Abstract
The anatomical snuff box (ASB) arterio-venous fistula (AVF) has gained increasing attention in recent years as an alternative site for vascular access in hemodialysis patients. One of the challenges in assessing its patency and predicting its long-term outcomes is the evaluation of blood flow characteristics. Color Doppler ultrasound is a non-invasive tool that has shown promise in evaluating vascular access and predicting outcomes for AVF. This article investigates the role of color Doppler assessment in predicting the outcomes of ASB AVFs, including its ability to assess flow patterns, vessel patency, and early detection of complications. The study aims to examine how Doppler parameters correlate with fistula maturity and failure, offering valuable insights for clinical decision-making. Our findings suggest that early Doppler evaluation can significantly aid in predicting the success of ASB AVFs, helping to prevent potential failures and improve patient outcomes.
