The article by Goldstein and Gupta1 in the October 2003 issue of the ARCHIVES devoted to aging made for interesting reading. The authors took great efforts to study the utility of artery flow and diameter in patients with end-stage renal disease (ESRD); they state that the radial artery carried sufficient flow to support a shunt or fistula in three quarters of cases in a study of 211 patients with a mean age of 49.8 years. As a geriatrician and nephrologist, I was particularly interested in the data and considered the effect of age on artery flow and utility.
