title: Leg ischemia following surgery for abdominal aortic aneurysm.
abstract: Resection of an abdominal aortic aneurysm was associated with intraoperative or postoperative leg ischemia in seven of 100 consecutive survivors of this procedure. Distal embolization of thrombus and debris is the apparent cause in the majority of cases (six). One case of stenosis at a graft-to-vessel anastomosis was identified. Early (intraoperative) thromboembolectomy averted tissue loss in four cases. The role of concurrent lumbar sympathectomy in ameliorating ischemic tissue loss is evaluated. Postaneurysmectomy leg ischemia may accompany other serious complications, particularly hypotension and renal failure.
