Repair of Celiomesenteric Trunk Aneurysm and Review of the Literature.

Abstract

A celiomesenteric trunk (CMT) is a rare anatomic variant of a common origin for the celiac and superior mesenteric arteries. It is further a seldom occurrence to have aneurysmal dilatation of the CMT. Herein, we describe a patient with a CMT aneurysm and his open surgical repair. The open surgical repair included debranching from the right external iliac artery to the splenic and common origin of the superior mesenteric and common hepatic arteries using a bifurcated knitted graft. Postoperative recovery was unremarkable, and follow-up imaging demonstrated an excluded CMT aneurysm with excellent blood flow to the intra-abdominal organs through the bifurcated graft.
