Left gastric artery is the largest artery to the stomach and in 15-20% cases, there is an aberrant left hepatic artery which arises from it.

Right gastric artery is the branch of common hepatic artery or Gastro duodenal artery
Aberrant left hepatic artery is the branch of Left gastric artery. It is seen in 15-20% cases.
Right gastro epiploic artery is the branch of Gastro duodenal artery and left gastro epiploic from splenic artery
