摘要:
目的 探讨经颅超声多普勒(TCD)屏气试验对健康人群脑血流储备能力的评价。方法 试验组90例健康人，TCD检测双侧大脑中动脉的血流频谱，经过屏气试验，观察试验前后血流速度的变化值。结果 18～39岁脑血流储备能力(CVR)为 (41.44±12.56)%，40～59岁为(36.36±12.15)%，≥60岁为 (33.80±10.12)%，组间比较差异均有统计学意义。结论 健康人群CVR随着年龄的增长而下降；超声多普勒屏气试验评价CVR安全可靠。
Abstract:
Objective To investigate the capacity of cerebrovascular reserve in normal individuals.Methods Ninety cases of normal individuals were included in this study.After TCD routine examination,the mean blood flow velocity in the middle cerebral artery during the eupnea and the end of breathholding were detected with transcranial Dopple.Results the capacity of cerebrovascular reserve in right side MCA was different from left side,and sexual did not correlated to cerebrovascular reserve,but age correlated to it.Conclusion In normal individuals,the capacity of cerebrovascular reserve was change with age.The evaluation of cerebrovascular reserve capacity with breath holding test was safe and effective.
