infrainguinal bypass

Surgical revascularization procedure creating a conduit around diseased arteries below the inguinal ligament.

Full Definition

Infrainguinal bypass refers to surgical revascularization procedures that create alternate pathways for blood flow around diseased arteries located below the inguinal ligament, typically involving the femoral, popliteal, and tibial vessels. Common configurations include femoropopliteal and femorotibial bypasses using autogenous vein grafts, synthetic grafts, or composite conduits. These procedures are performed for critical limb ischemia or severe claudication when endovascular interventions are not feasible or have failed. Graft patency and limb salvage rates vary based on conduit type, target vessel, and patient factors.

Usage

Usage note: Specify graft material and anatomical configuration in surgical documentation.

In Context

  • "The patient underwent infrainguinal bypass with reversed saphenous vein graft from femoral to below-knee popliteal artery." — Operative report
  • "Five-year patency rates for infrainguinal bypass are superior with autogenous vein compared to synthetic grafts." — Clinical outcomes study
