There are only a few reports of total hip replacement in patients with hemophilia A and inhibitors. We performed total hip replacement in an 18-year-old adolescent boy who had high inhibitor titers since infancy. Recombinant factor VIIa (NovoSeven) was used as a bypass agent during the surgery. There was no excessive introperative bleeding; however, postsurgical bleeding occurred and was controlled by sequential administration of recombinant factor VIIa and activated prothrombin complex concentrate (FEIBA). This is the first report of this treatment modality in such a major surgery. Sequential bypassing agent therapy can be effective for treating refractory bleeding in hemophilia patients who have high inhibitor titers but require major surgery.
