Summary

Definition

History and exam

Key diagnostic factors

  • family history of VWD and bleeding
  • easy and excessive bruising
  • bleeding from trauma or minor wounds
  • mucosal bleeding (e.g., epistaxis, gum bleeding)
  • heavy menstrual bleeding (HMB)
  • postpartum haemorrhage
  • post-operative bleeding

Diagnostic investigations

1st investigations to order

  • FBC
  • prothrombin time (PT)
  • activated partial thromboplastin time (aPTT)
  • von Willebrand factor (VWF) antigen (VWF:Ag)
  • von Willebrand factor (VWF) platelet-binding activity assay (VWF:GPIbM, VWF:GPIbR, or VWF:RCo)
  • factor VIII (FVIII) coagulant activity assay (FVIII:C)

Investigations to consider

  • fibrinogen
  • thrombin time
  • von Willebrand factor (VWF) multimer analysis
  • von Willebrand factor (VWF) collagen binding assay (VWF:CB)
  • genetic testing (for type 2B or 2N VWD variants)
  • low-dose ristocetin-induced platelet agglutination (RIPA) mixing studies
  • von Willebrand factor (VWF) FVIII binding assay (VWF:FVIIIB)
  • VWF propeptide assay (VWFpp/VWF:Ag)
  • platelet function analyser (e.g., PFA-100)
