Coagulation disorders in children.

  • Approximately 1% of the general population has a mutation in the von Willebrand factor gene.
  • Female carriers of hemophilia A & B have an
    increased risk of bleeding after trauma and medical interventions.12
  • A child with hemophilia may experience
    spontaneous haemarthrosis (bleeding into a joint) two or three times per week.25
  • Bleeding complications may affect around 20% of children who do sports.26

Any of the following situations could indicate a coagulation disorder:

  • Prolonged nosebleeds (epistaxis).
  • Large hematomas from minor injuries.
  • Hematoma following intramuscular vaccination.
  • Heavy menstrual bleeding (menorrhagia).
When discussing bleeding, ask the patient whether he or she has had other symptoms of potential coagulation disorders.

This takes only 5 minutes – better safe than sorry!
