Superior Mesenteric Artery Syndrome in an Intravenous Drug Abuser After Rapid Weight Loss

Superior mesenteric artery (SMA) syndrome is a form of small-bowel obstruction due to vascular compression of the duodenum. We describe a case of SMA syndrome in an intravenous drug abuser who had rapid weight loss during a 2-week drug binge. Radiographic studies are necessary to confirm the diagnosis, and our case illustrates the value of computed tomography in diagnosing this relatively rare but serious disorder. The management of this syndrome requires reversing or removing the precipitating factors as well as correcting any secondary complications. Increased awareness of this condition may result in improved recognition and timely management of this rare cause of high intestinal obstruction, thus reducing its potential morbidity and complications.
