Arteriovenous fistula and nerve conduction velocity in patients on hemodialysis: statistical and electrographic findings.

The aim of this study was to investigate the possible influence of arteriovenous fistula (AVF) on nerve conduction velocity in patients on intermittent hemodialysis and its relevance to the pathogenesis of carpal tunnel syndrome (CTS). The data on 22 patients showed no statistically significant differences in the electrographic parameters considered. This suggests that AVF by the end-to-end method plays no significant part in the alteration of nerve conduction. Possibly radial steal phenomena, which occur with other types of AVF, are at least partly responsible for the reported cases of CTS.
