What is the purpose of using an AV fistula in hemodialysis?

The primary purpose of using an arteriovenous (AV) fistula in hemodialysis is to provide reliable and long-term access to the bloodstream. An AV fistula is a surgical connection made between an artery and a vein, typically in the arm. This connection enhances blood flow and allows for effective and efficient dialysis treatment.

Using an AV fistula is beneficial because it tends to have a longer lifespan compared to other forms of access, such as temporary catheters or AV grafts. This durability minimizes the need for repeated procedures to create access points, reduces the risk of complications such as infections, and allows patients to undergo regular hemodialysis sessions over an extended period. Overall, the creation of an AV fistula is a critical step in ensuring that patients with kidney failure receive consistent and effective treatment.
