The hospital records of those patients who underwent primary AVF creation procedures for haemodialysis between December 2010 and September 2013 were included for retrospective analysis. Of 313 patients, 195 (62%) were male and 118 (38%) were female. Mean age was 60 (range 17–90) years. Of the 313 AVF procedures performed, 229 (73%) were created at forearm (radial artery–cephalic vein), and 84 (27%) were created upperarm (antecubital, brachiocephalic, or brachiobasilic procedures). Early AVF failure was found in 61 (19%) patients. According to chi-square test, the incidence of early AVF failure was higher in patients with heart failure and peripheral artery disease (P < 0.001). According to Mann–Whitney U test, the RDW (P = 0.001) and C-reactive protein (P = 0.024) values were higher in patients with early AVF. Our data showed that preoperative RDW is a reliable parameter that can be useful in predicting the early failure of AVF. Copyright © 2015 YEAR Wolters Kluwer Health, Inc. All rights reserved.
