[Emergency treatment of haemophilia A with factor VIII inhibitors using activated prothrombin complex concentrates (author's transl)].

Severe rectal bleeding in a 6-year-old boy with haemophilia A and factor VIII inhibitors could not be stopped with factor VIII concentrates. But a good effect was achieved with activated prothrombin complex concentrates (fraction FEIBA), given over eight days. Amaurosis occurred as a complication after injection of the first dose, but disappeared completely within several minutes. Tests revealed accelerated intravascular coagulation with increased fibrin monomers and fibrin/fibrinogen degradation products.
