摘要
目的探讨CT血管成像(CTA)对急性脑梗死患者颈动脉狭窄、侧支循环的评估价值。方法回顾性分析101例急性脑梗死(ACI)患者的CTA资料。以数字减影血管造影(DSA)为金标准,分析CTA检查对ACI患者颈动脉狭窄及侧支循环情况的诊断一致性、评估价值,计算诊断效能指标。结果CTA评估颈动脉正常、闭塞的结果与金标准具有高度一致性,评估价值较高[(Kappa>0.8~1.0,曲线下面积(AUC)>0.9,P<0.01)];CTA评估颈动脉轻度狭窄、中度狭窄、重度狭窄的结果与金标准具有中度一致性,评估价值中等(Kappa>0.6~0.8,AUC>0.7~0.9,P<0.01);CTA评估侧支循环的结果与金标准具有高度一致性,评估价值较高(Kappa>0.8~1.0,AUC>0.9,P<0.01)。结论CTA对于ACI患者颈动脉狭窄程度及侧支循环状态具有较高的评估价值。
Objective To analyze the value of computed tomography angiography(CTA)in evaluating carotid artery stenosis and collateral circulation in patients with acute cerebral infarction.Methods A retrospective study was performed to retrospectively analyze the CTA materials of 101 cases with acute cerebral infarction(ACI).Taking Digital Subtraction Angiography(DSA)as gold standard,diagnostic consistency and assessment value of CTA in carotid artery stenosis and collateral circulation in patients with ACI were analyzed,and diagnosis efficiency indexes were calculated.Results The results of CTA in evaluation of carotid artery conditions(normality or occlusion)by CTA were highly consistent with the gold standard,with higher consistency[Kappa>0.8~1.0,area under the curve(AUC)>0.9,P<0.01].The results of CTA in evaluation of mild,moderate and severe carotid artery stenosis were moderately consistent with the gold standard,with medium consistency(Kappa>0.6~0.8,AUC>0.7~0.9,P<0.01).The result of CTA in evaluation of collateral circulation was highly consistent with the gold standard,with higher value(Kappa>0.8~1.0,AUC>0.9,P<0.01).Conclusion CTA has a higher value in evaluating the degree of carotid stenosis and collateral circulation in patients with acute cerebral infarction.
