摘　　要：目的分析寰椎椎动脉沟环的X线分型,探讨寰椎动脉沟环对椎动脉血流动力学的影响。方法回顾性分析临床有颈性眩晕症状,并同时做经颅多普勒和颈椎X线正侧位检查的患者,纳入64例有椎动脉沟环者作为实验组,42例没有椎动脉沟环者作为对照组,分析两者的基底动脉和椎动脉的收缩期峰流速(Vs)、舒张末期流速(Vd)、平均血流速度(Vm)、搏动指数(PI)检测结果。将椎动脉沟环分为半环组及全环组,对比两组的血流动力学情况。结果实验组37例(57.8%)基底动脉或椎动脉血流异常;对照组9例(21.4%)基底动脉或椎动脉血流减慢。在平卧中立位,实验组与对照组对比,右椎动脉Vs、Vm,左椎动脉Vs、Vm,基底动脉Vs、Vm,组间差异均有统计学意义(P<0.05);右椎动脉Vd、PI,左椎动脉Vd、PI,基底动脉Vd、PI的两组间相比,差异均无统计学意义(P>0.05)。全环组与半环组的右椎动脉Vs、Vd、Vm、PI,左椎动脉Vs、Vd、Vm、PI,基底动脉Vs、Vd、Vm、PI相比,差异均无统计学意义(P>0.05)。结论椎动脉沟环会使基底动脉、椎动脉血流速度减低,为临床诊断颈性眩晕提供较为客观的资料。Objective To analyze the classification of vertebral artery ditch bridge of the atlas,and to explore the influence of the different type on the hemodynamics of the vertebral artery.Methods A retrospective analysis was performed on patients with clinical symptoms of cervical vertigo,who received TCD and cervical X-ray examination.The 64 patients with vertebral artery ditch bridge were divided into incomplete type and complete type;another 42 healthy people without vertebral artery ditch bridge were selected as the control group.The systolic peak velocity(Vs),diastolic peak velocity(Vd),mean flow velocity(Vm),pulsation index(PI)of the three groups were analyzed by variance analysis.The hemodynamic situation of the incomplete and complete type of patients with vertebral artery ditch bridge was compared.Results In the vertebral artery sulcus ring group,37 cases(abnormal rate 57.8%)had abnormal basilar artery or vertebral artery blood flow;in the control group,the blood flow of the basilar artery or vertebral artery slowed down in 9 cases(abnormal rate 21.4%).In the supine neutral position,the differencesin the right vertebral artery Vs,Vm,the left vertebral artery Vs,Vm,and the basilar artery Vs,Vmwere all statistically significant in comparison of groups with vertebral artery groove ring and without vertebral artery groove ring(P<0.05).But the difference was no statistically significant in terms of the right vertebral artery Vd,PI,the left vertebral artery Vd,PI,and the basilar artery Vd,PI(P>0.05).The differences in the right vertebral arteryVs,Vd,Vm,PI,the left vertebral arteryVs,Vd,Vm,PI,and the basilar arteryVs,Vd,Vm,PI were not statistically significant in comparison of full ring group and half ring group(P>0.05).Conclusion Both the incomplete type and the complete type vertebral artery ditch bridge of the atlas may reduce the vertebral artery blood flow speed,providing more objective data for the clinical diagnosis of cervical vertigo.
