The branch of the hepatic artery supplies oxygen-rich blood to the liver, the duodenum, the pylorus, and the pancreas. Frequently, the hepatic artery doesn’t have the usual set of branches; this is because one of the typical branches may originate from a different place than the proper hepatic artery. There are two kinds of aberrant (variant) hepatic arteries: accessory and replacing. Aberrant accessorymycontentbreak hepatic arteries are extra branches off of the normal hepatic arteries. Replacing hepatic arteries are those which substitute for one of the standard hepatic arteries (if it is absent).
