Objective:By color Doppler ultrasound in the case of non-dialysis measurements of brachial artery blood flow to investigate its relationship with dialysis in radial artery-cephalic vein internal fistula. Methods:The blood flow in brachial artery of 60 cases of fistula patients was measured by color Doppler ultrasound,and the test indicators were compared with those after dialysis. Results:In the group,the measurement range of the blood flow of 35 normal dialysis patients was 550~ 950 mL·min - 1 ,average 610 mL·min - 1 ,the test indicators were normal;Complications,such as fistula stenosis and thrombosis,occurred in 20 cases,in which the blood flow was 300 ~ 500 mL·min - 1 ,test indicators were abnor-mal;5 cases of artificial fistula maturation were failed,unable to meet the needs of dialysis,in which the blood flow was below 300 mL·min - 1 . Conclusion:By measuring brachial artery blood flow color Doppler ultrasound can assess blood flow of dialysis,thereby it can monitor the function of the artificial cephalic vein-radial artery internal fistula.%目的：通过彩色多普勒超声在非透析情况下测量肱动脉血流量，探讨其与透析用头静脉-桡动脉人工内瘘功能的关系。方法：对60例内瘘患者用彩色多普勒超声测量肱动脉血流量，与透析后检验指标进行对照分析。结果：本组35例正常透析患者，血流量测量范围550~950 mL·min -1，平均610 mL·min -1，各项检验指标均正常；20例发生内瘘狭窄、血栓等并发症，血流量为300~500 mL·min -1，检验指标出现异常；5例为人工内瘘成熟失败，无法满足透析需要，血流量﹤300 mL·min -1。结论：彩色多普勒超声通过测量肱动脉血流量，可评估透析的血流量，从而监测头静脉-桡动脉人工内瘘的功能。
