Superior Mesenteric Artery Syndrome synonyms

Superior Mesenteric Artery Syndrome (SMA syndrome) is a rare gastrointestinal disorder characterized by the compression of the third portion of the duodenum between the abdominal aorta and the superior mesenteric artery. It is frequently referred to by several synonyms, including Wilkie’s syndrome, cast syndrome, and mesenteric root syndrome, all of which describe the same anatomical obstruction.

What are the common synonyms for Superior Mesenteric Artery Syndrome?

Because Superior Mesenteric Artery Syndrome was described by different clinicians throughout the 19th and 20th centuries, it has acquired various names. The most common synonyms you may encounter in medical records or historical literature include:

• Wilkie’s syndrome: Named after David Wilkie, who provided the first comprehensive description of the condition in 1927.


• Cast syndrome: Often used when the condition develops following the application of a body cast for spinal correction, which can lead to rapid weight loss and fat pad reduction.


• Mesenteric root syndrome: A descriptive term referring to the compression occurring at the root of the mesentery.


• Duodenal ileus: A broader clinical term sometimes used to describe the result of the compression.

Why does Superior Mesenteric Artery Syndrome have so many names?

The nomenclature for Superior Mesenteric Artery Syndrome reflects its discovery by multiple specialists, including surgeons and orthopedists. Historically, the condition was often categorized based on the context in which it was found—such as following spinal surgery (cast syndrome) versus idiopathic weight loss (Wilkie’s syndrome). Today, Superior Mesenteric Artery Syndrome is the preferred term in modern medical literature as it provides a precise anatomical description of the underlying pathology.

How is the condition classified in medical systems?

In international databases, Superior Mesenteric Artery Syndrome is categorized to ensure consistent reporting. While it does not have a single dedicated OMIM entry, it is recognized in Orphanet under the classification of rare digestive diseases (ORPHA:93966). Medical professionals utilize these standardized terms to facilitate communication across global health systems and to support the 380 community members on DiseaseMaps.org who are navigating this diagnosis.
