If you have been told by your doctor that you will need hemodialysis because of renal failure, you doctor may suggest create a dialysis fistula for your treatment. Through a dialysis fistula surgery, a dialysis fistula is created to connect an artery directly to a vein. The fistula lets much greater blood flow from the artery to the vein. The vein is becoming larger and stronger. After a few months (3 to 6 months), the fistula completes maturation, which can make inserting of needles for dialysis treatment much easier. This is why a fistula is created.
Dialysis fistula is also called arteriovenous fistula (AV) because of the direct communication between an artery and a vein. The main materials of fistula are Polytetrafluoroethylene (PTFE) and other materials, such as bovine vessels, polyurethane, Dacron, saphenous veins. After the fistula becomes matured, the patients can use the dialysis fistula for dialysis 2 to 5 times a week.
