What is the primary goal of an AV fistula?

The primary goal of creating an arteriovenous (AV) fistula is to establish a reliable site for hemodialysis access. An AV fistula is surgically formed by connecting an artery to a vein, which enhances blood flow in the vein and thickens its walls over time, making it suitable for repeated needle insertions needed for dialysis. This access point is crucial for patients with chronic kidney disease who require hemodialysis, as it allows for efficient removal of waste products from the blood and electrolyte management.

While improving blood flow may be a beneficial outcome of the fistula, the central purpose remains its role in providing a durable and effective way to access the bloodstream for dialysis treatment. Other options like preventing blood clots and reducing blood pressure are related to vascular health but do not encompass the primary intent of creating an AV fistula.
