Long-term clinical effectiveness of a drug-coated balloon for in-stent restenosis in Femoropopliteal lesions
BACKGROUND: The short-term efficacy of paclitaxel-coated balloons (PCBs) has been established in femoropopliteal in-stent restenosis (ISR) lesions. The aim of this study was to compare 5-year clinical outcomes of patients with femoropopliteal ISR lesions undergoing percutaneous transluminal angiopla...

Sumario: | BACKGROUND: The short-term efficacy of paclitaxel-coated balloons (PCBs) has been established in femoropopliteal in-stent restenosis (ISR) lesions. The aim of this study was to compare 5-year clinical outcomes of patients with femoropopliteal ISR lesions undergoing percutaneous transluminal angioplasty (PTA) with and without PCB. METHODS: After 1:1 propensity score matching, we extracted 50 patients with femoropopliteal ISR lesions undergoing PTA with (n = 25) and without (n = 25) IN.PACT PCB (Medtronic, Minneapolis, MN) from 106 consecutive ISR patients treated in our hospital between 2009 and 2015. We compared the 5-year outcomes between PCB and non-PCB groups. The primary endpoint was the cumulative 5-year incidence of recurrent restenosis. All-cause mortality, target lesion revascularization (TLR) and unplanned major amputation were also assessed. RESULTS: The primary patency after PCB treatment at 5 years was significantly higher than the patency after non-PCB treatment (65.7% vs. 18.7%; hazard ratio [HR]: 6.11; 95% confidence intervals [CI]: 2.57–16.82; p < 0.001), as well as freedom from TLR (77.6% vs. 53.8%; HR: 3.55; 95% CI: 1.21–12.83; p = 0.020). All-cause mortality and unplanned major amputation rates did not significantly differ between the two groups. The Cox proportional hazard multivariate analysis showed that PCB was independently associated with preventing recurrent restenosis (HR: 0.17; 95% CI: 0.06–0.41; p < 0.001). CONCLUSIONS: At 5 years, patients with femoropopliteal ISR lesions undergoing PCB treatment showed significantly lower recurrent restenosis than those that underwent non-PCB treatment.
