A single-stage operation for abdominal aortic aneurysm with concomitant colorectal carcinoma.

Abstract

The coexistence of abdominal aortic aneurysm (AAA) and colorectal carcinoma needs special operative consideration. A single-stage operation for concomitant AAA and colorectal carcinoma has been thought to increase the risk of vascular prosthetic graft infection. We report two patients who received a single-stage operation for AAA and colorectal carcinoma. The first patient had a fusiform aneurysm of the infrarenal aorta. The second patient had a saccular aneurysm of the infrarenal aorta and a fusiform aneurysm of the left internal iliac artery. Both patients had left-sided colorectal carcinoma classified as Dukes' stage B. The two patients underwent a single-stage operation with Hartmann's procedure to avoid graft infection caused by anastomotic leakage. They tolerated the operation and had no postoperative complications including graft infection. A single-stage operation for concomitant AAA and left-sided colorectal carcinoma could be safely performed with Hartmann's procedure in two cases.
