Objective The combined detection of serum angiopoietin-like protein 8(ANGPTL8)and Vascular cell adhesion molecule-1(VCAM-1)levels was analyzed for the predictive value of cerebral vasospasm(CVS)after intracranial aneurysm embolization.Methods A total of 196 patients who underwent intracranial aneurysm embolization in our hospital from March 2019-March 2022 were selected as the study subjects,99 patients with CVS were in the CVS group,and 97 patients without CVS were in the non CVS group.Serum ANGPTL8 and VCAM-1 levels were detected by ELISA;the correlation between serum ANGPTL8 and VCAM-1 levels was analyzed by Pearson method,Logistic regression was used to analyze the influencing factors of CVS in patients undergoing intracranial aneurysm embolization;ROC curve was used to analyze the serum levels of ANGPTL8 and VCAM-1 to predict the cutoff value of CVS in patients undergoing intracranial aneurysm embolization;four grid table method was used to analyze the predictive value of ANGPTL8,VCAM-1 and their combination on the occurrence of CVS in patients undergoing intracranial aneurysm embolization.Results The differences between CVS and non-CVS groups were statistically significant in hypertension,Hunt-Hess grade,and Glasgow coma(GCS)scores(P＜0.05).The serum ANGPTL8 and VCAM-1 levels in the CVS group were significantly higher than those in the non-CVS group(P＜0.05).There was a positive correlation between serum ANGPTL8 and VCAM-1(r=0.468,P＜0.05).Multivariate analysis showed that high level of ANGPTL8(OR=3.652,95％CI:1.434-9.302),high level of VCAM-1(OR=2.619,95％CI:1.212-5.658),Hunt Hess grade Ⅲ-Ⅳ(OR=1.927,95％CI:1.104-3.362),GCS score of 3-8(OR=2.813,95％CI:1.257-6.295)were independent risk factors for CVS in patients undergoing intracranial aneurysm embolization.The AUC of serum ANGPTL8 level in predicting CVS in patients undergoing intracranial aneurysm embolization was 0.844,and the cut-off value was 189.233 U/L;the AUC of serum VCAM-1 level in predicting CVS in patients undergoing intracranial aneurysm embolization was 0.795,and the cutoff value was 17.984 mg/L.The accuracy,sensitivity and specificity of the combined prediction for CVS were 89.81％,93.94％and 85.57％,respectively,which were obviously higher than those of the single prediction.Conclusion The serum levels of ANGPTL8 and VCAM-1 in CVS group are obviously higher than those in non CVS group.The combination of the two has a high predictive value for CVS after intracranial aneurysm embolization.
