title: The effect of age on radiocephalic fistula patency.
abstract: BACKGROUND
  Inferior patency rates for radiocephalic fistulae in the elderly have been reported and may explain the increasing use of prosthetic grafts for vascular access. The aim of this study was to assess whether the patency rates of primary radiocephalic fistulae are affected by age.
  
  
  METHODS
  A retrospective casenote review of 53 consecutive patients undergoing primary fistula formation between 1995 and 1998 under the care of a single consultant vascular surgeon. The setting was a specialist vascular surgical unit where the protocol is to offer all new patients a radiocephalic fistula. Fistula patency was defined as successful use for dialysis.
  
  
  RESULTS
  Cumulative patency rates at 2 years were 60% in patients over 60 years (n=27), and 53% in patients under 60 years (n=26). The higher patency rates in the older age group were not significant on log rank testing (p=0.39).
  
  
  CONCLUSIONS
  Age over 60 years did not influence patency rates of primary radiocephalic fistulae, which should remain the haemodialysis access procedure of choice at all ages.
