Prosthetic Conduits have Worse Outcomes compared to Great Saphenous Vein Conduits in Femoropopliteal and Infrapopliteal Bypass in Patients with Chronic Limb Threatening Ischemia

Single segment great saphenous vein (SSGSV) has traditionally been considered the gold standard conduit for infrainguinal bypass. There are data supporting similar outcomes with prosthetic femoral-popliteal bypass. Moreover, some have advocated for prosthetic conduit for femoral tibial bypass when GSV is inadequate or unavailable. We sought to evaluate long-term outcomes of infrainguinal bypass based on conduit type for treating chronic limb threatening ischemia (CLTI).
