“…The pattern of blood supply to the colon has implications on the surgical techniques and treatment outcomes on various pathological conditions involving the colon. In the surgical treatment of invasive colonic malignancies, for example, resection of the involved colon is usually accompanied with ligature of the accompanying arterial branches [1, 6]. Accidental colonic hemorrhage and ligature of anomalous arteries with subsequent infarction of the affected organs are some of the complications that could result from undetected variations in the blood supply of the colon [6].…”

Accidental colonic hemorrhage and ligature of anomalous arteries with subsequent infarction of the affected organs are some of the complications that could result from undetected variations in the blood supply of the colon [6]. Most of the lymphatic vessels draining the colon run in association with blood vessels, it is therefore critical for surgeons to appreciate the variations in the blood supply of the colon for maximum possible lymphatic field excision in colonic resections due to cancer.…”

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.

“…Failure to recognize these variations may result in either a false-positive diagnosis such as branch occlusion or in a false-negative diagnosis in the supplied segment of the colon [2]. In fact, LeQuire et al [4] reported on a case in which an MMA with an unusual vascular distribution supplied the splenic flexure and was the source of hemorrhage in a 62-year-old man. Although there have been no reports of associated anomalies, further investigation is certainly warranted.…”

“…In all previously reported cases [1][2][3][4], it arose from the aorta between the superior and inferior mesenteric arteries and mainly supplied the transverse colon. In the present report, a patient with a middle mesenteric artery supplying the cecum, the entire ascending and transverse colon, and the splenic flexure is described.…”

Middle mesenteric artery visualized by computed tomographic angiography

The middle mesenteric artery, a third mesenteric artery arising from the aorta that principally feeds the transverse colon, is an extremely rare anomaly. We identified a middle mesenteric artery branching into the ileocolic artery and into the right, middle, and accessory middle colic arteries. It supplied the cecum and the entire ascending and transverse colon. This anomaly was detected with computed tomographic angiography.

“…A selective study of this anomalous vessel demonstrated, in contrast to other authors, the supply of the ileocolic, right colic, and middle colic branches. 7 In 1999, Koizumi et al incidentally visualized a third mesenteric artery by CT-angiography scan. It branched out into the ileocolic artery and the right, middle, and accessory middle colic artery.…”

Middle mesenteric artery arising from an inflammatory infrarenal aortic aneurysm

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.
