Ultrasound examination of radio-cephalic arteriovenous fistulas was performed 2\u2009weeks post-surgery. Radio-cephalic arteriovenous fistula maturation was defined as successful cannulation of a fistula with two needles, delivery of blood via the access route at a flow rate \u2a7e200\u2009mL\/min for 4\u2009h, and dialysis via fistulae in at least six consecutive sessions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Eighty-two wrist radio-cephalic arteriovenous fistulas were analyzed, of which 13 failed. Cephalic vein diameter &gt;4.285\u2009mm and brachial artery peak systolic velocity &gt;134.75\u2009cm\/s were the best post-operative ultrasound predictors of radio-cephalic arteriovenous fistula maturity ( p\u2009&lt;\u20090.001 and p\u2009=\u20090.011, respectively). Receiver-operating characteristic curve analysis showed that the sensitivity and specificity of predicting radio-cephalic arteriovenous fistula maturation were 88.4% and 92.3% for cephalic vein diameter (area under the curve\u2009=\u20090.939), respectively, and 82.9% and 76.9% for brachial artery peak systolic velocity (area under the curve\u2009=\u20090.830), respectively. All assessments predicted radio-cephalic arteriovenous fistula maturity (post-operative positive predictive values: cephalic vein diameter\u2009=\u200998.4%, brachial artery peak systolic velocity\u2009=\u200995%) much better than radio-cephalic arteriovenous fistula failure (post-operative negative predictive values: cephalic vein diameter\u2009=\u200960%, brachial artery peak systolic velocity\u2009=\u200945.5%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Two weeks after surgery, a new wrist radio-cephalic arteriovenous fistula with a cephalic vein diameter &gt;4.285\u2009mm was considered suitable for dialysis.
