Abstract
We encounterd an abdominal aortic occlusion due to blunt trauma. The patient was a 72-year-old man who received a heavy blow to the abdomen and both legs in a traffic accident. His chief complaint was severe pain in both legs but had no bone fracture. No femoral pulse was found in either leg. Contrast-enhanced computed tomography (CE-CT) demonstrated dissection and occlusion of the infrarenal aorta. The patient was transported to our hospital for further treatment. Another CE-CT was performed and the abdominal aorta and the left iliac artery were recanalized, however the right iliac artery was still occluded. Upon surgery there was no major injury of the abdominal organs. The anterior aspect of the infrarenal aorta was dissected. The abdominal aorta was resected and reconstructed with a Y-shaped Dacron graft. The inferior mesenteric artery was re-implanted. His postoperative course was uneventful. A postoperative CE-CT revealed disappearance of the false lumen. With blunt abdominal trauma, aortic occlusion is rare, however it should be considered, because this condition becomes fatal without appropriate intervention.
