Intracranial arterial stenosis (IAS) is thought to be responsible for 8% of all ischemic stroke subtypes. The best medical treatment for this condition is still controversial. Transcranial Doppler (TCD) emboli monitoring may help to guide the treatment by measuring the frequency of microembolic signals (MES). We report a case of IAS where TCD emboli monitoring proved useful in establishing the mechanism of stroke by being artery-to-artery emboli and guiding therapy based on the frequent symptoms and number of MES.
颅内动脉狭窄（Intracranial Arterial Stenosis，IAS）被认为是所有缺血性脑卒中亚型的 8%的病因。这种情况下的最佳医疗治疗方法仍存在争议。经颅多普勒（Transcranial Doppler，TCD）栓子监测通过测量微栓子信号（Microembolic Signals，MES）的频率，可能有助于通过测量微栓子信号的频率来指导治疗。我们报告了一例 IAS 病例，TCD 栓子监测通过证实为动脉到动脉栓子的卒中发病机制，并根据频繁的症状和 MES 的数量来指导治疗，从而证明了其在确立发病机制和指导治疗方面的有用性。
