How long can an AV fistula be used?

An arteriovenous (AV) fistula can indeed be used indefinitely as long as it remains functional and there are no complications. This type of vascular access is typically created for patients undergoing hemodialysis, as it allows for the efficient and effective withdrawal and return of blood during the dialysis process.

The AV fistula is formed by surgically connecting an artery to a vein, which causes the vein to enlarge and mature. Once mature, it is capable of supporting the high-flow blood necessary for dialysis treatment. Many patients can have their AV fistula for many years without the need for replacement, making it one of the most preferred options for vascular access compared to other methods, such as catheters or grafts.

While the AV fistula is meant to last a long time, it is dependent on maintaining its patency and the overall health of the patient. If for any reason the fistula no longer functions effectively—due to thrombosis, infection, or other complications—alternative access methods may be considered. However, as long as the fistula is viable, it can be utilized indefinitely for dialysis.
