椎动脉型颈椎病患者经颅多普勒超声检测结果分析

Analysis on TCD for the diagnosis of cervical spondylosis of vertebral artery type.

目的探讨经颅多普勒超声(TCD)在椎动脉型颈椎病(CSA)诊断中的应用价值。方法应用TCD对100例CSA患者和100例对照组进行脑血流动力学进行检测,再对TCD检测正常的CSA患者和对照组进行TCD转颈试验,并将检测结果进行分析。结果CSA组TCD常规检测血流异常率为63.0%,对照组为9.0%,两组间血流异常率的差异统计学意义(χ2=63.3,P<0.01);经转颈试验后,CSA组血流异常率为91.9%,对照组为15.4%,两组间血流异常率的差异统计学意义(χ2=65.7,P<0.01)。结论常规TCD检测正常者不能排除临床CSA的诊断,TCD转颈试验能够为常规TCD检测进一步提供血流动力学方面的重要依据。

Objective To evaluate the diagnoses the TCD to cervical spondylosis of vertebral artery type（CSA）. Methods 100 patients with CSA and 100 people in the control group were examined by TCD,the change of blood flow of cerebrovascular （ such as the velocity of blood flow, the form of spectrum, the souffle of blood flow） was analyzed. Results the abnormal rate of blood was 63.0% in patients with CSA and 9. 0% in control group（X^2 =63.3,P 〈0.01）. After neck rotation test, the abnormal rate of blood flow in patients with CSA（91.9% ） was higher than that in control group（ 15.4% ） significantly （X^2 =65.7 ,P 〈0. 01 ）. Conclusions Neck rotation test can improve the precision of diagnosis of CSA.
