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 hemorrhage
- postoperative bleeding
Other diagnostic factors
- gastrointestinal bleeding
- history of repeat blood transfusions
- joint bleeding (hemarthrosis)
- hematuria
- central nervous system bleeding
Risk factors
- positive family history
- consanguineous relationships
Diagnostic tests
1st tests to order
- CBC
- 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)
Tests to avoid
- bleeding time test
Tests 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 analyzer (e.g., PFA-100)
Treatment algorithm
VWD type unknown with bleeding
all types VWD with severe bleeding uncontrolled by other VWD-specific therapies
all types VWD with severe bleeding or before invasive procedures where sustained elevation of VWF levels is necessary: nonpregnant
minor bleeding or minor invasive procedures involving mucous membranes: nonpregnant
minor bleeding or minor invasive procedures not involving mucous membranes: nonpregnant
all types VWD: pregnant
all types VWD with heavy menstrual bleeding
all types VWD with significant chronic or recurrent bleeding
