[The problem of factor VIII inhibitors in patients with congenital coagulopathies].

It is reported on a 19-year-old patient with haemophilia A, in whom after a tooth extraction haemorrhages developed which could not be commanded. Factor-VIII-inhibitors could be proved qualitatively and quantitatively. As prospective for the therapy proved to be the administration of activated prothrombin complex preparations (FEIBA). The haemorrhages stopped, the partial thromboplastin time shortened. After three weeks the patient could be dismissed from hospital treatment.
