In patients with critical carotid stenosis and ischemic stroke, it is crucial to determine whether distal hypoperfusion or artery-to-artery embolism is the predominant mechanism. The role of transcranial doppler (TCD) in this setting is vital. We report a patient with fibromuscular dysplasia and recurrent orthostatic transient ischemic attacks where fall in cerebral perfusion was clearly demonstrated by TCD.
在患有严重颈动脉狭窄和缺血性中风的患者中，确定远端灌注不足或动脉到动脉栓塞是否为主要机制至关重要。经颅多普勒（TCD）在这种情况下的作用至关重要。我们报告了一名患有纤维肌发育异常和复发性体位性短暂性脑缺血发作的患者，TCD清楚地显示了其脑灌注下降。
