ABSTRACT
Extraanatomic bypass grafts represent an important alternative reconstructive technique to conventional bypass methods in certain clinical situations. Revascularization of the brain, ischemic organs, or ischemic upper and lower extremities is traditionally carried out by a direct anatomic approach to the diseased vessels, relieving the occlusive process by endarterectomy, bypass grafting, or a combination of both. Alternative approaches to reconstruction are necessary when a conventional approach would carry too great a risk because of the poor health of the patient, the presence of infection, or other anatomic factors precluding direct exposure to the diseased vessels.
