Several omental branches arise from the left gastroomental artery. The first instance of an omental branch arises closest to the spleen and is particularly long.


Each of the several omental branches passes inferiorly between the descending layers of the greater omentum (gastrocolic portion). The first branch, which is particularly long, descends along the left edge of the greater omentum.


There are no named branches.

Supplied Structures

The omental branches of the left gastroomental artery supply the greater omentum (approximately left half).
