Acute mesenteric ischemia caused by isolated superior mesenteric artery dissection.

Isolated dissection of a peripheral artery is a rare event. Only 11 reports exist in the literature of dissection of the superior mesenteric artery, most of which have been fatal. This is the first documented case of the successful treatment of an acute ischemic event caused by a superior mesenteric artery dissection. In addition, the new technique of right gastroepiploic artery-to-superior mesenteric artery bypass is introduced as a satisfactory method of revascularization.
