- Background: Thoracic endovascular aortic repair (TEVAR) can be challenging in cases involving the aortic arch and the visceral segment. We report our initial experience with fenestrated TEVAR (f-TEVAR) for thoracic aortic disease involving aortic branches using physician-modified stent grafts (PMSGs). Methods: Between February 2019 and November 2020 nine patients were treated with a PMSG. Indication to treatment were a symptomatic acute type B aortic dissection (TBAD) in three cases, a penetrating aortic ulcer in three cases (two in zone 3 and one in zone 6), one case of an endoleak type IA after TEVAR, a chronic TBAD after TEVAR in one case and one case of a contained rupture of a thoracoabdominal aneurysm in zone 3. Pre-, intra-and postoperative clinical data were recorded. Results: The median patient age was 65 (IQR 60.5-71) years, and eight (89%) patients were men. Nine stent grafts (six Bolton Relay Plus and three Bolton Relay Pro, Terumo Aortic, Vascutek Ltd., Inchinnan, UK) were deployed. Small fenestrations (8 mm) were created on table, median duration for on table stent graft modifications was 20 minutes (range 13-22). The technical success rate was 100%. Median operative time was 188 (range 116-252) minutes. No major adverse events of any sort occurred during the first 30-day postoperatively. There were no type I or type III endoleaks at the end of the procedure, and no cases of spinal cord ischemia. Two access related complications occurred (22%). After a median of 12 (range 5-12) months all patients survived and all target vessels remained patent with one case of fenestration-related type I endoleak, which required open conversion. Conclusions: The results of our initial experience with f-TEVAR using PMSGs with the Bolton Relay stentgraft for the treatment of aortic diseases are acceptable. These results should be confirmed on larger patient cohorts. (Cite this article as: Asciutto G, Usai MV, Ibrahim A, Oberhuber A.

- The market of aortic endografts is in continuous development. Several endografts that have gained the CE mark are under investigation by the FDA before launching in the US market. This chapter describes their peculiarities and the evidence acquired with the use of these endografts. Since the majority of the devices described in this chapter have been recently introduced, the evidence on the feasibility of their use in the treatment of aortic aneurysm is limited. The available data report of short-term results in terms of patency, freedom from Types I and III endoleak (EL), and freedom from aneurysm sac enlargement is comparable to those of devices that have been longer in use.

- Objective: The use of intravascular ultrasound (IVUS) reduces contrast medium use and radiation exposure during conventional endovascular aneurysm repair (EVAR). The aim of this study was to evaluate the safety and efficacy of IVUS in detecting bridging stent graft (bSG) instability during fenestrated and branched EVAR (F/B-EVAR).Methods: This was a prospective observational multicentre study. The following outcomes were evaluated: (1) technical success of the IVUS in each bSG, (2) IVUS findings compared with intra-operative angiography, (3) incidence of post-operative computed tomography angiography (CTA) findings not detected with IVUS, and (4) absence of IVUS related adverse events. Target visceral vessel (TVV) instability was defined as any branch or fenestration issues requiring an additional manoeuvre or re-intervention. Any IVUS assessment that detected stenosis, kinking, or any geometric TVV issue was considered to be branch instability. All procedures were performed in ad hoc hybrid rooms.Results: Eighty patients (69% males; median age 72 years; interquartile range 59, 77 years) from four aortic centres treated with F/B-EVAR between January 2019 and September 2021 were included: 70 BEVAR (21 off the shelf; 49 custom made), eight FEVAR (custom made), and two F/B-EVAR (custom made), for a total of 300 potential TVVs. Two TVVs (0.7%) were left unstented and excluded from the analysis. The TVVs could not be accessed with the IVUS catheter in seven cases (2.3%). Furthermore, 17 (5.7%) TVVs could not be examined due to a malfunction of the IVUS catheter. The technical success of the IVUS assessment was 91.9% (274/298), with no IVUS related adverse events. Seven TVVs (2.5%) showed signs of bSG instability by means of IVUS, leading to immediate revisions. The first post-operative CTA at least 30 days after the index procedure was available in 268 of the 274 TVVs originally assessed by IVUS. In seven of the 268 TVVs (2.6%) a re-intervention became necessary due to bSG instability.Conclusion: This study suggests that IVUS is a safe and potentially valuable adjunctive imaging technology for intra-operative detection of TVV instability. Further long term investigations on larger cohorts are required to validate these promising results and to compare IVUS with alternative technologies in terms of efficiency, radiation exposure, procedure time, and costs.

