OBJECTIVE: The systemic immune inflammation (SII) index has been an excellent prognostic indicator in patients with acute ischemic stroke (AIS). In this study, we assessed the utility of the SII in predicting the prognosis and reperfusion status of patients with AIS who underwent endovascular treatment (EVT).
PATIENTS AND METHODS: 123 consecutive AIS patients were enrolled in our study. The receiver-operating characteristics (ROC) curve was used to determine the cut-off value of SII for predicting unsuccessful cerebral reperfusion. Multivariate logistic regression analysis analyzed the association between SII and unsuccessful reperfusion rate after EVT.
RESULTS: The median value of SII was significantly higher in patients with unsuccessful reperfusion compared to patients with successful reperfusion [2,029 (1,217-2,771) vs. 1,172 (680-2,145) respectively, p=0.003)]. A ROC curve analysis showed that the best cut-off value of SII for predicting unsuccessful reperfusion status was 1,690, with sensitivity and specificity of 71% and 69%, respectively. The area under the curve (AUC) was 0.673 (95% CI; 0.552-0.793). Multivariate analysis demonstrated that SII ≥ 1,690 value was an independent predictor of unsuccessful cerebral reperfusion and unfavorable clinical outcome after EVT (Hazard ratio – H.R.=3.713, 95% CI: 1.281-10.76, p=0.016, HR=2.28, 95% CI: 1.06-4.88, p=0.035, respectively).
CONCLUSIONS: We suggested that SII is a potential indicator to predict the unsuccessful cerebral reperfusion and unfavorable clinical outcome for patients with AIS undergoing EVT.Free PDF Download
