Abstract:
Objective:To explore the relationship between neutrophil to lymphocyte ratio(NLR) and first pass effect (FPE) during mechanical thrombectomy in patients with acute anterior circulation large vessel occlusive stroke.Methods:Four hundred and six patients with acute anterior circulation large vessel occlusive stroke, admitted to and received mechanical thrombectomy in our hospital from January 2018 to June 2021, were chosen in our study. They were divided into FPE group ( n=186) and non-FPE group ( n=220) according to whether the occluded vessels were successfully or completely re-canalized after the first mechanical thrombectomy. The baseline data, clinical characteristics and operation related data were recorded and compared. The factors with P<0.05 in univariate analysis were included in multivariate Logistic regression analysis to identify the independent factors for FPE. The receiver operating characteristic (ROC) curve was plotted to compare the effectiveness of various factors in predicting FPE. Results:Univariate analysis showed that there were significant differences in gender, proportion of different collateral circulation grading, neutrophil count, lymphocyte count, platelet to lymphocyte ratio (PLR), and NLR between the two groups ( P<0.05). As compared with non-FPE group, FPE group had significantly higher ASPECTS scores at admission, significantly shorter time from femoral artery puncture to recanalization, significantly higher proportion of vascular recanalization, statistically higher proportion of patients using balloon guiding catheter, significantly lower ratio of contrast extravasation, significantly lower incidences of spontaneous intracerebral hemorrhage and mortality, and statistically higher rate of good prognosis 90 d after surgery ( P<0.05). The results of multivariate Logistics regression analysis showed that gender ( OR=0.686, 95%CI: 1.131-3.491, P=0.017), ASPECTS scores ( OR=0.143, 95%CI: 0.094-0.220, P<0.001), NLR ( OR=1.722, 95%CI: 1.413-2.098, P<0.001), and PLR ( OR=1.007, 95%CI: 1.003-1.014, P<0.001) were independent factors for FPE. ROC curve results showed that the areas under the curve predicted by gender, ASPECTS scores, PLR, NLR and combination of multiple factors (gender+ASPECTS scores+PLR+NLR) were 0.60, 0.17, 0.71, 0.77 and 0.91, respectively; among them, NLR had the highest efficacy in single-factor prediction for FPE, with cut-off value of 5.86, specificity of 83.3%, and sensitivity of 62.3%. Conclusion:High NLR at admission in patients with acute anterior circulation large vessel occlusive stroke is likely to have FPE failure during mechanical thrombectomy.
