Results of subintimal and endoluminal angioplasty in chronic total occlusion of the superficial femoral artery

Abstract

Introduction: Endovascular revascularization is key in the management of chronic lower limb ischemia. Objective: To describe the outcomes of subintimal angioplasty in the treatment of superficial femoral artery chronic total occlusion. Materials and methods: Observational, descriptive, cross-sectional, and prospective study. The study population consisted of patients diagnosed with chronic total occlusion of the superficial femoral artery, treated at a referral center in the Autonomous City of Buenos Aires during the period from January 2022 to December 2023. Results: 42 patients were selected, median age 68 years, 16 women (38.1%), with a Leriche-Fontaine grade III in 32 patients (76.2%), and IV in 10 (23.8%), and an occlusion length of more than 10 cm in the entire sample. Pre-procedure ABI was less than 0.9 in all cases, and greater than 0.9 post-procedure (p<.001). Intra-procedural adverse events occurred in 28 patients (66.7%) and only three required reinterventions Conclusion: Subintimal and endoluminal angioplasty represent viable and effective revascularization techniques in the treatment of patients with CLI in the femoral artery.
