Dialysis access fistula revision is a procedure performed when a fistula used for hemodialysis becomes narrowed, blocked, or dysfunctional. The surgery involves revising the access site, either by repairing the existing fistula, creating a new one, or using a graft to restore proper blood flow for dialysis treatments.

Dialysis access fistula revision is essential for ensuring that patients undergoing dialysis have a reliable and functional access site, improving the effectiveness of their treatment and overall health.
