| 摘 要： | 目的 应用经颅多普勒超声技术和屏气试验评价脑梗死患者在急性期、恢复期的脑血管反应性.方法 脑梗死患者107例,健康对照组43名,分别在急性期(3～5d)、恢复期(6个月左右)通过经颅多普勒超声(TCD)技术和屏气试验观察双侧大脑中动脉血流速度变化,计算呼吸抑制指数(BHI).结果 在急性期,梗死组与对照组比较血流速度减慢,梗死侧更明显,BHI明显低于对照组.恢复期与急性期比较血流速度有所加快(P＞0.05),BHI有所升高,但仍明显低于对照组(P＜0.05);其中82例的BHI值较急性期无显著性变化,25例显著增高.Logistic回归分析显示BHI下降与脑梗死相关(P＜0.05).结论 脑梗死患者在急性期脑血管反应性受到损害,恢复期尽管得到一定程度修复,但是一些患者血管反应性仍损害较明显.

| Abstract: | Objective To explore the cerebrovascular reactivity of the patients with cerebral infarction by transcranial color Doppler ultrasound(TCD) and breath-holding test(BHT) in acute and recovery stages.Methods Forty-three healthy individuals and one hundred and seven ischemic patients were included in this study.TCD was used to record the mean velocity of double side middle cerebral artery(MCA).Breath holding test was performed to record the breath holding time and to calculate breath-holding index(BHI) in acute... |
