Celiac Artery Compression Syndrome: A Literature Review

Celiac artery compression syndrome, also known as median arcuate ligament syndrome and Dunbar syndrome, is a rare cause of chronic mesenteric ischemia. Ischemia results from external compression of the proximal celiac artery during respiration, typically during expiration, by the median arcuate ligament just below the diaphragm. The author reviews the current literature to highlight the most common signs and symptoms, the imaging features, and the treatment options associated with celiac artery compression syndrome.
