What is SMAS?

SMAS, or Superior Mesenteric Artery Syndrome, is the compression of the 3rd portion of the duodenum between the Abdominal Aorta (AA) and the Superior Mesenteric Artery (SMA). SMAS is also known as Wilkie’s Syndrome or Cast Syndrome. SMAS can develop naturally or due to traumatic injury. There are other related symptoms and syndromes such Nutcracker Syndrome, Pelvic Varicose Veins, Reverse Peristalsis, Gastroparesis, Gallbladder failure, and Malabsorption Syndrome.

Superior Mesenteric Artery Syndrome is a rare gastro-vascular illness that affects less than .013% of the world’s population.

GARD states: “Researchers have made several estimates of the prevalence rate of SMA syndrome in the population.  These estimates have ranged from 0.013% to 0.3% in the general population, which translates roughly to 41,000 to 96,000 Americans with SMA syndrome.[1][2][3]  Most of the prevalence rate estimates quoted in recent published articles can be traced back to studies done between 1956-1966.[4][5]  Recent studies to determine the prevalence rate of SMA syndrome do not seem to be available, making it difficult at present to give a more accurate estimate.”
