Pediatric Dialysis Fistula or Graft Intervention

There are two types of permanent vascular access for dialysis: arteriovenous (AV) fistula and arteriovenous (AV) graft. A surgeon creates an AV fistula by connecting an artery directly to a vein, most commonly in the forearm. Alternatively, a surgeon creates an AV graft by connecting an artery to a vein using a synthetic tube or graft. Sometimes the blood flow from an AV fistula or AV graft becomes too low due to a narrowing, a blood clot, or the formation of a collateral (accessory) blood vessel that is diverting blood flow. An interventional radiologist can correct these problems with fistula intervention or graft intervention.
