Objectives. To define experimentally the efficiency and safety of the hypothermic machine perfusion of the liver grafts with Custodiol HTK preservation solution.
Methods. The study was carried out on five donor organs taken from donors with deceased brain, beating heart and with liver recognized to be non-transplantable according to some factors by the donor team. The apparatus of artificial blood circulation was used as a pump. The circuit of the solution circulation was open with free outflow from the inferior vena cava. Solution perfusion was performed through portal vein only, the intake – from the container with the organ located. The left portal vein was clamped to prevent machine perfusion and continuation of a static cold preservation of the left liver lobe. The intake of effluent from the hepatic veins for a biochemical analysis as well as the biopsy of both liver lobes was performed for efficacy estimation.
Results. It has been established that the machine perfusion leads to more profound liver hypothermia two hours after the beginning of perfusion. The another important aspect is considered as a reliable reduction of cytolytic markers expression maximum for two hours. The machine perfusion contributed to the reliable reduction of AST and LDH from the perfused lobe with respect to the initial value. Wherein the values of AST, LDH and ALT in a static cold preservation lobe have not changed reliably comparing to the initial value. Moreover a double reduction of level of necrosis and apoptosis in the perfused lobe was registered in comparison with a static cold preserved lobe after eleven-hours machine perfusion.
Conclusions. The application of hypothermic machine liver perfusion with Custodiol HTK solution with approximated to physiological flow parameters leads to decrease of AST and ALT levels and lactic acidosis. Moreover it associated with reduction of necrosis and apoptosis of hepatocytes in comparison with a static cold liver preservation.
