Clinical Trial Summary

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.
