title: [Coagulation factor IX inhibitor in hemophilia B].
abstract: An inhibitor against blood clotting factor IX was observed as a very rare finding in case of an eight year old boy suffering from haemophilia B. By reason of a haemarthros a replacement therapy was successful done using FEIBA (Factor Eight Inhibitor Bypassing Activity). The haemostatic characterization of the inhibitor and its influence by therapy will be presented.
