Origin

As the left colic artery approaches the descending colon, it bifurcates into ascending and descending branches.

Course

The ascending branch of the left colic artery takes a superior course along the medial aspect of the descending colon. It tracks the superior portion of the descending colon, the left colic flexure, and the right one half to one third of the transverse colon.

Branches

The ascending branch terminates at the midgut-hindgut junction by an anastomosis with the left branch of the middle colic artery.

Supplied Structures

The ascending branch of the left colic artery supplies the superior portion of the descending colon, the left colic flexure, and the right one half to one third of the transverse colon.
