Superior Mesenteric Artery Syndrome: A Case Report and Literatures Review

Superior mesenteric artery syndrome (SMAS) is a rare clinical disease caused by obstruction of the duodenum at the angle between the abdominal aorta and superior mesenteric artery. We report a male patient admitted to our hospital with a chief complaint of obvious postprandial vomiting and nausea. SMAS was confirmed by abdominal computed tomography images and clinical symptoms. After admission, the patient was treated with fasting, antibiotics, fluid resuscitation, parenteral nutrition, and other conservative treatments. However, the patient deteriorated rapidly and died because of multiple organ failure. SMAS is easily missed, which may delay timely treatment. Clinicians should improve their clinical understanding of SMAS.
