Blood supply of stomach is mostly consistent and there are four named arteries.

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. 

At least three arteries of the stomach can be safely ligated if the arcades on the greater and lesser curvatures are preserved and vascularity of whole of stomach may be preserved.
