Color Doppler ultrasonography imaging to guide transluminal angioplasty of venous
stenosis. Background The objective of access surveillance is the early recognition of …

Background: Measurement of access blood flow is the preferred noninvasive screening test
for hemodialysis arteriovenous (AV) fistula stenosis. However, performance characteristics …

Percutaneous transluminal angioplasty (PTA) is a possible treatment for stenosis. This study
aimed to verify the impact of a vascular access (VA) surveillance protocol, based on the …

PURPOSE: This report describes intermediate findings from an ongoing prospective
randomized trial comparing the results of percutaneous transluminal angioplasty (PTA) with …

Color flow Doppler provides accurate imaging and access flow volume measurement of the
hemodialysis vascular access. It can readily identify subsets of patients at high risk for future …

Purpose: To examine prospectively the effects of balloon inflation time on the technical
success of balloon angioplasty in dialysis access venous stenosis and on postintervention …

Vascular access (VA) is the lifeline for the hemodialysis patient and the native arterio‐
venous fistula (AVF) is the first‐choice access. Among the different tests used in the VA …
