【摘要】：目的探讨不同频率突发性聋患者的椎-基底动脉血流动力学改变特点。方法以90例突发性聋患者为研究对象,根据听阈曲线类型分为低中频下降组、高频下降组及全频下降组,每组30例,正常对照组30例,各组均行经颅多普勒(transcranial doppler,TCD)检查,探测双侧椎动脉(vertebral artery,VA)、基底动脉(basilar artery,BA),分别记录比较各组收缩期流速(systolic velocity,Vs)、舒张期流速(diastolic velocity,Vd)、脉冲指数(pulsitility index,PI)、阻力指数(resistance index,RI)。结果①低中频组、高频组、全频组突聋患者椎-基底动脉血流异常率分别为63.33%(19/30)、90.0%(27/30)和90.0%(27/30),对照组异常率为0%,高频及全频组患者血流异常率较低中频组高(P0.05);高频组患者VA、BA以高流速检出较多,全频组患者低流速检出较多(P0.05)。②突发性聋患者VA、BA的PI、RI与对照组比较差异无统计学意义(P0.05),高频组VA、BA的Vs、Vd均高于对照组(P0.05),低中频组BA的Vs高于对照组(P0.05)。结论突聋患者尤其是高频、全频听力下降者椎-基底动脉血流动力学异常率明显增加。
[Abstract]:Objective to investigate the characteristics of vertebrobasilar artery hemodynamics in patients with sudden deafness at different frequencies.Methods 90 patients with sudden deafness were divided into three groups according to the type of hearing threshold curve: low intermediate frequency descending group, high frequency descending group and full frequency descending group, 30 cases in each group and 30 cases in normal control group. Transcranial Doppler transcranial doppler TCD was performed in each group.Results 1low intermediate frequency group, high frequency group,The Pi RI of VABA in the patients with sudden deafness was not significantly different from that in the control group. The VsVD of VABA in the high frequency group was higher than that in the control group, and the Vs of BA in the low medium frequency group was higher than that in the control group.Conclusion the abnormal rate of vertebrobasilar artery hemodynamics in patients with sudden deafness, especially in patients with high frequency and full frequency hearing loss, is significantly increased.
