When bypassing to a distal foot artery from a below-knee popliteal segment, using the patient's own vein as the conduit gives the best long-term openness in small, distal vessels. The reversed greater saphenous vein fits this need well: harvest the vein, invert it so the valves are oriented with the arterial flow, and connect from the popliteal region down to the dorsalis pedis. This setup prevents valve blockage without needing a valvulotome, and the vein’s natural compatibility with arterial pressure and flow preserves patency better in distal bypasses than synthetic grafts. Synthetic PTFE grafts, while useful in some situations, tend to occlude more often in tibial/pedal targets due to smaller caliber and hostile runoff. Radial artery grafts can work but are less ideal here because of smaller diameter and potential donor-site issues.
