Overview

The aim of this study is to provide an overview of the possible applications of DUS during the maturation and postoperative follow-up of vascular access, with particular emphasis to establish a relationship between doppler Ultrasound parameters including: 1. Flow volume. 2. Outflow vein diameter. 3. Outflow vein depth. 4. Resistive index.

Conditions

Arteriovenous Fistula

Interventions

doppler ultrasoundDEVICE

a 7.5 MHz ultrasound (US) linear probe is needed, grey-scale ultrasound and Color Doppler and a minimum display facility of the Doppler velocity spectrum for blood flow calculation are mandatory tools.
