转颈试验对椎动脉型颈椎病患者椎-基底动脉血流速度的影响

Influence of the blood flow velocity on vertebro-basilar of patients with cervical spondylosis of vertebral-basilar type during neck rotation test

目的:探讨转颈试验对椎动脉型颈椎病(CSA)患者椎-基底动脉血流速度的影响。方法:应用TCD对98例CSA患者和86例正常人做常规及转颈试验检查,经枕窗分别检测双侧椎动脉(VA)、基底动脉(BA),记录收缩期峰值血流速度(Vp)、平均血流速(Vm)。结果:CSA组TCD转颈试验阳性率为96%,而正常对照组的阳性率仅为16%,两者比较有显著性差异(P<0.05);CSA组的椎动脉和基底动脉的Vp和Vm转颈前后比较有显著差异(P<0.05);对照组椎动脉和基底动脉的Vp和Vm转颈前后比较无显著差异(P>0.05)。结论:采用转颈试验测定椎基底动脉系统血流速度有助于提高TCD对CSA患者的检出率。

Objective：To investigate the influence of the blood flow velocity on vertebral-basilarartery patients with cervical spondylosis of vertebral-basilartype（CSA） during neck rotation test.Methods：The blood flow velocity of vertebralartety and basilarartery were monitored,and then the indexes such as Vp（velocity of spicke systole phase） and Vm（mean velocity） through routine method and neck rotation test were recorded in 98 patients with CSA,together with 86 healthy people as controls.Results：The detected positive rate was 96% in patients with CSA;the positive rate was 16% in normal group.The measured value of crest value of arterial blood flow rate had significant deviation between patients and normal group（P〈0.05）.The patients group had significant deviation between routine method and neck rotation test（P〈0.05）.The normal group had not significant deviation between routine method and neck rotation test（P〉0.05）.Conclusion：The detected rate of CSA in cervical spondylosis increases by using TCD measure the blood flow velocity on vertebro-basilar of patient with cervical spondylosis of vertebral during neck rotation test.
