Abstract
We report a rare case of contained rupture of abdominal aorta which was not dilated. The patient was successfully treated by replacement of ruptured aorta with a straight graft. A 64-year-old man with previous history of coronary artery disease and lung cancer was referred to our department for rapidly progressed abdominal aortic dilatation. Contrast computed tomography (CT) of the abdomen showed dilatation of infrarenal abdominal aorta, suggesting a pseudoaneurysm associated with possible contained rupture of the aorta. These findings were not seen in the CT performed two months prior to the admission. Patient underwent urgent repair of the aortic aneurysm. Intraoperative findings included severe adhesion around the abdominal aorta and a punched-out defect in the posterior wall of the incised aneurysm. Therefore, we diagnosed chronic contained rupture of abdominal aorta. Subsequently, the aneurysm was replaced with a straight graft. Postoperative course was unremarkable and the patient has been doing well one year after the operation.
