Blood and dialysate flow through in opposite directions and the ...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 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

Is an av fistula permanent or temporary?

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 more

Can a person have an external av fistula?

Can a person have an external av fistula?

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 more

Is it possible for a failed av fistula be reactivated?

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

What happens to your circulation when you have an av fistula?

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

What does it mean to have av fistula in left arm?

What does it mean to have av fistula in left arm?

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 more
