8–7·4) in Niger. The TFR under age 25 years (TFU25; number of livebirths expected by age 25 years for a hypothetical woman who survived the age group and was exposed to current ASFRs) in 2017 ranged from 0·08 livebirths (0·07–0·09) in South Korea to 2·4 livebirths (2·2–2·6) in Niger, and the TFR over age 30 years (TFO30; number of livebirths expected for a hypothetical woman ageing from 30 to 54 years who survived the age group and was exposed to current ASFRs) ranged from a low of 0·3 livebirths (0·3–0·4) in Puerto Rico to a high of 3·1 livebirths (3·0–3·2) in Niger. TFO30 was higher than TFU25 in 145 countries and territories in 2017. 33 countries had a negative population growth rate from 2010 to 2017, most of which were located in central, eastern, and western Europe, whereas population growth rates of more than 2·0% were seen in 33 of 46 countries in sub-Saharan Africa. In 2017, less than 65% of the national population was of working age in 12 of 34 high-income countries, and less than 50% of the national population was of working age in Mali, Chad, and Niger. Interpretation: Population trends create demographic dividends and headwinds (ie, economic benefits and detriments) that affect national economies and determine national planning needs. Although TFRs are decreasing, the global population continues to grow as mortality declines, with diverse patterns at the national level and across age groups. To our knowledge, this is the first study to provide transparent and replicable estimates of population and fertility, which can be used to inform decision making and to monitor progress.

Tidskriftsartikel (refereegranskat)abstract
- Objective: This study aimed to report the initial experience with a novel bidirectional double cuff inner branch design for incorporation of renal and mesenteric arteries in patients undergoing fenestrated and branched endovascular aortic repair (F/BEVAR). Methods: A retrospective review was undertaken of the experience of F/BEVAR with grafts integrating at least one bidirectional double cuffed inner branch implanted at three tertiary aortic centres between March 2022 and June 2023. All consecutive patients were included. Baseline characteristics, operative data, and follow up data were collected. Results were presented as number or median (interquartile range) unless otherwise stated. Results: Thirteen patients (10 male; median age 72 [68, 77] years) had F/BEVAR using a total of 15 bidirectional double cuffed inner branches (30 cuffs). Indications for bidirectional doubled cuffed inner branches included cranial vessel orientation or double renal arteries in four patients each, common coeliomesenteric trunk in three patients, and early renal artery bifurcation, renal artery origin from a false lumen requiring a flexible route for catheterisation, and surplus configuration in one patient each. Twenty three of the 30 cuffs were used, whereas the remaining seven cuffs were intentionally occluded with vascular plugs. Target vessel incorporation was successful in all bidirectional branches. There was one technical failure related to unsuccessful catheterisation of a left renal artery targeted through a unidirectional caudal inner branch. During a median follow up of seven months there were no instances of target vessel instability or re-interventions and two patients died of causes unrelated to the bidirectional branches. Conclusion: The results of the use of bidirectional double cuff inner branches are promising, with high technical success and no short term branch related complications in this preliminary experience. This could potentially expand the applicability of branch endografting of complex endovascular aortic repairs, but long term results are still missing.

- Objective: After alerts on Endovascular Aneurysm Seal (EVAS) failure were raised, the European Society for Vascular Surgery (ESVS) Abdominal Aortic Aneurysm (AAA) Clinical Practice Guidelines Writing Committee (WC) initiated a task force with the aim to provide guidance on surveillance and management of patients with implanted EVAS devices.Methods: Based on a scoping review of risk for late serious aortic-related adverse events in patients treated with EVAS for AAA, the ESVS AAA Guidelines WC agreed on recommendations graded according to the European Society of Cardiology (ESC) grading system.Results: EVAS has a very high incidence of late endograft migration resulting in proximal type 1 endoleak with risk of rupture, requiring open conversion with device explantation. The reported mortality rate for elective explantation varies between 0% and 14%, while acute conversion for rupture has a very dismal prognosis with a 67 – 75% mortality rate.Conclusion: It is recommended that all patients in whom a Nellix device has been implanted should be identified, properly informed, and enrolled in enhanced surveillance. If device failure is detected, early elective device explantation should be considered in surgically fit patients.

- Objective:To report the mid-term outcomes of fenestrated-branched endovascular aneurysm repair (F-BEVAR) following a failed previous endovascular aneurysm repair (pEVAR) or previous open aneurysm repair (pOAR).Methods:Data from consecutive patients who underwent F-BEVAR for pEVAR or pOAR from 2006 to 2021 from 17 European vascular centers were analyzed. Endpoints included technical success, major adverse events, 30-day mortality, and 5-year estimates of survival, target vessel primary patency, freedom from reinterventions, type I/III endoleaks, and sac growth >5 mm.Background:Treatment of a failed previous abdominal aortic aneurysm repair is a complex undertaking. F-BEVAR is becoming an increasingly attractive option, although comparative data are limited regarding associated risk factors, indications for treatment, and various outcomes.Results:There were 526 patients included, 268 pOAR and 258 pEVAR. The median time from previous repair to F-BEVAR was 7 (interquartile range, 4-12) years, 5 (3-8) for pEVAR, and 10 (6-14) for pOAR, P<0.001. Predominant indication for treatment was type Ia endoleak for pEVAR and progression of the disease for pOAR. Technical success was 92.8%, pOAR (92.2%), and pEVAR (93.4%), P=0.58. The 30-day mortality was 6.5% overall, 6.7% for pOAR, and 6.2% for pEVAR, P=0.81. There were 1853 treated target vessels with 5-year estimates of primary patency of 94.4%, pEVAR (95.2%), and pOAR (94.4%), P=0.03. Five-year estimates for freedom from type I/III endoleaks were similar between groups; freedom from reintervention was lower for pEVAR (38.3%) than for pOAR (56.0%), P=0.004. The most common indication for reinterventions was for type I/III endoleaks (37.5%).Conclusions:Repair of a failed pEVAR or pOARis safe and feasible with comparable technical success and survival rates. While successful treatment can be achieved, significant rates of reintervention should be anticipated, particularly for issues related to instability of target vessels/bridging stents.

