infrainguinal bypass
Surgical bypass procedures performed below the inguinal ligament to treat lower extremity arterial occlusive disease.
Full Definition
Infrainguinal bypass encompasses surgical revascularization procedures performed distal to the inguinal ligament, primarily targeting the superficial femoral, popliteal, and tibial arteries. These procedures include femoral-popliteal, femoral-tibial, and popliteal-tibial bypasses, typically performed for severe claudication, rest pain, or tissue loss. Conduit selection (autologous vein versus synthetic graft) significantly impacts long-term patency, particularly for below-knee targets.
Usage
Usage note: Specify exact bypass targets when possible; avoid confusion with 'infragenicular' (below the knee).
