颅CT平扫联合CTA征象对自发性脑出血血肿扩大的预测价值

Predictive Value of Cranial CT Scan Combined with CTA Signs for Hematoma Enlargement in Spontaneous Intracerebral Haemorrhage

目的探究颅CT平扫联合CT血管造影(CTA)征象对自发性脑出血血肿扩大的预测价值。方法选取我院收治的86例自发性脑出血患者,均行颅CT平扫及增强扫描。根据入院24h内颅CT复查分为扩大组(31例)和非扩大组(55例)。比较两组临床资料及影像特征,影响因素分析用多因素logistic回归分析,预测价值通过绘制受试者工作特征曲线(ROC曲线)分析。结果经logistic回归分析,CT平扫混合征比例、CTA斑点征比例、总碘浓度及最大碘浓度是影响患者血肿扩大的重要影响因素(P<0.05)。经ROC曲线分析,CT平扫混合征、CTA斑点征、总碘浓度、最大碘浓度联合预测血肿扩大的AUC(0.922)最大。结论颅CT平扫联合CTA征象可提高自发性脑出血血肿扩大的预测价值。

Objective To evaluate predictive value of cranial CT combined with CTA signs for hematoma enlargement in spontaneous intracerebral hemorrhage(sICH).Methods SICH patients(n=86)with plain CT scans and CTA were enrolled and assigned into enlargement group(n=31)and non-enlargement group(n=55)based on image findings.Clinical and imaging features were compared.Logistic regression model and ROC curve were utilized for analysis of influencing factors and predictive value.Results Logistic regression analysis revealed that CT blend sign,CTA spot signs,total and maximum iodine concentration were influencing factors.ROC curve indicated that AUC of combined test of CT blend sign,CTA spot sign,total and maximum iodine concentration for prediction was the largest,reaching 0.922.Conclusions The cranial CT scan combined with CTA signs are of great clinical value for hematoma enlargement prediction in sICH.
