Discussion and management of late failures in reconstructive procedures involving the abdominal aorta.

Review of fifty-eight late failures of 326 procedures performed for revascularization of the abdominal aorta over the past six years showed a low overall operative mortality of 9 per cent. Secondary vascular procedures directed at the aorta itself or at its graft substitute proved more effective in relieving symptoms and restoring flow than did secondary procedures directed at more distal problems in the lower extremities. The aortofemoral graft in conjunction with profundaplasty proved to be the most effective means of restoring flow to the lower extermity after graft occlusion in a previous aortoiliac or aortofemoral graft.
