Superior mesenteric artery syndrome associated with abdominal aortic aneurysm is a relatively rare disease. A 77-year-old male patient had been suffering from nausea and vomiting for about 2 months and had been suffering from anorexia. He visited his previous doctor for a thorough examination, and CT imaging revealed an abdominal aortic aneurysm, 52 mm in diameter and stenosis of third portion of the duodenum between the superior mesenteric artery and the abdominal aortic aneurysm. He was diagnosed superior mesenteric artery syndrome, as a case of clinical symptoms, and was introduced to our department for that surgical repair. In this case, the patient had history of cerebral infarction. Considering patient’s status, less invasive surgery should have been adopted, but it was necessary to improve duodenal passage, prosthetic graft replacement was performed. We report a case in which an abdominal aortic aneurysm was resected, and the duodenal compression was released, resulting in a cure of superior mesenteric artery syndrome.
