Abstract:

Abstract：The common clinical manifestations of heparin-induced thrombocytopenia (HIT) include mild or moderate thrombocytopenia and venous or arterial thromboembolism.Thromboembolism is the most fatal outcome of HIT.Since timely diagnosis and treatment of HIT may reduce the risk of adverse outcomes，it is very important to raise awareness of HIT in the clinicians and improve the diagnostic methods in our country.

Key words: heparin-induced thrombocytopenia, thromboembolism

摘要：

肝素诱导的血小板减少症(HIT)的常见表现包括轻中度血小板减少和静脉或动脉的血栓栓塞，后者是HIT的主要死亡原因。及时诊断和正确治疗HIT可明显降低不良预后的危险。目前我们亟待提高对HIT的认识，改善HIT的诊断方法。