- Purpose: The purpose of this report is to describe the use of a double-branched custom-made iliac branch device (IBD) for the endovascular repair of an aorto-bi-iliac aneurysm with concomitant bilateral hypogastric aneurysms. Technique: A 61-year-old man on peritoneal dialysis underwent a computed tomography (CT) of the infrarenal aorta before planned kidney transplantation. The CT showed an asymptomatic aorto-bi-iliac aneurysm of 54 mm involving the hypogastric artery (HA) bilaterally (right HA 31 mm; left HA 40 mm). The treatment consisted of an endovascular aortic repair (EVAR) and the bilateral implantation of custom-manufactured IBDs with double inner branches to preserve both superior and inferior gluteal arteries. At 1 year follow-up, the patient remains free of symptoms and the postoperative CT showed a successfully excluded aneurysm with patent bridging stent grafts to all HA branches. Conclusion: The bilateral implantation of double-branched IBDs is a feasible technique. Preservation of both hypogastric arteries and its branches can be achieved with this technique and therefore decrease the risk of buttock claudication and other ischemic complications.

- Background: Post-implantation syndrome (PIS) is defined as non-infectious continuous fever and a concomitant rise in inflammatory markers shortly after endovascular aortic repair. PIS occurrence after hybrid procedures, such as the frozen elephant trunk (FET) technique, has not been adequately investigated. The current study aims to define the incidence of PIS after the FET and to identify possible risk factors associated with its occurrence. Methods: The clinical charts of 59 patients undergoing the FET between February 2015 and April 2020 were reviewed retrospectively. The occurrence of PIS was defined as the presence of fever (>38 degrees C lasting longer than one day during the hospitalisation) and leucocytosis (white blood cell count >12,000/mu L). Patients with concomitant conditions possibly leading to fever and/or leucocytosis were excluded. Beside demographic and procedure-related data, serum/plasma inflammatory markers were evaluated before surgery and daily up to seven days postoperatively. Computed tomography scans (CT) were examined to calculate the volume of pre-existent and new-onset mural thrombus after the FET. Results: Thirty-eight patients met the inclusion criteria. The study cohort was divided into two groups based on the occurrence of PIS (17 cases; 44.7%). Patients with PIS were significantly younger than those without PIS (53.5 +/- 8.9 vs. 62.5 +/- 9.6 years; P=0.005). Female patients were less likely to develop PIS (5.2% vs. 26.3%, P=0.018). Patients with PIS had a higher volume of new-onset thrombus in the postoperative CT (P<0.001). Patients treated for post-dissection aneurysm had, postoperatively, significantly more thrombus material developed in a false lumen (P=0.02). Among the PIS markers, CRP (C-reactive protein) levels on the third postoperative day were independently associated with the volume of new-onset thrombus (P=0.011). After multivariate analysis, the volume of new-onset thrombus (P=0.028) and age (P=0.036) remained the variable associated with a statistically significant increased incidence of PIS. Conclusions: PIS can occur after the frozen elephant trunk procedure. The volume of new-onset thrombus seems to be associated with an increased incidence of PIS. These findings need to be confirmed in larger patient cohorts.

Tidskriftsartikel (refereegranskat)abstract
- Objective: Treatment of complex aortic aneurysms with the in situ laser fenestration (ISLF) technique involves implantation of a balloon expandable stent graft (bSG) in the created fenestration. Adequate expansion of this bSG is of importance both to achieve seal and to ensure target vessel stability. This experimental study assessed the expansion rate of different bSGs in the ISLF setting using intravascular ultrasound (IVUS).Methods: A commercially available aortic endograft was used to test the laser fenestration technique (Zenith Alpha, Cook Medical LLC, Bloomington, IN, USA). The ISLF was stented with the following bSGs: two Gore Viabahn VBX balloon expandable endoprostheses (WL Gore & Associates, Bloomington, IL, USA), three BeGraft Peripheral and three BeGraft Plus (Bentley InnoMed GmbH; Hechingen, Germany), and three Advanta V12 (Atrium, Hudson, NH, USA). The bSGs were expanded in three steps: (1) nominal, (2) rated burst pressure, and (3) dilation with a non-compliant balloon at 15 atmospheres. After each step, an IVUS assessment of the bSG minimum diameter and the area at the fenestration (FA) and in a fully expanded segment distal to the fenestration (SA) was performed. A mean of the three IVUS measurements was used as the value for comparison. An insufficient bSG expansion was defined as a mean of FA/SA of <0.8 (i.e., <80% expansion).Results: The VBX was the only bSG that could be expanded to its intended diameter (i.e., at least 80%) at nominal pressure. The BeGraft Peripheral and BeGraft Plus had the lowest degree of expansion after nominal and rated burst pressure. All bSGs that were tested reached a sufficient expansion degree after using a higher pressure balloon.Conclusion: In this ex vivo experiment, dilation up to nominal pressure showed satisfactory expansion only for the VBX. The consistency of the results when applied to the different types of stent grafts that were analysed reflects structural stent graft specific issues to consider when choosing the right device in cases of ISLF.

