WebIntroduction to Fistulas for Hemodialysis. Circulatory access for patients undergoing hemodialysis requires an access method that is durable, resistant to infection, and able to support high volume flow of blood to and from the dialysis machine 1.This access is usually obtained through an indwelling central venous catheter, an arteriovenous fistula, or an … WebA fistula enables haemodialysis to take place. Normal veins used for blood tests are not strong enough for dialysis because blood is pumped through the dialysis machine at high speeds. Somehow, we need to create a ‘stronger’ blood vessel. We do this by connecting a vein to an artery either in the wrist area or upper arm.
