[Superior mesenteric artery syndrome--rare case report].

Superior mesenteric artery syndrome is a condition caused by the compression of the third part of the duodenum between the superior mesenteric artery and the aorta. We present the clinical case of a patient, a female, 18 years old, with history of two days' evolution characterized by postprandial epigastric colic, accompanied by nausea and intractable vomiting. Applied conservative management was insufficient. The patient was successfully treated with open duodenojejunostomy.
