Severe coagulopathies can occur during liver transplantation, particularly
after reperfusion of the grafted liver. Heparin release has been proposed
as one of the factors contributing to this coagulopathy. We have analysed
the thrombelastograph (TEG) traces of 55 patients after reperfusion using
native and heparinase-treated samples. In almost all cases an abnormal
native TEG was improved in vitro by heparinase, demonstrating the presence
of heparin or a heparin-like substance. The heparinase-modified TEG allowed
assessment of the underlying coagulation status, providing a rational guide
to blood component replacement or treatment of fibrinolysis.
