Updates of heterotopic auxiliary liver transplantation with portal vein arterialization

Abstract

In recent years, liver transplantation donor shortage as one of world medical problems is paid more attention by domestic and overseas scholars. In view of that, heterotopic auxiliary liver transplantation emerges which transplants the whole or some parts of a donor liver outside the original liver position on the condition that some parts or the whole of the original liver were retained. As for the liver transplantation with poor conditions on portal vein, reconstruction of portal vein has become an aporia. Based on this, some scholars put forward the theory–arterialization of portal vein(PVA), namely a method to increase arterial blood supply or replace portal vein blood perfusion of liver by establishing some pathes among artery and portal vein or its branches. The research background and current situation of heterotopic auxiliary liver transplantation with portal vein arterialization, the transplanting position of donor liver, vessel reconstruction, dynamics mechanism after reconstruction and liver regene-ration are summarized in this review.
