摘　　要：目的:应用经颅多普勒超声(TCD)探讨老年颈源性眩晕与椎-基底动脉的血流动力学变化的关系。方法:选择行TCD检查的48例颈源性眩晕患者(眩晕组)及同期行TCD检查的36例患者(对照组)纳入研究。记录并分析椎动脉、基底动脉的收缩期峰值流速(Vs)、舒张末期流速(Vd)、搏动指数(PI)及RI。结果:2组椎动脉或基底动脉血流异常情况:眩晕组38例,对照组9例。眩晕组椎动脉及基底动脉Vs、Vd均低于对照组,差异均有统计学意义(均P<0.05);PI及RI也较对照组降低,但差异均无统计学意义(均P>0.05)。结论:颈源性眩晕患者椎动脉或基底动脉存在血流异常,TCD检查为临床医师提供了影像学参考,为治疗提供了理论依据。Objective:To explore the relationship between vertebral-basal artery hemodynamic changes and cervical vertigo in the elderly using transcranial Doppler(TCD).Methods:A total of 48 patients with cervical vertigo who underwent TCD examinations(the vertigo group)and 36 controls(the control group)were included.Vs,Vd,pulsatility index(PI)and resistance index(RI)of the vertebral artery and basilar artery were recorded and analyzed.Results:38 patients in the vertigo group and 9 cases in the control group had abnormal blood flow in the vertebral artery or basilar artery.Vs and Vd of the vertebral artery and basilar artery in patients in the vertigo group were lower than those in the control group(all P<0.05),PI and RI were also lower with no statistically significant differences(all P>0.05).Conclusions:The patients with cervical vertigo have abnormal blood flow in the vertebral artery or basilar artery.TCD examination provides an objective imaging reference and theoretical basis for clinicians.
