经颅多普勒对动脉硬化患者颈椎旋转手法治疗的安全性评价

目的：采用经颅多普勒评价动脉硬化患者行颈椎旋转手法的安全性。方法：选取208例动脉硬化患者纳入动脉硬化组,同期选取50例经检查无明显动脉狭窄、硬化斑块及高血压病史的志愿者纳入对照组。分别采用经颅多普勒测定2组患者颈椎中立位、左右旋转45°时椎动脉、基底动脉的收缩期血流速度、舒张末期血流速度、平均流速及搏动指数等参数。结果：颈椎中立位时2组患者双侧椎动脉血流参数、左旋颈时右侧椎动脉血流参数、右旋颈时左侧椎动脉血流参数及颈椎中立位和左右旋颈时基底动脉血流参数比较,差异无统计学意义;左侧旋颈时对照组左侧椎动脉的收缩期血流速度、舒张末期血流速度、平均流速大于动脉硬化组（t=5.944,P=0.000;t=6.571,P=0.000;t=6.665,P=0.000）,搏动指数小于动脉硬化组（t=4.802,P=0.001）;右侧旋颈时对照组右侧椎动脉的收缩期血流速度、舒张末期血流速度、平均流速大于动脉硬化组（t=4.122,P=0.001;t=4.221,P=0.000;t=11.320,P=0.000）,搏动指数小于动脉硬化组（t=2.249,P=0.001）。结论：颈椎旋转手法能改变动脉硬化患者椎动脉的血流参数,而经颅多普勒能够准确反映这些变化,因而可用于颈椎手法前对伴有动脉硬化的患者进行筛查,以减少由于椎动脉血流改变而引起的临床不良事件。

Safety evaluation on the cervical rotatory manipulation for the arteriosclerosis patients through transcranial doppler

Objective:To evaluate the safety of cervical rotatory manipulation for the arteriosclerosis patients through transcranial doppler(TCD).Methods:Two hundred and eight arteriosclerosis patients were selected and enrolled into the arteriosclerosis group,at the same period,50 volunteers without obvious arteriostenosis,atherosclerotic plaque and history of hypertension were selected and enrolled into the control group.The parameters as peak systolic velocity(Vs),end diastolic velocity(Vd),mean velocity(Vm)and pul...
