Study Arms (1)

Dialysis

Patients with hemodialysis-dependent end-stage renal disease and a newly created native arteriovenous fistula

Diagnostic Test: Doppler ultrasound study

Interventions

Transcutaneous Doppler ultrasound (DUS) study was performed at the mid brachial artery to assess diameter, VF and RI, and at the mid segment of the efferent vein to assess the diameter and wall thickness.

Dialysis

Eligibility Criteria

Age18 Years - 95 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

The study will recruit patients with end-stage renal disease eligible for native arteriovenous fistula creation for hemodialysis fulfilling the study's inclusion critera.

You may qualify if:

  • Hemodialysis patients
  • new native arteriovenous fistula (AVF)

You may not qualify if:

  • Patients not eligible for AVF creation
  • Patients with non compensated heart failure New York Heart Association stages 3 and 4
