What is an AV Fistula

A Comprehensive Guide on AV Fistula Surgery for Dialysis

What is an AV Fistula? 

An arteriovenous (AV) fistula is a surgical connection made between an artery and a vein. It is commonly created in the arm for patients who require hemodialysis, a treatment for kidney failure. The AV fistula allows for high blood flow, which is essential for effective dialysis. 

How is an AV Fistula Used During Dialysis? 

During dialysis, two needles are inserted into the AV fistula. One needle draws blood from the body to the dialysis machine, where it is filtered and cleaned. The other needle returns the filtered blood to the body. The high blood flow through the AV fistula ensures efficient cleaning of the blood and helps maintain the durability of the fistula. 

When Does AV Fistula Surgery Take Place?

AV fistula surgery is typically performed several months before the patient starts dialysis. This lead time allows the fistula to mature, increasing in size and strength to handle the repeated needle insertions required during dialysis sessions. The maturation period can vary but usually takes 6-12 weeks. 

Are There Alternatives to AV Fistula? 

Yes, there are alternatives to an AV fistula. These include: 

  • AV Graft: A synthetic tube that connects an artery to a vein. It can be used sooner after placement compared to an AV fistula but has a higher risk of infection and clotting. 
  • Central Venous Catheter: A tube placed in a large vein in the neck, chest, or groin. It can be used immediately for dialysis but is not recommended for long-term use due to higher risks of infection and lower blood flow rates.
