  • Establishment and Evaluation of Orthotopic Liver Transplantation Without VenoVenous Bypass in Miniature Pigs

    【Abstract】Objective To establish animal model of orthotopic liver transplantation(OLT) in miniature pigs with high standardization, reproducibility and stability. Methods OLTs were performed without venovenous bypass in Bama miniature pigs. The survival rates and the changes of hemodynamics and metabolism were investigated. Results Twenty OLTs were performed between pairs of miniature pigs. The mean operative time and anhepatic phase were (181±25.8) min and (28.4±3.2) min respectively. During the anhepatic phase, dramatic hemodynamics and metabolism changes accompanied hyperkalemia identified. MAP and CVP decreased from (14.59±1.68) kPa and (0.66±0.11) kPa to (5.87±0.91) kPa and (0.27±0.10) kPa respectively, while temperature, pH, BE and HCO3- were significantly reduced (P<0.05) and HR and K+ in serum were remarkable increased. After reperfusion, the disorder of hemodynamics and metabolism described above recovered gradually. 1week survival rate was 90%. Sixteen animals survived more than 2 weeks. AST, ALT and TBIL were significantly increased and reached the peak level on postoperative 1 day. From postoperative 2 day, AST, ALT and TBIL began to decrease and reached postanaesthesia level on postoperative 7 day. Conclusion The animal model of OLT without venovenous bypass in miniature pig, with its high standardization, reproducibility and stability, is an ideal one for series studies related to liver transplantation.
