Özet:

Heparin-induced thrombocytopenia (HIT) is a rare but serious prothrombotic adverse effect of heparin treatment. It is induced by platelet-activating antibodies against complexes of platelet factor 4 and heparin. Diagnosis rests on a clinical assessment of disease probability and laboratory testing. Prompt diagnosis of HIT, discontinuation of heparin use, and subsequent treatment with alternative anticoagulant drugs are essential steps to prevent serious complications such as thrombus formation, limb amputation, and death. In this review, we describe the clinical features of HIT and to summarize the data available for its management.
