椎动脉型颈椎病的彩色多普勒超声检测

为探讨超声检测颈椎病合并椎动脉供血不足的价值 ,运用彩色多普勒超声观察了 5 0例椎动脉型颈椎病患者椎动脉的形态结构 ,检测其血流速度、阻力指数、搏动指数和血流量。将测得的各参数进行统计学处理 ,结果发现 ,与对照组相比 ,颈椎病组椎动脉的阻力指数和搏动指数明显增高 (P <0 .0 5 ) ,而峰值流速、舒张末期流速和血流量轻微下降 (P >0 .0 5 ) ,但差异无显著性。以上提示 ,彩色多普勒超声为椎动脉型颈椎病提供了椎动脉形态学及血流动力学改变的依据。

The Values of Color Doppler Ultrasonography in Vertebral Artery Cervical Spondylosis Examination

Aim To study the values of color doppler ultrasonography (CDU) for vertebral artery cervical spondylosis. Methods The changes of structure, velocity (V), blood flow volume (Q), resistance index (RI), and pulsatility index (PI) of 50 cases were studied. 30 healthy subjects were included in the study and served as a control group. Results As compared with the control group, RI and PI were significantly increased (P<0.05) and systolic peak flow velocity (SPV), end-diastolic flow velocity (EDV), Q were slightly reduced(P>0.05) in cervical spondylosis group(P>0.05). Conclusions CDU provide a valuable objective basis on morphological and hemodynamic changes of the vertebral artery cervical spondylosis patients with vertebrobasilar insufficiency (VBI).
