Median Arcuate Ligament Syndrome Program

Since its inception, our median arcuate ligament syndrome multidisciplinary team has diagnosed and treated this disease in both males and females of all ages from across the world.

MALS is thought to be a multifactorial disease process leading to chronic abdominal pain most commonly following meals. The cause is likely multifactorial, consisting of compression of the celiac artery by the median arcuate ligament compromising blood flow as well as neuropathic pain due to the celiac plexus.

At the University of Chicago Medicine’s Comer Children’s Hospital, our experts utilize leading-edge diagnostic technology, including vascular duplex studies and computed tomography angiography (CTA) along with 3-D imaging. All our pediatric surgeons are proficient in today’s latest laparoscopic techniques, which are employed to release the median arcuate ligament. This procedure is performed in partnership with colleagues specializing in vascular surgery.

Comer Children’s Hospital also offers post-operative support services to children, including repeat duplex imaging and psychiatry, to ensure their physical and mental well-being long into adulthood.
