What is AV Fistula Placement (Arteriovenous fistula)
AV Fistula placement is a surgical procedure to create a connection between a blood vessel that carries blood away from your heart (artery) and a blood vessel that returns blood to your heart (vein). The connection is called a fistula. It is often made in the forearm or upper arm.
You may need this procedure if you are getting hemodialysis treatments for kidney disease. An AV fistula makes your vein larger and stronger over several months. This makes the vein a safe and easy spot to insert the needles that are used for hemodialysis.
