|Abstract:||© 2017 International Society for Hemodialysis Introduction: Arteriovenous fistulas (AVFs) are the preferred form vascular access for hemodialysis (HD), as they have a low rate of complications and durable function. The aim of our investigation was to analyze the factors that might influence the function of AVFs. Methods: Data were taken from the computerized patient record system in the Clinic of Urology and Nephrology, Clinical Center, Kragujevac, Serbia, for a 2-year period. We analyzed patients who had requested re-creation of AVFs as a secondary procedure. During this period 112 patients, 73 (65%) men and 39 (35%) women, had AVF thromboses. All relevant clinical and laboratory parameters that could affect the function and survival of AVF were evaluated. Findings: In univariate logistic regression analysis, statistically significant predictors influencing the duration of the fistula were magnesium (P < 0.001), triglycerides (P = 0.041), smoking (P = 0.001), antiplatelet therapy (P < 0.001), and type of HD (bicarbonate vs. hemodiafiltration) (P < 0.001). In the multiple logistic regression model, high concentrations of magnesium (B = 7434; P < 0.001) and antiplatelet therapy (B - 1.042; P = 0.04) were significantly associated with the length of AVF function. Discussion: After successful establishment of an AVF, there is a compelling need to maintain fistula patency. Factors that affect functioning of the AVFs are presently under intense scrutiny. According to our results, some clinical factors may determine long term fistula duration, such as concentration of the magnesium and antiplatelet therapy.|
