Also called: AV graft, arteriovenous graft
An AV graft, short for arteriovenous graft, shares similarities with a fistula. It involves the creation of a subcutaneous connection between an artery and a vein. However, in the case of a graft, this connection is facilitated using artificial tubing. The tubing, which resembles a soft, plastic-like tube with a diameter of approximately half an inch, is typically constructed from materials like Teflon® or Gore-Tex®. Alternatively, transplanted animal or human vessels may serve as grafts to bridge an artery and vein. These grafts are commonly positioned in the arm, although placement in the thigh is also an option.
Unlike fistulas, grafts do not necessitate an extended period to mature since they don’t require enlargement before usage. In most instances, a graft can be employed approximately two to six weeks after its placement. However, grafts, being constructed from external materials, are more prone to issues like clotting and infections compared to fistulas. Additionally, they may not have the same longevity as fistulas and could necessitate repair or replacement on an annual basis.
