How is an AVF different from a catheter or a graft?
An AVF is created by connecting (usually in your forearm) one of your own a veins and arteries together. Where as a graft requires the surgical placement of a small flexible tube and a catheter requires the placement of a small tube into a large vein in your neck, chest, or groin. The AVF uses your own anatomy and requires no insertion of a “foreign” substance into your body. Since an AVF uses your own vein and artery, it is less likely to clot or become infected and tend to last longer than catheters or grafts.
