Dialysis is a lifesaving procedure that artificially removes waste products and excess fluid from the blood when the kidneys are no longer able to function. This treatment is crucial for individuals with advanced kidney disease and is often necessary for those waiting for a kidney transplant.
A key aspect of effective dialysis is establishing proper dialysis access, which allows blood to flow from the body into the dialysis machine and back. There are several dialysis vascular access methods, including arteriovenous (AV) grafts and fistulas, each designed to ensure patients receive the best possible care.

Dialysis access is a critical component of kidney disease treatment, as it effectively removes waste products and excess fluids from the blood. Two primary methods for establishing this access are arteriovenous (AV) grafts and arteriovenous fistulas. While both methods connect an artery and a vein, they differ significantly in their construction, longevity, and suitability for patients.
An arteriovenous graft is a surgically created connection that involves using a synthetic tube to link an artery directly to a vein. This type of access is typically employed in patients whose veins are unsuitable for a fistula due to vascular conditions or prior access history. An AVG generally provides more immediate access, making it an appealing choice for individuals who require urgent or substantial renal replacement therapy. However, one of the drawbacks of using a graft is its longevity; it typically only lasts two to three years before it needs to be replaced.
Due to its synthetic nature, an AVG may also have a higher infection risk than a fistula. While AVGs can be essential for patients with challenging vascular systems, they require careful management to ensure their effectiveness.
An arteriovenous fistula is formed by connecting an artery directly to a vein using the patient's own blood vessels. This connection enables the vessel to enlarge and strengthen over time, facilitating a more robust blood flow suitable for dialysis. The advantage of a fistula is its longevity; when properly matured and maintained, it can last many years—sometimes more than a decade—making it the preferred choice for chronic dialysis patients.
The maturation process of a fistula typically takes several weeks to months, during which the vessel must develop adequately for dialysis. While waiting for maturation, patients may use other forms of access, such as an AVG, if needed urgently. Because an AVF uses the patient’s own tissues, the risk of infection is significantly lower compared to AVG procedures.
Yes! There are several different dialysis fistula types, with the two most common being radiocephalic and brachiocephalic. These refer to the location where the artery and vein are connected in the arm or wrist. Your doctor will determine which type is most suitable for your specific situation.
Choosing the right dialysis access method depends on various factors, including your medical history, the conditions of your veins and arteries, and the urgency of your dialysis needs. One of our specialists will assess your situation through a physical examination and imaging studies to determine the most suitable option. After reviewing your condition and treatment goals, they can explain the pros and cons of each approach, helping you make an informed decision.
The cost of dialysis treatment can vary significantly based on multiple factors, such as the type of dialysis access method, the frequency of treatment, and individual insurance coverage. It's important to discuss potential costs with your healthcare provider and insurance company to better understand your financial responsibilities.
