[Thromboelastography--an instrument for the researcher or clinician?]

Thromboelastography is a method which is used experimentally since 1948. Since the end of the eighties it is experiencing a certain revival also in clinical medicine. The submitted case-record presents this technique as a very useful aid in the differential diagnosis of postoperative haemorrhagic conditions in cardiosurgery. Its application can facilitate aimed treatment of some typical disorders of haemocoagulation.
