椎基底动脉供血不足临床与TCD结果分析

目的：探讨椎基底动脉供血不足病人脑血流动力学改变与临床的相关性，提供临床医生在治疗过程的用药依据。方法：应用经颅彩色多谱勒TCD]检测椎基底动脉供血不足的病人椎基度动脉系统的血流动力学。结果：临床诊断为椎基底动脉供血不足的病人，经TCD检查大多数有异常改变，可表现脑血流速度的变化血流速度增快或减慢]，频谱形态及频谱性质的改变，以及转颈试验时峰值流速的变化。结论：TCD是一种无损伤性检查，简单、快速，可为医生诊断椎基底动脉脉供血不足提供重要的诊断依据，对医生选择用药有实际意义。

Clinical and TCD analysis of vertebrobasilar is chemia

OBJECTIVE: In order to provide evidence for clinical treatment by further exploring the relativity between the clinical symptoms and the cerebrohemodynamic changes of patients with vertebrobasilar ischemia(VBI).METHODS: Hemodynamics of the vertebrobasilar artery system were measured with transcranial doppler (TCD) in 222 patients with VBI.RESULTS: Most patients clinically diagnosed of having VBI have some abnormity: the velocity of the blood flow in brain became faster or slower, the formity and property of the frequency spectrum was changed and the maximal blood flow velocity was also changed as the trans-neck test is being done.CONCLUSION: As a noninvasive and simple but quick examination, TCD can not only provide clinical evidence for diagnosis of VBI, but also guide doctors in how to select medication.
