Abstract

Background: Arteriovenous fistula (AVF) surgery at the anatomical snuff-box is a technique used to create a vascular access for hemodialysis in patients with end-stage renal failure. This is the most distal location in the upper limb where surgery can be performed with high efficiency [1-3]. The study aims to examine the characteristics of patients, evaluate the results and identify related factors, thereby improving and enhancing the effectiveness of surgery.

Methods: Prospective, cross-sectional study with short-term follow-up of 27 cases undergoing anatomical snuff-box AVF surgery at Hue Central Hospital in 2024.

Results: The mean age was 51.4±17.3 years; 81.5% of patients were male; 74.1% had never undergone dialysis; 88.9% had hypertension; 14.8% had diabetes. The surgical success rate was 88.9%; diabetes was a risk factor for surgical failure; the postoperative resistance index of the afferent artery and venous flow were two factors that helped predict the possibility of surgical failure.

Conclusions: AVF surgery at the anatomical snuff-box is safe and effective, postoperative ultrasound assessment of AVF is necessary.
