    Abstract:
    The experimental study investigates the resuscitation of livers procured from non heart beating donors by venous systemic oxygen persufflation in a pig transplantation model. In group 1 livers were harvested from donor animals after 60 min of potassium induced cardiac arrest. Livers were then flushed and preserved in 4 degrees C cold University of Wisconsin solution for 4 hrs. Then liver transplantation was performed in recipient animals. Animals of group 2 received the same treatment, but during hypothermic storage we applied venous systemic oxygen gas persufflation (VSOP) via the supra-hepatic vena cava. Livers of group 3 were harvested without warm ischemia and without oxygen treatment during cold ischemic storage and were then transplanted. All recipient animals of group 2 and 3 survived the five day follow-up time. All recipient animals of group 1 died a few hours after liver reperfusion due to circulatory shock or liver failure. The liver quality of group 2 recipient animals was similar to group 3 livers, because serum transaminase levels and blood coagulation test showed no significantly different values between those groups. Our data suggest that livers procured from non heart beating donors after 1 hr of cardiac arrest can be resuscitated and successfully transplanted by therapeutic treatment with VSOP.