- Objective: To describe outcomes after elective and non-elective fenestrated-branched endovascular aortic repair (FB-EVAR) for thoracoabdominal aortic aneurysms (TAAAs).Background: FB-EVAR has been increasingly utilized to treat TAAAs; however, outcomes after non-elective versus elective repair are not well described.Methods: Clinical data of consecutive patients undergoing FB-EVAR for TAAAs at 24 centers (2006-2021) were reviewed. Endpoints including early mortality and major adverse events (MAEs), all-cause mortality, and aortic-related mortality (ARM), were analyzed and compared in patients who had non-elective versus elective repair.Results: A total of 2603 patients (69% males; mean age 72 +/- 10 year old) underwent FB-EVAR for TAAAs. Elective repair was performed in 2187 patients (84%) and non-elective repair in 416 patients [16%; 268 (64%) symptomatic, 148 (36%) ruptured]. Non-elective FB-EVAR was associated with higher early mortality (17% vs 5%, P < 0.001) and rates of MAEs (34% vs 20%, P < 0.001). Median follow-up was 15 months ( interquartile range, 7-37 months). Survival and cumulative incidence of ARM at 3 years were both lower for non-elective versus elective patients (50 +/- 4% vs 70 +/- 1% and 21 +/- 3% vs 7 +/- 1%, P < 0.001). On multivariable analysis, non-elective repair was associated with increased risk of all-cause mortality ( hazard ratio, 1.92; 95% CI] 1.50-2.44; P < 0.001) and ARM (hazard ratio, 2.43; 95% CI, 1.63-3.62; P < 0.001).Conclusions: Non-elective FB-EVAR of symptomatic or ruptured TAAAs is feasible, but carries higher incidence of early MAEs and increased all-cause mortality and ARM than elective repair. Long-term follow-up is warranted to justify the treatment.

Tidskriftsartikel (refereegranskat)abstract
- Objective: The aim of this study was to compare outcomes of single or multistage approach during fenestrated-branched endovascular aortic repair (FB-EVAR) of extensive thoracoabdominal aortic aneurysms (TAAAs).Methods: We reviewed the clinical data of consecutive patients treated by FB-EVAR for extent I to III TAAAs in 24 centers (2006-2021). All patients received a single brand manufactured patient-specific or off-the-shelf fenestrated-branched stent grafts. Staging strategies included proximal thoracic aortic repair, minimally invasive segmental artery coil embolization, temporary aneurysm sac perfusion and combinations of these techniques. Endpoints were analyzed for elective repair in patients who had a single-or multistage approach before and after propensity score adjustment for baseline differences, including the composite 30-day/in-hospital mortality and/or permanent paraplegia, major adverse event, patient survival, and freedom from aortic-related mortality.Results: A total of 1947 patients (65% male; mean age, 71 +/- 8 years) underwent FB-EVAR of 155 extent I (10%), 729 extent II (46%), and 713 extent III TAAAs (44%). A single-stage approach was used in 939 patients (48%) and a multistage approach in 1008 patients (52%). A multistage approach was more frequently used in patients undergoing elective compared with non-elective repair (55% vs 35%; P < .001). Staging strategies were proximal thoracic aortic repair in 743 patients (74%), temporary aneurysm sac perfusion in 128 (13%), minimally invasive segmental artery coil embolization in 10 (1%), and combinations in 127 (12%). Among patients undergoing elective repair (n = 1597), the composite endpoint of 30-day/in-hospital mortality and/or permanent paraplegia rate occurred in 14% of single-stage and 6% of multistage approach patients (P < .001). After adjustment with a propensity score, multistage approach was associated with lower rates of 30-day/in-hospital mortality and/or permanent paraplegia (odds ratio, 0.466; 95% confidence interval, 0.271-0.801; P = .006) and higher patient survival at 1 year (86.9 +/- 1.3% vs 79.6 +/- 1.7%) and 3 years (72.7 +/- 2.1% vs 64.2 +/- 2.3%; adjusted hazard ratio, 0.714; 95% confidence interval, 0.528-0.966; P = .029), compared with a single stage approach.Conclusions: Staging elective FB-EVAR of extent I to III TAAAs was associated with decreased risk of mortality and/or permanent paraplegia at 30 days or within hospital stay, and with higher patient survival at 1 and 3 years.

- Objective: The aim of this multicentric registry was to assess the outcomes of "anteRior versus posteRior divisional bRanches Of the hYpogastric artery as distAl landing zone for iLiac branch devices (R3OYAL)."Methods: The main exposure of interest for the purpose of this study was the internal iliac artery (IIA) divisional branch (anterior vs posterior) that was used as distal landing zone. Early endpoints included technical success and adverse events. Late endpoints included survival, primary/secondary IIA patency, and IIA branch instability.Results: A total of 171 patients were included in the study, of which 50 received bilateral implantation of iliac branch devices (IBDs). This resulted in a total of 221 incorporated IIAs included in the final analysis, of which 40 were anterior divisional branches and 181 were posterior divisional branches. Technical success was high in both groups (anterior division: 98% vs posterior division: 100%, P = .18). Occurrence of any adverse event was noted in 14% of patients in both groups (P = 1.0). The overall rate of freedom from the composite IBD branch instability did not show significant differences between patients receiving distal landing in the anterior or posterior division of the IIA at 3 years (79% vs 87%, log-rank test = .215). The 3-year estimates of IBD patency were significantly lower in patients who received distal landing in the anterior divisional branch than those who received distal landing in the posterior divisional branch (primary patency: 81% vs 96%, log-rank test = .009; secondary patency: 81% vs 97%, log-rank test < .001).Conclusions: The use of the anterior or posterior divisional branches of the IIA as distal landing zone for IBD implantation shows comparable profiles in terms of immediate technical success, perioperative safety, and side-branch instability up to 3 years. However, IBD patency at 3 years was higher when the distal landing zone was achieved within the posterior divisional branch of the IIA.Clinical Impact: The results from this large multicentric registry confirm that use of the anterior or posterior divisional branches of the internal iliac artery (IIA) as distal landing zone for implantation of iliac branch devices (IBD) shows comparable profiles of safety and feasibility, thereby allowing to extend the indications for endovascular repair of aorto-iliac aneurysms to cases with unsuitable anatomy within the IIA main trunk. Although mid-term rates of device durability and branch instability seem to be similar, the rates of primary and secondary IBD patency at three years was favored when the distal landing zone was achieved in the posterior divisional branch of the IIA.

