What is an AV graft?
An arteriovenous (AV) graft is a deliberate connection between an artery and vein that is created by interposing graft material between them. A decision to choose an AV graft over another type of hemodialysis access is individualized based upon anatomy and life expectancy, among other factors.
How long does a AV graft 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. However, AV grafts can be more troublesome than AV fistulas.
How long does it take for AV graft to mature?
Arteriovenous fistulas can take between 6-12 weeks to mature and arteriovenous grafts can generally be used 2-3 weeks after surgery.
What is AV graft in dialysis?

Can you feel a thrill with a graft?
Once your graft has been placed, you’ll be able to feel it beneath your skin. You will feel a vibration, or thrill if you place your fingers over the graft.

Does AV graft have thrill?
How is AV graft created?
An arteriovenous or AV graft is made when the veins are not suitable for an AV fistula. The AV graft is a form of vascular access which is created by inserting a synthetic tube to connect a vein to an artery. Two dialysis needles are inserted into the AV graft on each hemodialysis treatment.
Can you feel a thrill with an AV graft?
What happens if AV graft fails?
If your access is not working well, it can decrease the amount of fluid and toxin removal your dialysis treatment achieves. This, in turn, can affect your overall health and how you feel. If you suspect there’s a problem with your fistula, notify your dialysis care team right away.
What is AV graft surgery?
AV graft surgery allows blood to flow from your body to the dialysis machine and back into your body after filtering.

Surgeons sometimes use a transplanted animal or human blood vessel.
