Abstract:
Objective To analyze the relationship of capillary index score(CIS)with postoperative outcome in the patients with middle cerebral artery(MCA)M1 segment stenosis after endovascu-lar stent implantation.Methods A total of 122 eligible patients in our hospital from April 2021 to April 2023 were retrospectively recruited,and according to postoperative status,they were classi-fied into a good prognosis group(89 cases)and a poor prognosis group(33 cases).The clinical data were collected,and the preoperative and postoperative CIS values were evaluated.Spearman correlation analysis was applied to analyze the correlation of CIS with prognosis of the patients.ROC curve was plotted to evaluate the value of CIS in predicting postoperative prognosis,and multivariate logistic regression analysis was utilized to analyze the factors affecting the postopera-tive prognosis.Results The poor prognosis group exhibited significantly lower CIS,and larger proportions of aged ≥75 years,diabetes and history of stroke than the good prognosis group(P＜0.05,P＜0.01).Spearman correlation analysis found that CIS was positively correlated with prog-nosis after endovascular stent implantation in the patients with MCA M1 segment stenosis(r=0.446,P=0.000).ROC curve analysis revealed that the AUC,cut-off value,sensitivity and speci-ficity of CIS in predicting the postoperative outcomes in these patients was 0.790(95％CI:0.706-0.858),2.17,84.85％and 66.29％,respectively(P＜0.05).Multivariate logistic analysis suggested that age ≥75 years,history of stroke,and concurrent diabetes were high risk factors for poor prognosis in the patients after endovascular stent implantation(P＜0.05,P＜0.01),and CIS was a protective factor(OR=0.439,95％CI:0.294-0.655,P=0.000).Conclusion CIS is closely correlated with the prognosis of patients with MCA M1 segment stenosis after endovascular stent implantation.Early evaluation of CIS can provide certain predictive value for postoperative out-comes of these patients.
