Increase Body Weight to Treat Superior Mesenteric Artery Syndrome
Overview
Affiliations
Introduction: Superior mesenteric artery (SMA) syndrome is a rare cause of duodenal obstruction resulting from vascular compression of the third part of the duodenum in the angle between the abdominal aorta and SMA.
Case Presentation: A 19-year-old woman with anorexia nervosa with upper gastrointestinal obstruction symptoms resorted to the emergency department. A diagnosis of SMA syndrome was made. Symptoms were solved with conservative treatment aimed at increase body weight.
Discussion: SMA syndrome is most commonly associated with debilitating illnesses. Patients present with acute or insidious upper gastrointestinal obstruction symptoms. Aortomesenteric artery angle of ≤25° is the most sensitive measure of diagnosis. Advances in both enteral and parenteral nutrition led to a shift towards conservative treatment.
Conclusions: Low threshold of suspicion is important to make a timely diagnosis and treatment. A conservative treatment aimed at increasing body weight is the first-line approach, leaving surgical intervention for failure cases.
