What is the difference between a dialysis fistula and graft?
The fistula resists clotting and infection. An AV graft (sometimes called a bridge graft) is an indirect connection between the artery and vein, most commonly a plastic tube is used, but donated cadaver arteries or veins can also be used.
What is fistula graft?
a fistula, which is made by joining together an artery and vein to make a bigger high-flow blood vessel. a graft, in which a soft plastic tube is placed between an artery and a vein, creating an artificial high-flow blood vessel.
How long does a dialysis graft last?
The long loop gives the dialysis nurses space to access the graft. 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 is fistula surgery done for dialysis?
An AV fistula is how patients are connected to a dialysis machine. A nurse starts your dialysis treatment by inserting two needles into the AV fistula. One needle removes the blood and sends it to the machine, where it is filtered. The second needle allows the blood to be safely returned to the body.
What are the disadvantages of fistula?
The main disadvantages of having an AV fistula can be:
- If you need dialysis right away, you will need a temporary access that can be used while your AV fistula is healing and maturing.
- Healing can sometimes take longer than expected, or the access may fail to mature.
Which is better graft or fistula?
Fistulas Last Longer. If a graft is well cared for, it may last for several years, but a healthy AV fistula is still more durable. (ii) Because it requires less maintenance, fistulas usually present a better long-term option.
Can AV fistula be removed?

What is the dialysis with a shunt?
Dialysis shunts.: A shunt is a term for the connection that shunts blood from an artery to a vein, bypassing the microscopic network in the tissues that normally connect them. This allows a high blood flow access for pulling blood from the body to the dialysis filter.

Is dialysis vascular?
A vascular access is a hemodialysis patient’s lifeline. A vascular access makes life-saving hemodialysis treatments possible. Hemodialysis is a treatment for kidney failure that uses a machine to send the patient’s blood through a filter, called a dialyzer, outside the body.
