[Syndrome of chronic intravascular coagulation in the course of chronic myeloid leukemia].

The syndrome of chronic intravascular coagulation occurs very often in the course of malignancies including leukaemias, however, it is not always diagnosed. Two cases are presented of chronic syndrome of intravascular coagulation in the course of chronic myeloid leukaemia; in one patient being in chronic phase and in other patient during blastic phase. In the first case the patient required only causative treatment of the basic disease, in the second case, apart from causative treatment of blastic phase, heparin administration, platelet mass and frozen plasma transfusion were necessary.
