Abstract
Aortoduodenal syndrome is a rare entity and its main etiology is duodenal obstruction caused by compression of the third portion of the duodenum between the abdominal aortic aneurysm (AAA) and the abdominal wall or the superior mesenteric artery. The case is an 88-year-old woman who visited us with complaints of epigastric pain and vomiting. The infrarenal AAA (maximum diameter 6.7 cm) and obstruction at the third portion of the duodenum were found on the computed tomography (CT). These findings led us to the diagnosis of aortoduodenal syndrome. On admission, she was treated with gastric decompression, fluid administration and correction of electryolyte disturbance for 10 days. On hospital day 11, she underwent AAA repair with open surgery. She had uneventful postoperative course and was discharged on the 26th day after surgery. There was no obstruction of the third portion of the duodenum and the repaired AAA was shrinked on the CT at the 3 months after surgery.
