Background: Ischemic neuropathy is a major complication in patients undergoing hemodialysis (HD) with arteriovenous (AV) fistula. Objectives: The aim of this study was to investigate the relationship between cubital tunnel syndrome and chronic HD via forearm AV fistula. Methods: All HD patients with forearm AV fistulas, who were referred to the hemodialysis ward of Rasoul-e-Akram and Hasheminejad hospitals from February 2014 to February 2015 and met the inclusion criteria, were enrolled in the study. They were asked about ulnar neuropathy symptoms and were under physical examination and electrophysiological studies for cubital tunnel syndrome at the time of recruitment and 1-year follow-up.
