Angiography in the Management of Aneurysms of the Abdominal Aorta

Abstract

The course of 190 patients with aneurysm of the abdominal aorta who underwent preoperative aortography was reviewed to determine the safety and usefulness of that procedure. There were no serious complications; minor problems occurred in only four patients and did not affect operative therapy. In 21 patients, the clinical impression of aneurysm was found to be incorrect. Surgically important findings included suprarenal extension of the aneurysm in nine patients, and demonstration of stenotic lesions in the renal arteries (37 patients) or superior mesenteric artery/celiac axis (17 patients). Helpful findings were associated aneurysms (26 patients), multiple renal arteries (28 patients), and occlusive lesions in the lower extremities or aortocranial system in 82 and eight patients respectively. Such information was found useful in planning operative procedures and minimizing operative time and blood loss. In our experience, angiography in patients with aneurysm of the abdominal aorta is both safe and informative.
