Lessons learned from a case of multivessel median arcuate ligament syndrome in the setting of an Arc of Buhler
Abstract
The median arcuate ligament (MAL) can rarely compress both the celiac axis and superior mesenteric artery. We present a case of a 70-year male who presented with isolated episodes of upper abdominal pain and diarrhea associated with sweats and nausea. Angiography images demonstrated complete occlusion of the celiac axis and compression of the superior mesenteric artery during the expiration phases. The celiac axis was reconstituted distal to its origin by a patent Arc of Buhler. Other reported cases of multivessel MALs have produced severe symptoms in young adults requiring surgical and/or endovascular intervention. In this case, our patient's Arc of Buhler was protective against more severe chronic mesenteric ischemia. We suggest that a patent Arc of Buhler is protective against symptoms in a single vessel MALs patient. A significant percentage of patients receiving surgical intervention for MALs do not have relief of symptoms. There should be a search for an Arc of Buhler before surgical management of patients suspected to have single vessel MALs.
