Dunbar (Or Median Arcuate Ligament) Syndrome: A Case Series

Abstract

Dunbar syndrome (DS) (or Median arcuate ligament syndrome) is a rare entity of the vascular compression syndrome, where there is focal proximal coeliac axis compression by Median arcuate ligament (MAL). It results in an insufficient supply of blood to the respective organs of the gastrointestinal tract (GIT). Multi-detector computed tomography (MDCT) is a very convenient non-invasive 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.
