Role of Color Doppler Ultrasonography in Assessment of Vascular Access Surveillance in Hemodialysis Patients.

Role of Color Doppler Ultrasonography in Assessment of Vascular Access Surveillance in Hemodialysis Patients.

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.

Inclusion Criteria:

• ESRD patients on dialysis with heamodialysis vascular access with adult age group (18 years and above).

Exclusion Criteria:

• Patients with chronically occluded vascular access with failed surgical or interventional attempts.
