摘要
目的:观察椎动脉型颈椎病单侧狭窄时狭窄侧和健侧的高频彩色多普勒声像表现和血流动力学变化。方法:应用彩色多普勒超声诊断仪检测78例椎动脉型颈椎病患者单侧内径≤2.5 mm的椎动脉,观察其形态结构、内径(D)、平均血流速度(TAMX)、阻力指数(RI)和血流量(Q),并与健侧及100例正常组进行对照分析。结果:狭窄侧、健侧和正常组三者之间D、RI、Q均有极显著性差异(P<0.01);狭窄侧和健侧的TAMX有极显著性差异(P<0.01);两者分别和正常组对照TAMX均无统计学差异(P>0.05)。结论:高频彩色多普勒超声对临床评价椎动脉型颈椎病单侧狭窄及健侧血流动力学变化及代偿情况提供了有价值的依据。
Objective. To observe the both changes of blood flow dynamics and Doppler effect in the patients suffering vertebral artery type of cervical spondylopathy with unilateral stenosis of vertebral artery by high frequency color Doppler diagnostic apparatus. Methods. 78 cases of patients suffering vertebral artery type of cervical spondylopathy with unilateral inner diameter ≤2. 5mm were chosen and the morphological changes, inner diameter (D), average velocity of blood flow (TAMX), resistance index (RI) and blood flow volume (Q) of stenostic side were observed and compared with contralateral artery and another 100 normal cases. Results: There were significant differences between three groups in D.RI.Q (P 〈 0.01) and significant difference between stenostic and contralateral artery in TAMX (19 〈 0. 01). There was no significant change of TAMX when normal artery were compared with stenostic and contralateral artery(P〉0.05). Conclusion. The high frequency color Doppler ultrasound technique can provided valuable judgment on the blood flow dynamic changes of the stenostic artery and the compensated capability of the contralateral artery.
