Endovascular Repair of Ruptured Inflammatory Abdominal Aortic Aneurysm Developing from Periaortitis

Abstract

Periaortitis is a rare condition whose etiology, aneurysm formation mechanism, and clinical features remain undefined. Here, we report the case of a 71-year-old Japanese male with a 5-year history of suspected and untreated primary abdominal periaortitis that was complicated by inflammatory abdominal aneurysm rupture. The patient underwent an endovascular aneurysm repair (EVAR) procedure at 14 days after initial admission, because consent for surgery was not obtained at initial admission. The patient remains well and without any complications at the recent follow-up visit at 6 months after the surgery; however, long-term follow-up is required to validate the efficacy of EVAR for inflammatory abdominal aortic aneurysm.
