#6792 VASCULAR ACCESS SURVIVAL OUTCOME IN ELDERLY HEMODIALYSIS PATIENTS: A SINGLE-CENTER RETROSPECTIVE STUDY

Abstract Background and Aims Elderly hemodialysis patients usually have lower life patency of vascular access than another age-group. Our center, elderly are the most population patients. Prior to initiate hemodialysis, planning first has been established by patients, nephrologist, surgeon. The canulation technique for arteriovenous fistula (AVFs) determined experienced hemodialysis-nurse patient preferences. aim this study was analyze survival outcome depending on type in elderly. Method collected retrospective data between Jan 1, 2013, December 31,2022. We identified (age ≥65) who in-center first-use our including fistulas, graft, tunnel-catheter. Outcomes were subgroup analysis non-extreme group extreme ≥80) group. A χ2 test, Kaplan-Meier performed. Results Overall number initiated 170: 63 AVFs-first (74% buttonhole cannulation technique), 21 grafts-first 86 tunnel-catheters. Mean accesses higher AVFs (78 months AVFs, 52.5 grafts, 53.3 tunnel-catheter P = 0.012). consistency age 65-80 (80.9 47.3 47.2 0.005). However, mean did not differ >80 (56.3 58.4 56.4 0.98). Conclusion In single center data, highest should be choice would especially
