- Objective: To develop a minimum core data set for evaluation of acute limb ischaemia (ALI) revascularisation treatment and outcomes that would enable collaboration among international registries. Methods: A modified Delphi approach was used to achieve consensus among international multidisciplinary vascular specialists and registry members of the International Consortium of Vascular Registries (ICVR). Variables identified in the literature or suggested by the expert panel, and variables, including definitions, currently used in 15 countries in the ICVR, were assessed to define both a minimum core and an optimum data set to register ALI treatment. Clinical relevance and practicability were both assessed, and consensus was defined as >= 80% agreement among participants. Results: Of 40 invited experts, 37 completed a preliminary survey and 31 completed the two subsequent Delphi rounds via internet exchange and face to face discussions. In total, 117 different items were generated from the various registry data forms, an extensive review of the literature, and additional suggestions from the experts, for potential inclusion in the data set. Ultimately, 35 items were recommended for inclusion in the minimum core data set, including 23 core items important for all registries, and an additional 12 more specific items for registries capable of capturing more detail. These 35 items supplement previous data elements recommended for registering chronic peripheral arterial occlusive disease treatment. Conclusion: A modified Delphi study allowed 37 international vascular registry experts to achieve a consensus recommendation for a minimum core and an optimum data set for registries covering patients who undergo ALI revascularisation. Continued global harmonisation of registry infrastructure and definition of items allows international comparisons and global quality improvement. Furthermore, it can help to define and monitor standards of care and enable international research collaboration.

- Background: The need for anticoagulation therapy (AC) in patients with subsegmental pulmonary embolism (SSPE) diagnosed by computed tomography of the pulmonary arteries (CTPA) has been questioned, as these patients run low risk for recurrent venous thromboembolism (VTE) during 3 months of follow-up. Whether this applies also to patients with small PE diagnosed with pulmonary scintigraphy has not yet been evaluated, however. Methods: We therefore retrospectively evaluated 54 patients (mean age 62 ± 19 years, 36 [67 %] women) with small PE diagnosed by ventilation/perfusion singe photon emission computed tomography (V/P SPECT) who did not receive conventional long-term AC. Results: More than half of our patients (36[67 %]) received less than 48 h of AC, 11 (20 %) patients were treated for 2-14 days, and 7 (13 %) for 15-30 days. The majority (28 [52 %]) of our patients had a non-low simplified pulmonary emboli severity index (S-PESI), and 7 (13 %) had malignancy. D-dimer was negative in 18 (33 %), positive in 10 (19 %), and not analyzed in 28 (52 %) patients. Phlebography of the lower extremities had been performed with negative result in one patient. During 90 days of follow up no deaths or PE occurred. Seven patients were readmitted to hospital, whereof two (2/54 [4 %]) were diagnosed with deep venous thrombosis (DVT) necessitating AC therapy. Conclusion: In conclusion, withholding longterm AC therapy in patients with SSPE diagnosed by V/P SPECT resulted in 4 % risk for recurrence of VTE during 90 days of follow up, and can therefore currently not be recommended.

- Objective: To explore the effects of baroreflex activation therapy (BAT) on hypertension in patients with treatment resistant or refractory hypertension.Methods: This investigator-initiated randomized, double-blind, 1:1 parallel-design clinical trial will include 100 patients with refractory hypertension from 6 tertiary referral hypertension centers in the Nordic countries. A Barostim Neo System will be implanted and after 1 month patients will be randomized to either BAT for 16 months or continuous pharmacotherapy (BAT off) for 8 months followed by BAT for 8 months. A second randomization will take place after 16 months to BAT or BAT off for 3 months. Eligible patients have a daytime systolic ambulatory blood pressure (ABPM) of 145mm Hg, and/or a daytime diastolic ABPM of 95mm Hg after witnessed drug intake (including 3 antihypertensive drugs, preferably including a diuretic).Results: The primary end point is the reduction in 24-hour systolic ABPM by BAT at 8 months, as compared to pharmacotherapy. Secondary and tertiary endpoints are effects of BAT on home and office blood pressures, measures of indices of cardiac and vascular structure and function during follow-up, and safety.Conclusions: This academic initiative will increase the understanding of mechanisms and role of BAT in the refractory hypertension.

