Dunbar (or median arcuate ligament) syndrome: A case series

Abstract

Dunbar syndrome (DS) (or median arcuate ligament [MAL] syndrome) is a rare entity of the vascular compression syndrome, where there is focal proximal coeliac axis compression by MAL. It results in an insufficient supply of blood to the respective organs of the gastrointestinal tract. Multidetector computed tomography is a very convenient, noninvasive modality in diagnosing this condition and helpful in distinguishing it from other conditions, such as atherosclerotic disease. DS can further be treated disorder surgically by relieving the compression and sometimes may need vascular reconstruction. We present five cases of the DS.
