Median arcuate ligament syndrome is compression of the celiac artery — an artery that originates from your aorta just below the diaphragm — by the median arcuate ligament, a part of the diaphragm that connects the diaphragm with the vertebrae between the ribs and pelvis.
The median arcuate ligament usually passes above the beginning of the celiac artery. When it passes lower, it can compress the artery and cause median arcuate ligament syndrome.
You may have arcuate ligament syndrome if you experience:
- Abdominal pain
- Weight loss
