Heparin-induced thrombocytopenia and cerebrovasculer thromboembolia

Heparin-lnduced Thrombocytopenia is formed as a result of heparin and platelet- factor 4 complexes and the complex which antibodies interaction against. It threats life by causing artery and venous thromboembolia. It is diagnosed with clinical findings and the laboratory consequences that support clinical findings. When it is diagnosed the heparin therapy must be stopped. Nowadays, there are many drugs used as anticoagulation therapy such as lepirudin, argatroban danaparoid,-bivalurudin and fondaparinux. In this study, we discussed a patient with unstable angina pectoris in whom Heparin-lnduced Thrombocytopenia and cerebrovasculer thromboembolia was developed after heparin was applied.
