Median arcuate ligament syndrome was first described in 1963 by Harjola. Diagnosis is based on a combination of clinical and radiological features. It usually affects young patients (20-40 years) and is more common in thin women. The symptoms are due to extrinsic compression of the celiac axis by the median arcuate ligament resulting in impaired blood flow. During impairment, a sudden decrease in vessel diameter is noted along the proximal celiac axis, usually within 5 mm of its origin from the abdominal aorta. The symptoms of nausea and vomiting are due to secondary gastroparesis.
