An ultrasound-guided no incision banding method for the treatment of arteriovenous fistula high-flow in hemodialysis

Objective High-flow vascular access is one of the serious complications in the maturation and subsequent use of arteriovenous fistula (AVF). We adopted a novel surgical approach named no incision limited ligation indwelling needle assisted- revision (NILLINR) to treat high-flow of the hemodialysis vascular access and ascertained the outcomes by regular follow-up visits. Methods This is a retrospective study. 26 hemodialysis patients with symptomatic high-flow access (access flow > 1500 mL/min) were treated with the novel banding method without incision between June 2018 and October 2020. The flow of the brachial artery before and after the restriction was measured by experienced clinicians by using the duplex Doppler ultrasound (DUS). All 26 patients were followed up for up to 1 year. Meanwhile, the brachial artery flow was recorded at 6 months and 1 year after restriction. Results Of all 26 patients included in this study, the mean access flow volume decreased from 2196.2 & PLUSMN; 416.9 mL/min (mean & PLUSMN; SD) to 679.2 & PLUSMN; 67.1 mL/min immediately after the operation. During the follow-up, the volume flow of the brachial artery was still within the restricted range at 6 months (mean & PLUSMN; SD, 720.2 & PLUSMN; 164.7 mL/min) and 1 year (mean & PLUSMN; SD, 713.9 & PLUSMN; 173.8 mL/min) after the operation. Meanwhile, the mean duration of the operation is 8.5 & PLUSMN; 3.3 min, and there is no bleeding or rupture. Conclusion This novel no-incision limited ligation indwelling needle-assisted revision is a safe, effective, and time-saving option to treat high-flow access.

Automated summary

A novel surgical approach named NILLINR was used to treat high-flow vascular access in hemodialysis patients. The study included 26 patients who showed a significant decrease in blood flow volume after the operation and continued to maintain an acceptable range at 6 months and 1 year follow-up. The procedure was safe, effective, and time-saving with no complications.
