Celiac revascularization as a requisite for treating the median arcuate ligament syndrome.

Median arcuate ligament syndrome (MALS) is a rare and often misunderstood condition characterized by compression of the proximal portion of the celiac artery by the median arcuate ligament. The existence of MALS, also called "celiac artery compression syndrome" or "Dunbar syndrome," has been questioned since compression of the celiac artery is often demonstrated on aortography in asymptomatic patients. Additionally, isolated stenosis of the celiac artery can be compensated for by collateral circulation from the superior mesenteric artery. Despite these dissenting arguments, there are many cases of patients with this syndrome whose symptoms have been relieved by surgical division of the median arcuate ligament. We report on a case involving a patient with similar symptoms not only to provide further support for the validity for this syndrome but also to emphasize the critical need for revascularization once pathological changes develop in the celiac artery.
