Middle Mesenteric Artery Encountered during Abdominal Aortic Aneurysm Surgery

Abstract

We encountered a case of middle mesenteric artery during abdominal aortic aneurysm repair. This third mesenteric artery arose from the ventral surface of the aneurysm between the superior and inferior mesenteric arteries and supplied the transverse colon; it anastomosed with the oral and anal marginal arteries. This is the eleventh report of this rare anomaly.
