Abstract

Objectives: To compare drug-coated balloon (DCB) and bare metal stent (BMS) for primary lesions in femoropopliteal artery disease in Chinese population and to make subgroup analysis between the groups. Methods: Patients with primary lesions who underwent BMS or DCB treatment of a single tertiary vascular center were included and followed up for 24 months. Clinical and anatomic status were reported using the criteria recommended by the Society for Vascular Surgery. The primary endpoint included primary patency, clinically target limb revascularization, composite safety endpoint and all-cause death over 24 months assessed by Kaplan-Meier. Secondary endpoints included technical success rate and stent-related complications. Results: A total of 284 patients with 324 limbs were pooled into analysis and most of the baseline characteristics did not show significant difference. A total of 74 in BMS group and 71 in DCB group were claudicants while 83 in BMS group and 56 in DCB group suffered from chronic limb threatening ischemia (CLTI). The mean cumulative lesion length was 18.7 ± 9.8cm in BMS group while 17.2 ± 10.3cm in DCB group. Kaplan-Meier estimates of primary patency were 75.3% and 80.9% for BMS and DCB groups at 12 months while decreased to 63.9% and 70.2% at 24 months (log-rank P = 0.167), respectively. Freedom from clinically driven target limb revascularization was 86.8% and 92.7% for BMS and DCB groups at 12 months while dropped to 82.5% and 85.9% at 24 months (log-rank P = 0.342). Estimates of primary patency between BMS and DCB group did not show significant difference on lesions with poor runoff (58.8% vs. 67.3%, log-rank P = 0.127), severe calcification (64.5% vs. 69.4%, log-rank P = 0.525) and popliteal artery involvement (59.3% vs. 60.3%, log-rank P = 0.695) at 24 months. The overall survival (92.6% for BMS, 90.3% for DCB, log-rank P = 0.391) and freedom from composite safety endpoint (79.3% for BMS, 79.2% for DCB, log-rank P = 0.941) showed no significant difference at 24 months. Conclusions: Over the 24 month follow-up, BMS and DCB showed equivalent efficacy and safety outcomes for primary femoropopliteal artery disease, which indicated the reduction of permanent metallic implant insertion might be possible.
