Aortobifemoral bypass graft is an open vascular operation used to restore blood flow to both legs when the lower abdominal aorta and/or iliac arteries are severely narrowed or blocked, most often from atherosclerotic peripheral arterial disease.

What is done

A synthetic Y-shaped graft is sewn:
  • Proximally to the abdominal aorta above the blockage
  • Distally to the right and left femoral arteries in the groins
It creates a new route for blood around the diseased aortoiliac arteries.

Typical indications

  • Disabling buttock, thigh, or calf claudication despite medical therapy and exercise
  • Critical limb-threatening ischemia: rest pain, non-healing ulcers, gangrene
  • Extensive bilateral aortoiliac occlusive disease when angioplasty/stenting is unsuitable or has failed
It is considered a durable standard open reconstruction for extensive aortoiliac disease. Schwartz reports approximately 70-80% patency at 10 years in appropriate patients, with operative risk strongly influenced by coexisting cardiac, carotid, renal, and other vascular disease. Schwartz's Principles of Surgery, 11e, p. 971. Miller describes it as the gold-standard anatomic reconstruction for aortoiliac occlusive disease, while extra-anatomic bypass is generally reserved for patients at excessive operative risk, infection, or failed prior reconstruction. Miller's Anesthesia, 10e, p. 7940.

Main complications

  • Bleeding, wound or graft infection
  • Graft thrombosis or recurrent blockage
  • Heart attack, stroke, kidney injury, respiratory complications
  • Bowel ischemia or injury, rarely
  • Groin lymph leak
  • Sexual dysfunction in some men due to nerve injury
  • Limb ischemia, amputation, or death in severe cases
The Society for Vascular Surgery overview lists graft blockage/infection, bleeding, wound complications, myocardial infarction, stroke, reoperation, limb loss, and death among potential risks.

Recovery

Postoperatively, patients are monitored closely, sometimes initially in ICU or a high-dependency setting. Hospital stay is often about 4-7 days, although this varies with health status and complications. Walking is restarted early; heavy lifting is restricted until abdominal and groin wounds heal. Long-term care includes smoking cessation, antiplatelet and lipid-lowering therapy when indicated, diabetes/BP control, and graft surveillance. MedlinePlus patient guidance provides a practical summary of perioperative care and recovery.
Urgent assessment is needed after surgery for a suddenly cold/painful leg, loss of pulses, new wound redness or discharge, fever, chest pain, shortness of breath, or severe abdominal pain.
