AV Fistulas
An arteriovenous (AV) fistula is a surgically-created connection between an artery and a vein. It is generally created around 6 months prior to needing hemodialysis so that the vein can open up, or dilate, under the pressure of the blood coming from the artery, which allows a good blood flow rate for hemodialysis. An AV fistula is most commonly created in the lower forearm or the upper arm above the elbow.
If you are already receiving hemodialysis using an AV graft or catheter, ask your doctor about the potential benefits of an AV fistula.
