Identification of a potential coagulation disorder.
- 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
- The risk of prolonged bleeding after surgery is
2.5 times higher in carriers than in
non-carriers.12
- Over 75% of bleeds in patients with severe
hemophilia are joint bleeds.23
- A simple interview is useful as a screening tool.19
Any of the following situations could indicate a coagulation disorder:
- Abnormal bleeding after childbirth, circumcision or at menarche.
- Large hematomas resulting from minor injuries or
intramuscular injections.
- Chronic intermittent joint pain.
When discussing surgery, ask the patient whether he or she has had symptoms of potential coagulation disorders.
This takes only 5 minutes – better safe than sorry!
