    Notes: Abstract Changes in arterial blood ketone body ratio (KBR) were investigated in 47 human liver transplantations. Of the 20 grafts preserved with University of Wisconsin (UW) solution, 10 had a cold preservation period of less than 10 h (UWS group) and 10 of more than 10 h (UWL group). In 27 other cases, grafts were preserved with EuroCollins (EC) solution for less than 10 h (EC group). In the EC group, KBR increased over 0.7 within 6 h after reperfusion of the graft in 17 cases (63%) and within 24 h in 7 cases (26%). In the 3 other cases, KBR failed to recover, and these patients underwent retransplantation. In the UW group, KBR recovered within 6 h in 13 cases (65%) and within 24 h in 7 cases (35%). There were no significant differences between the UWS and UWL groups. It is shown that the mitochondrial function of liver grafts preserved with UW solution can be well maintained even after extended preservation periods of more than 10 h.

    Description / Table of Contents: Zusammenfassung Anhand eines tierexperimentellen Modells werden die Folgen operativ veränderter Perfusionsbedingungen auf die Leberfunktion aufgezeigt. Drei Gruppen mit je 5 Versuchstieren (deutsches Hausschwein) werden folgenden Operationen unterzogen: Gruppe 1 erhielt einen portokavalen Shunt. Zusätzlich zu einem portokavalen Shunt wurde Gruppe 2 mit einem venösen Interponat zwischen V cava und Pfortaderstumpf versehen. Bei den Tieren der Gruppe 3 wurde neben den beiden genannten Operationen noch eine Arterialisation des Interponats durchgeführt. Im Verlauf wurden zu definierten Zeitpunkten klinische, laborchemische und histologische Daten erfaßt. Die Tiere der Gruppen 2 und 3 wiesen im Verhalten and ebenfalls hinsichtlich aller erhobener Leberfunktionsparameter normale Werte auf. Die Tiere der Gruppe 1 zeigten in allen genannten Funktionen erheblich schlechtere Ergebnisse. In dieser Arbeit konnte demonstriert werden, daß fur eine normale Leberfunktion die direkte portale Perfusion entbehrlich ist und letztere durch kavalvenöses bzw. arterialisiertes kavalvenoses Blut voll kompensiert werden kann.
    Notes: Summary Using an experimental animal model consequences of operatively changed modes of liver perfusion on hepatic function could be demonstrated. Three groups of 5 animals each (swine) had the following operations: Group I received a portocaval shunt. In group II in addition to the portocaval shunt a vein graft was interposed between the vena cava and the portal vein. In group III an arterialization of this graft was performed in addition to the two operations mentioned above. Follow-up at defined time intervals included clinical, laboratory and histological data. It could be demonstrated that animals in group II and III showed normal parameters as far as behavior and controlled lab data are concerned. Animals of group I had significantly poorer results in all tests. In this study we found that direct portal perfusion was not necessary for a normal liver function and could be fully compensated both by caval venous blood and by arterialized caval venous blood.
