Median Arcuate Ligament Syndrome

Our MALS program is part of a multidisciplinary team composed of vascular surgeons, pediatric surgeons, interventional radiologists, clinical social workers and psychologists. Together, they have extensive experience diagnosing and treating the disease in patients of all ages. 

At the University of Chicago Medicine, the MALS team uses ultrasonography and computed tomography (CT) angiography along with 3-D imaging to screen for MALS. If a MALS diagnosis is confirmed, our vascular surgeons offer laparoscopic treatment to release compression on the median arcuate ligament and restore blood flow to the digestive system.

Patients with undiagnosed MALS may present with common symptoms, such as pain, nausea, weight loss and exhaustion, so physicians with questions about a particular case are welcome to reach out to our academic office at any time. Whenever a patient does come into our program, the team is dedicated to working closely with his or her other physicians to ensure continuity of care.
