How is an AV fistula formed?
An AV fistula is a connection that’s made between an artery and a vein for dialysis access. A surgical procedure, done in the operating room, is required to stitch together two vessels to create an AV fistula.
Why is AV fistula created for hemodialysis?
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.
Is an AV fistula a catheter?
An AV fistula made by joining an artery and vein in your arm. An AV graft made by using a soft tube to join an artery and vein in your arm. A catheter, a soft tube that is placed in a large vein, usually in your neck.
What artery is used for AV fistula?

How many types of AV fistula are there?
There are 3 basic types of AVF dialysis: Radial Cephalic fistula. Brachial Cephalic. Brachial Basilic Transposition.
When do you need a fistula for dialysis?
They found that AVF creation at least 4 months before starting dialysis was associated with the lowest risk of sepsis and death. The elderly, diabetics and women provide unique subsets of patients with increased risk when starting dialysis.
How do you insert a hemodialysis catheter?
A small incision will be made in the lower neck. The doctor will access the jugular vein in the neck with a needle and pass a small guidewire into the vein. The guidewire will be passed to a larger blood vessel called the vena cava. A second incision will be made in the chest below the first incision.
Which is better fistula or catheter?
If your access is a catheter, it can be connected directly to the dialysis tubes without the use of needles. A fistula should be considered the first choice for your access because it generally lasts longer and has fewer problems such as infections and clotting.
Where is a hemodialysis catheter placed?
If you need hemodialysis right away and you do not have time to wait for a fistula or graft to work, the surgeon can put in a catheter.
