aortobifemoral bypass
A surgical procedure creating a graft conduit from the aorta to both femoral arteries to bypass aortoiliac occlusive disease.
Full Definition
Aortobifemoral bypass is a major vascular surgical procedure used to treat severe aortoiliac occlusive disease by creating an alternative pathway for blood flow. The procedure involves placing a bifurcated synthetic graft (typically Dacron) from the infrarenal aorta to both common femoral arteries, bypassing diseased or occluded aortoiliac segments. This operation is considered the gold standard for treating aortoiliac occlusive disease in good-risk patients, offering excellent long-term patency rates. The procedure requires careful patient selection and perioperative management due to its significant physiological impact.
Usage
Usage note: Can be abbreviated as 'aorto-bifem' in informal surgical notes, but spell out fully in formal reports.
