FEMOROPOPLITEAL BYPASS GRAFT
Indication: Superficial femoral artery (SFA) occlusion causing rest pain, tissue loss, or incapacitating claudication failing conservative management. Above-knee popliteal: vein or PTFE graft with comparable early results. Below-knee popliteal: autologous vein strongly preferred (inferior patency with prosthetic graft below the knee).
Patient Position: Supine, ipsilateral leg slightly flexed and externally rotated.
Anaesthesia: General, regional, or local with sedation.
