what is the purpose of a av fistula for dialysis patients? i can't find anything good on the internet to explain this, please add link if you have one

Question

I am dialysis patient. Doing since last 6 years. I had line in my neck n when they remove it got clot. Caz of that my fistula hand is swelled.

Answer 1

High flow: An A-V fistula creates a peripheral region of high blood flow so that a large volume of blood can be removed and returned to the body for the "cleaning" done by the dialysis machine.

Answer 2

Arteriovenous fistul: It is an arteriovenous fistula. It is a surgical connection of an artery and a vein. Once "mature", it is where they insert the needles for the blood to flow to the dialysis machine. It can take 3 months or so from "creation" until it is ready to use.

Answer 3

Your lifeline!: Dialysis access is an entrance way into your bloodstream that lies completely beneath your skin. The av fisutla is usually in your arm, and allows blood to be removed and returned quickly, efficiently, and safely during dialysis or, less commonly, for other procedures requiring frequent access to your circulation. Creating the access portal is a minor surgery connecting an artery to a vein.

Answer 4

Av fistula: connection between artery and vein to allow connection to hemodialysis machine

Answer 5

Thrombolysis or surg: Most can be declotted with clot busters. Some need a surgical thrombectomy.

Answer 6

Open or endo: It can be done with tpa (alteplase) (a high-potency medication to dissolve blood clot) and a rotor-rooter device inserted through a needle stick in the access. I tend to make a small incision to remove the clot with a balloon catheter, then do an angioplasty on the area of stenosis (narrowing) which you usually find in the vein or graft.

Answer 7

Many ways: Dissolve or grind up clot. Can suck clot out. Then treat underlying problem with stent.

Answer 8

Two methods: There are two methods: mechanical or chemical. Occasionally both methods are used. In general, the doctor accesses the av graft or fistula with a needle and places a tube into the graft. He then uses wires and catheters to cross the clot and inject clot busting meds. There are devices he can use that also break up clot. Or, he can open the graft and use special balloons to pull clot out.

Answer 9

Declot: A declot is a procedure to remove clot from a dialysis access and regain function of that access. First, a catheter is placed into the fistula or graft. Next, the physician will use either mechanical (think roto-rooter) or pharmacological (clot dissolver) means to remove the clot (or both). Then, the physician will treat the cause of the clot, which is usually a narrowing or the access.
