Generally, it is accepted that autogenous veins (GSVs) work better as Tibial artery bypass grafts. It could be due to the better compliance of the autogenous grafts with less intimal hyperplasia at the anastomotic junctions. Graft patency rate comes down as anastomosis goes down from the thigh to the ankle level. The photograph is showing the PTFE graft in the subcutaneous tissue and looks healthy. The surgeon feels happy to see such a result, but it is difficult to predict the future patency of the graft. Thrrombogenisity is high in such grafts, progressive vascular disease ( atherogenicity, intimal hyperplasia) make it difficult to predict patency.
