[Abdominal aortic aneurysm with chronic contained rupture in a ninety-year-old woman: a case report].

A 90-year-old woman was admitted to a local clinic with fever, anorexia, and right lower abdominal pain on March 25, 2004. She was referred to our hospital for detailed examination of an abdominal aortic aneurysm on May 18. Computed tomography revealed an abdominal aortic aneurysm measuring 78mm in maximal diameter and a retroperitoneal hematoma, suggesting chronic contained rupture of the abdominal aortic aneurysm. Emergency Y-shaped graft replacement was performed. The intraoperative findings included a perforation on the posterior wall of the abdominal aortic aneurysm and an organized thrombus on the retroperitoneum. The postoperative course was uneventful, and the patient was discharged 21 days after surgery.
