The clinical value of inflammation-related factors in prediction of delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage

Abstract

Objective To investigate the clinical value of inflammation-related factors [white blood cell count,erythrocyte sedimentation rate (ESR),and C-reactive protein] in predicting delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage.Methods The aneurysmal subarachnoid hemorrhage in 217 cases according to whether the occurrence of delayed cerebral ischemia were divided into 2 groups:delayed cerebral ischemia (DCI) group (n =69) and non DCI group (n =148).A retrospective analysis of 217 cases of patients was performed with inflammation-related factors,and its relationship with clinical prognosis of patients with DCI was also analyzed.Results The inflammation-related factors (WBC count,erythrocyte sedimentation rate,and C-reactive protein) in DCI group were significantly higher than those in non DCI group with a statistically significant difference (P ＜ 0.05).The follow-up results showed that there were 33 patients died,12 cases of plant survival,and 12 patients with severe disability in DCI group,which had a statistically significant difference relative to non DCI group (P ＜ 0.05).Spearman analysis showed that there was a significantly negative relationship between inflammation-related factors (white blood cell count,ESR,C-reactive protein) and glasgow prognostic score (GOS) in DCI group(r =-0.877,-0.683,-0.841,P ＜0.05).Conclusions The inflammation-related factors can be used as one of method to predict delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage.
