    Abstract:
    The purpose of this article is to determine the role of intravenous digital subtraction angiography (IV-DSA) as an adjunct to computed tomography (CT) in the preoperative evaluation of patients with abdominal aortic aneurysm. Sixty-six patients underwent IV-DSA as well as CT during a 2-year period. Sixty-four of the 66 patients underwent abdominal aortic aneurysm repair. The results of the 66 patients were analyzed to assess what additional information was obtained by IV-DSA concerning aneurysm size, vascular anomalies, visceral arterial anatomy, associated aneurysmal disease, and iliofemoral and distal occlusive disease. On the basis of this study, it is suggested that IV-DSA has a limited role in the preoperative evaluation of patients with abdominal aortic aneurysm.
