Best graft for infra inguinal approach bypass: (A) Dacron, (B) PTFE, (C) Polyester, (D) Autologous vein
Answer is D. The great saphenous veins should be used preferentially in all bypasses, especially in those reconstructions using below-knee popliteal and small tibial aeries as the distal target vessels. PTFE grafts can be used for bypasses to above-knee popliteal aerial segments with satisfactory patency rates. Ref: Sabiston 20th edition Pgno: 1774
