Three-dimensional (3D) Printed Hemodialysis Vascular Model for Increased Precision of Cannulation
Brigham and Women's Hospital
Summary
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.
Description
Hemodialysis is the most common treatment for End Stage Renal Disease (ESRD). For an optimal renal replacement therapy, a patent vascular access (VA) is essential. The importance of good vascular access maintenance has been strongly supported by the guidelines (1). Various hinderances render this goal unachievable. A well-known cause of VA failure is access infiltration, which is usually overlooked in clinical practices (2). The calculated economic burden attributable to VA complication is between $16,864 -US$20,961 and more than 50% is due to access infiltration alone (3). Imaging has a pivot…
