What is median arcuate ligament syndrome (MALS)?

Median Arcuate Ligament Syndrome (MALS disease) occurs when the celiac artery (the artery below that diaphragm that stems from the aorta) becomes compressed by the median arcuate ligament. When the median arcuate ligament is restricted, the blood flow is limited to the digestive system which can ultimately lead to significant abdominal pain.

Common MALS Symptoms

Patients experiencing MALS will typically have stomach pain soon after eating. Unfortunately, the only way to prevent pain is to limit or avoid eating, which can cause additional conditions. Patients may also have:

  • Pain
  • Nausea
  • Weight loss
  • Exhaustion, particularly after a heavy meal
  • Inability to exercise

MALS Treatment Options

Our vascular surgeons provide a minimally invasive treatment for MALS disease by laparoscopically releasing the ligament to restore blood flow, which results in shorter hospital stays, less pain and a quicker return to daily activities.
