超声对颈动脉蹼的诊断价值及漏诊误诊分析

The diagnostic value of ultrasound in carotid web and the characteristics of misdiagnosed cases

回顾性收集2018年1月1日至2021年12月31日于郑州大学第一附属医院超声诊断为颈动脉蹼或经计算机断层血管成像(CTA)或手术病理证实的颈动脉蹼患者资料,共42例,其中男20例、女22例,年龄35~77(55±11)岁。按超声诊断颈动脉蹼的正确与否分为超声漏诊误诊组(MD组,10例)和超声正确诊断组(CD组,32例)。MD组较CD组的颈动脉蹼易合并斑块(100.00%比12.50%)、局部血管重度狭窄(70.00%比0)或闭塞(30.00%比0)(均P<0.05),也更常见颈动脉内中膜增厚(80.00%比28.13%)和颈动脉其他部位斑块(100.00%比37.50%)(均P<0.05)。此外,超声诊断颈动脉蹼的准确率高于CTA(76.19%比59.52%,P=0.039)。

Data of 42 patients with carotid web diagnosed by ultrasound or confirmed by computed tomography angiography(CTA)or surgical pathology in the First Affiliated Hospital of Zhengzhou University were retrospectively collected,including 20 males and 22 females,aged 35-77(55±11)years.According to the accuracy of ultrasound diagnosis of carotid web,the patients were divided into Group of misdiagnoses by ultrasonoscopy(MD group,10 cases)and Group of correct diagnosis by ultrasonoscopy(CD group,32 cases).Compared with CD group,carotid webs in MD group were more likely to be associated with plaque(100.00%vs 12.50%),severe local vascular stenosis(70.00%vs 0)or occlusion(30.00%vs 0)(all P<0.05),carotid intima-media thickening(80.00%vs 28.13%)and plaque formation in other parts of carotid artery(100.00%vs 37.50%)(both P<0.05).Moreover,the correct diagnosis rate of ultrasound was higher than that of CTA(76.19%vs 59.52%,P=0.039).
