Computed tomography of the postoperative abdominal aorta.

Computed tomography (CT) of the abdomen was performed on 46 patients who had undergone graft replacement of abdominal aortic aneurysms. Twelve postoperative complications were found in nine patients. They included hemorrhage, infection, anastomotic pseudoaneurysms, major vessel occlusion, postoperative pancreatitis, and others. The varied appearance of the normal postoperative graft is also presented. It is concluded that CT is a rapid, sensitive, and noninvasive method for detecting or excluding postoperative complications of abdominal aortic surgery.
