Background
Duplex ultrasound of hemodialysis access is frequently encountered in clinical practice. Ultrasound is used for surveillance of access, troubleshooting if there is a problem with dialysis, and procedural planning. The purpose of this exhibit is to review duplex ultrasound of hemodialysis access and apply that knowledge to interventional radiologic procedures.

Educational Goals / Teaching Points
This exhibit aims to review anatomy of fistula, types of fistula and grafts, techniques in imaging acquisition, and ultrasound criteria of dialysis access dysfunction. We also illustrate the spectrum of commonly encountered interventions.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
This exhibit focuses on ultrasound of upper and lower extremity fistula and grafts and their corresponding angiograms.

Conclusion
Duplex sonography is critically important for surveillance, troubleshooting, and planning interventions for hemodialysis fistula and grafts.
