摘要
目的本研究目的分析颈动脉夹层的超声表现,总结颈动脉夹层超声特征。方法选择2007年1月~2014年12月北京天坛医院经MRA（n=10）和/或DSA（n=10）证实的颈动脉夹层患者共计20例,男17例,女3例,年龄25~68岁（中位年龄46岁）,结合MRA或DSA分析颈动脉夹层在超声影像中的图像特征。结果 20例颈动脉夹层患者其中颈总动脉夹层5例,颈内动脉夹层15例。超声能够明确诊断颈动脉夹层患者12例,表现为典型＂双腔管＂征（真腔和假腔）,检出率60%;超声诊断颈动脉夹层总符合率75%,漏诊率25%。Youden指数为75%。结论超声诊断颈动脉夹层与DSA/MRA相比具有较高符合率,可以作为评价颈动脉夹层的首选无创性筛查手段,最终诊断依赖于DSA/MRA。
Objective To summarize the ultrasound（US）characteristics of carotid artery dissection.Methods US characteristics of 20 patients（3 women and 17men;mean age;46 years;range;25-68 years）with extracranial internal（15）or common（5）carotid artery dissection proved by angiography and/or MRA were analyzed.Results Dissection could be definitely diagnosed on US in 12/20 patients with pathognomonic signs of double lumen or an intimal flap on axial imaging.The correlation rate of US diagnosis was 75%with Youden index of 75%.Conclusion US is a reliable noninvasive tool in early diagnosis of carotid artery dissection.
