Median arcuate ligament syndrome (Dunbar syndrome)

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.

We present a 53-year-old female patient with median arcuate ligament syndrome (MALS), also known as Dunbar syndrome or celiac artery compression syndrome, related to lumbar lordosis and hip dysplasia. She utilized interprofessional management strategies, which were beneficial in reducing lumbar lordosis and MALS-related symptoms. This finding is important because there are no other reports in the literature describing interprofessional strategies to manage symptoms for patients who are waiting for surgery or are not candidates for surgery.

Abdominal Bruit

Median arcuate ligament syndrome (MALS) is a condition characterized by pain in the abdominal region attributed to compression of the celiac artery by the median arcuate ligament of the diaphragm during expiration. MALS is also known as celiac artery compression syndrome, celiac axis syndrome, or Dunbar syndrome. Pain may result from the tight pressing on the celiac nerves in the area. The patient usually presents with symptoms such as postprandial epigastric pain, weight loss, and, occasionally, an abdominal bruit. Furthermore, some individuals may experience nausea and vomiting. It may be an etiology of a rare disorder, chronic mesenteric ischemia.

Dunbar Syndrome

Median arcuate ligament syndrome (MALS) is a rare entity characterized by extrinsic compression of the celiac artery and symptoms of postprandial epigastric pain, nausea, vomiting, and weight loss mimicking mesenteric ischemia. The following case illustrates a rare cause of abdominal pain, where this young woman was found to have celiac trunk stenosis , secondary to compression of the trunk by the median arcuate ligament. She underwent a successful stenting to the ostial celiac trunk, thus reliving her symptomatically. Decompression of the celiac artery is the general approach. Usually post PTA, once revascularisation is achieved, 75% of the patients remain asymptomatic at follow up.
