Should aortography be used routinely in the elective management of abdominal aortic aneurysm?
Until recently aortography was performed routinely for elective abdominal aortic aneurysm at our institution. A death resulting from this procedure prompted us to evaluate this policy by a retrospective study of 105 elective aneurysm patients. These studies identified 21 renal artery stenoses, 2 renal artery aneurysms, 2 cases of multiple renal arteries, 8 celiac stenoses, 6 superior mesenteric artery stenoses or occlusions, and a number of peripheral occlusive processes and associated iliac aneurysms. However, the impact of these findings on surgical management was limited to six renal artery reconstructions: one for reimplantation of a renal artery arising from the aneurysm, one for serious hypertension, and four in normotensive patients with severe arterial stenosis. No celiac or mesenteric reconstructions were undertaken, and no visceral complications ensured. In only one patient, the one with renal artery reimplantation, was the angiographic information unsuspected and significant for operative management. This did not appear to justify the risk and expense involved in routine preoperative aortography.
