Aortitis and bilateral ureteral obstruction after endovascular repair of abdominal aortic aneurysm.

A bifurcated stent graft was used to treat an asymptomatic 5.4-cm abdominal aortic aneurysm in a 76-year-old man. No endoleaks or inflammatory changes were seen on the 1-month follow-up computed tomography scan. Five months later the patient had acute renal failure and ureteral obstruction secondary to significant inflammatory changes in the aneurysm wall. After bilateral ureteral stenting, conservative treatment included tamoxifen and steroid therapy. The patient remains symptom-free, and at 2-year follow-up a computed tomography scan demonstrated decreased inflammation and shrinkage of the excluded abdominal aortic aneurysm.
