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 moreSee 2 more doctor answers
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
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 moreSee 1 more doctor answer
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
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 moreSee 4 more doctor answers

I am a dialysis patient for 2 yrs. I lift 5 to 10 pds of weights, is it okay for my av fistula. And what can I take to build muscle?
AVF and weights: The answer to your question about lifting weights being ok for your avf is "yes". You need to speak to your renal dietician about what you can eat to build up muscle. Good luck. ...Read more

Growth for dialysis: A primary arterio-venous fistula ( that means where an artery and a vein have been sutured directly into each other as opposed to an interposition graft) takes some time for the vein to grow larger.The size of the vein is important because it allows the flow requirements of dialysis.This often takes a month or two to happen. ...Read more
Connect Vein&Artery: This is when a vein is surgically connected to an artery (end-to-side anastomosis). This maintains blood flow to the hand while diverting blood into the vein. The vein becomes pressurized to arterial pressure and had much higher blood flow. Over time its size will double and its walls thicken so that it can be accessed for dialysis. Left arm is most often used because it is the non-dominant arm. ...Read moreSee 1 more doctor answer
Permanent w/o repair: An AV fistula, or arterial-venous fistula, is an abnormal connection between an artery & vein that allows high pressure arterial blood to travel into the low pressure venous system. It can be caused by traumatic blood vessel injury or purposely created surgically by a doctor (e.g for dialysis access). An AV fistula is always permanent unless repaired surgically or with covered stenting of vessels. ...Read moreSee 2 more doctor answers
Yes- not practical: It turns out that the first "fistulas" made years ago when dialysis first started were "external" fistulas. They were actually synthetic/plastic tubes connecting an artery to a vein. There were significant problems with bleeding and infections. These "external" fist las are not used today. If someone needs urgent dialysis they get a catheter. For long term dialysis either a fistula or a graft. ...Read moreSee 1 more doctor answer
Needssurgical eval: Clotting of the avf is the major problem facing patients on dialysis. Generally, it needs to be evaluated and declotted rapidly to be salvaged (within 1-2 days) by a vascular surgeon or interventional radiologist. The focus more recently is early prevention to prevent clotting from occuring through close monitoring of blood flows and pressures. ...Read more

Well, : An arteriovenous fistula is a disruption of the normal blood flow pattern. Normally, oxygenated blood flows to the tissue through arteries and capillaries. Following the release of oxygen in the tissues, the blood returns to the heart in veins. An arteriovenous fistula is an abnormal connection of an artery and a vein. The blood bypasses the capillaries and tissues, and returns to the heart. ...Read more
AV Malformation?: Depending on the location, an abnormal communication between arteries and veins can have many different symptoms. The purpose of correction is to alleviate the symptoms. In most cases, the aim is to stop possible deadly bleeding. If this is related to your sudden abdominal pain, then tests should confirm it. If it is related to headaches and one is found, it should corrected immediately. ...Read moreSee 1 more doctor answer
