title: Major orthopaedic surgeries for haemophilia with inhibitors using rFVIIa.
abstract: Between 2000 and 2008, 11 major orthopaedic surgeries for 7 congenital haemophilia patients with inhibitors were performed by the first author as the primary doctor using recombinant activated factor VII (rFVIIa). Orthopaedic surgical treatments were performed for six surgeries for four high-responder haemophilia A patients, three surgeries for two high-responder haemophilia B patients and two surgeries for one low-responder haemophilia B patient. This low-responder patient is allergic to factor IX products, so he usually uses rFVIIa as a haemostatic agent. All of the surgeries were major, such as joint arthroplasty, arthroscopic synovectomy, and a combination of both, and excellent surgical results were achieved. Seven cases were controlled by bolus infusion of rFVIIa, and the other four cases were controlled by combined bolus and continuous infusion of rFVIIa. An anti-fibrolytic agent was used for all cases. There were no thrombogenic adverse effects, only two bleeding episodes. As for haemostatic control, nine surgeries were excellent, one was good and one was fair. This report is the largest clinical report on major orthopaedic surgeries at a single institute. We have concluded that the combination of bolus and continuous infusion of rFVIIa is safe and effective, and more convenient to administer than simple bolus infusion therapy to achieve haemostasis at peri-operative periods. In addition, our data also concurs with the data of several previous reports which showed that orthopaedic surgery for haemophilia patients with inhibitors by means of rFVIIa is safe and effective.
