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

• To investigate the risk of procedure-related major amputation attributable to revascularization for intermittent claudication (IC) in a population-based observational cohort study.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. For the final analysis, complete medical records of all patients with IC, having ipsilateral amputation after the revascularisation procedure, were reviewed. Patients wrongly classified as having IC were excluded. Ipsilateral amputations within one year of the revascularisation were defined as procedure related.Altogether, 5 860 patients revascularised for IC were identified of whom 109 were registered to have undergone a post-operative ipsilateral lower limb amputation during a median follow up of 3.9 years (standard deviation 1.5y). Seventeen were duplicate registrations and 51 were patients with chronic limb threatening ischaemia, misclassified as IC in the registry. One patient had not undergone any revascularisation, one was revascularised for a popliteal artery aneurysm, one was revascularised for acute limb ischaemia, one had a minor amputation only, and one patient was not amputated at all. Twenty-seven were amputated more than one year after the procedure. Thus, the major amputation rate within one year of revascularisation for IC was 0.2% (n=9/5 860).Revascularisation for IC in a contemporary setting confers a low but existing risk of procedure related major amputation within the first post-procedural year.
