Vein Distensibility is Superior to Vein Diameter for Predicting Unassisted Maturation of Arteriovenous Fistulae

A mature arteriovenous fistula (AVF) is the preferred hemodialysis access due to its durability and lower risk of complications. Various factors have been implicated as predictors for maturation, including vein diameter and access type. Vein distensibility, which refers to the ability of the vein to dilate in response to changes in blood flow and pressure, has been proposed as a potential predictor for maturation, but its utility remains poorly studied.
