Complications following the treatment of abdominal aortic aneurysms.

The complications following the surgical treatment of 328 cases of abdominal aortic aneurysm are reported. In some cases such complications are predictable and their knowledge is useful to reduce the operative mortality. Cardiac and renal complications were more frequent in emergency, while surgical complications were mostly observed in patients with large aneurysms involving the iliac arteries. Duodenal lesions were caused in patients affected by inflammatory aneurysms. The late complications observed were: ureteral stenosis, infections, pseudoaneurysms and occlusion of a branch of the bifurcated graft.
