Objectives: To investigate the significance of upper-arm cephalic veins (UACVs) in radial-cephalic arteriovenous fistulas (RCAVFs), the medical records of 183 patients who had undergone RCAVF creation were reviewed retrospectively. Methods: The patients were divided into two groups according to the status of the UACV upon preoperative venography: group A of 153 cases (83.6%) with a patent UACV and group B of 30 cases (16.3%) with a stenosed or occluded UACV. The clinical outcomes were compared. Result: RCAVFs in group B had a significantly higher maturation failure rate (26.7% vs. 9.8%, p = 0.009) and lower primary/secondary patency rates (log-rank test, p < 0.0001) than those in the group A. The patients in group B required more frequent endovascular intervention to maintain access function (p = 0.002). The most common stenosis site was a draining vein in group B, in comparison to juxta-anastomosis in group A. In the multivariate analyses, the status of the UACV was an independent predictor of the primary and secondary patency rates of RCAVFs (p < 0.005). Conclusion: UACV patency has a significant impact on clinical outcome for RCAVFs. When planning an RCAVF placement, venous status including the UACV should be considered. © 2012 European Society for Vascular Surgery.
