A 77-year-old man was transferred to our hospital with a complaint of a sudden abdominal pain after receiving a hard blow to the abdomen. Contrast-enhanced CT revealed rupture of the abdominal aortic aneurysm with a massive retroperitoneal hematoma. Because of severe hemorrhagic shock, he underwent graft replacement with a woven bifurcated graft through a median laparotomy on an emergent basis. His postoperative course was uneventful and now he is doing well 3 years after surgery. Most blunt abdominal aortic injuries are caused by high-energy trauma, such as motor vehicle collisions and fall injuries. Although body blow is considered as a low-energy trauma, abdominal aortic injury could be caused in patients with an abdominal aortic aneurysm.
