Abstract: Objective To provide applied anatomic evidence for the blood supply to the bile ducts in the complication relating to the bile ducts in the liver transplantation.Methods A latex casting mould was developed for the blood supplying to extrahepatic bile duct system in the cadavers.Results The main blood supply to the extrahepatic bile ducts were from the following sources:gastroduodenal artery,the proper hepatic artery and cystic artery.A longitudinal anastomotic chain was found,but 9.6%(3/31) of the casting moulds showed that blood vessels were absent in the middle segments.Conclusion There may be an important relationship between the blood supply to the bile ducts and the complication of the liver transplantation.
