The Predictive Value of CT Black Hole Sign,Satellite Sign,and Mixed Sign for Spontaneous Intracerebral Hemorrhage Hematoma Enlargement
Objective To analyze the predictive value of CT black hole sign,satellite sign,and mixed sign for spontaneous intracerebral hemorrhage hematoma enlargement.Methods A total of 60 patients with spontaneous cerebral hemorrhage were selected,all admitted to the hospital from July 2021 to November 2023.Within 6 hours of onset,all patients completed baseline CT scans and underwent CT scans within 24 hours of the first scan.According to the increase in hematoma,they were divided into two groups:the group with increased hematoma and the group without increased hematoma,Retrospective analysis of patient general information and imaging data was conducted,and analysis of the influencing factors of early hematoma enlargement in spontaneous cerebral hemorrhage using a multivariate logistic regression model.Select the ROC curve to calculate the area under the curve(AUC),and analyze the value of predicting CT black hole sign,satellite sign,and mixed sign separately,as well as the combination of the three in predicting early hematoma enlargement in spontaneous cerebral hemorrhage.Results Among all 60 patients with spontaneous cerebral hemorrhage,CT scan re examination results showed that 28 patients experienced hematoma enlargement(hematoma enlargement group),the incidence of early hematoma enlargement was 46.67%.The results of univariate analysis showed that the admission NIHSS score of the hematoma enlargement group was significantly higher than that of the non hematoma enlargement group,and the volume of admitted hematoma waslarger than that of the non hematoma enlargement group.The number of black hole sign,satellite sign,and mixed sign cases were higher than those of the non hematoma enlargement group,and the difference was statistically significant(P＜0.05).The results of multivariate analysis showed that independent factors predicting early hematoma enlargement included black hole sign,satellite sign,and mixed sign(P＜0.05).When predicting early hematoma enlargement in patients with spontaneous cerebral hemorrhage,the AUC of black hole sign is 0.659,and the AUC of satellite sign is 0.701;The AUC of the mixed sign is 0.823,and the combined AUC of each sign is 0.899,which is higher than any single sign,and the difference is statistically significant(P＜0.05).Conclusion CT black hole sign,satellite sign,and mixed sign are typical imaging manifestations of early hematoma enlargement in patients with spontaneous cerebral hemorrhage.CT black hole sign,satellite sign,and mixed sign can accurately predict early hematoma enlargement in patients with spontaneous cerebral hemorrhage.The combination of these signs can significantly improve the sensitivity and specificity of prediction.
