摘要
目的探讨16层螺旋CT血管造影(16-MSCTA)在颅外段颈内动脉狭窄病变诊断中的应用价值。方法回顾性分析行颅颈部16-MSCTA检查的拟诊为前循环缺血卒中的23例患者的临床资料,23例患者1周内先后行16-MSCTA与DSA检查,评价16-MSCTA对颅外段颈内动脉狭窄诊断的敏感性、特异性、准确性。结果 23例患者行16-MSCTA和DSA检查共得到46支颅外段颈内动脉图像。16-MSCTA共诊断正常18支,狭窄28支,中度及以上狭窄共20支,占43.48%。DSA共诊断正常19支,狭窄27支,中度及以上狭窄共18支,占39.13%。16-MSCTA对中度及以上狭窄程度诊断评价的敏感性、特异性、准确性分别为90.0%、100.0%、94.7%。结论 16-MSCTA在颅外段颈内动脉狭窄程度分级的判定中与DSA有较高的一致性,16-MSCTA可以作为颅外段颈内动脉狭窄的筛查手段之一。
Objective To explore the applied value of 16-MSCTA in herosclerotic sclerosis lesion of internal carotid artery. Meth- ods The clinical data of 23 cases of patients with isehemic cerebrovascular disease were retrospectively studied. All the 23 cases of patients were checked by 16-MSCTA and DSA in a week and 16-MSCTA diagnostic accuracy,sensitivity and specificity of extra-cra- nial internal carotid artery stenosis were assessed. Results After being checked by 16-MSCTA and DSA,46 branches of carotid artery images were formed. Of all the images checked by 16-MSCTA,normal ones account for 18,stenosis 28,with moderate and severe stenosis 20（43.48%）. Of all the images checked by DSA,normal ones account for 19,stenosis 27,with moderate and severe stenosis 18 （39.13%）. The findings showed that 16-MSCTA diagnostic accuracy was 94.7%, sensitivity 90.0% and specificity 100.0%. Conclusion Assessment of different levels of herosclerotic sclerosis lesion of internal carotid artery by 16-MSCTA was consistent with that by DSA. 16-MSCTA can be used as one of the methods to diagnose the atherosclerotic sclerosis lesion of internal carotid artery.
