title: Value of angiography in the management of abdominal aortic aneurysm.
abstract: The value of angiography in the management of abdominal aortic aneurysms (AAA) was assessed in 100 consecutive patients with AAA. Angiographic information influenced management decisons and/or surgery performance in 75: In 23 patients at high risk for surgery because of associated medical problems, it helped in deferring surgery; in 52 patients it resulted in a change of operation from a standard aneurysm resection with conventional grafting to a more conservative procedure (three patients), more extensive grafting (45 patients) and/or the addition of other vascular reconstructions (32 patients). Angiography is considered an integral step in the routine preoperative workup of AAA and is particularly valuable for the determination of important anatomic details about the aneurysm (upper and lower extensions, relation to the renal arteries), the detection of associated vascular disease (of renal, visceral, pelvic and peripheral arteries), and the demonstration of aberrant renal arteries and collateral visceral circulation. Catheter techniques are considered most suitable and safe for examination of AAA.
