Frequently Asked Questions

What is the ileal branch of the ileocolic artery?
The ileal branch of the ileocolic artery is an arterial branch arising from the ileocolic artery that supplies the distal ileum, the ileocecal junction, the cecum, and the appendix.
Where is the ileal branch of the ileocolic artery located?
The ileal branch arises from the ileocolic artery in the right iliac fossa and courses toward the terminal ileum and ileocecal region in the mesentery of the small intestine. It runs within the mesoileum to reach its target organs.
What is the function of the ileal branch of the ileocolic artery?
The ileal branch of the ileocolic artery supplies oxygenated blood to the most distal segment of the ileum, the ileocecal junction, the cecum, and the appendix, supporting the absorptive and immune functions of this region.
What conditions may be associated with the ileal branch of the ileocolic artery?
The ileal branch may be involved in mesenteric ischemia of the terminal ileum and Crohn's disease, which preferentially affects the terminal ileum. It is also relevant in appendectomy and right hemicolectomy where this vessel is ligated.
What does the ileal branch of the ileocolic artery look like?
The ileal branch of the ileocolic artery is a medium-sized mesenteric arterial vessel visible on CT angiography within the mesenteric fat of the right iliac fossa, coursing toward the terminal ileum and cecum.
