A New Pig Model of Auxiliary Partial Liver Transplantation Based on Anastomosis with
Intrahepatic Inferior Vena Cava of Recipient

Auxiliary partial orthotopic liver transplantation (APOLT) is a feasible approach to treat patients with fulminant hepatic failure and metabolic liver diseases. It is still necessary to establish a simple and reliable APOLT model using large animals for deep research.Ten healthy male or female domestic pigs, weighing 20- 35 kg, were randomly selected to be either donor group (n=8) or recipient group (n=8). The right liver of donor was used as a graft. After the left lobe of recipient was resected, the anterior wall of the distal intrahepatic inferior vena cava was properly dissected. Endto- side anastomosis was performed between graft suprahepatic inferior vena cava and host distal intrahepatic inferior vena cava. End-to-side anastomosis was performed between the donor and recipient portal veins. After the spleen of recipient was resected, end-to-end anastomosis was made between graft hepatic artery and host splenic artery, and a cannula was inserted into host splenicvein for postoperative portal phlebography. The common bile duct of donor was intubated for external drainage.
