Fistula (Arteriovenous AVF)
Since blood vessels cannot provide sufficient and constant blood flow for dialysis, a method called fistula is used for hemodialysis. Fistula is a short-term procedure that is created by combining an artery with a vein by surgical intervention. The newly created blood vessel combines the properties of the arteries and veins, making the vessel suitable for dialysis.
After the arteriovenous procedure, the diameter of the blood vessel grows enough that a needle can enter within 2-6 weeks and the fistula thickness increases. In this way, a needle is made to the fistula, since it enables a large amount of blood to pass through the extracorporeal blood circuit, allowing effective hemodialysis.
