Median arcuate ligament
Template:Short description Script error: No such module "Infobox".Template:Template otherScript error: No such module "Check for unknown parameters". The median arcuate ligament is a ligament under the diaphragm that connects the right and left crura of diaphragm.
Structure
The median arcuate ligament is formed by the right and left crura of the diaphragm.[1] The crura connect to form an arch, behind which is the aortic hiatus, through which pass the aorta, the azygos vein, and the thoracic duct.
Variation
In between 10% and 24% of people, the median arcuate ligament occurs very low.[2]
Clinical significance
Compression of celiac artery and celiac ganglia by the median arcuate ligament being too low in some individuals;[3] can lead to the median arcuate ligament syndrome, which is characterized by abdominal pain, weight loss, and an epigastric bruit.[4]
