Abstract:
Objective To compare the safety and efficacy of directional atherectomy with anti-restenosis therapy(DAART,drug-coated balloon)versus conventional balloon angioplasty(bare-metal stent,BMS)in elderly patients with femoropopliteal artery disease.Methods A retrospec-tive cohort study was conducted on 116 elderly patients undergoing endovascular intervention due to femoropopliteal artery disease in our hospital between May 2016 and September 2019,divided into DAART group(57 cases)and BMS group(59 cases).Results No statistical differences were observed between the DAART and BMS groups in terms of age,risk factors,distribution of Ruth-erford classification,lesion length,lesion type,lesion location,Global Limb Anatomic Staging Sys-tem grade,infra-popliteal runoff status,or preoperative ankle-brachial index(P＞0.05).However,the BMS group had significantly larger proportion of chronic limb-threatening ischemia than the other group(P＜0.05).Both groups achieved a 100％success rate of surgery.The DAART group obtained obviously higher primary patency rates at 1 and 2 years than the BMS group(90.4％vs 75.0％,76.3％vs 57.3％;P＜0.045).There were no significant differences in the rate of freedom from target lesion revascularization at 1 and 2 years between the two group(96.1％vs 88.8％,91.6％vs 77.7％;P＞0.05).In 2 years of follow-up,the incidence of major adverse events was 10.0％(5 cases)in the DAART group and 20.8％(12 cases)in the BMS group,but no obvious difference(P＞0.05).Conclusion DAART demonstrates superior mid-term efficacy than BMS in treating femoropopliteal artery disease in elderly patients.However,comprehensive preoperative assessment is essential to optimize individualized treatment strategies for this population.