- The lifetime risk of stroke has been calculated in a limited number of selected populations. We sought to estimate the lifetime risk of stroke at the regional, country, and global level using data from a comprehensive study of the prevalence of major diseases.We used the Global Burden of Disease (GBD) Study 2016 estimates of stroke incidence and the competing risks of death from any cause other than stroke to calculate the cumulative lifetime risks of first stroke, ischemic stroke, or hemorrhagic stroke among adults 25 years of age or older. Estimates of the lifetime risks in the years 1990 and 2016 were compared. Countries were categorized into quintiles of the sociodemographic index (SDI) used in the GBD Study, and the risks were compared across quintiles. Comparisons were made with the use of point estimates and uncertainty intervals representing the 2.5th and 97.5th percentiles around the estimate.The estimated global lifetime risk of stroke from the age of 25 years onward was 24.9% (95% uncertainty interval, 23.5 to 26.2); the risk among men was 24.7% (95% uncertainty interval, 23.3 to 26.0), and the risk among women was 25.1% (95% uncertainty interval, 23.7 to 26.5). The risk of ischemic stroke was 18.3%, and the risk of hemorrhagic stroke was 8.2%. In high-SDI, high-middle-SDI, and low-SDI countries, the estimated lifetime risk of stroke was 23.5%, 31.1% (highest risk), and 13.2% (lowest risk), respectively; the 95% uncertainty intervals did not overlap between these categories. The highest estimated lifetime risks of stroke according to GBD region were in East Asia (38.8%), Central Europe (31.7%), and Eastern Europe (31.6%), and the lowest risk was in eastern sub-Saharan Africa (11.8%). The mean global lifetime risk of stroke increased from 22.8% in 1990 to 24.9% in 2016, a relative increase of 8.9% (95% uncertainty interval, 6.2 to 11.5); the competing risk of death from any cause other than stroke was considered in this calculation.In 2016, the global lifetime risk of stroke from the age of 25 years onward was approximately 25% among both men and women. There was geographic variation in the lifetime risk of stroke, with the highest risks in East Asia, Central Europe, and Eastern Europe. (Funded by the Bill and Melinda Gates Foundation.).

Forskningsöversikt (refereegranskat)abstract
- Objective: To perform a systematic review and meta-analysis of the outcomes of physician modified endografts (PMEG) for the treatment of thoraco-abdominal (TAAA) and complex abdominal aortic aneurysms (C-AAA).Data Sources: MEDLINE, CENTRAL, Web of Science Core Collection, Scielo, and Open Grey.Review Methods: The databases were searched from inception to July 2021 for studies reporting on outcomes of PMEGs for TAAA or C-AAA repair. A systematic review was conducted (protocol CRD42021267856) and data were pooled using a random effects model of proportions. The outcomes analysed were major adverse events at 30 days (30 day mortality, myocardial infarction, respiratory failure requiring prolonged ventilation [> 24 hours or re-intubation], renal failure requiring dialysis, bowel ischaemia requiring surgery, major stroke, or definitive paraplegia); technical success; 30 day mortality; ruptures; spinal cord ischaemia; endoleaks; re-interventions; and target vessel patency.Results: Twenty studies were included. Overall study quality assessment was found to be low. Overall, 909 PMEGs were reported and analysed. Regarding aneurysm location (n = 867), 222 patients had extent I - III TAAAs and 645 had C-AAA or extent IV TAAA. Regarding presentation, 14 studies reported whether the patients were treated in an elective or urgent setting (n = 782). Overall, 500 (63.9%) patients were treated in an elective setting and 282 (36.1%) in an urgent setting. Major adverse events (at 30 days) occurred in 15.5% of patients (95% confidence interval [CI] 10.8 - 20.8; I-2 = 63%, 135/832 cases): 11.6% (95% CI 8.1 - 15.7; I-2 = 0%, 23/280 cases) for elective patients and 24.6% for urgent (95% CI 14.1 - 36.6; I-2 = 65%, 50/192 cases). Overall technical success was 97.2% (95% CI 95.4 - 98.7; I-2 = 0%, 587/611 cases): 98.0% (95% CI 92.1 - 100; I-2 = 0%, 106/113cases) for extent I - III TAAAs and 99.4% (95% CI 97.5 - 100; I-2 = 0%, 317/324 cases) for C-AAA and extent IV TAAAs. Regarding technique, technical success was 96.1% for fenestrated endovascular repair (FEVAR; 95% CI 93.2 - 98.4; I-2 = 0%, 313/329 cases) and 99.8% for FEVAR/branched endovascular repair (95% CI 99.8 - 100; I-2 = 0%, 17/18 cases).Conclusion: Physician modified fenestrated or branched grafts for endovascular aortic repair seem feasible and safe in the short term. However, the quality of the available data is low, which highlights the need for better and more accurate data regarding this technique.

- Background: Alcohol use is a leading risk factor for death and disability, but its overall association with health remains complex given the possible protective effects of moderate alcohol consumption on some conditions. With our comprehensive approach to health accounting within the Global Burden of Diseases, Injuries, and Risk Factors Study 2016, we generated improved estimates of alcohol use and alcohol-attributable deaths and disability-adjusted life-years (DALYs) for 195 locations from 1990 to 2016, for both sexes and for 5-year age groups between the ages of 15 years and 95 years and older.Methods: Using 694 data sources of individual and population-level alcohol consumption, along with 592 prospective and retrospective studies on the risk of alcohol use, we produced estimates of the prevalence of current drinking, abstention, the distribution of alcohol consumption among current drinkers in standard drinks daily (defined as 10 g of pure ethyl alcohol), and alcohol-attributable deaths and DALYs. We made several methodological improvements compared with previous estimates: first, we adjusted alcohol sales estimates to take into account tourist and unrecorded consumption; second, we did a new meta-analysis of relative risks for 23 health outcomes associated with alcohol use; and third, we developed a new method to quantify the level of alcohol consumption that minimises the overall risk to individual health.Findings: Globally, alcohol use was the seventh leading risk factor for both deaths and DALYs in 2016, accounting for 2.2% (95% uncertainty interval [UI] 1.5-3.0) of age-standardised female deaths and 6.8% (5.8-8.0) of age-standardised male deaths. Among the population aged 15-49 years, alcohol use was the leading risk factor globally in 2016, with 3.8% (95% UI 3.2-4-3) of female deaths and 12.2% (10.8-13-6) of male deaths attributable to alcohol use. For the population aged 15-49 years, female attributable DALYs were 2.3% (95% UI 2.0-2.6) and male attributable DALYs were 8.9% (7.8-9.9). The three leading causes of attributable deaths in this age group were tuberculosis (1.4% [95% UI 1. 0-1. 7] of total deaths), road injuries (1.2% [0.7-1.9]), and self-harm (1.1% [0.6-1.5]). For populations aged 50 years and older, cancers accounted for a large proportion of total alcohol-attributable deaths in 2016, constituting 27.1% (95% UI 21.2-33.3) of total alcohol-attributable female deaths and 18.9% (15.3-22.6) of male deaths. The level of alcohol consumption that minimised harm across health outcomes was zero (95% UI 0.0-0.8) standard drinks per week.Interpretation: Alcohol use is a leading risk factor for global disease burden and causes substantial health loss. We found that the risk of all-cause mortality, and of cancers specifically, rises with increasing levels of consumption, and the level of consumption that minimises health loss is zero. These results suggest that alcohol control policies might need to be revised worldwide, refocusing on efforts to lower overall population-level consumption.

