    Abstract:
    Arthropathy is prevalent in patients with haemophilia and inhibitors and is a major source of pain and disability, significantly reducing quality of life. Recombinant activated factor VII (rFVIIa; NovoSeven is one of the treatments available for acute life-threatening bleeding episodes in haemophilia patients with inhibitors. It has also been used successfully in a range of orthopaedic surgical procedures in these patients. This is a review of published data on elective orthopaedic procedures in haemophilia patients with inhibitors under cover of rFVIIa from January 2002 to November 2006. Articles were retrieved from MEDLINE using specified search parameters. Twelve articles covering a total of 80 orthopaedic procedures were identified. In the vast majority of cases, rFVIIa provided safe and effective haemostatic cover during orthopaedic surgery with no bleeding complications. There was variation in the administered dose, although the majority of patients were treated with 90 mug kg(-1) bolus followed by either continuous infusion or bolus infusion. Of those cases reporting bleeding complications, most were considered to be related to an inadequate amount of rFVIIa. The cumulative experience presented here suggests that rFVIIa is safe and effective for providing adequate haemostatic cover for haemophilia patients with inhibitors undergoing orthopaedic surgery. The optimal dosing regimen and mode of administration has yet to be identified. Further controlled trials are needed to confirm these experiences.
