Abstract: Objective To evaluate the effectiveness and safety of Rotarex thrombectomy combined with drug-coated balloon(DCB) for treatment of femoropopliteal artery in-stent restenosis(FP-ISR). Methods From June 2016 to July 2017, 32 FP ISR patients received Rotarex thrombectomy combined with DCB, which were followed up for 3 years. The primary endpoint was primary patency of the target lesion and freedom from clinically-driven target lesion revascularization (CD-TLR) at 3 years. The secondary endpoint was the rate of major adverse limb events (MALE), amputation and mortality. The primary functional endpoint was assessed by Walking Impairment Questionnaire (WIQ). Results Technical and procedural success was achieved in all 32 patients, 27(84.4%) patients completed 3 years follow-up. Mean ABI was 0.45±0.14 at baseline and 0.81±0.10 at 3 years (P<0.05). The WIQ score was 30.45±21.14 at baseline and 51.32±27.92 at 3 years (P<0.05). The Kaplan-Meier estimate of the primary patency rate at 3 years was 81.5%, freedom from CD-TLR rate at 3 years was 85.2%. Conclusion Rotarex thrombectomy combined with DCB for treatment of FP ISR is safe and effective, the medium and long-term results are satisfactory.