- Purpose: To evaluate the outcomes of preserving the internal iliac artery (IIA) with iliac branched devices (IBDs) during acute endovascular repair of ruptured aortoiliac aneurysms. Material and Methods: This is a multicenter retrospective review of all consecutive patients undergoing acute endovascular repair of ruptured aortoiliac aneurysm with an IBD at 8 aortic centers between December 2012 and June 2020. A control group was used where the IIA was intentionally occluded from the same study period. The main outcome measures were 30-day mortality, major adverse events, technical success, and clinical success. Secondary outcomes were buttock claudication, primary patency, primary-assisted and secondary patency of the IBD, occurrence of endoleak types I/III, and reintervention. Values are presented as numbers and percentages or interquartile range in parenthesis. Results: Forty-eight patients were included in the study: 24 with IBD and 24 with IIA occlusion. There was no difference in demographics, cardiovascular risk factors, and aneurysm extent. Twenty (83%) of them were hemodynamically stable during the procedure as opposed to 14 (58%, p=.23) with the IIA occlusion. Technical success was achieved in all cases with a procedure time of 180 (133-254) minutes, 45 (23-65) of which were from IBD. There were 2 (8%) deaths during the first 30 days and 2 (8%) major complications unrelated to the IBD, whereas in the IIA occlusion, the figures were 10 (42%) and 7 (29%), respectively. No patient in the IBD group developed buttock claudication compared to 8 (57%, p<.0001) in the IIA occlusion group; 1 (4%) patient developed bowel ischemia on both groups, with 1 in the IIA occlusion group needing resection. The median follow-up duration was 17 months (interquartile range 2-39) for the IBD group, with a primary patency of 60 +/- 14% at 3 years that went up to 92 +/- 8% with reinterventions (8 reinterventions in 6 patients). When the first 90 days were disregarded, there were no differences in survival between the groups. Conclusion: IBD is a valid alternative for maintaining the pelvic circulation for endovascular aortic aneurysm repair of ruptured aortoiliac aneurysms. The technical success and midterm outcomes are very satisfactory but require patient selection particularly regarding hemodynamic stability. The reintervention rate is considerable, mandating continuous follow-up. Clinical Impact This multicenter study demonstrates that ruptured aortoiliac aneurysms do not necessarily require mandatory occlusion of hypogastric arteries. Iliac branch devices are shown to be a valid alternative in highly selected cases, with good midterm results, even if reinterventions are required in a significant proportion of patients.

- Purpose:To report a new facilitated method for securing target vessel access during single fenestrated and branched thoracic endovascular repair using a guidewire fixator.Technique: The Liungman Guidewire Fixator (LGF) includes a 0.035-inch guidewire that is fitted with a stopper close to the distal end and a self-expanding anchoring element that is freely movable over the guidewire to the point of the stopper. The technique of using a LGF for anchoring in a target vessel is described in a 75-year-old woman with a 53-mm saccular arch aneurysm. She was treated with a fenestrated Zenith stent-graft that had a catheter-preloaded fenestration for the left subclavian artery (LSA) and a scallop for the left common carotid artery. To avoid through-and-through wire and brachial access, the LGF was used to secure the guidewire in the LSA during stent-graft deployment.Conclusion: The use of an LGF for anchoring in the target LSA during fenestrated arch endografting was feasible and safe.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: To describe a novel modification technique to lower the distal radial force of a thoracic stent-graft so as to avert stent-graft-induced new entry tears (SINE) in the fragile aorta of patients with genetic aortic disease and aortic dissection. Technique: A commercially available thoracic stent-graft is partially deployed on a back table. The most distal Z-stent is removed, the distal fabric is marked by vascular clips, and the modified stent-graft is reloaded and deployed in the true lumen of an aortic dissection. The technique is demonstrated in 3 patients with aortic dissection related to genetic aortic diseases. Conclusion: Creating a low distal radial force stent-graft is easy and can be done in a short time. Endovascular implantation appears feasible and safe.

Tidskriftsartikel (refereegranskat)abstract
- Background: In situ fenestration of aortic stent grafts for treatment of aortic arch aneurysms is a new option for endovascular aortic arch repair. So far, only few reports have shown perioperative and short-term results of in situ fenestrations for aortic arch diseases. We present the multicenter experience with the aortic arch in situ fenestration technique documented in the AARCHIF registry for treatment of aortic arch aneurysms or localized type A aortic dissections and analyzed perioperative outcome and midterm follow-up. Methods: Patients with aortic arch pathologies treated by aortic arch in situ fenestration with proximal stent graft landing in aortic arch Ishimura zones 0 and 1 were included in the registry. Stent-graft in situ fenestrations were created using needles or radiofrequency or laser catheters and completed by implantation of covered connecting stent grafts. Single in situ fenestrations for the left subclavian artery (LSA) were excluded. Results: Between 06/2009 and 03/2017, twenty-five patients were treated by in situ stent-graft fenestrations for aortic arch pathologies at 9 institutions in 7 different countries, 3 of them as bailout procedures for stent-graft malplacement. In situ fenestrations were performed for the brachiocephalic trunk (n = 20), the left common carotid artery (n = 21) and the LSA (n = 9). Technical success for intended in situ fenestrations was 94.0% (47/50), with additional supraaortic bypass procedures performed in 14 patients. Perioperative mortality occurred in 1 (4.0%) patient, treated as a bailout procedure and 3 (12.0%) perioperative strokes were observed. One proximal aortic stent-graft nonalignment and 4 type III endoleaks, 2 early and 2 late, required reeintervention. During follow-up (1–118 months), the diameter of aortic arch aneurysms decreased from 61.5 ± 4.1 mm to 48.4 ± 3.2 mm (P = 0.02) and, so far, 6 patients died from diseases unrelated to their aortic arch pathologies with a mean survival time of 79.5 months and 3 endovascular reinterventions for distal aortic expansion were performed. Cerebrovascular event (n = 4) was the most relevant prognostic factor for mortality during midterm follow-up (P = 0.003). Conclusions: The aortic arch in situ fenestration technique for endovascular aortic arch repair seems to be valuable treatment option for selected patients, although initial consideration of other treatment options is mandatory. Data about long-term durability are required.

