We have described the anatomical variations in the ramification of the hepatic artery of males and females adult pigs. The hepatic artery of in block removed ­ stomach, liver and duodenum specimens (n=30), was injected of neoprene latex and dissected. The ramification of the hepatic artery in these animals presented three basic patterns: trifurcation, bifurcation and quadruple ramification, giving origin to vessels supplying the lobes of the liver and neighboring structures. In these three patterns the hepatic artery may or may not posses collateral branches
