Comparison of Magnetic Resonance Angiography and Digital Subtraction Angiography for the Assessment of Infrapopliteal Arterial Occlusive Lesions, Based on the TASC II Classification Criteria.

This paper aimed to study the agreement and repeatability, both intra- and interobserver, of infrapopliteal lesion assessment with magnetic resonance angiography (MRA), using the TransAtlantic Inter-Society Consensus (TASC) II criteria, with perioperative digital subtraction angiography (DSA) as a reference. Sixty-eight patients with an MRA preceding an endovascular infrapopliteal revascularization were included. Preoperative MRAs and perioperative DSAs were evaluated in random order by three independent observers using the TASC II classification.

Low Risk of Procedure Related Major Amputation Following Revascularisation for Intermittent Claudication: A Population Based Study.

Objective: To investigate the risk of procedure-related major amputation attributable to revascularization for intermittent claudication (IC) in a population-based observational cohort study.

Methods: All patients who underwent open or endovascular lower limb revascularisation for IC in Sweden between 12 May 2008 and 31 December 2012 were identified from the Swedish National Quality Registry for Vascular Surgery (Swedvasc) and data on above ankle amputations were extracted from the National Patient Registry. Any uncertainty regarding amputation level and laterality was resolved by reviewing medical charts.

Impact of Preoperative Symptoms and Revascularized Arterial Segment in Patients With Chronic Limb-Threatening Ischemia.

Background: Little is known about the relative impact of the preoperative symptoms rest pain and tissue loss, and of the arterial segment revascularized, on amputation rate and mortality in patients with chronic limb-threatening ischemia (CLTI). We wanted to investigate this topic further.

Method: This population-based observational cohort study involved 10 419 patients revascularized for CLTI in Sweden, 2008 to 2013.

Editor's Choice - Impact of Comorbidity, Medication, and Gender on Amputation Rate Following Revascularisation for Chronic Limb Threatening Ischaemia.

Objective/background: Chronic limb threatening ischaemia (CLTI) has a high risk of amputation and mortality. Increased knowledge on how sex, comorbidities, and medication influence these outcomes after revascularisation may help optimise results and patient selection.

Methods: This population based observational cohort study included all individuals revascularised for CLTI in Sweden during a five year period (10,617 patients in total).
