title: Diagnosis and management of 17 consecutive patients with inflammatory abdominal aortic aneurysm.
abstract: This report reviews the authors' experience in diagnosing and managing 17 consecutive patients with inflammatory abdominal aortic aneurysm (AAA). Among 491 patients undergoing repair for AAA during a 10-year period, 17 (3%) had evidence of associated periaortic fibrosis, which was confirmed histologically. No patient had acute rupture, and two patients (12%) had chronic contained rupture. Ureteral obstruction was evident in seven patients. In 41% of the patients, available surgical correlation demonstrated that computed tomographic (CT) scan accurately delineated the extent of the disease. Sixteen patients underwent aneurysm resection. Ureteral obstruction was relieved by ureterolysis in three patients treated early in this series. In the last period of the study, well-documented hydronephrosis spontaneously subsided in two patients without special treatment. Of these 17 patients, 15 (88%) were early (30-day) survivors. There were two late deaths at 2 months and 5 years; 12 (71%) patients are still alive and free of symptoms up to 10 years after operation. On the basis of our study, we conclude the following: (1) precise preoperative diagnosis and detailed anatomic information are widely available with CT; (2) aneurysm resection is the treatment of choice because the risk of rupture still exists, and this procedure seems to reverse the inflammatory process; (3) good early and late results can be expected with proper surgical technique; and (4) routine follow-up with CT is recommended to document resolution or progression of the fibrotic process after aneurysm resection.
