Arteriovenous fistula (AVF) blood flow was evaluated in 32 dialysis patients using a pulsed Doppler velocimeter with two dominant features: a range-gated time system and a double transducer probe. With the proposed apparatus, the observation angle between the ultrasound beam and the vessel axis was known. In radial AVF, blood flow was 728 +/- 53 ml/min and was negatively correlated with the age of the AVF (r = -0.62; p less than 0.01). In brachial AVF, blood flow was 778 +/- 152 ml/min. In bovine heterograft AVF, blood flow was 1,225 +/- 125 ml/min. In the overall population, a negative relationship was observed between the diameter of the fistula and the blood flow velocity (r = -0.57; p less than 0.01). The study describes an accurate noninvasive method for the determination of fistula blood flow in dialysis patients, which may be helpful in the follow-up of the regional hemodynamics of this vascular access.
使用具有两个主要特征的脉冲多普勒测速仪对32例透析患者的动静脉内瘘（AVF）血流量进行了评估：距离选通时间系统和双换能器探头。使用该仪器时，超声束与血管轴之间的观察角度是已知的。在桡动脉AVF中，血流量为728±53 ml/min，且与AVF的年龄呈负相关（r = -0.62；p<0.01）。在肱动脉AVF中，血流量为778±152 ml/min。在牛异种移植AVF中，血流量为1225±125 ml/min。在总体人群中，观察到内瘘直径与血流速度之间呈负相关（r = -0.57；p<0.01）。该研究描述了一种准确的非侵入性方法，用于测定透析患者的内瘘血流量，这可能有助于对这种血管通路的局部血流动力学进行随访。
