Objective  To analyze the effects of different perfusion and different superior hepatic vena cava anastomosis methods on the establishment of rat orthotopic liver transplantation model. Methods  Eighty SD rats were randomly grouped with donor group and recipient group with 40 rats in each group. Ten rats in the donor liver acquisition group received abdominal aorta infusion set drip irrigation (1 drop/s); 10 rats received abdominal aorta micro-pump perfusion method (6 mL/min); and then received recipient liver transplantation (corresponding to 10 rats in each group). The donor liver perfusion time and donor liver acquisition time of rats in the 2 groups were collected. HE staining was performed on liver tissues after perfusion and 24 h after liver transplantation. Ten rats in the recipient liver transplantation group received continuous anastomosis, and 10 rats received tension-reducing half-needle anastomosis. We collected the anastomosis time of superior and inferior hepatic vena cava, the time of anhepatic stage and the incidence of postoperative complications of the recipient. Results  Contrasted with abdominal aorta infusion group, the perfusion time and acquisition time of donor liver were shorter in the abdominal aorta micro-pump perfusion group (P＜0.05). HE staining showed that the morphology of hepatocytes, portal vein and bile duct in the abdominal aorta micro-pump perfusion group did not change obviously, only a few lymphocytes infiltrated. Contrasted with continuous anastomosis group, the anastomosis time, anhepatic stage of the superior hepatic vena cava, incidences of postoperative anastomotic bleeding and incomplete perfusion of donor liver in the reduced tension half-needle anastomosis group were shorter or lower (P＜0.05). Conclusions  Compared with abdominal aorta infusion set drip method, the quality of donor liver was improved by abdominal aorta micropump perfusion. Compared with continuous anastomosis method, the tension-reducing half-needle anastomosis can shorten the suture time of superior hepatic vena cava and anhepatic stage, and the incidence of anastomotic bleeding was reduced.
