What does a fistula for dialysis really look like?

What does a fistula for dialysis really look like?

A fistula: A fistula for dialysis is created by connecting a vein in the arm to an artery and giving it usually 6-8 weeks to mature. A good fistula is anatomically not visible but felt through the thrill and bruit it creates. So you should not be able to know the location of a fistula if it is well done. ...Read more

Dialysis (Definition)

Simple answer is that it is a medical technology used primarily to provide an artificial replacement for lost kidney function in people with renal failure. Hemodialysis remove wastes and excess water from the blood by circulating blood outside the body through an external filter, called a dialyzer. Blood and dialysate flow through in opposite directions and the ...Read more

What does a dialysis fistula actually do?

What does a dialysis fistula actually do?

"short circuit": A patient who is on dialysis needs the machine to clean toxins from the blood that the kidneys usually do. The patient's blood needs to get out of the body, through the machine, and back into the body.

A dialysis fistula is made by sewing a vein to an artery. This short-circuits the blood flow and the vein becomes dilated because it experiences arterial pressures. This can be used for access. ...Read more

Dialysis shunt and dialysis fistula the same?

No: A shunt, or graft, is a piece of synthetic tubular material inserted under the skin that dialysis needles insert directly into.
A fistula is a connection of your own artery to a vein. Needles are then placed into the vein when the wall thickness matures. ...Read more

What is the process of decloting an av fistula for dialysis patients?

What is the process of decloting an av fistula for dialysis patients?

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. ...Read more

How does a fistula work to dialysis patient?

Arterial Diversion: When an artery is connected to a vein, the vein walls thicken and become muscular (due to the new high arterial pressure).
This makes finding the vein easier. More importantly, the large bore needles can be removed and pressure held, with clot forming in the muscular walls, to stop the bleeding. If the veins weren't muscular, putting the needle in and taking it out safely, aren't possible. ...Read more

What does an av fistula for dialysis mean?

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. ...Read more

Should bloodpressure be taken in arm where fistula made for dialysis?

Should bloodpressure be taken in arm where fistula made for dialysis?

No: If you take BP and tighten a cuff above the fistula, clotting can occur and clog the fistula. Distally, there is already a steal of blood flow due to the fistula so you don't want to tighten a cuff there unless there is nowhere else to go. ...Read more

Why is it that if a dialysis patient has a ruptured fistula and is haemorrhaging, you shouldn't place a torniquet proximal to the haemorrhage?

Why is it that if a dialysis patient has a ruptured fistula and is haemorrhaging, you shouldn't place a torniquet proximal to the haemorrhage?

Direct pressure: Hold direct pressure over the leak
try to control without clotting the entire fistula or graft, so that it may be salvaged.
Tourniquet may stop the bleeding if high enough pressure but may clot the fistula and require more extensive repair.
Call 911 and get help and transport. ...Read more

How do physicians de-clot an av fistula for dialysis patients?

How do physicians de-clot an av fistula for dialysis patients?

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. ...Read more

Why do physicians use metal needles to access dialysis fistula?

It is less traumatic: Usually specially-trained nurses or technicians access dialysis fistulas, not physicians. Metal needles are used to help penetrate the skin and the thickened wall of the vein accurately and with minimal trauma. Sometimes blunt needles are used (if a buttonholing technique is being employed). ...Read more

During dialysis why does the subclavian catheter have darker blood than in patients with a fistula?

Venous blood: A subclavian catheter has only venous, deoxygenated blood returning from the body. A fistula contains oxygenated arterial blood coming from the heart. This is the reason for the bright red blood seen in fistulas. ...Read more

For a dialysis, why is the subclavian catheter has darker blood rather than in patient with fistula?

For a dialysis, why is the subclavian catheter has darker blood rather than in patient with fistula?

Catheter vs fistula: An a-v fistula (avf) is a connection between an artery and a vein, that's why its called an a, for artery, v, for vein, fistula. Arterial blood has more oxygen, making it redder, than venous blood. A subclavian catheter has both blood tubes in the vein, where there is less oxygenated blood, as it does not have any arterial inflow. That's why it has darker blood than an avf. ...Read more

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.

Venous Hypertension: The fistula causes increase blood flow through the veins draining the arm. If the veins are blocked or narrowed (both possible because of long term dialysis catheter) the increased pressure causes more fluid to collect in the arm and cause swelling. An interventional radiologist might be able to treat the narrowing with a baloon dilation and stunting. ...Read more

What does a hemo dialysis site look like on your arm?

Lump on skin: Hemodialysis sites look like engorged veins. If they are "fistulas" (artery connected to a vein) the lump on the skin follows the natural pathway of the vein. Over time these can dilate and become aneurysmal. The arterio-venous grafts are basically synthetic / plastic tubes which are placed right under the skin. These you can see and feel. The actual needle puncture sites develop small scabs. ...Read more

I would like help -- how dialysis work and why do we need it?

Dialysis machine: The purpose of a dialysis machine (D) and the artificial kidney (A) used on it is to replace the function of the kidneys of an end stage renal disease kidney patient which do not work. The A filters the blood of the patient removing waste products and water the diseased kidneys of the patient cannot do. This prevents the patient dying of kidney failure. The D does not affect the patient's kidneys. ...Read more

Will dialysis affect my employment?

Possibly: If you are on hemodialysis, then you will have to be at an in center facility three times a week for 3 to 4 hours per session. This form of dilaysis makes it very difficult to maintain a full time job however if you choose to perform peritoneal or home hemodialysis, they you have a better shot of maintaining a full time position. ...Read more

What kind of affect does dialysis have on men?

A lot of effects: While dialysis is essential to survival by replacing kidney function unfortunately there is a price to pay with that. Dialysis patients are anemic (low blood counts) and require medications for that, they have many problems with their calcium and phosphorus level. Patients and especially men mostly can be depressed and they lack sexual desire. They may have weight loss and peripheral nerve damag. ...Read more

How does dialysis work? What is it needed for?

How does dialysis work? What is it needed for?

Removes waste, fluid: Dialysis takes over two important functions of the kidney: removing waste products & removing excess fluid. There are two basic techniques: hemodialysis and peritoneal dialysis. In hemodialysis, blood is removed from the body, circulated through a filter much like an oil filter, and returned to the blood stream. Peritoneal dialysis uses the peritoneal membrane in the abdomen. ...Read more
