摘　　要：目的探讨CT血管造影(CTA)在判断大脑中动脉区脑梗死患者血管狭窄程度及其与脑梗死程度的相关性中的应用价值。方法选取2017年1月1日～12月31日我院收治的100例疑似大脑中动脉区脑梗死患者作为研究对象,对其实施CTA检查,分析其检查结果,以数字减影血管造影(DSA)诊断结果为参照,计算CTA对大脑中动脉区脑梗死的诊断灵敏度、特异度、准确率及对血管狭窄程度的诊断符合率,并分析CTA与DSA诊断结果之间的一致性,分析大脑中动脉区脑梗死患者血管狭窄程度与脑梗死程度的相关性。结果 CTA对大脑中动脉区脑梗死的诊断灵敏度、特异度、准确率分别为94.94%、90.48%、94.00%,对轻度狭窄、中度狭窄、重度狭窄、血管闭塞的诊断符合率分别为90.91%、92.31%、94.12%、85.71%,其诊断结果与DSA诊断结果之间的一致性良好(Kappa=0.759)。经相关性分析,大脑中动脉区脑梗死患者的血管狭窄程度与其脑梗死程度密切相关,两者成正相关(P<0.05)。结论 CTA可对大脑中动脉区脑梗死予以灵敏、准确诊断,可用于大脑中动脉区脑梗死诊断及血管狭窄程度判断中,有利于为大脑中动脉区脑梗死患者脑梗死程度预测提供可靠依据。Objective To investigate the application value of computed tomography angiography(CTA)in judging the degree of vascular stenosis and its correlation with cerebral infarction in patients with middle cerebral artery infarction.Methods A total of 100 patients suspected with middle cerebral artery cerebral infarction admitted to our hospital from January 1 to December 31,2017 were selected as the subjects.All participants were performed with CTA in order to analyze the inspection results.The diagnostic results of digital subtraction angiography(DSA)were used as a reference,the diagnostic sensitivity,specificity,accuracy and diagnostic compliance rate of vascular stenosis by CTA in the middle cerebral artery infarction region were calculated,and the consistency of diagnostic results between CTA and DSA was analyzed in order to explore the correlation between the degree of vascular stenosis and the degree of cerebral infarction in patients with middle cerebral artery infarction region.Results The diagnostic sensitivity,specificity and accuracy of CTA in the middle cerebral artery infarction region were 94.94%,90.48% and 94.00% respectively.The diagnostic consistency for mild,moderate,severe stenosis,and vascular occlusion were 90.91%,92.31%,94.12%,and 85.71%.The consistency of diagnostic results between CTA and DSA was good(Kappa=0.759).Correlation analysis showed that the degree of vascular stenosis in patients with middle cerebral artery infarction region was closely related to the degree of cerebral infarction in a positive manner(P<0.05).Conclusion CTA can be sensitive and accurate for the diagnosis of middle cerebral artery infarction region.It can be used for the diagnosis of cerebral infarction in the middle cerebral artery region and the judgment of vascular stenosis,which is beneficial to provide a reliable basis for predicting the degree of cerebral infarction in patients with middle cerebral artery region.