- Objective: To evaluate short term outcomes related to the use of the Zenith TX2 Dissection Endovascular Graft (ZDEG) and the Zenith Dissection Bare stent (ZDES) for the treatment of Stanford type B aortic dissections. Methods: This retrospective multicenter case cohort study collated data from 10 European institutions for patients with both complicated and uncomplicated type B aortic dissection treated with ZDEG and ZDES between 2011 and 2018. The primary end point was mortality at 30 and 90 days. Secondary end points included complications related to TEVAR, such as, type Ia endoleak, stroke, paraparesis, paraplegia, and retrograde type A dissection (RTAD). Statistical analysis was carried out using the t test, or one-way analysis of variance and the chi(2) or Fisher exact tests. Results: We treated 120 patients (87 male; mean age, 62.7 +/- 12.2years) either in the acute 76 (63.3%), subacute 16 (13.3%), or chronic 28 (23.3%) phase. Seven patients (5.8%) died within 30 days after the index procedure and two (1.7%) between 30 and 90 days. There was one instance of postoperative RTAD in a patient treated for rupture. Stroke and paraplegia occurred in three (2.5%) and five (4.2%), patients, respectively. Eight patients (6.7%) had a type Ia endoleak in the perioperative period. There were no instances of paraplegia, no permanent dialysis, and no requirement for adjunctive superior mesenteric or celiac artery stenting in the 33 patients (27.5%) who were treated by concurrent placement of ZDES distal to the ZDEG. The length and distal oversizing of ZDEG components used was less in this group. Conclusions: The present series demonstrates a low (<1%) RTAD rate and favorable morbidity and mortality. The lower rate of paraplegia, dialysis, and visceral artery stenting in the cohort that had adjunctive use of ZDES is compelling and merits further assessment.

- BackgroundThe increasing proportion of elderly patients being treated for abdominal aortic aneurysm (AAA) in the endovascular era is controversial.ObjectivesThis study compared 30-day outcomes of endovascular aortic repair (EVAR) in nonagenarians (NAs) with non-nonagenarians (NNAs).MethodsThis retrospective analysis of the American College of Surgeons National Surgical Quality Improvement Program database included EVAR procedures performed from 2011 to 2017. Multivariate logistic regression in the unadjusted cohort, followed by propensity-score matching (PSM), was performed. Primary outcomes were 30-day mortality and 30-day major adverse events.ResultsA total of 12,267 patients were included (365 NAs). Ruptured aneurysms accounted for 6.7% (n = 819): 15.7% (n = 57) in NAs versus 6.5% (n = 762) in NNAs (p < 0.001). Mean aneurysm diameter was 6.5 ± 1.8 cm in NAs versus 5.8 ± 1.7 cm in NNAs (p < 0.001). The unadjusted 30-day mortality was 9.9% in NA versus 2.2% in NNAs (p < 0.001). Multivariate analysis revealed age ≥90 years (odds ratio [OR]: 3.36), male sex (OR: 1.78), functional status (OR: 4.22), pre-operative ventilator dependency (OR: 3.80), bleeding disorders (OR: 1.52), dialysis (OR: 2.56), and ruptured aneurysms (OR: 17.21) as independent predictors of mortality. After PSM, no differences in 30-day mortality (intact AAA [iAAA]: 5.3% NA vs. 3% NNA [p = 0.15]; ruptured AAA [rAAA]: 38% NA vs. 28.6% NNA [p = 0.32]) or 30-day major adverse events (iAAA: 7% NA vs. 4.6% NNA [p = 0.22]; rAAA: 28% NA vs. 36.7% NNA [p = 0.35]) were observed.ConclusionsAge was identified as an independent predictor of 30-day mortality after EVAR on multivariate analysis. However, no differences were found after PSM, suggesting that being ≥90 years of age but with similar comorbidities to younger patients is not associated with a higher short-term mortality after EVAR. Age ≥90 years alone should not exclude patients from EVAR, and tailored indications and carefully balanced risk assessment are advised.

"In vitro" evaluation of the optimal degree of oversizing of thoracic endografts in prosthetic landing areas : A Pilot Study
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Objectives: The optimal degree of proximal thoracic endograft oversizing when aiming for durable sealing in prosthetic grafts in unknown. The aim of this study was to create an in vitro model for testing different oversized thoracic endografts in a reproducible and standardized manner, and subsequently determining the optimal oversizing range when planning procedures with proximal landing in prosthetic zones in the descending thoracic aorta or aortic arch.Materials and Methods: An in-vitro model consisting of a fixated 24mm polyethylene terephthalate (Dacron) graft sutured proximally and distally to two specifically designed 40mm rings, with four force sensing resistors attached at 4 equally distant positions and a USB camera attached proximally for photographic and video documentation was used for deployment of Zenith TX2 (Cook Medical, Bloomington, IN, USA) dissection platform endografts with diameters between 24 and 36mm. After deployment, ballooning with a 32mm compliant balloon was performed to simulate real life conditions. Assessment of oversizing included visual inspection, calculation of the valley areas created between the prosthetic wall and the stentgraft fabric, distance between stentgraft peaks, radial force exerted by the proximal sealing stent and the pull-out force necessary for endograft extraction.Results: A total of 70 endografts were deployed: 10x 24mm, 10x 26mm, 10x 28mm, 10x30mm, 10x32mm, 10x34mm and 10x36mm, with oversizing ranging between 0-50%. Two cases of infolding occurred with 50% oversizing. Valley areas increased from 8.79 ± 0,23 mm with 16.7% oversizing to 14.26 ± 0.45 mmÇ for 50% oversizing (p<.001). There was a significant difference in the pull-out force required for endografts <10% oversizing vs. 10% oversizing or more (p<.001), which reached a plateau at approximately 4 N after oversizing > 15%. The mean radial force of the proximal sealing stent was greater after remodelling with a compliant balloon (.55 ± .02 N vs .60 ± .02 N after ballooning (p<.001)). However, larger oversizing did not lead to an increase in the radial force exerted by the proximal sealing stent.Conclusion: The findings of this study offer additional insight into the mechanics of oversized stentgrafts in surgical grafts. In endografts with the z-stent design (TX2), oversizing below 16.7% resulted in reduced resistance to displacement forces, while oversizing > 50% was associated to major infolding in 20% of the cases. Long-term in vitro and in vivo testing are required to understand how these mechanical properties impact clinical outcomes of oversizing.

