Abstract:
Objective To investigate the effect of auxiliary heterotopic partial liver transplantation in treating acute ischemic liver failure. Methods Auxiliary heterotopic partial liver transplantation was performed on pigs.The pigs were divided into two groups.Group I: The host′ liver was preserved in situ, liver artery was ligated, portal vein was constricted,and donor patial right liver was transplanted under the right lobe of the liver of the host.Portal venous blood supply was constructed only, and arterial blood supply was not constructed .Group B:Except both arterial blood supply and portal venous blood supply of the donor liver were constructed, and the other operative procedures were as the same as in Group A. The living condition, liver function, blood supply, pathology and bile secretion of the donor liver were observed. Results The survival rates in Group B before and after operation were higher than that in Group A .Serum bilirubin(SB) after the operation was higher than that before the operation in Group A, but showed no change in Group B.After the operation, SB in Group A was higher than that in Group B. In Group A, the donor liver didn't secret bile,and hepatocytes were necrosis.In Group B, the bile secretion and blood supply of donor liver were good,and hepatocyte of the donor liver were alive and proliferating actively.The hosts' liver was necrosis obviously in both groups. Conclusions Hosts' liver artery ligation and portal vein constriction can result in acute ischemic liver failure.Auxiliary heterotopic partial liver transplantation is effective in correcting liver failure.The good arterial blood supply must be constructed in the donor liver to get good donor liver quality.
