Abdominal Aortic Aneurysm and Retroperitoneal Fibrosis

Abstract

Until changes of ureteric or vascular compromise are noted, retroperitoneal fibrosis usually goes unnoticed. When symptomatic retroperitoneal fibrosis has been associated with abdominal aortic aneurysm, ureteral involvement has uniformly been present. Three cases demonstrate a new ultrasonographic picture that can aid in early identification of retroperitoneal fibrosis before complications are manifest. In patients with abdominal aortic aneurysms, routine sonography may identify unsuspected retroperitoneal fibrosis, a factor that may be important in preoperative planning for safe surgical intervention.