International Collaborative Study Reporting Outcomes on Fenestrated Endovascular Aortic Repair in OCtogenarian Patients : The FEVOC study
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Objective: With an increasing life expectancy, more octogenarian patients are referred with complex aortic aneurysms (cAAA). The aim of this study was to evaluate short and mid-term outcomes following fenestrated aortic repair (FEVAR) in octogenarians.Methods: Retrospective, multicentre cohort study including 8 centres across Europe and New Zealand. Consecutive patients undergoing elective FEVAR for the treatment of juxta/pararenal or type IV thoracoabdominal aortic aneurysms between 2013 and 2021 were included. The primary outcome was 30-day mortality. Secondary outcomes included 1, 2 and 5-year survival rates and mid-to-long term reintervention rates.Results: A total of 729 patients were included, of which 169 were octogenarians. Octogenarian patients were more frequently male and had larger (61mm vs. 58mm) aneurysms. No differences in 30-day mortality (4.7% vs. 3.9%) or 30-day complication rates (29% vs 28.4%) were found. Median follow-up was 23.56 months. The 1, 2 and 5-year survival rates for octogenarian vs nonoctogenarian patients were 90.7%, 80.1% and 40.1% vs. 90.2%, 85.5% and 68.1%, respectively (p=.001). Cox regression analysis found a BMI ≥ 30 (HR 0.50, 95% CI 0.28-0.88), chronic heart failure (HR 2.14, 95% CI 1.04 – 4.39) and AAA diameter between 60-70mm (HR 2.35, 95% CI 1.31 – 4.23) to be predictors of longterm mortality.Conclusions: Thirty-day outcomes after FEVAR were similar in octogenarians and younger patients. However, mid to long term survival rates, especially after 3 years, are considerably low in both groups. Whilst FEVAR in octogenarians can be performed safely and with good early outcomes, methods to improve case selection and ensure patient benefit in the long term are highly of interest.

Forskningsöversikt (refereegranskat)abstract
- Objective: To evaluate the contemporary growth rate of small abdominal aortic aneurysms (AAAs) in view of recent epidemiological changes, such as decreasing smoking rates and establishment of population screening programmes.Data sources: MEDLINE, CENTRAL, PsycINFO, Web of Science Core Collection, and OpenGrey databases.Review methods: Systematic review following the PRISMA guidelines. In October 2021, databases were queried for studies reporting on AAA growth rates published from 2015 onwards. The primary outcome was contemporary AAA growth rates in mm/year. Data were pooled in a random effects model meta-analysis, and heterogeneity was assessed through the I2 statistic. GRADE assessment of the findings was performed. The protocol was published in PROSPERO (CRD42022297404).Results: Of 8 717 titles identified, 43 studies and 28 277 patients were included:1 241 patients from randomised controlled trials (RCTs), 23 941 from clinical observational studies, and 3 095 from radiological or translational research studies. The mean AAA growth rate was 2.38 mm/year (95% CI 2.16 – 2.60 mm/year; GRADE = low), with meta-regression analysis adjusted for baseline diameter showing an increase of 0.08 mm/year (95% CI 0.024 – 0.137 mm/year; p = .005) for each millimetre of increased baseline diameter. When analysed by study type, the growth rate estimated from RCTs was 1.88 mm/year (95% CI 1.69 – 2.06 mm/year; GRADE = high), while it was 2.31 mm/year (95% CI 1.95 – 2.67 mm/year; GRADE = moderate) from clinical observational studies, and 2.85 mm/year (95% CI 2.44 – 3.26 mm/year; GRADE = low) from translational and radiology based studies (p < .001). Heterogeneity was high, and small study publication bias was present (p = .003), with 27 studies presenting a moderate to high risk of bias. The estimated growth rate from low risk studies was 2.09 mm/year (95% CI 1.87 – 2.32; GRADE = high).Conclusion: This study estimated a contemporaneous AAA growth rate of 2.38 mm/year, being unable to demonstrate any clinically meaningful AAA growth rate reduction concomitant with changed AAA epidemiology. This suggests that the RESCAN recommendations on small AAA surveillance are still valid. However, sub-analysis results from RCTs and high quality study data indicate potential lower AAA growth rates of 1.88 – 2.09 mm/year, findings that should be validated in a high quality prospective registry.

- Background The scale-up of tobacco control, especially after the adoption of the Framework Convention for Tobacco Control, is a major public health success story. Nonetheless, smoking remains a leading risk for early death and disability worldwide, and therefore continues to require sustained political commitment. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) offers a robust platform through which global, regional, and national progress toward achieving smoking-related targets can be assessed. Methods We synthesised 2818 data sources with spatiotemporal Gaussian process regression and produced estimates of daily smoking prevalence by sex, age group, and year for 195 countries and territories from 1990 to 2015. We analysed 38 risk-outcome pairs to generate estimates of smoking-attributable mortality and disease burden, as measured by disability-adjusted life-years (DALYs). We then performed a cohort analysis of smoking prevalence by birth-year cohort to better understand temporal age patterns in smoking. We also did a decomposition analysis, in which we parsed out changes in all-cause smoking-attributable DALYs due to changes in population growth, population ageing, smoking prevalence, and risk-deleted DALY rates. Finally, we explored results by level of development using the Socio-demographic Index (SDI). Findings Worldwide, the age-standardised prevalence of daily smoking was 25.0% (95% uncertainty interval [UI] 24.2-25.7) for men and 5.4% (5.1-5.7) for women, representing 28.4% (25.8-31.1) and 34.4% (29.4-38.6) reductions, respectively, since 1990. A greater percentage of countries and territories achieved significant annualised rates of decline in smoking prevalence from 1990 to 2005 than in between 2005 and 2015; however, only four countries had significant annualised increases in smoking prevalence between 2005 and 2015 (Congo [Brazzaville] and Azerbaijan for men and Kuwait and Timor-Leste for women). In 2015, 11.5% of global deaths (6.4 million [95% UI 5.7-7.0 million]) were attributable to smoking worldwide, of which 52.2% took place in four countries (China, India, the USA, and Russia). Smoking was ranked among the five leading risk factors by DALYs in 109 countries and territories in 2015, rising from 88 geographies in 1990. In terms of birth cohorts, male smoking prevalence followed similar age patterns across levels of SDI, whereas much more heterogeneity was found in age patterns for female smokers by level of development. While smoking prevalence and risk-deleted DALY rates mostly decreased by sex and SDI quintile, population growth, population ageing, or a combination of both, drove rises in overall smoking-attributable DALYs in low-SDI to middle-SDI geographies between 2005 and 2015. Interpretation The pace of progress in reducing smoking prevalence has been heterogeneous across geographies, development status, and sex, and as highlighted by more recent trends, maintaining past rates of decline should not be taken for granted, especially in women and in low-SDI to middle-SDI countries. Beyond the effect of the tobacco industry and societal mores, a crucial challenge facing tobacco control initiatives is that demographic forces are poised to heighten smoking's global toll, unless progress in preventing initiation and promoting cessation can be substantially accelerated. Greater success in tobacco control is possible but requires effective, comprehensive, and adequately implemented and enforced policies, which might in turn require global and national levels of political commitment beyond what has been achieved during the past 25 years.

