We report a case of 49 years old man with hepatocellular carcinoma treated by hepatic transplantation. In the early post-trasplant period severe hepatic dysfunction was detected. Because of the possible vascular origin of the graft lesion, an angiography procedure was performed and hepatic artery trombosis was identified cholangiography through a T tube showed a large biliary cavity. We analyze the biliary tract reconstruction after liver transplantation, its risk factors and the management.
