The ileal branch is one of two branches of the ileocolic artery, the other being the colic branch.


From the distal end of ileocolic artery, the ileal branch peels off just before reaching the ileocecal junction and passes inferiorly to the ileocecal junction.


The ileal branch gives rise to anterior and posterior cecal arteries and the appendicular artery. It also anastomoses with the distal-most part of the superior mesenteric artery (Dorland, 2011).

Supplied Structures

The ileocolic artery supplies the distal-most ileum, the ileocecal junction, the cecum, and appendix.

When the artery is occluded blood is forced through the collateral vessels, drastically increasing fluid shear stress and triggering an inflammatory response which drives vessel remodeling.
