Abstract:

Objective　To provide anatomic basis for liver transplantation of treeshrew.　Methods　Through anatomy of 12 adult treeshrews, the liver morphology and adjacency, the main blood vessels and biliary duct were observed and measured. Three groups of treeshrews was performed liver transplantation by two cuff method.　Results　The diameter of hepatic artery came from the celiac trunk was about  (0.63±0.21) mm, and that of the superior hepatic inferior vena cava  away from the diaphragm about  (5.35±0.55) mm was  (6.86±0.61) mm. The diameter of inferior hepatic inferior vena cava was (5.28±0.58) mm, and that of the portal vein composed by the superior mesenteric vein and splenic vein was (3.86±0.57) mm. The length of common bile composed by the cystic duct and general hepatic duct duct was (15.5±2.6) mm, and the diameter  (0.75±0.12) mm. Three groups of treeshrews were operated liver transplantation successfully and the survival time of postoperative were 3h, 5h and 6h respectively.　Conclusions　On the anatomic basis, the establishment of liver transplantation of treeshrew is a certain feasible.
