#4066 EARLY EXPERIENCE OF ENDOVASCULAR CREATION OF ARTERIOVENOUS FISTULA IN SOUTHEAST ASIA

Abstract Background and Aims Creation of native arteriovenous fistulae(AVF) has been traditionally through open surgical technique. Endovascular creation AVF (EndoAVF) shown to be an effective alternative surgery in Europe North America. In Asia, EndoAVF is a novel technique we report our early experience case series 18 patients. Method Between Nov 2021 Aug 2022, ultrasound vein mapping was performed total 39 Eighteen patients were deemed suitable for proceed the procedure. attempted by multidisciplinary team comprising vascular surgeon, interventional radiologists nephrologists. The prospectively followed-up at least 6-months. Baseline demographics, characteristics, unassisted maturation, functional patency freedom from intervention studied. Results Table 1 shows baseline demographics participants.

Two participants (11%) underwent interventions facilitate maturation median time 70 (IQR 49 – 106) days first successful 2-needle cannulation 77 (56 127) days. At 6-months, 8 (50%) EndoAVFs that required further maintain patency, abandoned failure mature despite Conclusion can Southeast Asian population. Further studies with more longer follow-up periods are needed assess long-term outcomes.
