The right gastric artery supplies the right portion of the lesser gastric curvature, anastomosing with the left gastric artery to form the lesser curvature arterial arcade. It is typically small and variable in origin. In total gastrectomy, both right and left gastric arteries are divided. The right gastric is ligated close to the pylorus during Roux-en-Y gastric bypass and sleeve gastrectomy when the lesser omentum is divided.
| Origin | Hepatic artery proper (or sometimes the gastroduodenal or left hepatic) |
|---|---|
| Course | Runs along the lesser curvature of the stomach from the pylorus toward the cardia, anastomosing with the left gastric artery |

The right gastric artery's variable origin makes it one of the vessels that must be identified before hepatic artery procedures, occasionally it arises from an anomalous vessel and must be preserved during hepatic dissection to maintain gastric blood supply.
Right gastric artery division combined with gastroepiploic compromise can produce lesser curvature gastric ischaemia during complex hepato-gastric procedures.
