Median Arcuate Ligament Syndrome
Medial Arcuate Ligament Syndrome (MALS) is a rare condition in which the median arcuate ligament of the diaphragm compresses the celiac artery, potentially affecting blood flow and irritating nearby nerves.
Our experienced vascular and gastrointestinal surgical team provides comprehensive evaluation and individualized treatment for patients with suspected MALS, using advanced diagnostic imaging and minimally invasive surgical techniques when appropriate.

Patients with symptomatic MALS may experience:
