The right colic artery is an artery of the abdomen, a branch of the superior mesenteric artery supplying the ascending colon. It divides into two terminal branches - an ascending branch and a descending branch - which form anastomoses with the middle colic artery, and ileocolic artery (respectively).

The right colic artery may be removed during a right hemicolectomy.

Structure

The right colic artery is a relatively small and variable artery.^[1] It affords arterial supply to the ascending colon.^[2]

Origin

The right colic artery is a branch of the superior mesenteric artery.^[2]^[3] It usually arises from a common trunk with the middle colic artery, but may also arise directly from the superior mesenteric artery, or from the ileocolic artery.^[4]

Course

It passes right-ward posterior to the peritoneum, and anterior to the right gonadal vessels, the right ureter, the psoas major muscle, passing toward the middle of the ascending colon.^[5]

Sometimes, it lies at a higher level, and crosses the descending part of the duodenum and the inferior extremity of the right kidney.^[5]

At the colon, it divides into a descending branch and an ascending branch. These branches form arches, from the convexity of which vessels are distributed to the ascending colon.^[5]

Branches and anastomoses

The descending branch anastomoses with the ileocolic artery.^[5]

The ascending branch anastomoses with the middle colic artery.^[5]

Variation

The right colic artery is quite variable.^[1] It is absent in around 10% of individuals.^[6]

Clinical significance

In a right hemicolectomy to remove the caecum and the ascending colon, the right colic artery is ligated and removed.^[2]^[7] Ligation is performed close to the origin of the right colic artery from the superior mesenteric artery.^[7]

If part of the superior mesenteric artery is missing due to a congenital abnormality, the right colic artery may supply part of the ileum.^[8]
