The initial rotational thromboelastometry revealed severely prolonged clotting times in all four modalities (clotting times measured by EXTEM, INTEM, FIBTEM and APTEM were 679 s, 879 s, 853 s and 807 s, respectively). Other parameters were unmeasurable due to the severity of the blood clotting disorder.
