OBJECTIVE: This study identified predictors affecting maturation and patency of autogenous radiocephalic @entity2548 (RCAVFs). METHODS: We retrospectively reviewed the prospectively collected clinical data of all @entity1 who underwent primary RCAVF creation and evaluated the effect of clinical variables and findings of preoperative duplex ultrasound mapping on primary maturation and patency rates of RCAVFs. RESULTS: From August 2008 to December 2010, 383 vascular access procedures were performed in 371 @entity1 ; of these, 331 (86.4%) were autogenous AVFs, 283 (85.5%) were primary first AVFs, and 186 (65.7%) of these were RCAVFs. The primary maturation rate was 88.2% at a mean of 39     24.1  days after the operation. By multiple logistic regression analysis, minimum cephalic vein (CV) diameter >2  mm was an independent predictor of RCAVF maturation (odds ratio, 3.672; 95% confidence interval, 1.394-9.673; P  = .008), which was more easily achieved in @entity7964 @entity1 . During the mean follow-up of 47.2     23.1  months, primary patency of RCAVFs was 80.3% at 1  year and 76.5% at 2  years. A Cox proportional hazard model showed @entity6 was the only independent risk factor of primary patency (hazard ratio, 2.008; 95% confidence interval, 1.022-3.945; P  = .043). @entity7964 @entity1 with a CV diameter >2  mm had significantly higher primary maturation rate and higher primary patency than @entity6 @entity1 with a CV diameter  <=2  mm. CONCLUSIONS: There were different risk factors affecting RCAVF primary maturation and primary patency. A CV with a small-diameter of  <=2  mm combined with @entity6 was an independent risk factor of failure not only of primary maturation but also of primary patency in RCAVF.
