Incidentally Discovered Middle Mesenteric Artery In A Renal Donor

The middle mesenteric artery is a very rare anomalous artery originating from the ventral surface of the abdominal aorta in-between the superior mesenteric artery and inferior mesenteric artery. We identified a middle mesenteric artery during abdominal computed tomographic angiography in a renal donor patient as a part of his work up. The middle mesenteric artery branched out into ileal and ileocolic arteries, supplying the terminal ileal loops as well as the cecum. The anomalous artery had no effect on patient's eligibility as a renal donor candidate.
