• . We compared blood loss and hemostasis in pigs which had undergone either orthotopic liver transplantation (OLT) (group A, n= 12) or auxiliary heterotopic partial liver transplantation (APLT) (group B, n= 11). Blood samples were taken at regular intervals during and after the operations. In both groups, nine animals survived longer than 24 h and data from these animals were used for analysis. Median (range) intraoperative blood loss was 825 ml (250–1500 ml) in OLT and 425 ml (300–750) in APLT (P < 0.01). Routine clotting times, as the activated partial thromboplastin time, prothrombin time and thrombin time, snowed no major intraoperative changes in either group. Fibrinogen levels decreased in both groups, but no significant difference was found between the two groups. The only significant difference between group A and B was a more sustained increase in fibrinolytic activity after graft recirculation in group A. Postoperatively, restoration of fibrinogen, antithrombin‐III and α2‐antiplasmin levels was slightly faster in group B, resulting in significantly higher levels during the first day. We conclude that, in this animal model, APLT is associated with significantly lower blood loss and less severe fibrinolytic activity, than OLT. This difference might result from the lack of an anhepatic period and the reduced surgical trauma in auxiliary heterotopic liver transplantation.
