摘　　要：经颅多普勒超声(transcranial Doppler,TCD)能无创、快速地对脑血流动力学进行检查和监测,被称为脑血管的"听诊器"。目前,TCD不仅用于脑血管痉挛或狭窄等的检查,还被用于脑血管反应性(cerebral vasoreactivity,CVR)和脑血流自动调节(cerebral autoregulation,CA)的研究,从而预测卒中发生风险和预后,评估自主神经功能障碍。本文就TCD评价CVR和CA的临床应用价值进行综述,旨在扩大其应用范围。Trancranial Doppler （TCD） can examine and monitor cerebral circulation dynamics non-invasively and effectively, which has been regarded as the stethoscope of the cerebrovascular diseases. TCD is not only used in cerebrovascular spasm or stenosis, but also in study of cerebral vasoreactivity （CVR） and cerebral autoregulation （CA） in order to predict the risk and prognosis of stroke and evaluate the autonomic nervous dysfunction. This article reviews the application value of TCD in CVR and CA, and tries to widen its application range.
