Retrospective Review of Arteriovenous Fistula Success Rate in a Multi-ethnic Asian Population:

BackgroundNative vein arteriovenous fistulas (AVFs) are the recommended first-line vascular access in hemodialysis patients. Despite this, AVFs are plagued with unfavorable maturation rates. We conducted a retrospective cohort study to assess the AVF success rate and to identify any significant associating factors.MethodologyDemographic and clinical data of all AVFs created from January 2011 to June 2013 at a single center with a multi-ethnic Asian population, were reviewed. The primary outcome was AVF successfully used for hemodialysis (FUSH) at 6 months. Secondary endpoints were the overall FUSH and actual maturation time of the AVFs. Univariate and multivariate analyses were performed to identify factors associated with AVF success.ResultsA total of 375 fistulas were created during the study period (110 radiocephalic, 176 brachiocephalic, 89 brachiobasilic). The mean age was 59.4 ± 12.6 years and 42.9% were females. Seventy-one percent of patients had diabetes, 32.5% had ischemic heart disease and 10.7...
