摘　　要：目的联合应用经颅多普勒超声(CDFI)和常规彩色多普勒超声(TCCS)检查评价椎动脉发育不良(VAH)患者对后循环缺血(PCI)的影响。方法选取92例单侧VAH患者,将有眩晕症状的63例作为有症状组,无眩晕症状的29例作为无症状组。分别应用常规彩色多普勒超声、经颅多普勒超声扫查椎动脉的颅外段、颅内段,对比分析有症状组与无症状组发育不良侧椎动脉椎间隙段及颅内段的收缩期峰值流速(PSV),分析发育不良的椎动脉对后循环的血流动力学影响。同时,记录所有单侧VAH患者在不同年龄段发生后循环缺血症状的发生率,对比分析VAH发生后循环缺血与年龄的关系。结果有症状组患者发育不良侧椎动脉的PSV无论是在颅外段还是颅内段均较无症状组降低,有症状组的发育不良侧椎动脉的颅内段PSV明显低于颅外段,差异有统计学意义(P<0.05),年龄20～39岁的共有23例,其中有后循环缺血症状9例,发生率为39.1%;年龄40～84岁的69例,发生率为78.3%,差异有统计学意义(P<0.05)。结论 VAH不仅能引起后循环缺血,而且随着年龄的增长,其后循环缺血症状会加重。Objective Transcranial Doppler and conventional color Doppler ultrasound were used to evaluate the effect of posterior circulation ischemia on patients with vertebral artery dysplasia（ VAH）. Method 92 cases of unilateral VAH were selected,63 cases with vertigo symptoms were treated as symptomatic group,and 29 cases without vertigo were used as asymptomatic group. The extracranial segment and intracranial segment of vertebral artery were scanned with conventional color Doppler ultrasound and transcranial Doppler ultrasound respectively. The symptom group and asymptomatic group were compared and analyzed. The peak systolic velocity（ PSV） of the intervertebral space and the intracranial segment of the vertebral artery was used to analyze the effect of the dysplastic vertebral artery on the hemodynamics of the posterior circulation. At the same time,the incidence of ischemic symptoms after the onset of all unilateral VAH in different age groups was recorded,and the relationship between ischemia and age after the onset of VAH was compared and analyzed.Result The PSV in the symptomatic group was lower than that in the non symptomatic group,both in the extracranial segment and in the intracranial segment. The intracranial segment of the dysplastic lateral vertebral artery in the symptomatic group was significantly lower than that in the extracranial segment,and the difference was statistically significant（ P〈0. 05）. While comparison intracranial and extracranial PSV of dysplastic lateral vertebral artery in asymptomatic group,the difference was not statistically significant（ P〈0. 05）.There were 23 cases of age（ 20 - 39）,including 9 cases of posterior circulation ischemia,the incidence was 39. 1%,and 69 cases of age（ 40 - 84） years,the incidence was 78. 3%,the difference was statistically significant（ P〈0. 05）. Conclusion Hypoplasia of vertebral artery not only causes posterior circulation ischemia,but also increases the symptoms of circulatory ischemia with age.
