Haemoadsorption cartridge connected to the machine perfusion for donation after circulatory death porcine liver marginal grafts

Figure 1 Study design. After the slaughter of 7 pigs, the livers were made very marginal with long donor warm ischemia time and cold ischemia time and 4 of them were perfused in a hypothermic machine perfusion (HMP); 3 of them with HMP connected to the filter of the cytokines, Persorb (Sorb) and 2 underwent a standard cycle of HMP (NoSorb). Two livers were stored in the ice box without any preservation treatment (NoTreat). CIT: Cold ischemia time; DWIT: Donor warm ischemia time; HMP: Hypothermic machine perfusion; NoSorb: Hypothermic machine perfusion without the cartridge; NoTreat: No treatment; Sorb: Hypothermic machine perfusion with PerSorb.
