摘要
目的研究国内不同年龄段正常成人颅底动脉多普勒信号检出情况和各动脉的血流速度参考值,及血流速度与年龄、性别的相关性。方法利用经颅多普勒超声(TCD)仪检测1500名某社区正常成年居民,记录颅内血管的各参数指标,按年龄和性别分组,对结果进行统计分析。结果大脑前、中、后动脉的检出率随着年龄的增长逐渐降低,各年龄组男女间检出率均有差异;颅内血管平均血流速度随着年龄的增长逐渐降低,各年龄组女性脑血流速度均高于男性;搏动指数(PI)随着年龄的增加逐渐增加,各年龄组男女间PI值无差异。结论正常成人颅底动脉多普勒信号检出率和平均血流速度随年龄、性别规律变化。此结果为临床脑动脉TCD检测提供了评价参考依据。
Objective To study the rates of receiving doppler signal, flow velocity of cerebral artery and the relationship between flow velocity,age and gender in normal adults in China. Methods A total of 1500 normal residents at the community level in Guangdong province were examined, using transcranial doppler. Data was gathered and analyzed. Results With the increase of age, the rate of receiving signal in cerebral artery gradually decreased. Difference between males and females was noticed. Mean velocity of cerebral artery decreased in both genders but the velocity was faster in females than in males and the pulsate index increased without difference. Conclusion The rates of receiving signal and the flow velocity of cerebral artery were related to age and gender and the findings from this study offered criterion for clinical transcranial doppler.
