Effect of the modified RADAR, No-touch, and conventional techniques on arteriovenous fistula outcomes

OBJECTIVE: Low primary patency rates represent a major problem of radiocephalic arteriovenous fistula (RC-AVF). No-touch techniques and radial artery deviation and reimplantation (RADAR) were reported and used in RC-AVF creation. To enhance RC-AVF outcomes, we devised a modified RADAR technique and conducted a retrospective study comparing this approach with no-touch and conventional methods for RC-AVF creation. METHODS: We retrospectively reviewed patients undergoing RC-AVF creation for hemodialysis using either the modified RADAR, no-touch, or conventional technique between January 2023 and December 2024. The primary patency, juxta-anastomotic stenosis, and maturation rates of the three techniques were compared and analyzed. CONCLUSION: The modified RADAR technique for RC-AVF creation resulted in higher primary patency, lower juxta-anastomotic stenosis, and improved maturation rates.
