Median arcuate ligament

Last revised by Ciléin Kearns on 21 Jan 2023

The median arcuate ligament is a fibrous arch connecting the left and right diaphragmatic crura at the aortic hiatus 1,2.

A low-lying median arcuate ligament can compress the celiac axis to cause celiac artery compression syndrome which is also known as median arcuate ligament syndrome (MALS) 2.
