title: Management of oral bleedings with recombinant factor VIIa in children with haemophilia A and inhibitor.
abstract: Dental extraction in patients with haemophilia A and high-titre inhibitor is always a high-risk procedure, which often presents a lot of problems associated with bleeding. Prothrombin complex concentrates or recombinant activated factor VII (rFVIIa) has been used to control bleeding. rFVIIa was administered to five boys with severe haemophilia A complicated with inhibitor, who underwent seven dental extractions. The age of the patients ranged between 8 and 13 years (median 10 years). The concentrate was administered in doses of 90-100 microg kg(-1) body weight. Duration in the therapy and intervals between rFVIIa doses depended on the severity of bleeding. rFVIIa was proven to be highly effective and no side-effects of the product were observed.
