Abstract
- BACKGROUND AND AIMS Doppler Ultrasound (DUS) is a superior tool for the assessment of arteriovenous fistula (AVF) functionality. The aim of the study was to determine the association between morphological and haemodynamic characteristics of the blood vessels with AVF maturation. METHOD The study was prospective that analysed 80 patients with chronic kidney disease (CKD) stage 4/5 and CKD stage 5 on haemodialysis (CKD5D) with newly created radio cephalic AVF. Haemodynamics and morphological evaluation of blood vessels by DUS was performed in all patients. The diameter of the cephalic vein, radial and brachial artery was measured: before creation, on the first day (24-h after creation) and at 4 weeks. The blood flow (BF) rate of AVF was calculated by DUS on day 1, at 4 and 8 weeks. The successful maturation of AVF was defined with BF ≥ 600 mL/min. RESULTS The mean age of the patients was 59.9 ± 13.5 years, of which 46 (57.50%) were males. Successful AVF maturation at 4 weeks was 43.75% and 62.5% at 8 weeks. The results of six adjusted models in multivariate analyses showed BF rate on day 1 was a predictor for AVF maturation at 4 (P CONCLUSION Our study showed that BF rate of AVF on day 1 was a predictor for AVF maturation at 4 and 8 weeks. The diameter of blood vessels and male gender were statistically associated with AVF maturation.
