The aim of this study was to compare technical success, patency rates and clinical outcomes of vein bypass (VBP) with angioplasty and nitinol stents (NS) in femoropopliteal Trans-Atlantic Intersociety Consensus (TASC) II C and D lesions. Summary Background Data: Guidelines widely recommend an endovas-cular-first strategy for long femoropopliteal lesions without sufficient data comparing it with vein bypass surgery. Methods: A single-center prospective, randomized controlled trial (RCT) was performed, after approval of the local ethics committee, with technical success, primary and secondary patency as primary endpoints. Secondary endpoints were limb salvage, survival, complications, and clinical improvement. Results: Between 2016 and 2020, 218 limbs (109 per group) in 209 patients were included. Baseline and lesion characteristics were similar in both groups with a mean lesion length of 268 mm. The indication for treatment was chronic limb threatening ischemia in 53% of limbs in both groups. Technical success was feasible in 88% in the stent group. During a 4-year follow-up, primary patency, freedom from target lesion revascularizations, limb salvage, survival and complications showed no significant differences between the groups. At 48 months secondary patency for the bypass group was 73% versus 50% in the stent group ( P = 0.021). Clinical improvement was significantly superior in the bypass group with 52% versus 19% reaching a Rutherford 0 category ( P 〈 0.001). Conclusions: This is the largest RCT comparing angioplasty with NS and vein bypass in femoropopliteal TASC II C and D lesions and the first to report 4-year results. The data underline the feasibility of endovascular treatment in long lesions but also emphasize the advantages of VBP.
