Is tube repair of aortic aneurysm followed by aneurysmal change in the common iliac arteries?

To address the concern that tube repair of an abdominal aortic aneurysm might be followed by aneurysmal change in the common iliac arteries, 23 patients who had undergone the operation were re-examined 3 to 5 years later. Although 9 had had minimal ectasia of these arteries preoperatively, in none of the 23 was there symptomatic or radiologic evidence of aneurysmal change on follow-up. Measurements of the maximum intraluminal diameters were made by computed tomography; they indicated no significant differences between the preoperative and follow-up sizes of the common iliac arteries. The variation in time to follow-up also showed no significant correlation with change in artery diameter.
