Long-term Results of the Combined Use of Rotational Atherectomy and Drug-Coated Balloon in Isolated Total Occlusion of the Superficial Femoral Artery

Abstract

Aim: In this study, we aimed to evaluate the long-term results of combined treatment with rotational atherectomy (RA) and drug-coated balloon (DCB) in isolated total occlusion of the superficial femoral artery (SFA). Materials and Methods: The retrospective study was conducted between February 2016 and January 2018 and included a total of 23 limbs of 20 patients with isolated total occlusion of the SFA. Patient data on demographic and clinical characteristics were obtained from the hospital records. The stage of the disease was classified according to the Rutherford classifi- cation. The ankle–brachial index was measured pre- and postoperatively. Results: Of the patients, 19 (95%) were male and one (5%) was female. The mean patient age was 67.40±7.50 (49–77) years. According to the preoperative Rutherford classification, there were 4 (17.40%) limbs with stage 5 disease, 8 (34.80%) limbs with stage 4 disease, and 11 (47.80%) limbs with stage 3 disease. The rates of one- and two-year freedom from target lesion revascularization were 82.61% and 69.57%, respectively. Discussion and Conclusion: Our study results showed that combined treatment with RA and DCB was an effective method in SFA lesions with a high calcified plaque burden, providing high rates of primary patency and freedom from target lesion revascularization as well as low rates of complication.
