Background:
Background:
Superior mesenteric artery syndrome (SMAS) is caused by compression of the third part of the duodenum between the superior mesenteric artery and the aorta. It occurs most frequently in patients with rapid weight loss.
Methods:
We report two young patients, who each presented with a longstanding history of postprandial abdominal pain, nausea, and voluminous vomiting. The diagnosis of SMAS was established by digital fluoroscopy and contrast-enhanced spiral computed tomography (CT) scan. The findings obtained by endoscopic ultrasound (EUS) at the site of duodenal compression, using a miniprobe, were of substantial diagnostic value and in good agreement with the radiological observations.
Results:
Both patients, once diagnosed, were treated conservatively by providing enteral or parenteral high caloric nutrition. Weight gain was accompanied by the complete relief of symptoms.
Conclusions:
Pathogenesis, diagnostic procedures, and therapy are reviewed in order to draw attention to this rare entity.
