Abstract

Reports on the success of permanent vascular access in elderly HD patients vary considerably. We reviewed the records of 149 patients [62F and 87M] aged 20-89 years old (median 59) who were on hemodialysis for 6-242 (49 median) months, and had undergone 202 vascular access procedures (177 Cimmino-Brescia fistulae and 25 PTFE grafts). Patients were divided into two groups according to the age they started HD. Group A: 48 patients, over 60 years old (range 60-83; median 70) on HD for 43.5, (6-140) months. Group B: 101 patients, under 60 years old, range (15-59) median 46, on HD for 54 (6-242) months. There were no differences between the two groups in terms of gender, primary renal disease, (except polycystic kidney disease), Hct and EPO administration. The initial choice of vascular access, the complications and the technique survival were examined in both groups. Cimmino-Brescia fistulae were used as the first choice of vascular access in all patients except one in group B. PTFE-grafts were the second or third choice in 7/48 (group A) and 15/101 (group B) (p: NS). The only reason for technique failure was vascular thrombosis in both groups (11/48 group A and 31/101 group B p: NS). Other complications were: aneurysms (10/48 and 14/101, p: NS), infections (0/48 and 2/101 p: NS) and edema (0/48 and 6/101, p: NS). Five-year technique survival of the first AV fistula in the two groups was 35% and 45% respectively (log-rank test, p: NS). These findings suggest that: a) A.V. fistula is the first choice of vascular access in aged HD patients; b) There is no difference in vascular access complications across age groups; c) Survival of the first A.V. fistula is independent of age.

Vascular access in elderly patients with end-stage renal disease

“…A single-centre, retrospective analysis of 444 AV fistulae supported that age should not be a limiting factor for creation of an AV fistula [50]. The lack of an age-related effect on primary AV fistula patency rates was also verified in other studies [51][52][53][54]. Other studies, however, supported worse AV fistula patency rates in patients [65 years compared with younger individuals [55][56][57].…”
