Regression of Perianeurysmal Fibrosis and Ureteral Dilation following Endovascular Repair of Inflammatory Abdominal Aortic Aneurysm

An inflammatory component to abdominal aortic aneurysms (AAA) is thought to occur in approximately 5% of cases. Accompanying ureteral entrapment may be involved in 20% of these. Transabdominal repair of inflammatory AAA with ureterolysis may result in increased complications. Many authorities have recommended a retroperitoneal approach to decrease dissection. Similarly, an endovascular approach has been utilized. We report here the results of a patient with an inflammatory AAA with bilateral ureteral obstruction successfully treated with endovascular stent graft repair and bilateral ureteral stents with exclusion of the aneurysm and resolution of hydronephrosis.
