短暂性脑缺血发作的临床、CT和TCD对比研究

目的：分析短暂性脑缺血发作的临床表现与头颅CT（电子计算机断层摄影术）、经颅多谱勒（TCD）超声检查结果之间的关系。方法：对54例短暂性脑缺血发作患者的临床资料、CT及TCD检查结果进行对比研究。结果：TIA中颈内动脉系统TIA占60％，椎基动脉系统TIA占38．8％，其余占1．2％；CT检查发现脑梗塞12例（22．2％）；TCD检查颈内动脉系统TIA异常率为90％，椎基动脉系统TIA异常率为81％。结论：TCD为诊断TIA提供了颅内动脉血流动力学客观指标，有利于结合临床作出病因诊断。

Contrasting Study on Clinical Observation,Manifestations of CT and TCD Examinations in Transient Ischemic Attack

Objective: To analyze the relationship among clinical features, the manifestutions ofXray computerized tomoariphy(CT) and that of transcranial ampler ultrasonography (TCD)in tranSient ischemic attack (TIA). Metheds: The diagnosis of the disease accorded with thestandards of diagnosing cerebral and vascular diseases established by Chinese gaiety ofNeuroscience. Results:of the total 54 patients with TIA, 60% were clinically diagned as withischedric pathogenesis in internal carotid artery, 38% were in vertebrobasilar artery, and 1.2% were in other parts; By or examinations 12 cases of cerebral infarction were found; Thepositive rate of TIAs in internal carotid artery in TCD examination was 90%, and that invertebrobasilar artery was 81 %. conclusion: TCD provides an objective index for diagnosis ofTIA, especially in understanding the intracranial altery bloodstream dynamics. So, it ishelpful to the etiological diagnosis of TIA.
