Superior mesenteric artery syndrome occurs when the angle between the superior mesenteric artery and aorta is less than 18 degrees, causing duodenal compression. Surgical intervention, specifically duodenojejunostomy, is the recommended treatment.

Area of Science:

  • Gastroenterology
  • Vascular Surgery
  • Anatomy

Background:

  • Superior mesenteric artery syndrome (SMAS) is a clinical condition resulting from the acute vascular compression of the duodenum.
  • It is characterized by symptoms such as recurrent vomiting, abdominal distention, weight loss, and postprandial distress.

Observation:

  • The syndrome is caused by a narrowed angle between the superior mesenteric artery (SMA) and the aorta, typically less than 18 degrees.
  • This anatomical variation can lead to compression of the third part of the duodenum.

Findings:

  • The primary finding is the identification of the critical angle between the SMA and aorta as the etiological factor.
  • The study highlights duodenojejunostomy as the optimal surgical treatment for SMAS.

Implications:

  • Accurate diagnosis of SMAS is crucial for timely intervention.
  • Duodenojejunostomy offers an effective solution for patients suffering from this vascular compression syndrome.
