What is an advantage of AV grafts?

AV grafts, or arteriovenous grafts, are a common type of vascular access used for patients requiring dialysis. The major advantage of AV grafts is that they provide a larger surface area for cannulation compared to other vascular access methods, such as AV fistulas. This larger surface area allows for easier insertion of needles and better blood flow rates during dialysis treatment, which is crucial for efficient therapy.

This increased surface area is particularly beneficial for patients with smaller or difficult-to-cannulate veins. Additionally, the structure of the graft enhances the technician's ability to access the blood supply needed for dialysis, promoting a smoother and more effective treatment experience. The other options highlight potential disadvantages or characteristics that do not represent advantages, making this choice stand out as the correct option.