- PURPOSE: To evaluate the outcomes of total endovascular aortic arch repair using three-vessel inner branch stent-grafts for aneurysms and chronic dissections.METHODS: We reviewed the clinical data and outcomes of consecutive patients treated by total endovascular aortic arch repair at eight academic centers using three-vessel inner branch stent-grafts (William Cook Europe, Bjaeverskov, Denmark) between 2016 to 2019. All patients received three vessel designs with two antegrade and one retrograde inner branch, which was used to incorporate the innominate (IA), left common carotid (LCCA) and left subclavian arteries (LSA). The antegrade inner branches were accessed via carotid or upper extremity access. A preloaded catheter was used for access to the retrograde LSA branch via trans-femoral approach. End-points were technical success, mortality, major adverse events (MAEs), any stroke (minor or major) or transient ischemia attack (TIA), secondary interventions, target vessel patency, target vessel instability, aneurysm-related mortality and patient survival.RESULTS: There were 39 patients (31 male patients [79%], mean age 70±7) treated for 14 (36%) degenerative and 25 (64%) chronic post-dissection arch aneurysms. Clinical characteristics included American Society of Anesthesiologist (ASA) classification > 3 in 28 patients (95%) and prior median sternotomy for ascending aortic repair in 28 patients (72%). Technical success rate was 100%. There were two in-hospital or 30-day deaths (5%) and two strokes (one minor). Combined mortality/any stroke rate was 8% (n=3). MAEs occurred in 10 patients (26%), including respiratory failure in four patients (10%) and estimated blood loss >1L, myocardial infarction and acute kidney injury in two patients each (5%). Median follow up was 3.2 months (IQR, 1 to 14). Twelve patients (31%) required secondary interventions to treat vascular access complications in five patients, endoleak in six patients (three type II, one type IC, one type IA/IB, one type IIIA) and target vessel stenosis in one patient. At 1-year, primary and secondary patency rates and freedom from target vessel instability were 95%±5%, 100% and 91%±5%. Freedom from aortic-related mortality and patient survival were 94%±4% and 90%±6%, respectively.CONCLUSION: This multicenter global experience demonstrates the technical feasibility and safety of total endovascular aortic arch repair for aneurysms and chronic dissections using three-vessel inner branch stent-grafts. Mortality and stroke rates compare favorably to open surgical repair in a higher risk group of patients. Rate of secondary interventions was high (31%), emphasizing need for larger experience and longer follow-up.

- Objective: To determine short and midterm outcomes of a pre-loaded fenestrated thoracic endograft (f-TEVAR) for exclusion of distal aortic arch pathologies.Methods: This was a multicentre, retrospective study including consecutive patients from six experienced European vascular centres undergoing f-TEVAR for distal arch pathologies. Primary endpoints included peri-operative mortality and peri-operative stroke and/or spinal cord ischaemia rates. Secondary outcomes were technical success and mid to late events, including death and re-interventions. Statistical analysis was performed with SPSS 26. Mid to late term events were calculated using Kaplan–Meier survival analysis.Results: One hundred and eight patients were included (mean age 68 ± 11 years, 70% men). A total of 38% (n = 42) had a prior history of aortic dissection, and 24% (n = 26) prior aortic surgery. The mean aneurysm diameter was 59 ± 12 mm and the most frequent indication for treatment was post-dissection aneurysms (n = 42, 39%). Technical success was 99% (n = 107) despite intra-operative wire entanglement occurring in 29% (n = 31). The 30 day mortality rate was 3.7% (n = 4), with a 5.6% major stroke incidence (n = 6) and 3.7% (n = 4) spinal cord ischaemia rate. Three cases of retrograde dissection occurred (two of which were fatal), all in post-type B dissecting aneurysm patients without prior aortic surgery (three of 19, 15.8%). Median follow up was 12 months (range, 1 – 26). Endoleaks were documented during follow up, with 3.5% type Ia (4/104) and 2.9% type Ib (3/104) as a result of persistent false lumen perfusion. The one, two, and three year survivals and freedom from re-intervention rates were 93.2% and 92.1%, 89.1% and 86.3%, and 84.4% and 73%, respectively.Conclusion: This multicentre study shows that treatment of the distal aortic arch by f-TEVAR is feasible, with promising 30 day mortality, stroke, and spinal cord ischaemia rates.

- Objective: Analyze the outcomes of endovascular complex abdominal and thoracoabdominal aortic aneurysm repair using the Cook fenestrated device with the modified preloaded delivery system (MPDS) with a biport handle and preloaded catheters. Methods: A multicenter retrospective single arm cohort study was performed, including all consecutive patients with complex abdominal aortic aneurysm repair and thoracoabdominal aortic aneurysms treated with the MPDS fenestrated device (Cook Medical). Patient clinical characteristics, anatomy, and indications for device use were collected. Outcomes, classified according to the Society for Vascular Surgery reporting standards, were collected at discharge, 30 days, 6 months, and annually thereafter. Results: Overall, 712 patients (median age, 73 years; interquartile range [IQR], 68-78 years; 83% male) from 16 centers in Europe and the United States treated electively were included: 35.4% (n = 252) presented with thoracoabdominal aortic aneurysms and 64.6% (n = 460) with complex abdominal aortic aneurysm repair. Overall, 2755 target vessels were included (mean, 3.9 per patient). Of these, 1628 were incorporated via ipsilateral preloads using the MPDS (1440 accessed from the biport handle and 188 from above). The mean size of the contralateral femoral sheath during target vessel catheterization was 15F ± 4, and in 41 patients (6.7%) the sheath size was ≤8F. Technical success was 96.1%. Median procedural time was 209 minutes (IQR, 161-270 minutes), contrast volume was 100 mL (IQR, 70-150mL), fluoroscopy time was 63.9 minutes (IQR, 49.7-80.4 minutes) and median cumulative air kerma radiation dose was 2630 mGy (IQR, 838-5251 mGy). Thirty-day mortality was 4.8% (n = 34). Access complications occurred in 6.8% (n = 48) and 30-day reintervention in 7% (n = 50; 18 branch related). Follow-up of >30 days was available for 628 patients (88%), with a median follow-up of 19 months (IQR, 8-39 months). Branch-related endoleaks (type Ic/IIIc) were observed in 15 patients (2.6%) and aneurysm growth of >5 mm was observed in 54 (9.5%). Freedom from reintervention at 12 and 24 months was 87.1% (standard error [SE],1.5%) and 79.2% (SE, 2.0%), respectively. Overall target vessel patency at 12 and 24 months was 98.6% (SE, 0.3%) and 96.8% (SE, 0.4%), respectively, and was 97.9% (SE, 0.4%) and 95.3% (SE, 0.8%) for arteries stented from below using the MPDS, respectively. Conclusions: The MPDS is safe and effective. Overall benefits include a decrease in contralateral sheath size in the treatment of complex anatomies with favorable results.

