- Background: Diagnosis of acute mesenteric ischaemia in the early stages is now possible with modern computed tomography (CT), using intravenous contrast enhancement and imaging in the arterial and/or portal venous phase. The availability of CT around the clock means that more patients with acute mesenteric ischaemia may be treated with urgent intestinal revascularization.Methods: This was a review of modern treatment strategies for acute mesenteric ischaemia.Results: Endovascular therapy has become an important alternative, especially in patients with acute thrombotic superior mesenteric artery (SMA) occlusion, where the occlusive lesion can be recanalized either antegradely from the femoral or brachial artery, or retrogradely from an exposed SMA after laparotomy, and stented. Aspiration embolectomy, thrombolysis and open surgical embolectomy, followed by on-table angiography, are the treatment options for embolic SMA occlusion. Endovascular therapy may be an option in the few patients with mesenteric venous thrombosis who do not respond to anticoagulation therapy. Laparotomy is needed to evaluate the extent and severity of visceral organ ischaemia, which is treated according to the principles of damage control surgery.Conclusion: Modern treatment of acute mesenteric ischaemia involves a specialized approach that considers surgical and, increasingly, endovascular options for best outcomes.

- BackgroundIndications for negative-pressure wound therapy (NPWT) in vascular surgical patients are expanding. The aim of this review was to outline the evidence for NPWT on open and closed wounds. MethodsA PubMed, EMBASE and Cochrane Library search from 2007 to June 2016 was performed combining the medical subject headings terms wound infection', abdominal aortic aneurysm (AAA)', fasciotomy', vascular surgery' and NPWT' or VAC'. ResultsNPWT of open infected groin wounds was associated with shorter duration of wound healing by 47 days, and was more cost-effective than alginate dressings in one RCT. In one RCT and six observational studies, NPWT-related major bleeding and graft preservation rates were 0-10 and 83-100 per cent respectively. One retrospective comparative study showed greater wound size reduction per day, fewer dressing changes, quicker wound closure and shorter hospital stay with NPWT compared with gauze dressings for lower leg fasciotomy. NPWT and mesh-mediated fascial traction after AAA repair and open abdomen was associated with high primary fascial closure rates (96-100 per cent) and low risk of graft infection (0-7 per cent). One retrospective comparative study showed a significant reduction in surgical-site infection, from 30 per cent with standard wound care to 6 per cent with closed incisional NPWT. ConclusionNPWT has a central role in open and infected wounds after vascular surgery; the results of prophylactic care of closed incisions are promising.

- 2016
-

Forskningsöversikt (refereegranskat)abstract
- Objectives: The aim of this paper was to review the literature on temporary abdominal closure (TAC) after abdominal aortic aneurysm (AAA) repair. Methods: This was a systematic review of observational studies. A PubMed, EM BASE and Cochrane search from 2007 to July 2015 was performed combining the Medical Subject Headings "aortic aneurysm" and "temporary abdominal closure", "delayed abdominal closure", "open abdomen", "abdominal compartment syndrome", "negative pressure wound therapy", or "vacuum assisted wound closure". Results: Seven original studies were found. The methods used for TAC were the vacuum pack system with (n = 1) or without (n = 2) mesh bridge, vacuum assisted wound closure (VAWC; n = 1) and the VAWC with mesh mediated fascial traction (VACM; n = 3). The number of patients included varied from four to 30. Three studies were exclusively after open repair, one after endovascular aneurysm repair, and three were mixed series. The frequency of ruptured AAA varied from 60% to 100%. The primary fascia] closure rate varied from 79% to 100%. The median time to closure of the open abdomen was 10.5 and 17 days in two prospective studies with a fascia] closure rate of 100% and 96%, respectively; the inclusion criterion was an anticipated open abdomen therapy time >= 5 days using the VACM method. The graft infection rate was 0% in three studies. No patient with longterm open abdomen therapy with the VACM in the three studies was left with a planned ventral hernia. The in hospital survival rate varied from 46% to 80%. Conclusions: A high fascial closure rate without planned ventral hernia is possible to achieve with VACM, even after long-term open abdomen therapy. There are, however, few publications reporting specific results of open abdomen treatment after AAA repair, and there is a need for randomized controlled trials to determine the most efficient and safe TAC method during open abdomen treatment after AAA repair.

