RESUMO
PURPOSE: The previously reported 6-month angiographic and 12-month clinical outcomes of the CONSEQUENT trial demonstrated the safety and efficacy of a novel paclitaxel-resveratrol-coated balloon for the treatment of lesions in the femoropopliteal segment. The purpose of this report is to present the 2-year results including a cost-benefit analysis for Germany. MATERIALS AND METHODS: Patients with symptomatic peripheral artery occlusive disease in femoropopliteal lesions were randomized either to drug-coated balloon (DCB, n = 78) or plain old balloon angioplasty (POBA, n = 75). As secondary endpoints, the 2-year clinical results consisting of target lesion revascularization (TLR), patency and increase in walking distance were recorded. Based on the Kaplan-Meier analyses for TLR and other adverse events, a cost-benefit analysis was conducted for the German DRG system. RESULTS: There were no additional TLRs in both groups between 14 and 24 months so that the corresponding rates remained significantly different between the treatment groups (DCB: 19.1 vs. POBA 40.6%, p = 0.007). At 2 years, the patency rate was significantly higher in the DCB group (72.3 vs. 48.4%, p = 0.006). The walking distance increase was also significantly higher after DCB angioplasty (172 ± 103 vs. 52 ± 136 m, p = 0.001). We estimated 2-year cost savings of 1111.97 per patient treated with DCB instead of POBA. CONCLUSIONS: The use of paclitaxel-resveratrol matrix-coated peripheral balloons compared to POBA was associated with a significantly reduced TLR rate, superior patency and substantial cost savings at 2 years.
