Abstract
Background:Duodenal obstruction caused by abdominal aortic aneurysm (AAA) and abdominal wall or superior mesenteric artery (SMA), is relatively rare. We report 2 cases of obstruction of duodenum sandwiched by AAA and SMA or abdominal wall and a review of literatures. Cases: Case 1: the 81-year-old man, with a chief complaint of frequent vomiting. He was referred by a local doctor. On computed tomography (CT) scan, obstruction of the duodenum sandwiched by AAA (maximum diameter 75 mm) and SMA was diagnosed. Case 2: 71-year-old man with frequent vomiting after oral intake as a chief complaint. A pulsatile mass in the abdomen was found. On CT scan, the obstruction of duodenum sandwiched between the AAA (maximum diameter 65 mm) and the abdominal wall was found. Results: In both cases, bifurcated graft replacement surgery was performed and the symptoms subsided. Conclusion: Both cases of ileus due to obstruction by an AAA and abdominal wall or SAM were successfully treated.
