A Case of Endovascular Repair for Inflammatory Abdominal Aortic Aneurysm

Abstract

A 73-year-old man was referred because of sudden abdominal pain. Abdominal computed tomography revealed an abdominal aortic aneurysm with an increase of ventral and lateral aortic wall thickness. The patient underwent endovascular aneurysm repair (EVAR) under general anesthesia with a diagnosis of impending rupture of the inflammatory abdominal aortic aneurysm (IAAA). The postoperative course was uneventful and the patient was discharged from the hospital on the 9th postoperative day. Follow-up CT scan 18 months after the EVAR revealed shrinkage of the aneurysmal sac and regression of periaortic fibrosis.
EVAR for IAAA is technically feasible and safe with low risk of complications such as bleeding and injury to adjacent structures. Moreover, the method may be able to not only exclude the aneurysm but also to reduce perianeurysmal fibrosis.