- Objective: Invasive treatment of peripheral arterial disease (PAD) does not always lead to improvement, as concomitant diseases might affect walking ability and health related quality of life (HRQoL). Patients with chronic widespread pain (CWP) report worse outcome when treated for cancer and rheumatic diseases. The aim of the present study was to evaluate the prevalence of CWP and its potential association with reduced HRQoL in patients treated for PAD. Method: This was a longitudinal cohort study conducted between May 2011 and April 2014, including patients with planned invasive treatment of symptomatic PAD at two vascular clinics in Sweden. In 240 patients with planned treatment of PAD, HRQoL and pain distribution were assessed using the Short Form 36 Health Survey (SF-36), EuroQoL 5 dimensions (EQ5D), Walking Impairment Questionnaire (WIQ), and a questionnaire concerning musculoskeletal pain (Epipain manikin) before and 12 months after treatment. HRQoL was compared in patients with no chronic pain (NCP), with chronic regional pain (CRP), and with CWP. The SF-36 subscales PF, VT, and MH, representing important aspects of HRQoL (physical function, vitality, and mental health), were the main outcome measures. Results: Before treatment 22 (10%) patients reported NCP, 133 (61%) CRP, and 64 (29%) CWP. These proportions did not differ between patients with intermittent claudication (IC) and critical limb ischemia (CLI, p =.150). CWP was more common in women than in men (36% vs. 24%, p =.035.) HRQoL improved significantly after treatment in all groups, but was still significantly reduced in CWP patients. CWP predicted worse outcome in HRQoL after treatment. Conclusion: CWP is common and is strongly associated with reduced HRQoL in patients with PAD. Treatment led to significant improvement, but patients with CWP still had significantly reduced HRQoL after treatment. CWP measured by a pain manikin should therefore be taken into account when evaluating disease severity, treatment options, and effect of treatment in PAD.

Tidskriftsartikel (refereegranskat)abstract
- Background: Invasive treatment of intermittent claudication (IC) because of severe atherosclerotic stenosis or occlusion in the superficial femoral artery (SFA) is controversial. This prospective randomised trial was performed to assess the impact on health related quality of life (HRQoL) of primary stenting with nitinol self expanding stents compared with best medical treatment alone in patients suffering from stable IC due to SFA disease. Methods: One hundred patients with stable IC caused by SFA disease from seven Swedish hospitals treated with best medical treatment (BMT) were randomised to either the stent (n = 48) or the control (n = 52) group. Change in HRQoL assessed by the Short Form 36 Health Survey (SF-36) and EuroQoL 5 dimensions (EQ5D) 12 months after treatment was the primary outcome measure. Improvement in the Walking Impairment Questionnaire (WIQ), ankle brachial index (ABI), and walking distance were secondary outcomes. Results: HRQoL improved significantly. In the stent group the following SF-36 domains improved: Physical Function, 19 points (p <.001); Bodily Pain, 14 points (p =.001); General Health, 6 points (p =.019); Vitality, 10 points (p =.004); Physical Component Summary, 6.5 points (p <.001); EQ5D, 0.14 points (p =.008); and WIQ 22 points (p <.001). They were unchanged in the control group. Both ABI (from 0.58 +/- 0.11 to 0.86 +/- 0.19, p <.001, in the stent group and from 0.63 +/- 0.17 to 0.70 +/- 0.20, p =.005, in the control group) and walking distance (WD) (from 171 +/- 90 meters to 613 +/- 381 meters, p <.001, in the stent group and from 209 +/- 106 m to 335 +/- 321 meters, p =.012, in the control group) improved, and at 12 months both the ABI (p <.001) and the WD (p =.001) were higher in the stent group. Conclusions: In patients with IC caused by lesions in the SFA, the addition of primary stenting to BMT was associated with significant improvement in HRQoL, ABI, and walking distance after 12 months follow-up compared with BMT alone.

- Purpose: The main aim of this study was to evaluate the association of computed tomography (CT) findings at admission and bowel resection rate in patients with mesenteric venous thrombosis (MVT). It was hypothesized that abnormal intestinal findings on CT were associated with a higher bowel resection rate. Methods: Retrospective study of MVT patients treated between 2004 and 2017. CT images at admission and at follow-up were scrutinized according to a predefined protocol. Successful recanalization was defined as partial or complete recanalization of the portomesenteric venous thrombosis at the latest CT follow-up (n = 70). Results: We studied 102 patients (median age 58 years, 61 men). Lifelong anticoagulation was initiated in 64 patients, and bowel resection rate was 17%. No referral letter indicated suspicion of MVT, whereas three indicated suspected intestinal ischemia. Previous venous thromboembolism was associated with increased bowel resection rate (p = 0.049). No patient with acute pancreatitis (n = 17) underwent bowel resection (p = 0.068). The presence of mesenteric oedema (p = 0.014), small bowel wall oedema (p < 0.001), small bowel dilatation (p = 0.005), and ascites (p = 0.021) were associated with increased bowel resection rate. Small bowel wall oedema remained as an independent risk factor associated with bowel resection (OR 15.8 [95% CI 3.2–77.2]). Successful thrombus recanalization was achieved in 66% of patients. Conclusion: The presence of abnormal intestinal findings secondary to MVT confers an excess risk of need of bowel resection due to infarction. Responsible physicians should therefore scrutinize the CT images at diagnosis together with the radiologist to better tailor clinical surveillance.
