Triplex Ultrasound Evaluation of Late Failure Hemodialysis Access Fistulae
Triplex ultrasound, the integration of B-mode, color Doppler imaging and quantitative pulsed-wave Doppler analysis has become the gold
standard for initial evaluation of dysfunctional hemodialysis access grafts and fistulae. This article focuses on its use in assessing
autogenous arteriovenous fistulae (AVFs) that have failed after at least three months of successful use.
