The condition and prognosis of ischemic cerebrovascular disease(ICVD)are closely associated w ith the w hole blood coagulation status and the reactivity of antiplatelet agents of patients. Thromboelastography ( TEG ) is a reliable means to detect the w hole blood coagulation and fibrinolytic capacity. Its overal results of the evaluation can be used in the coagulation monitoring, efficacy of antiplatelet therapy, and prognostic evaluation in patients w ith ischemic cerebrovascular disease. In recent years, the detection methods of TEG have been improved continuously. The research reports for its clinical application are gradual y increasing. This article review s the clinical application of TEG in the diagnosis, treatment, and prognostic evaluation in ischemic cerebrovascular disease.
