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.
