椎动脉型颈椎病患者前屈牵引治疗前后的血流动力学差异

The Hemodynamic Changes of Cervical Spondylosis(CSA) of Vertebral Artery Type Patients after the Front-traction

目的:观察前屈牵引治疗前后椎动脉型颈椎病患者的椎动脉血流动力学变化。方法:对50例椎动脉型颈椎病患者进行颈椎前屈牵引,利用彩色多普勒超声观察治疗前后椎动脉内径、收缩期最高流速(PSV)、舒张末期流速(EDV)、时间平均流速(TAV)、阻力指数(RI)、搏动指数(PI)。结果:50例椎动脉型颈椎病患者治疗后两侧椎动脉内径及血流各项指数均较治疗前有显著改善(P<0.05)。结论:前屈牵引治疗椎动脉型颈椎病可改善椎动脉的内径及血流速度。

Objective： To observe the hemodynamic change after the treatment of the front-traction for cervical spondylosis （CSA） of Artery type patients. Methods：Fifty cases of CSA of artery type accept the cervical vertebral front-traction. The inside diameter change, peak systolic velocity （PSV）, the end-diastolic velocity （EDV）, time average velocity （TAV）, resistance index（RI） and pulse index（PI） were evaluated by color Doppler ultrasound at the beginning and the end of the treatment. Resuits： The inside diameters, the PSV, EDV, TAV, RI and PI have been significantly improved （ P〈0.05 ）. Conclusion.. Fronttraction treatment can enlarge the inside diameter of the vertebral artery and speed it＇s blood flow.
