The Arteriovenous (AV) graft
When the most common method access, the arteriovenous (AV) fistula, cannot be made, the arteriovenous (AV) graft is a suitable substitute.
An arteriovenous graft is a strong artificial tube inserted by a surgeon underneath the skin of your forearm, upper arm or thigh. One end of the tube connects to one of your arteries, and the other end connects to one of your veins (in the same limb). The graft may be straight or in the shape of a horseshoe. The surgeon will decide whether to use your arm or leg for the arteriovenous graft. The decision depends on many factors including the size and condition of your veins and arteries. There is a higher risk for infection and clotting with an arteriovenous graft than with an arteriovenous fistula
