The corrected distal motor latency along the median nerve in 50 upper limbs with the forearm Cimino-Brescia fistula for haemodialysis, when compared to that of the contralateral limb and the control value, showed no evidence of carpal tunnel syndrome (CTS) ascribed to angioaccess. Haemodialysis-associated CTS seems to be related to the predisposing factors, rather than the haemodynamic effects of the arteriovenous fistula or dialysis.
