多普勒彩色超声诊断颈动脉窦处动脉粥样硬化斑块形成致进食晕厥的应用价值

Application of Color Doppler Ultrasound in the Diagnosis of Atherosclerotic Plaques Formation in Carotid Sinus Syncope Induced by Eating Triggers

目的探讨多普勒彩色超声诊断颈动脉窦处动脉粥样硬化斑块形成致进食晕厥的应用价值。方法选取我院于2011年1月—2014年7月收治的9例颈动脉窦处动脉粥样硬化斑块形成致进食晕厥病人为研究对象,均进行多普勒彩色超声检查,观察其颈动脉各处内中膜厚度变化及粥样硬化斑块形成特点。结果 9例病人手术时发现21个斑块,而进行多普勒彩色超声检测时检出17个,检出率为81.0%,其中软斑块5个(23.8%),硬斑块4个(19.1%),混合斑块12个(57.1%);血管轻度狭窄者5例(55.6%),中度狭窄者3例(33.3%),重度狭窄者1例(11.1%)。所有病人均存在颈动脉内中膜增厚及动脉粥样硬化斑块形成。结论颈动脉粥样硬化斑块形成是一种临床常见疾病,但其致进食昏厥于临床诊断及治疗中较为少见,病人多出现双侧颈动脉内中膜增厚、颈动脉粥样硬化斑块形成、局部血流速度明显增快等情况,临床诊断时应利用多普勒彩色超声诊断仪增强准确性,避免误诊及漏诊情况发生。

Objective To evaluate the value of color Doppler ultrasound in the diagnosis of atherosclerosis plaques formation in carotid sinus syncope induced by eating triggers.Methods Nine patients with syncope induced by eating triggers in2007 January to 2013 July were enrolled.The carotid artery intima-media thickness in everywhere and the characteristics of atherosclerotic plaque formation were observed.Results Twthty-one hard plaques were found in 9 patients in surgery,and among them,17 hard ptuques were found by the Doppler ultrasonic detection,the detection rate was 81%.The soft plaque accounted for 5（23.8%）,hard plaque accounted for 4（19.1%）,mixed plaque account for the largest proportion,12（57.1%）.Nine patients were the existence of carotid artery intimamedia thickness and atherosclerotic formation,including 5 cases of vascular mild stenosis（55.6%）,3 patients with moderate stenosis（33.3%）,1 cases of severe stenosis（11.1%）.Conclusion The carotid atherosclerotic plaque formation is a common clinical disease induced by eating triggers,but the clinical diagnosis and treatment of patients are rare,thickening and bilateral carotid artery intimamedia of carotid atherosclerotic plaque formation,local blood flow velocity are papnlar conditions.The color Doppler ultrasound can enhance the accuracy in the clinical diagnosis.
