A multicentre analysis of the outcome of arteriovenous fistula in maintenance haemodialysis

Introduction: Arteriovenous fistulas (AVF) are the preferred choice for vascular access in hemodialysis. We aim to identify factors that may contribute to AVF failure. Methods: Data regarding AVF survival were collected from 441 patients. All AVFs were either radial or brachial, of the end‐to‐side variety. Parameters studied were age, gender, diabetes mellitus, hypertension prior to end‐stage kidney disease (ESKD), site of fistula, blood flow rate, venous pressure, dialysis vintage and frequency, needle gauge used during dialysis, year of fistula creation, and details of fistula failure. Findings: The 6‐month, 1‐year and 2‐year AVF survival rates were 98.41%, 95.01%, and 89.57%. Failure rates were 17.2%, 5.5%, 26.8%, and 14.4% for dominant radial, non‐dominant radial, dominant brachial and non‐dominant brachial respectively (P
