Left Gastric Artery
The left gastric artery is the celiac trunk's narrowest branch. It runs up to the left and to the rear of the posterior peritoneum's ascending layer and then goes towards the lesser curvature of the stomach's superior end. The artery delivers branches to the esophagus that anastomose with the aortic esophageal branches.
It also sends a hepatic branch that flows up and to the right amid the lesser omentum layers toward the cardiac end of the stomach's cardiac branches and the liver. The left gastric artery flows from left to right, adjacent to the lesser curvature of the stomach to the pylorus, between the lesser omentum layers. Both surfaces of the stomach receive gastric branches. On the lesser curvature of the stomach, the right gastric branch of the hepatic artery and this part of the vessel merge.
