Bypass surgery in limb salvage: polytetrafluoroethylene prosthetic bypass

Abstract

Polytetrafluoroethylene (PTFE) grafts have proven to be an adequate alternative conduit for peripheral bypass operations. Whether or not one uses PTFE depends on several factors: surgeon preference, individual patient circumstances, or when autologous greater saphenous vein is not available or adequate. These conventional grafts have evolved and undergone modification. The intraluminal surface has been coated with carbon or bonded with heparin. The structure of grafts has been modified with the creation of a hood or cuff, with the incorporation of a stent-graft segment for a sutureless anastomosis, or the fusion of PTFE with an outer polyester layer to minimize suture hole bleeding. This evolution intends to limit graft thrombogenicity, ameliorate the formation of intimal hyperplasia, decrease complications, and improve overall graft patency.

Keywords: autologous greater saphenous vein (AGSV); critical limb ischemia; graft patency; heparin-bonded PTFE; peripheral arterial bypass graft; polytetrafluoroethylene (PTFE) graft.
