Intermediate-term Outcomes after Endovascular Treatment of Atherosclerotic Femoropopliteal Occlusive Lesions

Abstract

Background: Endovascular treatment is considered first-line therapy for most femoropopliteal occlusive disease. This study evaluated the Intermediate-term outcomes of endovascular treatment on atherosclerotic femoropopliteal occlusive lesions. Materials and methods: From among the 675 endovascular procedures on lower extremity arteries in our database, we retrospectively selected a consecutive series of 286 procedures on femoropopliteal lesions with or without other target arteries on 262 limbs in 215 patients from 2010 to 2017. The Target Lesion Revascularization (TLR) free rate, limb salvage and patients’ survival were investigated. Results: Mean age was 71.0 ± 10.4 years, and mean follow-up duration was 21.8 ± 18.2 (range, 0.1 - 82.9) months. During follow-up, repeated procedures were needed in 30 limbs (11.5%). 72 patients (33.5%) had died because of medical conditions unrelated to angioplasty. The TLR free rate at 1 year, 3 years, and 5 years were 91.3%, 84.4%, and 68.9%, respectively. Amputation-free survival at 1 year, 3 years, and 5 years were 81.4%, 55.0%, and 41.0%, respectively. Conclusions: Endovascular treatment on atherosclerotic femoropopliteal lesions showed acceptable TLR free rate in intermediate-term. However, the amputation free survival rate was relatively low mainly due to poor survival.
