Patterns of arterial supply of the human fetal liver. The significance of the accessory hepatic artery.

One or two aberrant hepatic arteries were found in 30% of human fetal livers. The liver received a triple or double arterial supply. The aberrant artery arises from the left gastric or superior mesenteric arteries and supplies an entire lobe or more without joining the branches of the usual hepatic artery in 38.5%. The artery has an important significance for the arterial supply of the fetal liver.
