目的:探讨正常人椎动脉内径及多普勒血流量的参考值范围及其相关因素.方法:B-flow超声观测124例正常人左、右侧椎动脉内径(D)、收缩期峰值流速(PS)、舒张末流度(ED)、阻力指数(RI)、时间平均血流速度(TAMEAN)及多普勒血流量(Q);比较D、PS、ED、TAMEAN、RI及Q在左右侧、性别、年龄与体质量指数(BMI)方面的差异及其相关性.结果:正常人左侧脉D2.99±0.46mm, PS 52.98±13.93 cm/s, ED 16.37±5.89 cm/s, TAMEAN 19.59±5.21cm/s, RI0.69±0.08,Q 85.59±36.18ml/min;右侧椎动脉D2.72±0.35 mm,PS 51.45±11.43 cm/s,ED 15.08±4.84cm/s,TAMEAN 18.69±4.84 cm/s,RI 0.71±0.76,Q67.05±26.28 ml/min.左侧椎动脉D及Q高于右侧,差异有统计学意义(P＜0.05).椎动脉D及Q与性别、年龄及BMI均无相关性.
