Vascular access revision is a procedure to correct or improve a vascular access point, typically used for dialysis patients whose access site has failed or become problematic. This procedure can involve creating a new access site, repairing a damaged graft or fistula, or enhancing an existing site to restore proper blood flow for dialysis.

It is essential for ensuring that patients undergoing hemodialysis have reliable access to their bloodstream, which is critical for effective dialysis treatment and overall health.
