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<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<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.
