BACKGROUND: To explore the trends of venous diameter and brachial artery volume flow (VF) in 12 weeks after arteriovenous fistula (AVF) and the influence of preoperative arterial diameter on this trend. Our goal was to clarify the maturation process within 12 weeks after AVF surgery.
METHODS: Clinical data of 257 patients with end-stage renal disease who had their first radial-cephalic AVF established at our institution from February 1, 2023, to February 1, 2024, were included. The patients were divided into group A (radial artery diameter <1.5 mm), group B (radial artery diameter 1.5-2.0 mm), and group C (radial artery diameter >2.0 mm) according to the preoperative radial artery diameter. After AVF surgery, the artery and vein diameter and brachial artery VF were recorded at 1 day, 2 weeks, 4 weeks, 6 weeks, 8 weeks, 10 weeks, and 12 weeks.
RESULTS: The venous diameter and brachial artery VF of AVF showed an upward trend and increased significantly in 1 day-6 weeks postoperatively (P < 0.05), especially between 1 day and 2 weeks, while no significant difference in the increases at 6-12 weeks. Groups B and C were in line with the above trend, whereas the patients in group A showed best growth in 2-4 weeks postoperatively. The natural maturation rates of AVF in groups B and C were significantly better than that of group A at all postoperative time (P＜0.05).
CONCLUSIONS: The AVF was in a developmentally dominant stage at 6 weeks postoperatively, with 1 day-2 weeks being particularly prominent. The postoperative natural maturation rate of AVF with arteries diameter of <1.5 mm was low; the direct use of such arteries to establish AVF needs careful consideration.
