Predictive efficacy of color Doppler in wrist radio-cephalic AV fistula creation: A prospective study.

High rates of early failure and non-maturation remain major challenges in wrist radio-cephalic arteriovenous fistula (RC-AVF) creation for hemodialysis access. Therefore, it is of interest to assess the role of preoperative color Doppler ultrasonography (CDUS) in predicting successful fistula maturation in 80 patients. Radial artery diameter ≥2.0 mm and cephalic vein diameter ≥2.5 mm were significantly associated with maturation (p < 0.05), with CDUS showing 87% sensitivity and 75% specificity. Higher flow volumes also correlated with better outcomes. Preoperative CDUS is a valuable tool that enhances patient selection and improves AVF success rates.
