What is the average lifespan of a well-functioning AV fistula?

• A. 1 to 3 years
• B. 3 to 5 years
• C. 5 to 10 years
• D. 10 to 15 years

Answer: (C)

The average lifespan of a well-functioning arteriovenous (AV) fistula is typically between 5 to 10 years. AV fistulas, which are surgically created connections between an artery and a vein, are preferred for hemodialysis access due to their durability and lower complication rates compared to other access types, such as grafts or catheters. A well-maintained AV fistula can function effectively for many years, often allowing patients consistent and reliable access to their bloodstream for dialysis treatments. Factors that contribute to longevity include good vascular health, proper care and maintenance of the fistula, and regular monitoring for any signs of complications. This durability is why 5 to 10 years is considered the correct range for the lifespan of a well-functioning AV fistula.
