Arteriovenous fisutla (AVF) is the vascular access of choice for hemodialysis but has a high early failure (eAVFF) rate. eAVFF can be defined as thrombosis/stenosis and Doppler ultrasound (DUS)-based failure-to-mature parameters such as postoperative blood flow (PostQa) < 500 ml/min, AVF-vein diameter (PostVD) < 5 mm, and AVF-vein depth (PostVDepth) ≥ 6 mm. We explored whether common risk factors for eAVFF could predict these eAVFF parameters and venous distensibility: the latter is largely overlooked as a potential eAVFF parameter.
