超声测量肱动脉血流量对血液透析桡动脉-头静脉内瘘的监测价值

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550-950mL·min-1，平均610mL·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300-500mL·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﹤300mL·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。

Monitoring Value of Ultrasound Measurements of the Blood Flow in Brachial Artery to Hemodialysis in Radial Artery-Cephalic Vein Internal Fistula

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.
