[Bleeding in haemophilia during massive treatment with anti-haemophilic globulin (author's transl)].

After a traffic accident, causing intracranial haemorrhage in a 15-year-old boy with moderately severe haemophilia A, severe bleeding sequelae could not be prevented despite satisfactory substitution with lyophilized antihaemophilic globulin. The bleeding was probably due to a platelet abnormality and not due to an inhibitor. The bleedings were brought under control by freshly prepared cryoprecipitate of the patient's own blood group.
