Abstract
The machine perfusion (MP) technique can expand the donor pool for organ transplantation. The MP technique is able to eliminate toxins generated from cells and provide nutrition and oxygen to the tissues via the continuous supply of the preservation perfusate. Furthermore, the organ viability can be evaluated using screening techniques during MP before implantation in a recipient. In this study, the new visualization technique to evaluate the organ conditions of the flow distribution is proposed and discussed using porcine donated livers. This technique is employed the temperature difference of the perfusate for organ preservation to visualized the portal vein flow distributions during machine perfusion. As results, the flow distributions in the liver and the transitions of the temperature at the each measurement points can indicate the organ functions before implantation.
