摘　　要：目的:使用多普勒超声评价颈部旋转相关极限体位对椎动脉血流的影响。方法:对40个健康成人年龄在19~21岁(平均20.2岁),分别在颈部中立位、同侧旋转极限,同侧屈曲旋转极限,同侧后伸旋转极限,对侧旋转极限,对侧屈曲旋转极限,对侧后伸旋转极限,卧位,卧位同侧旋转极限,卧位对侧旋转极限等体位下进行椎动脉的流速,管径多普勒超声测量。测量椎动脉位于颈3~4节段,血流量和总血流量通过计算获得,总血流量为同一体位下双侧椎动脉流量和。对包括椎动脉流速,管径,流量及颈部活动角度等数据进行统计分析。结果:后伸旋转极限体位的总血流量大于立位旋转极限位,屈曲旋转极限位,卧位旋转极限位,差异有统计学意义(P<0.05),而后三者之间差异无统计学意义(P>0.05);与中立位比较,旋转极限位和屈曲旋转极限位时,对侧椎动脉血流量均减少,差异有统计学意义(P<0.05),后二者差异无统计学意义(P>0.05),而旋转极限位同侧椎动脉流速,管径均增加,屈曲旋转极限位同侧仅管径增加,差异有统计学意义(P<0.05),流量差异无统计学意义(P>0.05)。结论:颈部不同的旋转相关极限体位对椎动脉血流产生不同的影响,后伸旋转极限位可能增加椎基底动脉血流量。Objective：To evaluate the effect of cervical rotation-related limit position on vertebral artery blood flow by using tran- scranial Doppler（TCD）. Methods：Transcranial Doppler was used to measure blood flow velocity and artery diameter in the verte- bral arteries of 40 healthy adults aged 19 to 21 years old（mean 20.2 years old）in the positions as follows., neck neutral position, ip- silateral rotation limit,ipsilateral flexion rotational limit, ipsilateral extension of rotation limit, contralateral rotation limit, contra- lateral flexion rotation limit, contralateral extension rotation limit, supine, supine ipsilateral rotation limit, supine contralateral rota- tion limit and so on. The vertebral artery in the cervical 3-4 segment were measured,the blood flow and the total blood flow were obtained by calculation. The total blood flow was the sum of bilateral vertebral artery flow under the same position. The data in- cluding the vertebral artery flow rate, diameter, flow and the activity of neck angle were statistically analyzed. Results.. The total blood flow in posterior rotation limit position was higher than that in the rotation limit position,flexion rotation limit position and supine rotation limit position（P〈0.05） ,and there was no significant difference between the three positions（P〉0.05）. Compared with the neutral position, the contralateral vertebral artery blood flow were reduced in the rotational limit position and flexion limit （P〈0. 05）, and there was no significant difference between the two group（P〉0.05）, while the flow velocity and the diameter of ipsilateral vertebral artery in rotation limit position were both increased, for the ipsilateral vertebral artery in flexion rotation limit position, only its diameter was increased（P〈0.05）, there was no significant difference in the flow velocity（P〉0.05）. Conclusion： The different rotation-related limit positions of the neck have different effects on the blood flow of the vertebral arteries, and theposte
