This article collected 50 cases of children’s body material, mainly on the location of the hepatic artery, branches and their parts and the beginning of each branch, location (partial branching), abnormalities made a more detailed observation. The results are compared with other authors. First, the hepatic artery located in the left portal vein, accounting for 34% of the branch in the left hepatic duct sub-most common, accounting for 64%. Liver intrinsic artery is divided into two parts of the right liver and left artery, accounting for 74%. Abnormal hepatic artery, who accounted for 18%. Second, the right hepatic artery in the normal hepatic artery from 39 cases, accounting for 78%, starting in the abdominal common hepatic artery in 4 cases, accounting for 8%. From the superior mesenteric artery in 3 cases, accounting for 6%, starting in other arteries in 4 cases, accounting for 8%. The incidence of vagal replacement artery accounted for 14% of the right accessory hepatic artery 2 cases accounted for 4%. Right hepatic artery by the end of the hepatic duct into the Calot triangle in 32 cases, accounting for 64%, by the hepatic duct and right hepatic duct rear in 7 cases, accounting for 14%, the other by the biliary tract and right portal vein in 12 cases , Accounting for 24%. Regardless of normal or abnormal right hepatic artery, via Calot’s triangular right hepatic lobe, accounting for 74%. Third, the left hepatic artery from the normal hepatic artery, accounting for 76%, starting in the peritoneal liver and left gastric artery, each 10%, from the right liver and left gastric artery accounted for 6% and 8%. The other 4% from other arteries. The incidence of vagal replacement and accessory hepatic left arteries both accounted for 14%. Second, still found in 19 cases of gastric left gastric artery, accounting for 18%; anastomosis in 13 cases, accounting for 26%. Fourth, there are 41 cases in the middle hepatic artery, accounting for 82%; Among them, 24 cases are from the left hepatic artery, accounting for 48%; 13 cases are from the right hepatic artery, accounting for 26%; from other arteries, accounting for 8% %. Double middle hepatic artery only met one case. Middle hepatic artery absent, accounting for 16%. Fifth, the type of branch of hepatic artery: type Ⅰ, accounting for 68%, type Ⅱ, accounting for 12%, type Ⅲ, accounting for 4%, type Ⅳ, accounting for 6%, Ⅴ-Ⅸ type, each 2% .
