Risk factors of incident acute limb ischemia after contemporary femoropopliteal endovascular revascularization from a multicenter registry: A retrospective observational study.

ABSTRACT:

Purpose

To investigate the incidence of acute limb ischemia (ALI) among patients with femoropopliteal (FP) lesions treated with contemporary endovascular therapy (EVT) and to identify risk factors for ALI after FP-EVT.

Methods

In this retrospective multicenter registry, we analyzed patients with lower extremity artery disease having FP lesions who underwent EVT between 2017 and 2021. We investigated the incident ALI related to the index EVT and its risk factors. We also assessed the prognosis after the incident ALI.

Results

During a median follow-up of 35.3 months, incident ALI was observed in 72 of 3102 patients (2.3%). The Rutherford classification I/IIa/IIb/III was 50.0%, 30.5%, 18.1%, and 1.4%, respectively. Variables independently associated with the incident ALI
