Primary Outcome Measures:
  • Number of Patients Who Achieved Hemostatic Efficacy After Surgery [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
    Efficacy at the end of surgery as determined by the investigator and/or the surgeon using the 4 point ordinal scale (Excellent, Good, Moderate or None). Excellent: Achieved hemostatic comparable to non-hemophilic patients. Good: Prolonged time to hemostasis (with somewhat increased bleeding compared to non-hemophilic patients.


Secondary Outcome Measures:
  • Number of Patients Who Achieved Hemostatic Efficacy at Hospital Discharge [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
    Assessment of hemostatic efficacy by the investigator at the day of discharge from the hospital using the 4 point ordinal scale (Excellent, Good, Moderate or None). Excellent: Achieved hemostatic comparable to non-hemophilic patients. Good: Prolonged time to hemostasis (with somewhat increased bleeding compared to non-hemophilic patients.
