One-Year Outcomes of Femoropopliteal Chronic Total Occlusions Treated With Percutaneous Provisional Approach: A Single Center Experience (Percutaneous Treatment of Femoropopliteal CTO)

Abstract

Objective: The aim of the present study was to evaluate the results of percutaneous treated femoropopliteal chronic total occlu-sions (CTOs).Methods: A total of 204 limbs (167 patients) that were treated with drug-coated balloon angioplasty and/or self-expandable stent implantation between January 2015 and December 2017 were assessed. Immediate and follow-up features were expressed with frequency tables, and Kaplan–Meier analysis was calculated for primary, primary-assisted, and secondary patency rates.Results: In 202 (99%) cases, optimal targeted success was achieved. Death, arterial rupture requiring surgery, and myocardial in-farction were not observed in the hospital period. In only 6 (3%) cases, an entry site hematoma developed but recovered without any intervention. Restenosis in 22 patients (5 in the first 6 months and 17 in the second 6 months) and reocclusion in 8 patients (2 in the first 6 months and 6 in the second 6 months) were observed in a 1-year follow-up. Primary, primary-assisted, and secondary patency rates were found to be 85.1%, 96%, and 98%, respectively, at the end of the first year.Conclusion: Percutaneous revascularization of femoropopliteal CTOs appears to be safe and effective.
