当患者之症状,提示颈内动脉分布区TIA 时,常进行脑血管造影,以冀发现颈动脉狭窄或闭塞的证据。有人认为某些临床表现伴随阳性血管造影结果的机会较高,如血管杂音的存在、视网膜症状的出现及短暂性发作,均有助于临床诊断。在本研究中,作者研究了半球症状的性质是否有助于诊断。 When the patient’s symptoms, prompted the distribution of internal carotid artery TIA, cerebral angiography often, in order to find evidence of carotid artery stenosis or occlusion. Some people think that some of the clinical manifestations of positive angiography with a higher chance of occurrence, such as the presence of vascular murmur, the emergence of retinal symptoms and transient attacks are helpful in clinical diagnosis. In the present study, the authors investigated whether the properties of hemispheric symptoms contribute to diagnosis.
