“…There is great similarity in the origin, course and the branching pattern of the third mesenteric artery observed in our case report and a similar case reported by Benton and Cotter [2]. Other cases with a third mesenteric artery, but with branching pattern different to our case report have also been reported [5, 8]. In these cases, the variant artery arose from the aorta between the SMA and IMA, ascended to the right and branched into the ileocolic, right and middle colic arteries.…”

A variant source of arterial supply to the ascending, transverse and descending colon

Anatomic variations involving arterial supply of the large intestines are of clinical significance. Variations range from the pattern of origin, branching and territorial supply. The colon, the part of the large intestine, usually receives its arterial blood supply from branches of the superior and inferior mesenteric arteries. However, anatomic variation in this vascular arrangement has been reported, with vascular anatomy of the right colon being described as complex and more variable compared with the left colon. During routine cadaveric dissection of the supracolic and infracolic viscera, we encountered an additional mesenteric artery originating directly from the anterior surface of the abdominal aorta between the origins of the superior and inferior mesenteric arteries. This additional “inferior mesenteric artery” ran obliquely superiorly toward the left colon giving rise to two branches supplying the distal part of the ascending colon, the transverse colon and the proximal part of the descending colon. Awareness and knowledge of this anatomic variation are important for radiologists and surgeons to improve the quality of surgery and avoid both intra- and postoperative complications during surgical procedures of the colon.

“…The variant artery reported in this case took its origin from the abdominal aorta between the SMA and IMA before giving rise to two branches that correspond to the middle and left colic arteries. Case reports of variant arteries arising directly from the aorta between the SMA and IMA have previously been documented [5, 8].…”

We report of a patient with an inflammatory infrarenal aortic aneurysm with a diameter of 6.5 cm, a middle mesenteric artery (MMA) arising from the aneurysm, and a review of the literature. The patient underwent successful surgical treatment by using an interposition tube graft (Dacron graft, 18 mm) with replantation of the MMA. Reports about a MMA arising separately from the aorta are extremely rare, especially in combination with an infrarenal aortic aneurysm. In our case, it arose from the anterior aspect of the abdominal aorta, 6 cm below the superior mesenteric artery (SMA) and 1.2 cm above the inferior mesenteric artery (IMA). The MMA gave branches to the ileum and distal jejunum and supplied the iliocolic and middle colic artery branch as well as the left colic artery branch. It is of extreme clinical importance for the surgical procedure to have a detailed knowledge of the different anatomical variations and anomalies.
