CT“李琦岛征”和“黑洞征”对脑挫裂伤血肿扩大的预测价值

The Predictive Value of CT "Li Qi Island Sign" and "Black Hole Sign" on the Enlargement of of Hematoma in Cerebral Contusion and Laceration

目的探讨"李琦岛征"和"黑洞征"对脑挫裂伤血肿扩大的预测价值。方法回顾性分析我院2016年1月至2017年12月期间96例脑挫裂伤血肿扩大患者的早期CT表现及临床资料,并评价"李琦岛征"和"黑洞征"预测脑挫裂伤血肿扩大的敏感性、特异性、阳性预测值和阴性预测值。结果412例脑挫裂伤血肿患者中经CT随访复查确诊血肿扩大96例,其中扩大的血肿早期CT表现为"李琦岛征"44例,"黑洞征"38例,其它14例;在脑挫裂伤血肿扩大预测方面,"李琦岛征"和"黑洞征"的敏感性分别为45.83%、39.58%;特异性分别为96.52%、94.94%;阳性预测值分别为80.00%、70.37%;阴性预测值分别为85.43%、84.03%。结论CT"李琦岛征"和"黑洞征"是脑挫裂伤血肿可靠CT征象,可有效预测脑挫裂伤血肿扩大的风险,"李琦岛征"和"黑洞征"在脑挫裂伤患者血肿扩大的预测中有重要价值。

Objective To explore the predictive value of "Li qi island sign" and "black hole sign" on the enlargement of hematoma in cerebral contusion and laceration.Methods a retrospective analysis in 96 cases of contusion and laceration of brain hematoma enlargement in patients our hospital from January 2016 to December 2017 with early CT findings and clinical data,and evaluate the "Li qi island sign " and "black holesign" the predictive value of sensitivity and specificity,positive predictive value and negative laceration hematoma enlargement in predicting cerebral contusion.Results 412 cases of cerebral contusion patients were followed by CT diagnosed hematoma enlargement in 96 cases,hematoma early manifestations of CT for expanding "Li qi island sign " in 44 cases,the "black hole" sign in 38 cases,the other 14 cases;in the prediction of cerebral contusion and laceration of hematoma expansion,"Li qi island sign" and "black hole.sign" the sensitivity was 45.83%,specificity was 39.58%;96.52%,94.94%;the positive predictive value were 80%,70.37%;negative predictive value were 85.43%,84.03%.Conclusion CT "Li qi island sign" and "black hole sign" are reliable CT signs of cerebral contusion and hematoma,which can effectively predict the risk of enlargement of hematoma in cerebral contusion and laceration."Li qi island sign" and "black hole sign" are of great value in the prediction of hematoma enlargement in patients with cerebral contusion and laceration.
