BACKGROUND: Vascular access patency is of vital importance for patients requiring haemodialysis. This analysis validates potential risk factors and benefits in patients undergoing vascular access procedures.
PATIENTS AND METHODS: Vascular access procedures performed over a two-year period were retrospectively analysed. Clinical data and concomitant medication were retrieved from files as were surgical data following a standardized data capture sheet. Outcome parameters were primary (PP) and secondary patency (SP) as well as freedom from repeated revascularization. Minimal follow-up with functioning access was 679 days.
RESULTS: During the observation period, 244 patients (mean age 62.2 +/- 0.9 years, 60.7 % male patients, 36.1 % pre-emptive, 31.1 % late referral) underwent vascular accesses procedures. PP and SP were 35.6 % and 45.6 %, respectively, at 540 days. Presence of diabetes mellitus was associated with decreased PP (OR: 0.6, 95 %-CI: 0.3 - 1.0) and SP (OR: 0.4, 95 %-CI: 0.2 - 0.7), whereas female gender was associated with lower SP (OR: 0.6, 95 %-CI: 0.3 - 0.9) and freedom from repeated revascularization rates (OR: 0.6, 95 %-CI: 0.3 - 1.0). In contrast, presence of hyperparathyreoidism was associated with higher SP (OR: 1.7, 95 %-CI: 1.0 - 3.0) and freedom from repeated revascularization (OR: 1.7, 95 %-CI: 1.0 - 3.0) rates.
CONCLUSIONS: Haemodialysis access performs worst in patients with diabetes mellitus and in women. The benefit of hyperparathyroidism should be interpreted as hypothesis generating.
