Abstract
A 77-year-old was admitted to the emergency center for abdominal pain. As the patient complained of cerebral infarction aftereffects and sensory deafness, he could not express his condition sufficiently and abdominal pain was gradually alleviated. Thus the patient was directly admitted to the Department of Gastrointestinal Medicine. However abdominal pain recurred, and abdominal Echo graphy and CT showed signs of a ruptured abdominal aortic aneurysm with a great hematoma in the retroperitoneum. Y-shaped artificial graft replacement was successful. The postoperative course was uneventful and he was discharged on postoperative day 35. We report this case because operative timing was delayed because the patient could not express his symptoms due to aftereffects of a cerebral infarction.
