Abstract:
We herein describe a new ex-situ machine perfusion device as a "technology spotlight" using a model of donors after circulatory death liver grafts procured from slaughterhouse pigs. Fourteen pig liver grafts were included. The device allowed stable perfusion in both hypothermic (n = 6) and normothermic (n = 8) conditions and no technical failure was observed. During perfusion, perfusate and bile samples were collected to assess liver metabolism and viability. An integrated adsorption device showed efficient removal of inflammatory cytokines during treatment. This preliminary experience represents the starting point for further investigations on the potential clinical benefits of cytokines and other inflammatory mediators adsorption during machine perfusion.
