ABSTRACT
PURPOSE: Describe outcomes after endovascular intervention of TransAtlantic Inter-Society Consensus C and D femoro-popliteal disease. MATERIALS AND METHODS: Retrospective cohort study. Patient demographics, ankle-brachial indices, and lesion details were analyzed from a prospectively maintained database. In all, 980 limbs treated with percutaneous transluminal angioplasty±stenting of the femoro-popliteal segment between 2005 and 2012 were reviewed. Seventy-six patients representing 83 limbs with de novo TransAtlantic Inter-Society Consensus C and D lesions measuring ≥15 cm continuously were identified (mean age 71.3±12.1 years, 62% male). RESULTS: Twenty-five (30.1%) limbs were treated for severe claudication and 58 (69.9%) for critical limb ischemia. The mean pre-procedural ankle-brachial index was 0.47±0.19. The mean lesion length was 22.9±4.82 cm. Seventy patients representing 77 limbs were available for a mean follow-up length of 19.5 months (range 0-79). The mean post-procedural ankle-brachial index was 0.71±0.28. Primary, assisted-primary, and secondary patency rates were 68.1%, 72.7%, and 83.3% at 6 months, 55.3%, 63.6%, and 58.3% at 12 months, and 38.2%, unavailable, and 10.4% at 24 months, respectively. CONCLUSIONS: Angioplasty-first strategy for TransAtlantic Inter-Society Consensus C and D lesions of the femoro-popliteal artery can be safely performed. However, patency drastically decreases after 12 months suggesting further improvements are required to achieve longer-term clinical benefit.
