Superior Mesenteric Artery Syndrome

Superior Mesenteric Artery Syndrome (pronunciation: su·pe·ri·or mes·en·ter·ic ar·ter·y syn·drome) is a rare gastrovascular condition that occurs when the duodenum, the first part of the small intestine, is compressed between the abdominal aorta and the superior mesenteric artery.

Etymology

The term "Superior Mesenteric Artery Syndrome" is derived from the anatomical structures involved in the condition. The superior mesenteric artery is a large blood vessel that supplies blood to the small intestine, large intestine, and appendix. The term "syndrome" is used to describe a collection of symptoms that often occur together.

Symptoms

Symptoms of Superior Mesenteric Artery Syndrome include nausea, vomiting, abdominal pain, and weight loss. These symptoms are often exacerbated by eating, as the act of digestion requires the duodenum to expand, which can increase the compression caused by the superior mesenteric artery.

Diagnosis

Diagnosis of Superior Mesenteric Artery Syndrome is typically made through a combination of medical history, physical examination, and imaging studies such as computed tomography (CT) scans or magnetic resonance imaging (MRI).

Treatment

Treatment for Superior Mesenteric Artery Syndrome typically involves dietary changes to reduce the pressure on the duodenum, and in severe cases, surgery may be required to reposition the superior mesenteric artery.
