摘要 应用脑血管功能检测仪,对60例正常人和68例短暂性脑缺血发作(TIA)患者的脑血管血流动力学参数进行检测。结果显示:(1)TIA组颈总动脉平均流速、最大流速和最小流速及平均流量均明显低于健康对照组(P<0.01)。(2)TIA组右侧颈总动脉平均流速及平均流量低于左侧(P<0.05)。(3)TIA组颈总动脉外周阻力、特性阻抗及脉搏波波速a明显高于对照组,差异均有非常显著意义(P<0.01)。结果说明TIA的发病和转归与脑血管血流动力学改变密切相关。 The cerebrovascular blood flow dynamic indexes in 60 healthy persons and 68 patients with transient ischemic attack (TI A) were detected using cerebrovascular function detector. Results :1. The mean maximum and minimum flow velocities and mean flow quantities of the TIA group were lower than those of the control group (P<0. 01). 2. The mean flow velocities and the mean flow quantities of right common carotid arteries were lower than those of the left ones in the TIA group(P<0. 05). 3. The peripheral vascular resistances,characteristic impedances and the pulse velocity of common carotid arteries of the TIA group were higher than those of the control group with significant differences(P<0. 01). The results indicated that the onset and prognosis of TIA were closely associated with the changes of cerebrovascular blood flow dynamics.
