Abstract
We report a rare case of duodenal obstruction caused by superior mesenteric artery syndrome (SMAS) associated with a huge abdominal aortic aneurysm (AAA). An 89 year-old male was admitted to our hospital due to massive hematemesis. Gastrointestinal endoscopy showed gastroesophageal reflux disease and Mallory-Weiss syndrome. Computed tomography revealed duodenal obstruction due to SMAS caused by a 9.0 cm-diameter infrarenal AAA. After his condition was ameliorated by hydration therapy and blood transfusion, a graft replacement of the abdominal aorta was performed. The post operative course was uneventful. Graft replacement of AAA is useful to release ileus by SMAS and is strongly recommended.
