Effect of a Hanging Type Holder in a Perfusion Preservation System for Organ Preservation

Abstract

We have developed a hanging type holder, which consists of parts of (sheet, supports and base) using 3D-CAD and 3D printing system for machine perfusion preservation system, and the perfusion experiment was carried out with pig liver using the developed holder. In the result, the perfusion pressure of hepatic artery (HA) and portal vein (PV) in pig liver with the hanging type holder were lower than that of the flat type holder. In addition, we verified the expandability of HA and PV by the photographs of the liver biopsy after the experiments. These results implied that the hanging type holder in perfusion preservation system was effective for organ preservation.