- Background: The aim of this paper was to review the literature on vacuum-Assisted wound closure and mesh-mediated fascial traction (VAWCM) in open abdomen therapy. It was designed as systematic review of observational studies. Methods: A Pub Med, EMBASE and Cochrane search from 2007/01-2016/07 was performed combining the Medical Subject Headings "vacuum", "mesh-mediated fascial traction", "temporary abdominal closure", "delayed abdominal closure", "open abdomen", "abdominal compartment syndrome", "negative pressure wound therapy" or "vacuum assisted wound closure". Results: Eleven original studies were found including patients numbering from 7 to 111. Six studies were prospective and five were retrospective. Nine studies were on mixed surgical (n = 9), vascular (n = 6) and trauma (n = 6) patients, while two were exclusively on vascular patients. The primary fascial closure rate per protocol varied from 80-100%. The time to closure of the open abdomen varied between 9-32 days. The entero-Atmospheric fistula rate varied from 0-10.0%. The in-hospital survival rate varied from 57-100%. In the largest prospective study, the incisional hernia rate among survivors at 63 months of median follow-up was 54% (27/50), and 16 (33%) repairs out of 48 incisional hernias were performed throughout the study period. The study patients reported lower short form health survey (SF-36) scores than the mean reference population, mainly dependent on the prevalence of major co-morbidities. There was no difference in SF-36 scores or a modified ventral hernia pain questionnaire (VHPQ) at 5 years of follow up between those with versus those without incisional hernias. Conclusions: A high primary fascial closure rate can be achieved with the vacuum-Assisted wound closure and meshmediated fascial traction technique in elderly, mainly non-Trauma patients, in need of prolonged open abdomen therapy.

- Objective: A structured and transparent approach is instrumental in translating research evidence to health recommendations and evidence informed clinical decisions. The aim was to conduct an overview and analysis of principles and methodologies for health guideline development.Methods: A literature review on methodologies, strategies, and fundamental steps in the process of guideline development was performed. The clinical practice guideline development process and methodology adopted by the European Society for Vascular Surgery are also presented.Results: Sophisticated methodologies for health guideline development are being applied increasingly by national and international organisations. Their overarching principle is a systematic, structured, transparent, and iterative process that is aimed at making well informed healthcare choices. Critical steps in guideline development include the assessment of the certainty of the body of evidence; evidence to decision frameworks; and guideline reporting. The goal of strength of evidence assessments is to provide well reasoned judgements about the guideline developers’ confidence in study findings, and several evidence hierarchy schemes and evidence rating systems have been described for this purpose. Evidence to decision frameworks help guideline developers and users conceptualise and interpret the construct of the quality of the body of evidence. The most widely used evidence to decision frameworks are those developed by the GRADE Working Group and the WHO-INTEGRATE, and are structured into three distinct components: background; assessment; and conclusions. Health guideline reporting tools are employed to ensure methodological rigour and transparency in guideline development. Such reporting instruments include the AGREE II and RIGHT, with the former being used for guideline development and appraisal, as well as reporting.Conclusion: This guide will help guideline developers/expert panels enhance their methodology, and patients/clinicians/policymakers interpret guideline recommendations and put them in context. This document may be a useful methodological summary for health guideline development by other societies and organisations.