Tidskriftsartikel (refereegranskat)abstract
- AIM: While the scientific evidence in favour of negative pressure wound therapy (NPWT) dressings on sutured incisions in the prevention of surgical site infections (SSIs) has increased, the cost-effectiveness after vascular surgery has not been evaluated. The aim of this study was to evaluate the cost-effectiveness of NPWT compared to standard dressings for the prevention of SSIs after open inguinal vascular surgery.MATERIALS AND METHODS: Patient data were retrieved from the randomised INVIPS-trial's open arm, which included patients randomised to either NPWT or standard dressings. The patients were surveyed for SSIs for 90 days postoperatively. The patients' individual cost data were included and analysed from a healthcare perspective. The patients' quality of life was measured using the Vascuqol-6 questionnaire pre- and 30 days postoperatively. Cost-effectiveness of NPWT was determined by decreased or equal total costs and a significant reduction in SSI incidence.RESULTS: The mean vascular procedure-related costs at 90 days were €16,621 for patients treated with NPWT (n = 59) and €16,285 for patients treated with standard dressings (n = 60), p = 0.85. The SSI incidence in patients treated with NPWT was 11.9% (n = 7/59) compared to 30.0% (n = 18/60) with standard dressings, p = 0.015. This corresponds to an increased mean cost of €1,853 per SSI avoided. The cost-effectiveness plane of incremental vascular procedure-related costs and difference in Vascuqol-6 score showed that 42% of estimates were in the quadrant where NPWT was dominant.CONCLUSION: NPWT is considered cost-effective over standard dressings in patients undergoing open inguinal vascular surgery due to reduced SSI incidence at no higher costs.

- Background Surgical site infections (SSI) in the groin after vascular surgery are common. The aim of the study was to evaluate the effect of negative pressure wound therapy (NPWT) on SSI incidence when applied on closed inguinal incisions after endovascular aneurysm repair (EVAR). Methods A multicenter randomized controlled trial (RCT). Between November 2013 and December 2020, 377 incisions (336 bilateral and 41 unilateral) from elective EVAR procedures with the primary intent of fascia closure were randomized and included, receiving either NPWT or a standard dressing. In bilateral incisions, each incision randomly received the opposite dressing of the other side, thereby becoming each others control. The primary endpoint was SSI incidence at 90 days postoperatively, analyzed on an intention-to-treat basis. Uni and bilaterally operated incisions were analyzed separately, and their respective p-values combined using Fishers method for combining P-values. Study protocol (NCT01913132). Results The SSI incidence at 90 days postoperatively in bilateral incisions was 1.8% (n = 3/168) in the NPWT and 4.8% (n = 8/168) in the standard dressing group, and in unilateral incisions 13.3% (n = 2/15) and 11.5% (n = 3/26), respectively (combined p = 0.49). In all SSIs, bacteria were isolated from incisional wound cultures. No additional SSIs were diagnosed between 90 days and 1 year follow-up. Conclusions No evidence of difference in SSI incidence was seen in these low-risk inguinal incisions when comparing NPWT with standard dressings after EVAR with the primary intent of fascia closure.

- INTRODUCTION: Surgical endarterectomy represents the gold standard for the treatment of atherosclerotic lesions of the groin vessels. Endovascular treatment such as atherectomy with or without drug coated angioplasty (DCA) of the so called no stenting zones, i.e. inguinal and popliteal vessels, is gaining growing acceptance as alternative option to open surgery. This systematic review aims to scrutiny the current clinical evidence regarding atherectomy and DCA for the common artery (CFA).EVIDENCE ACQUISITION: We conducted an exhaustive research in multiple platforms (Medline, PubMed, Cochrane, Google Scholar, Em base) on studies over atherectomy and angioplasty for inguinal atherosclerotic lesions published between 2000 and 2021. As search strategy we used a wide list of MeSH items, words, synonyms. Bibliographies of review articles were checked for further relating studies regarding atherectomy of CFA. A qualitative and quantitative data analysis was carried out.EVIDENCE SYNTHESIS: Fifteen studies were included in the qualitative review. Not all studies were focused only on atherectomy of inguinal vessels, despite including such treatment. Hence, data regarding this treatment were not exhaustive. A fairly homogeneous data analysis was possible in 7 of 15 studies. The remaining 8 studies were qualitatively analyzed but not included in the statistical analysis. In all 7 included studies directional atherectomy and DCA under filter protection were carried out. In this subgroup, overall, 497 patients were treated with atherectomy. Sixty-eight percent of the patients were males. Rutherford class from 1-3 dominated against 4-6 (63% vs. 37%). Mean technical success rate was 96%, with a primary and secondary patency rate of 92% and 98% respectively at one year. Procedure related vascular complications ranged from 1% to 6%.CONCLUSIONS: Current literature about atherectomy for inguinal arteries is scant, data are inhomogeneous and so are treatment modalities. Nevertheless, the results of this systematic review suggest that this endovascular strategy is feasible with good short and midterm results. Prospective trials with larger patient cohorts are necessary to confirm these preliminary results.
