目的：建立椎动脉血流量及血流参数左右差大样本正常值。方法：应用超声多普勒诊断仪检测１０００例健康人双侧椎动脉，用ＳＡＳ统计分析软件计算。结果：正常人椎动脉血流量右侧１３０．４７±５６．１０ｍｌ／ｍｉｎ，左侧１６４．２１±６３．５４ｍｌ／ｍｉｎ，双侧血流量总和２９３．７０±８０．７４ｍｌ／ｍｉｎ；血流参数左右差正常值按男、女分老、中、青三组。结论：椎动脉血流量和血流参数左右差为临床判断椎动脉血流动力学变化提供了有价值的客观依据
Objective: To establish the normal value of large sample difference between the left and right vertebral artery blood flow and blood flow parameters. Methods: The bilateral vertebral arteries of 1000 healthy people were detected by Doppler sonography and calculated by SAS statistical analysis software. Results: The normal blood flow of vertebral artery was 130.47 ± 56.10ml / min on the right side, 164.21 ± 63.54ml / min on the left side, and 293.70 ± 80.74ml / min on both sides. The blood flow parameters About normal difference between male and female points, old, middle and young three groups. Conclusion: The difference between the vertebral artery blood flow and the blood flow parameters provides a valuable objective evidence for the clinical judgment of the hemodynamic changes of the vertebral artery
