An accessory or replaced left hepatic artery most commonly arises from the left gastric artery, and passes through the cephalad portion of the gastrohepatic ligament. In that location, it is in danger when the gastrohepatic omentum is opened during Nissen fundoplication.

The cystic artery most often (75%) arises as a single trunk within the hepatocystic triangle. It divides into a superficial branch on the free surface of the gallbladder and a deep branch in the gallbladder bed. Twenty five percent of the time there are independent origins of the two branches, and they may originate outside of the hepatocystic triangle. The cystic artery is rarely larger than 3 mm in size.
