title: Superior mesenteric artery syndrome following surgery for scoliosis.
abstract: METHODS
  A retrospective report of three cases outlining upper intestinal obstruction as a rare complication following surgery for scoliosis.
  
  
  OBJECTIVE
  To present the clinical features, progression, and management of duodenal obstruction due to superior mesenteric artery compression after surgical treatment of scoliosis.
  
  
  BACKGROUND
  Superior mesenteric artery or cast syndrome has been reported historically in the literature. Many causes are described, among which is the complication of the surgical and nonoperative treatment of scoliosis.
  
  
  METHODS
  Three adolescent patients were investigated for nausea and vomiting following surgical correction of scoliosis.
  
  
  RESULTS
  Contrast radiography confirmed extrinsic obstruction of the third part of the duodenum by the superior mesenteric artery in all three patients. They were jointly managed with the gastrointestinal surgeons. Two patients recovered with conservative treatments, but the third required operative intervention with a laparotomy.
  
  
  CONCLUSIONS
  Vomiting following surgery for scoliosis should be investigated thoroughly, as superior mesenteric artery syndrome carries significant morbidity, protracted hospital stay, and potential mortality.
