【Abstract】ObjectiveTo establish the stable model of orthtopic liver transplantation in rats.
MethodsIn the light of Kamada’s method, the donor’s liver was perfused through portal vein before it was harvested,and the anastomosis was modified as continous suture with one suture for the suprahepatic inferior vena cava. Two hundred and ten orthotopic liver transplantations were performed in Wistar male rats according to this method.
ResultsThe mean time of donor operation was 35 min, and that of recipient operation was 51 min. The mean cold preserving time of graft was 60 min.The anhepatic phase was about 17 min 〔(17.6±4.5) min〕. Nineteen rats died during operation. The causes of death included: bleeding of suprahepatic inferior vena cava, infrahepatic vena cava thrombosis, biliary obstruction, portal vein constriction and thrombosis, liver injury, bleeding of left subphrenic vein, infection, excessively deep anesthesia and respiratory failure. The 24hour survival was 91.0%(191/210),and the oneweek survival was 85.2%（179/210）.
ConclusionThrough the modification of the anastomosis of suprahepatic inferior vena cava, the nonhepatic time of the recipients could be shortened,and the complications could be decreased. In this way, the survival of recipient rats after liver transplantation could be increased.