- This paper provides a summary of up-to-date information and experience with the combined treatment of patients suffering from peripheral arterial disease (PAD) with endovascular and open surgery, performed simultaneously and in a single operating room. Hybrid intervention is reported to have good results in well-indicated groups of patients with acute and chronic limb ischemia, even with older, high-risk patients. The indications for the use of this technique remain unclear with inconsistent opinions among vascular surgeons. The indications for treat-ment were divided into three main groups: 1) Patients with chronic limb ischemia, 2) acute limb ischemia, and 3) occlusion of a previous vascular reconstruction. The operating techniques for the most commonly used combinations are described. In conclusion, hybrid operating techniques are often useful when treating complex problems and multilevel disease in patients with chronic or acute lower limb ischemia. Modern vascular surgeons need to master both open and endovascular techniques, and to combine them in a creative fashion to the benefit of our patients.

Forskningsöversikt (refereegranskat)abstract
- INTRODUCTION: Definition, etiology, classification and indication for treatment of the arteriovenous access (AVA) aneurysm are poorly described in medical literature. The objectives of the paper are to complete this information gap according to the extensive review of the literature.METHODS: A literature search was performed of the articles published between April 1, 1967, and March 1, 2014. The databases searched included Medline and the Cochrane Database of Systematic Reviews. The eligibility criteria in this review studies the need to assess the association of aneurysms and pseudoaneurysms with autologous AVA. Aneurysms and pseudoaneurysms involving prosthetic AVA were not included in this literature review. From a total of 327 papers, 54 non-English papers, 40 case reports and 167 papers which did not meet the eligibility criteria were removed. The remaining 66 papers were reviewed.RESULTS: Based on the literature the indication for the treatment of an AVA aneurysm is its clinical presentation related to the patient's discomfort, bleeding prevention and inadequate access flow. A new classification system of AVA aneurysm, which divides it into the four types, was also suggested.CONCLUSIONS: AVA aneurysm is characterized by an enlargement of all three vessel layers with a diameter of more than 18 mm and can be presented in four types according to the presence of stenosis and/or thrombosis. The management of an AVA aneurysm depends on several factors including skin condition, clinical symptoms, ease of cannulation and access flow. The diameter of the AVA aneurysm as a solo parameter is not an indication for the treatment.

- Does screening of abdominal aortic aneurysm (AAA) fulfil the recently revised the World Health Organization WHO criteria for screening? Contemporary data from the literature are used to analyze whether the ten recent WHO criteria can be used to motivate AAA screening. Although the prevalence of AAA seems to decrease, at least screening of 65-year old males saves lives and is cost-effective. Ultrasonographic screening for AAA in risk populations fulfils the new WHO criteria for screening.

- Antimicrobial treatment to attenuate expansion of abdominal aortic aneurysm has been suggested, especially with the focus on Chlamydophila. In this systematic literature review only four randomized trials were identified. In two small studies there is an indication of an effect of roxithromycin. In conclusion, however, more studies are needed, and they must be properly sized based on power calculations as well as antimicrobially relevant. Such trials are on the way both in Europe and the US, the results being awaited with interest.

- PURPOSE: To evaluate the collective incidence of, and experience with, aortoenteric fistula after endovascular aortoiliac therapy. MATERIALS AND METHODS: A systematic literature research was performed to identify cases of aortoenteric fistulation after aortic stent-graft procedures or stent implantation. RESULTS: The review revealed 16 cases of aortoenteric fistulation after aortic stent-grafting (n = 15) or stent placement (n = 1), in 14 patients with abdominal aortic aneurysm. Six had undergone endovascular aneurysm repair because of what was considered a "hostile abdomen." The symptoms did not differ from those in patients with arterioenteric fistulation after open aortic repair. A defect in the stent-graft or its function was the predominant cause of fistulation. One fistula was diagnosed at autopsy, two patients died perioperatively, and 13 survived with in situ repair or an axillobifemoral graft, all after removal of the stent-graft or stent. However, the follow-up time was short, longer than 1 year in only five of the 13 survivors. CONCLUSIONS: Aortoenteric fistulation does occur after endovascular implantation of stents and stent-grafts. The incidence is unknown but is probably low. Follow-up time in most publications was less than 1 year, which is considered short to assess potential graft infection.
