- Heparin-induced thrombocytopenia (HIT) - acquired, transient, prothrombotic disorder;
- Heparin-Induced Thrombocytopenia;
- alternative anticoagulants for treatment of thrombosis complicating HIT;
- pretest probability of HIT - The “4 T's” scoring system;
- alternative anticoagulants used to treat HIT;
- warfarin (coumarin) anticoagulation - contraindicated during acute HIT;
- natural history of isolated HIT?;
- routine platelet count monitoring for HIT;
- UFH - drug-of-choice for management of cardiac and vascular surgery with previous HIT
This chapter contains sections titled:
What are the clinical features that suggest a diagnosis of HIT?
What laboratory tests are clinically useful for detecting HIT antibodies?
What alternative anticoagulants are efficacious for treatment of thrombosis complicating HIT?
Why is warfarin (coumarin) anticoagulation contraindicated during acute HIT?
What is the natural history of isolated HIT?
Can HIT be prevented?
Should routine platelet count monitoring for HIT be performed in some circumstances?
Is deliberate reexposure to heparin ever warranted in a patient with previous HIT?
