Abstract:Objective To investigate the prognostic factors of aneurysmal subarachnoid hemorrhage (aSAH) and the value of neutrophil/lymphocyte ratio (NLR) in the prognosis. Methods The clinical data of 106 patients with aSAH from May 2016 to May 2018 were analyzed retrospectively.According to the results of modified Rankin Scale (mRS) at discharge,the patients were divided into good prognosis group (n=71) and bad prognosis group (n=35).The clinical data of the two groups were compared,and the related indexes with differences in single factor analysis were analyzed by multivariate Logistic regression analysis.The value of NLR in evaluating the short-term prognosis of aSAH patients was analyzed by receiver operating characteristic (ROC) curve. Results Multivariate Logistic regression analysis showed that Hunt-Hess grade (OR=2.136),NLR (OR=1.257),blood glucose (OR=1.364) and neurological complications (OR=3.251) were independent prognostic factors in aSAH patients (P<0.05,P<0.01).ROC curve showed that area under curve (AUC) of NRL was 0.814 (P<0.01),the best cut-off value was 10.92,sensitivity was 80.00%,specificity was 71.82%,and Jordan index was 0.518. Conclusion Hunt-Hess grade,NLR,blood glucose and neurological complications are independent factors affecting the short-term prognosis of aSAH patients,and NLR has a high value in evaluating the short-term prognosis.
