Open Surgical Repair for Inflammatory Abdominal Aortic and Iliac Artery Aneurysms

This study was performed to investigate the outcomes of surgical treatment for inflammatory abdominal aortic aneurysms (IAAAs) and inflammatory iliac artery aneurysms (IIAAs).

We retrospectively reviewed the charts of patients who underwent open surgical repair (OSR) between January 2000 and June 2013.

Nine male and 2 female patients (median age, 67 years) were treated. Five of the 11 patients who underwent OSR developed hydronephrosis, and ureteral stents were placed preoperatively. There were no intraoperative complications during OSR. After OSR, the conditions of 4 of 5 patients with preoperative hydronephrosis improved. During the follow-up period with a mean of 51 months (range, 6-120 months), 2 patients with OSR developed aneurysmal changes at the anastomosis site (84 and 21 postoperative months, respectively), and reintervention for both patients was needed. One patient died because of malignant disease at 96 months postoperatively.

OSR can be safely performed for IAAAs and IIAAs. When an inflammatory aneurysm, especially an IIAA, is complicated by hydronephrosis, OSR might be an effective treatment procedure.
