Median arcuate ligament syndrome diagnosed on multi-detector computed tomographic angiography

Abstract

Median arcuate ligament syndrome or coeliac artery compression syndrome is one of the abdominal vascular compression syndromes characterized by postprandial intestinal angina in the expiratory phase of respiration due to focal proximal coeliac root compression by a fibrous ligamentous band with resultant inadequate blood supply to the respectively supplied part of the gastrointestinal tract. Multi-detector computed tomography is extremely useful noninvasive modality in differentiating the cause of compression of the coeliac artery along with evaluation of collaterals due to multiplanar imaging capability.
