Treatment for vWD
Cryoprecipitate (vWF) + DDAVP (release vWF)
Vitamin K deficiency - labs
Prolonged PT, deficient factors 2, 7, 9, 10, C, S
Treatment for vitamin K deficiency
Normal liver fxn – vitamin K supplements
Liver disease or acute hemorrhage – FFP
Hereditary hemorrhagic telangiectasia - gene deficiency
Endoglin (CD 105)
Function of antithrombin 3
Serine protease - inhibits thrombin activation
AT3 requires what?
Heparin
AT3 deficiency causes increased risk of _____
Clotting (via thrombin activation)
AT3 deficiency - presentation
Recurrent LE thrombophlebitis, DVT, leg ulcers, PE
AT3 deficiency - treatment
Refractory?
Anticoagulants (heparin)
AT3 replacement
Protein C/S deficiency - treatment
Warfarin
Factor V Leiden - risk?
Treatment?
Thromboembolism
No episodes = monitor, etc.
Prior episode(s) = lifelong anticoagulation
Prothrombin 20210
Risk?
G-A mutation, causing increased prothrombin activity
Thrombosis
Common occurrences w/ antiphospholipid syndrome
- Thromboembolism
- Miscarriage
- Thrombocytopenia
- Cerebral ischemia/stroke
- UBOs on MRI
Diagnosis of antiphospholipid syndrome (3)
- Prolonged PTT
- No correction using normal plasma
- Neutralization w/ excess phospholipid
Specific diagnostic test for antiphospholipid syndrome
Dilute Russell viper venom time (DRVVT)
Treatment for antiphospholipid syndrome
Hx of thromboembolism –> lifelong anticoagulation
