Abstract
To the best of our knowledge, a possible predictive relationship between the systemic coagulation-inflammation index (SCI) and arteriovenous fistula (AVF) failure following AVF creation has not yet been examined. We therefore designed this study to examine the predictive ability of SCI on postoperative early AVF failure in patients undergoing primary radiocephalic AVF operation. A total of 189 patients who underwent primary radiocephalic AVF operation for hemodialysis access were included in this retrospective observational cohort study, and then divided into two groups according to whether AVF failure occurred within the first 3 months after the operation; as failed AVF group (n = 44) and non-failed AVF group (n = 145). The patients' baseline clinical characteristics and laboratory parameters were recorded and then compared between the groups. Patients in failed AVF group were significantly older and had higher smoking rate than those in non-failed AF group. The median values of fibrinogen, platelet-to-lymphocyte ratio and SCI were significantly higher in failed AVF group than in non-failed AVF group. With regards to other clinical characteristics and laboratory parameters, no significant differences were detected between the groups in the univariate analyses. Only age and SCI maintained their significances in the multivariate logistic regression analysis, and were therefore considered as the independent predictors of AVF failure. ROC curve analysis revealed that SCI of 37.9 constituted the optimum cut-off value with 97.7% sensitivity and 94.5% specificity rates for predicting AVF failure. The present study demonstrated for the first time in the literature that SCI significantly and independently predicted early AVF failure following radiocephalic AVF creation.
