[Bleeding complications in acute myeloblastic leukemia (author's transl)].

: Bleeding is common in acute myeloblastic leukemia (AML). At the time of diagnosis, the danger of bleeding cannot be predicted by laboratory means. However, the following factors represent increased risks: Promyeloblastic leukemia, high blast count, low fibrinogen, low plasminogen. From coagulation studies performed at the time of bleeding complications, the pathomechanism leading to bleeding complications usually cannot be detected. The question whether impairment of production, consumption coagulopathy, or primary fibrinolysis causes the bleeding complications can only be answered by controlling frequently clinical and hemostatic criteria, which include the thrombocytic stystem as well as plasmatic coagulation and fibrinolysis. At the present time, the therapy of bleeding complications in AML is symptomatic. It consists of transfusion with thrombocytes or fresh whole blood, respectively. Coagulation factor concentrates should only be given in combination with Heparin to prevent the deterioration of consumption coagulopathy.
