Why do dialysis patients have AV fistula?
A fistula usually allows you to have better, more efficient dialysis than a line, because the blood can flow out quicker, so you get more dialysis in your session. This is important for long term health and survival.
How is dialysis done through a fistula?
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.
Does hemodialysis require a fistula or graft in the arm?
An access is placed by a minor surgery. As a hemodialysis patient, your access is one of the following: A fistula, an access made by joining an artery and vein in your arm. A graft, an access made by using a piece of soft tube to join an artery and vein in your arm.
How soon can you use a dialysis fistula?
Arteriovenous (AV) fistula for hemodialysis Once the fistula is created it’s a natural part of the body. Once the fistula properly matures, it provides an access with good blood flow that can last for decades. It can take weeks to months before the fistula is ready to be used for hemodialysis.
How does hemodialysis work for patients with renal failure?
In hemodialysis, a machine filters wastes, salts and fluid from your blood when your kidneys are no longer healthy enough to do this work adequately. Hemodialysis (he-moe-die-AL-uh-sis) is one way to treat advanced kidney failure and can help you carry on an active life despite failing kidneys.
Can you do dialysis without a fistula?
Central Venous Catheter (CVC) If you need immediate or emergency dialysis or cannot receive and don’t have an AV fistula or graft, you will require a CVC.
How long can a dialysis fistula last?
A fistula will usually last for many years. A fistula usually takes one to four months to “mature” or enlarge before it can be used. If you are already receiving hemodialysis using an AV graft or catheter, ask your doctor about the benefits of a fistula. An AV (artery- vein) graft is the second choice for an access.
What can go wrong with an AV fistula?
The most important complications of fistulae for HD are lymphedema, infection, aneurysm, stenosis, congestive heart failure, steal syndrome, ischemic neuropathy and thrombosis.
What happens if AV fistula fails?
If your AV fistula malfunctions or fails due to the presence of blood clots, your doctors may suggest certain medications depending on the severity of the clots. Some medications can help thin the blood and dissolve blood clots so that the fistula can function again properly.
What is a common side effect of hemodialysis?
A drop in blood pressure is a common side effect of hemodialysis. Low blood pressure may be accompanied by shortness of breath, abdominal cramps, muscle cramps, nausea or vomiting.

What is ultrafiltration in dialysis?
Ultrafiltration is the removal of fluid from a patient and is one of the functions of the kidneys that dialysis treatment replaces. Ultrafiltration occurs when fluid passes across a semipermeable membrane (a membrane that allows some substances to pass through but not others) due to a driving pressure.
What is haemodialysis arm arteriovenous fistula creation?
Haemodialysis arm arteriovenous fistula ( AVF) creation is a procedure performed for haemodialysis access in those with end stage renal failure. It connects an artery to a vein in the arm.
