Postoperative computed tomography scanning demonstrated that three IIAAs were still patent and the other six were thrombosed. An increase in the maximum diameter from that at the time of surgery was seen in four IIAAs. One patient suffered serious complications in that a dilated IIAA caused right ureteral obstruction and subsequent hydronephrosis accompanied by unilateral renal dysfunction. This was successfully treated by resection of the IIAA. The findings of this analysis led us to conclude that small IIAAs associated with AAA repair should be treated by either endoaneurysmorrhaphy or resection of the aneurysm after both proximal and distal ligation.
