ABSTRACT
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 < 0.001). Using a larger needle size had better AVF survival rate (P < 0.05). All other factors had no significant correlation with AVF failure.CONCLUSION:
There were no statistically significant differences in AVF patency with respect to gender, age, blood flow rate, presence of diabetes mellitus or systemic hypertension. A distally placed AVF in the nondominant arm had the best survival rate. Using a larger needle size, specifically 15G during dialysis, was associated with lowest AVF failure.Palavras-chave
