ABSTRACT
BACKGROUND:
Arteriovenous fistula (AVF) is the most preferred vascular access for hemodialysis patients, and early failure of AVF is one of the most avoidable complications of this procedure. We retrospectively evaluated whether adjuvant systemic heparinization just before arterial manipulation could reduce early failure of primary AVF.METHODS:
Three hundred and fifty-six patients with end-stage renal failure who underwent primary AVF surgery from April 2009 to September 2020 were enrolled in this study. The patients were divided into two groups based on whether they received adjuvant heparinization or not. Patient backgrounds, frequency of early AVF failure, and bleeding events were compared between the two groups. Multivariate Cox regression analysis identified risk factors for early AVF failure.RESULTS:
Early failure of AVF was observed in only 2 of 157 patients (1.2%) in the adjuvant group, and the incident was significantly lower than observed in the non-adjuvant group, i.e., 17 of 199 patients (8.5%) (p = 0.002). Bleeding events were not significantly different between the two groups. Seven of 157 patients (4.5%) in the adjuvant group and 7 of 199 patients (3.5%) in the non-adjuvant group experienced bleeding events (p = 0.785). Female sex, use of steroids, hypoalbuminemia, venous stenosis in pre-surgical evaluation, arterial spasm in the perioperative period, new-onset venous stenosis after AVF anastomosis, technical failure of surgery, no early cannulation after surgery, and non-adjuvant heparinization were related to early AVF failure in the multivariate regression analysis.CONCLUSION:
Adjuvant systemic heparinization therapy just before arterial manipulation reduced early failure of primary AVF without increasing bleeding events.Palavras-chave
