Trial Summary
What is the purpose of this trial?Infiltration of a surgically-placed hemodialysis vascular access (HVA) is recognized as a major contributor to the high hospital re-admission rate in dialysis-dependent patients. Three dimensional modeling has been demonstrated as a critical tool for procedurists in preparation for surgical interventions but no such modeling is yet available for dialysis specialists to avoid the common complication of HVA infiltration. Contrast enhanced magnetic resonance angiography (MRA) can be used to generate a three dimensional image data that could render a three dimensional resin-based model of a vascular access.
Eligibility Criteria
This trial is for patients who have a surgically placed hemodialysis access used in the last 90 days or will be used soon. It's not for those whose only hemodialysis accesses have failed and haven't been used for over 90 days.Inclusion Criteria
I have a dialysis access placed by surgery that's been used recently or will be soon.
Exclusion Criteria
My surgical access for hemodialysis has failed and hasn't been used for over 90 days.
Participant Groups
The study tests a new tool: a three-dimensional (3D) printed model of hemodialysis vascular access, created from MRI scans to help avoid infiltration during dialysis procedures.

Experimental Treatment
Active Control
Group I: Intervention armExperimental Treatment1 Intervention
Patients in this arm will have a three-dimensional (3D) printed vascular access model to assist the dialysis technician and nurse in cannulation.
Group II: Control armActive Control1 Intervention
Patients in this arm will have standard of care where they will be annulated by the palpation method by the dialysis technician and nurse.
