Abstract：Objective To investigate the correlation of CT blend signs,swirl signs for hematoma expansion(HE)in early spontaneous intracerebral hemorrhage(SICH).Methods 83 patients with SICH were divided into HE group and non-HE group after CT examination within 6 hours and 24 hours.The clinical data,glasgow coma scale(GCS),imaging data and the re-ceiver operating characteristic curve(ROC)of two groups were compared to evaluate the influence factors of early HE of SICH.Results Univariate between-group analysis showed a significant difference between the two groups in terms of blend sign,swirl sign,combined signs,hypertension,combined ventricular hemorrhage,hematoma volume and GCS score(P<0.05);Logistic regression analysis showed that blend sign,swirl sign,combined signs,hypertension,combined ventricular hemorrhage,hema-toma volume and GCS score were all independent risk factors for predicting HE(P<0.05);and The ROC curve analysis showed that the area under the curve of the blend sign,swirl sign and combined signs in predicting early spontaneous were 0.699,0.720 and 0.825.The sensitivity of blend sign,swirl sign and combined signs in predicting early spontaneous hemorrhage were 70.0%,66.7%and 80.0%.The specificity was 69.8%,77.4%and 84.9%,respectively.Conclusions Both blend sign and swirl sign predict early hematoma expansion and combined signs are more valuable.
