What is known as an AV Graft in dialysis?

An AV Graft, or arteriovenous graft, is a type of access point created for dialysis. It is used in patients who require long-term dialysis treatment and are not suitable candidates for a fistula due to factors such as poor vascular anatomy. An AV graft is made by surgically connecting an artery and a vein with a synthetic tube, which allows for repeated access to the bloodstream for hemodialysis.

The use of an AV graft enables higher blood flow rates than a traditional fistula and is typically placed in the arm or leg. It is important in the context of dialysis because it provides a reliable and durable means of access necessary for the procedure, allowing for efficient removal of waste products from the blood.

Although the term "dialysis fistula" refers to a different method of vascular access that connects an artery directly to a vein, it is not classified as a graft. The other options, such as a Port-a-cath and an IVC filter, serve entirely different purposes in medical treatment and do not pertain to the direct provision of dialysis access. Thus, referring specifically to the context of dialysis access, the term "dialysis graft" accurately describes the AV Graft.
