Abstract:
Superior mesenteric artery (SMA) syndrome in association with abdominal aortic aneurysm (AAA) is exceedingly rare and has been noted to occur in patients with severe abdominal pain, bilious emesis, and a history of tobacco use. When symptoms of small bowel obstruction occur, it is imperative to investigate further with cross-sectional imaging to determine the etiology. Conservative management is preferred, but in cases of SMA syndrome with concomitant AAA, aneurysm repair should be considered, regardless of size, if initial treatment fails.
