  • Establishment of Swine to Monkey Auxiliary Heterotopic Liver Transplantation Model

    Objective To establish the swine to monkey auxiliary heterotopic liver transplantation model and to summarize surgical points. Methods Five healthy landrace piglets and five rhesus monkeys were adopted to establish the xenogenic auxiliary heterotopic liver transplantation model. In our trail landrace piglets were treated as donor andrhesus monkeys were treated as receptor. Putting the transplanted liver which included right posterior segment and part of right anterior segment into rhesus’ nest and left paracolic sulcus, and then blocking abdominal aorta and inferior vena cava shortly for end-to-side anastomosis in portal vein of transplanted liver and abdominal aorta of receptor, in infra-hepatic vena cava of transplanted liver and inferior vena cava of receptor. Ligation was performed at hepatic artery with no recon-struction. The postoperative situation and survival time of the receptors were observed. Results Four pairs of transplan-tation models were successfully established. The duration of donor liver harvesting, donor liver preparation, occlusion of recipient inferior vena cava, occlusion of abdominal aorta, and liver transplantation were (30±5) min (24-35 min),(40±10) min (31-51 min), (30±6) min (23-36 min), (30±8) min (22-38 min), and (220±80) min (130-310 min), respectively. The blood loss during transplantation was (42±6) mL (35-48 mL). There were no thrombosis of the anas-tomosis and biliary fistula in receptors after operation, but 4 receptors died at 48, 54, 88, and 96 hours after liver transp-lantation respectively. Conclusions Swine to monkey auxiliary heterotopic liver transplantation model has b repea-tability, operation procedure is easy, and transplanted organ of it have good perfusion, which can be available for various kinds of basic and preclinical researches.