- OBJECTIVE: The objective of this study was to evaluate the outcome of endovascular aortic arch repair for chronic dissection with a custom-made branched endograft.BACKGROUND: Acute type A aortic dissections are often treated with prosthetic replacement of the ascending aorta. During follow-up, repair of an aneurysmal evolution of the false lumen distal to the ascending prosthesis can be a challenge both for the surgeon and the patient.METHODS: We conducted a multicenter, retrospective study of consecutive patients from 14 vascular units treated with a custom-made, inner-branched device (Cook Medical, Bloomington, IN) for chronic aortic arch dissection. Rates of in-hospital mortality and stroke, technical success, early and late complications, reinterventions, and mortality during follow-up were evaluated.RESULTS: Seventy consecutive patients were treated between 2011 and 2018. All patients were considered unfit for conventional surgery. In-hospital combined mortality and stroke rate was 4% (n = 3), including 1 minor stroke, 1 major stroke causing death, and 1 death following multiorgan failure. Technical success rate was 94.3%. Twelve (17.1%) patients required early reinterventions: 8 for vascular access complication, 2 for endoleak correction, and 2 for pericardial effusion drainage. Median follow-up was 301 (138-642) days. During follow-up, 20 (29%) patients underwent secondary interventions: 9 endoleak corrections, 1 open repair for prosthetic kink, and 10 distal extensions of the graft to the thoracic or thoracoabdominal aorta. Eight patients (11%) died during follow-up because of nonaortic-related cause in 7 cases.CONCLUSIONS: Endovascular treatment of aortic arch chronic dissections with a branched endograft is associated with low mortality and stroke rates but has a high reintervention rate. Further follow-up is required to confirm the benefits of this novel approach.

- BACKGROUND: Timely assessment of the burden of HIV/AIDS is essential for policy setting and programme evaluation. In this report from the Global Burden of Disease Study 2015 (GBD 2015), we provide national estimates of levels and trends of HIV/AIDS incidence, prevalence, coverage of antiretroviral therapy (ART), and mortality for 195 countries and territories from 1980 to 2015.METHODS: For countries without high-quality vital registration data, we estimated prevalence and incidence with data from antenatal care clinics and population-based seroprevalence surveys, and with assumptions by age and sex on initial CD4 distribution at infection, CD4 progression rates (probability of progression from higher to lower CD4 cell-count category), on and off antiretroviral therapy (ART) mortality, and mortality from all other causes. Our estimation strategy links the GBD 2015 assessment of all-cause mortality and estimation of incidence and prevalence so that for each draw from the uncertainty distribution all assumptions used in each step are internally consistent. We estimated incidence, prevalence, and death with GBD versions of the Estimation and Projection Package (EPP) and Spectrum software originally developed by the Joint United Nations Programme on HIV/AIDS (UNAIDS). We used an open-source version of EPP and recoded Spectrum for speed, and used updated assumptions from systematic reviews of the literature and GBD demographic data. For countries with high-quality vital registration data, we developed the cohort incidence bias adjustment model to estimate HIV incidence and prevalence largely from the number of deaths caused by HIV recorded in cause-of-death statistics. We corrected these statistics for garbage coding and HIV misclassification.FINDINGS: Global HIV incidence reached its peak in 1997, at 3·3 million new infections (95% uncertainty interval [UI] 3·1-3·4 million). Annual incidence has stayed relatively constant at about 2·6 million per year (range 2·5-2·8 million) since 2005, after a period of fast decline between 1997 and 2005. The number of people living with HIV/AIDS has been steadily increasing and reached 38·8 million (95% UI 37·6-40·4 million) in 2015. At the same time, HIV/AIDS mortality has been declining at a steady pace, from a peak of 1·8 million deaths (95% UI 1·7-1·9 million) in 2005, to 1·2 million deaths (1·1-1·3 million) in 2015. We recorded substantial heterogeneity in the levels and trends of HIV/AIDS across countries. Although many countries have experienced decreases in HIV/AIDS mortality and in annual new infections, other countries have had slowdowns or increases in rates of change in annual new infections.INTERPRETATION: Scale-up of ART and prevention of mother-to-child transmission has been one of the great successes of global health in the past two decades. However, in the past decade, progress in reducing new infections has been slow, development assistance for health devoted to HIV has stagnated, and resources for health in low-income countries have grown slowly. Achievement of the new ambitious goals for HIV enshrined in Sustainable Development Goal 3 and the 90-90-90 UNAIDS targets will be challenging, and will need continued efforts from governments and international agencies in the next 15 years to end AIDS by 2030.

- ObjectiveThe European Society for Vascular Surgery (ESVS) has developed clinical practice guidelines for the care of patients with aneurysms of the abdominal aorta and iliac arteries in succession to the 2011 and 2019 versions, with the aim of assisting physicians and patients in selecting the best management strategy.MethodsThe guideline is based on scientific evidence completed with expert opinion on the matter. By summarising and evaluating the best available evidence, recommendations for the evaluation and treatment of patients have been formulated. The recommendations are graded according to a modified European Society of Cardiology grading system, where the strength (class) of each recommendation is graded from I to III and the letters A to C mark the level of evidence.ResultsA total of 160 recommendations have been issued on the following topics: Service standards, including surgical volume and training; Epidemiology, diagnosis, and screening; Management of patients with small abdominal aortic aneurysm (AAA), including surveillance, cardiovascular risk reduction, and indication for repair; Elective AAA repair, including operative risk assessment, open and endovascular repair, and early complications; Ruptured and symptomatic AAA, including peri-operative management, such as permissive hypotension and use of aortic occlusion balloon, open and endovascular repair, and early complications, such as abdominal compartment syndrome and colonic ischaemia; Long term outcome and follow up after AAA repair, including graft infection, endoleaks and follow up routines; Management of complex AAA, including open and endovascular repair; Management of iliac artery aneurysm, including indication for repair and open and endovascular repair; and Miscellaneous aortic problems, including mycotic, inflammatory, and saccular aortic aneurysm. In addition, Shared decision making is being addressed, with supporting information for patients, and Unresolved issues are discussed.ConclusionThe ESVS Clinical Practice Guidelines provide the most comprehensive, up to date, and unbiased advice to clinicians and patients on the management of abdominal aorto-iliac artery aneurysms.
