Application of dual hypothermic oxygenated machine perfusion in ex vivo split liver transplantation / 器官移植

ABSTRACT

The technology of split liver transplantation is becoming increasingly mature with rapid development. During ex vivo splitting, the depletion of intracellular energy sources [such as adenosine triphosphate (ATP)] and other metabolic disorders may lead to cell damage and dysfunction, which will be aggravated by reperfusion injury of liver transplantation, clinically manifested as postoperative complications and transplantation failure. To further improve the quality of donor liver in ex vivo split liver transplantation, research teams at home and abroad apply machine perfusion to enhance the quality of donor liver. In this article, the research progresses worldwide on machine perfusion of donor liver in ex vivo split liver transplantation were reviewed, and the application and prospect of dual hypothermic oxygenated machine perfusion (D-HOPE) in ex vivo split liver transplantation were elucidated, aiming to provide reference for increasing the source of donor liver for ex vivo split liver transplantation and further resolving the current status of donorliver shortage.
