摘要
目的 探讨头颈部CT血管造影(CTA)诊断急性缺血性脑卒中(AIS)动脉狭窄程度的价值.方法 选取收治的AIS患者 97 例,均行头颈部CTA和数字减影血管造影(DSA)检查,以DSA结果为金标准.评估患者颈动脉狭窄程度.记录头颈部CTA对颈动脉狭窄程度评估准确率,灵敏性和特异性.采用Pearson分析头颈部CTA与DSA诊断颈动脉狭窄程度相关性.结果 97 例脑梗死患者中,DSA金标准检查正常～轻度狭窄患者 41 例,中度～重度狭窄患者 56 例.经头颈部CTA检查中度～重度狭窄准确率为 96.43%.头颈部CTA诊断颈动脉中度～重度狭窄诊断灵敏性为 92.86%,特异性为 95.12%.经Pearson分析显示,头颈部CTA与DSA诊断颈动脉狭窄程度呈正相关(P<0.05).中度～重度狭窄组斑块数量多于正常～轻度狭窄组,斑块长度高于正常～轻度狭窄组,斑块厚度小于正常～轻度狭窄组,差异有统计学意义(P<0.05).结论 头颈部CTA对AIS患者颈动脉狭窄程度评估价值良好.
Abstract
Objective To explore the value of head and neck CT angiography(CTA)in diagnosing the degree of arterial ste-nosis in acute ischemic stroke(AIS).Methods 97 AIS patients all underwent head and neck CTA and digital subtraction angi-ography(DSA)examinations,with DSA results as the gold standard.We assessed the degree of carotid artery stenosis in the pa-tient and recorded the accuracy,sensitivity,and specificity of head and neck CTA in assessing the degree of carotid artery steno-sis.Pearson analysis was used to examine the correlation between head and neck CTA and DSA in diagnosing the degree of ca-rotid artery stenosis.Results Among 97 patients with cerebral infarction,41 patients with normal to mild stenosis and 56 pa-tients with moderate to severe stenosis were detected by DSA gold standard examination.The accuracy of CTA examination for moderate to severe stenosis in the head and neck was 96.43%.The sensitivity and specificity of head and neck CTA in diagnosing moderate to severe carotid artery stenosis were 92.86%and 95.12%,respectively.According to Pearson analysis,there was a positive correlation between head and neck CTA and DSA diagnosis of carotid artery stenosis(P<0.05).The number of plaques in the moderate to severe stenosis group were higher in normal to mild stenosis group,and the plaque length was higher in normal to mild stenosis group.The plaque thickness was smaller in normal to mild stenosis group(P<0.05).Conclusion Head and neck CTA has good value in evaluating the degree of carotid artery stenosis in AIS patients,with high diagnostic accuracy,sensi-tivity,and specificity,which is worth of clinical reference.
