Prognostic Factors for Arteriovenous Fistula Maturation

We noted a successful overall maturation rate of 72% at our institution when veins at least 2.5 mm in diameter were used. Our sole negative significant predictor for fistula maturation was BMI greater than 29.5. Therefore, in our experience, age, sex, and fistula location should not be used to preclude patients with a vein diameter of at least 2.5 mm from consideration for AV fistula creation.
