The aim of this study was to investigate outcomes for lower limb revascularisation for limb salvage within the National Health Service (NHS) in England.

This was a retrospective observational study of administrative data. Data were extracted from the Hospital Episodes Statistics database for England. Data were included for a seven year period (1 April 2011-31 March 2018 inclusive) for all patients aged≥18 years receiving surgery for peripheral arterial occlusive disease. Data were extracted for patient age, sex and frailty level, the NHS trusts undertaking the procedure, the technique used (angioplasty, bypass, endarterectomy, or hybrid), the mode of admission (elective or emergency), the surgical speciality, the financial year of admission, length of hospital stay during the procedure, subsequent emergency re-admission, revascularisation procedures within 30 days and subsequent amputation and mortality within one year and within five years. The primary outcome was one year amputation free survival. For a definitive data.
Outcomes were generally better for angioplasty than for bypass surgery for lower limb revascularisation for both diabetic and non-diabetic patients. The findings should be interpreted with caution given the likely different clinical presentations of those selected for each procedure. Future clinical trials may provide more definitive data.
The aim of this study was to measure the incidence of post endovascular aneurysm sealing (EVAS) abdominal aortic aneurysm (AAA) growth, and its association with stent migration, in a cohort of patients with differing compliance to old and new Instructions For Use (IFU).

A retrospective single centre study was conducted to review the computed tomography (CT) and clinical data of elective, infrarenal EVAS cases, performed as a primary intervention, between December 2013 and March 2018. All included patients had a baseline post-operative CT scan at one month and at least one year follow up. The primary outcome measure was the incidence of AAA growth and its association with stent migration. AAA growth was defined as a ≥5% increase in aortic volume between the lowermost renal artery and the aortic bifurcation post EVAS at any time during follow up, in comparison to the baseline CT scan. Migration was defined according to the ESVS guidelines, as > 10mm downward movement of either Nellix stent frame in the pis IFU compliant. AAA growth by volume is associated with stent migration. Clinicians should continue close surveillance post EVAS, regardless of whether patients are treated within IFU.
Endovascular revascularisation has become a standard approach for below knee lesions and paclitaxel coated devices have been widely used in patients with chronic limb threatening ischaemia. A recent meta-analysis reported higher mortality in paclitaxel coated devices compared with uncoated devices in femoropopliteal lesions. This study aimed to determine long term outcomes in below the knee interventions using paclitaxel coated devices in routine vascular care using a large and contemporary cohort.

A large cohort was created using all inclusive health insurance claims data of patients covered by the second largest insurance fund in Germany. The cohort included patients with index revascularisation of arteries below the knee performed from 1 January 2010, to 31 December 2018. Only patients with first paclitaxel coated device exposure were included. The study cohort was stratified into balloon vs. stent treatment and patients with paclitaxel coated devices were matched with uncoated devices using propensity matched cohort, reduced long term all cause mortality, reduced rates of amputation or death and cardiovascular event or death were observed at five years after the use of paclitaxel coated devices when compared with uncoated devices for the treatment of chronic limb threatening ischaemia.
Popliteal artery aneurysm (PAA) is the second most common arterial aneurysm. Vascunet is an international collaboration of vascular registries. The aim was to study treatment and outcomes.

This was a retrospective analysis of prospectively registered population based data. Fourteen countries contributed data (Australia, Denmark, Finland, France, Hungary, Iceland, Italy, Malta, New Zealand, Norway, Portugal, Serbia, Sweden, and Switzerland).

During 2012-2018, data from 10764 PAA repairs were included. Mean values with between countries ranges in parenthesis are given. The incidence was 10.4 cases/million inhabitants/year (2.4-19.3). The mean age was 71.3 years (66.8-75.3). Most patients, 93.3%, were men and 40.0% were active smokers. The operations were elective in 73.2% (60.0%-85.7%). The mean pre-operative PAA diameter was 32.1 mm (27.3-38.3 mm). Open surgery dominated in both elective (79.5%) and acute (83.2%) cases. Selleck Bexotegrast A medial surgical approach was used in 77.7%, and posterior in 22.3%. Vein grafts weron these results.
Patients presenting with acute ischaemia had high risk of amputation. The frequent use of endovascular repair and prosthetic grafts should be reconsidered based on these results.
Arteriovenous grafts (AVGs) are the second best option for haemodialysis access when native arteriovenous fistulae placement is not possible, because they have a lower patency owing to neointimal hyperplasia at the venous anastomosis. This review aimed to evaluate the effect of geometric graft modification to the graft-vein interface on AVG patency.

The MEDLINE and Embase (OvidSP) databases were systematically searched for relevant studies analysing the effect of geometrically modified AVGs on graft patency and stenosis formation (last search July 2019).

Data regarding AVG type, patency, and graft outlet stenosis was extracted for further evaluation. Data were pooled in a random effects model to estimate the relative risk of graft occlusion within one year. Follow up, number of patients, and relevant patient characteristics were extracted for the quality assessment of the included studies using Newcastle-Ottawa Scale and Cochrane Risk of Bias Tool. The quality of the evidence was determined according to the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) system.
