Conclusions: Pain from AVF is poorly recognized and an under-reported problem. While severe pain resulting in the avoidance of dialysis is rare, it can lead to significant difficulties and ultimate abandonment of AVF. Pain is often suggestive of an underlying anatomical problem.
How long does an AVF last?
AV grafts can be safely used in about two weeks, as no maturation of the vessels is necessary. Grafts have a lifespan of approximately 2 to 3 years but can often last longer.
How does an AVF work?
A fistula (also called an arteriovenous fistula or A-V fistula) is made by joining an artery and a vein under the skin in your arm. When the artery and vein are joined, the pressure inside the vein increases, making the walls of the vein stronger. The stronger vein can then receive the needles used for hemodialysis.

Can kidneys start working again after dialysis?
The good news is that acute kidney failure can often be reversed. The kidneys usually start working again within several weeks to months after the underlying cause has been treated. Dialysis is needed until then.
Are fistulas permanent?
