title: Reoperative approaches to failed procedures confined entirely to the abdominal aorta.
abstract: Options do exist when the vascular surgeon is faced with failed procedures confined to the abdominal aorta. Knowledge of the various techniques outlined previously allows an orderly and minimal-risk approach in these patients. Use of the original graft is often the first choice to revascularize ischemic lower extremities in low-risk patients. Extra-anatomic bypasses are generally reserved for high-risk patients. The exception is hepatorenal and splenorenal bypasses that are the revascularization method of choice in most patients with failed unilateral aortorenal bypasses.
