Background: Percutaneous endovascular therapy is nowadays the leading treatment option for patients with symptomatic peripheral arterial disease, but it can be complicated with distal embolization (DE). Patients and methods: We retrospectively analyzed 2054 endovascular revascularization interventions performed in patients with disabling claudication or chronic critical limb ischemia in the Catheterisation Laboratory of the Department of Vascular Diseases, University Medical Centre Ljubljana between January 2014 and December 2018. Lesions were treated by balloon angioplasty and/or stent implantation, without atherectomy. Results: The overall incidence of DE was 0.9%. DE was more frequent in females than males (1.6% vs 0.5%, p = 0.011), in the absence of antiplatelet treatment prior to intervention compared to previous antiplatelet treatment (2.1% vs 0.6%, p = 0.005) and in femoropopliteal stenting compared to angioplasty without stenting (2.2% vs 0.8%, p = 0.037). DE was successfully managed with percutaneous aspiration, in combination with angioplasty when necessary, in 84% of cases. In remaining 16% of patients, DE was managed with surgical thromboembolectomy. Conclusions: The incidence of DE during endovascular revascularization of chronic atherosclerotic lesions in lower limb arteries without use of atherectomy was low. DE was more frequent in women, in patients without prior antiplatelet treatment and in femoropopliteal stenting. The majority of DE was successfully managed percutaneously.
