One patient was switched to a continuous infusion after 48 h of rFVIIa boluses. rFVIIa treatment lasted between 5 and 14 days in four patients, with good or excellent efficacy (total dose, 3.13–9.28 mg/kg). The fifth patient, who underwent surgery for prolapsed haemorrhoids, bled on day 6 and day 10 after the procedure, despite a satisfactory prothrombin time and factor VII coagulant level. The rFVIIa dose regimen was increased after the second bleeding episode, then the bleeding rapidly ceased after this modification to the treatment regimen. The total dose of rFVIIa used was 12.65 mg/kg, and treatment lasted 17 days. Antifibrinolytic treatment was used concomitantly in all five patients. Clinical and biological tolerability was excellent, and no increase in the anti-factor VIII inhibitor titre was observed. These results suggest that rFVIIa prophylaxis is effective in haemophilia A patients with factor VIII inhibitors who are undergoing elective or emergency intestinal surgery. Further studies are required to optimize the dose regimen and treatment period according to the surgical indication and technique. aHaemophilia Centre, University Hospital of Caen, bHaemophilia Centre, University Hospital of Kremlin-Bicêtre, cHaemophilia Centre, University Hospital of Paris-Cochin and dHaemophilia Centre, University Hospital of Toulouse, France.
