What is an AV Fistula?

An AV fistula refers to a surgically created connection between an artery and a vein. This procedure is primarily performed for the purpose of providing access for hemodialysis in patients with chronic kidney failure. The fistula allows for a higher blood flow rate compared to a standard vein, which is essential for effective dialysis treatment, as it facilitates the removal of waste and excess fluid from the bloodstream.

The creation of an AV fistula typically involves using the patient's own blood vessels, which helps to minimize the risk of rejection and complications associated with synthetic materials. This connection promotes the maturation of the vein, allowing it to grow larger and stronger, which is crucial for long-term use. Properly functioning AV fistulas can last for many years, making them a preferred choice over other forms of vascular access for dialysis.

Understanding the specific characteristics and purpose of an AV fistula is important for healthcare providers, particularly in the management of patients undergoing dialysis, ensuring that they have the needed access for treatment and monitoring for any possible complications that may arise from the procedure itself.
