Endovascular treatment versus femoropopliteal bypass surgery for TASC II type C lesions of the superficial femoral artery

Objectives: In this study, we aimed to compare the outcomes of endovascular treatment (ET) and femoropopliteal artery bypass (FPB) in patients with Trans-Atlantic Inter-Society Consensus (TASC) II type C femoropopliteal lesions. Patients and methods: A total of 149 patients with symptomatic TASC II type C femoropopliteal lesions who underwent invasive treatment between January 2012 and January 2017 were retrospectively analyzed. The patients were divided into two groups as the ET group (n=46; 34 males, 12 females; mean age: 64.3±10.3 years) and the FPB group (n=103; 82 males, 21 females; mean age: 62.9±8.2 years). Primary and secondary patency rates at 6, 12, and 24 months were evaluated. Results: The primary success rates for ET and FPB were 100%. Primary patency at 6, 12, and 24 months were 93.5%, 89.0%, 69.5%, respectively for ET and 86.4%, 81.5%, 72.8%, respectively for FPB (p>0.05). Secondary patency rates at 6, 12, and 24 months were 97.8%, 93.5%, %84.8, respectively for ET and 96.1%, 90.3%, 79.6%, respectively for FPB group (p=0.41). The length of hospital stay was significantly longer in the FPB group (p<0.001). The cost of treatment was significantly higher in the FBP group (p=0.02). Conclusion: In TASC II type C patients, ET is a safe therapeutic option with lower in-hospital stay and treatment expenses and similar primary and secondary patency rates to FPB.
