Abstract
The incidence of false aneurysms, anastomotic stenoses, and ureteric obstruction is reported to be low in patients who have undergone aortic surgery. The use of intravenous peripheral digital subtraction angiography (IVDSA) with completion excretory urography (CEU) may provide a more sensitive means of long-term detection of these complications. The aim of this study was to (1) establish the incidence of anastomotic aneurysms, anastomotic stenoses, and ureteric obstruction after aortic surgery; (2) identify local and systemic factors that predispose to these complications; and (3) evaluate IVDSA as a single radiologic investigation to diagnose these complications. Forty-four patients who had undergone aortic surgery 1 to 12.3 years previously agreed to undergo IVDSA and CEU. False aneurysms were found at 10 distal anastomoses (none at the aorta), for an anastomotic incidence of 11.2% and a patient incidence of 15.9%. Endarterectomy and the femoral artery as a site of distal anastomosis were important factors in the development of anastomotic aneurysms, as were detected radiologi cally at eight aortic anastomosis (18%). There were no distal anastomotic stenoses. Hyper cholesterolemia was more common in this group (62.5%) than in the overall group (21.2%). Three asymptomatic ureteric obstructions were diagnosed in two patients, both of whom had emergency surgery for ruptured aortic aneurysms. The higher incidence of anastomotic aneurysms, anastomotic stenoses, and asymptomatic ureteric obstruction sound merits careful follow-up. IVDSA with CEU may be a simple and effective method of detection.
