颈内动脉粥样硬化斑块的超声诊断价值

Diagnostic Value of Ultrasound on Atherosclerotic Plaque of Internal Carotid Artery

目的探讨颈内动脉粥样硬化斑块的超声诊断价值。方法回顾性分析2014-2016年在辽宁省北票市中心医院接受颈部血管超声检查的患者198例，对其血管及粥样斑块的超声声像特征进行分析。结果颈内动脉狭窄263个，其中轻度狭窄65个（24．7％）、中度狭窄131个（49．8％）、重度狭窄52个（19．8％）、闭塞15个（5．7％）。粥样硬化斑块377个，其中Ⅰ型斑块1154-（30．5％）、Ⅱ型斑块194个（51．5％）、Ⅲ型斑块68个（18．0％）；硬斑块165个（43．8％）、软斑块129个（34．2％）、混合型斑块83个（22．0％）。结论超声诊断颈内动脉粥样硬化斑块具有较好的应用价值，可作为常规筛查手段推广应用。

Objective To discuss the diagnostic value of ultrasound on atherosclerotic plaque of internal carotid artery. Methods One hundred and ninety-eight cases of patients who accepted ultrasonic examination on internal carotid artery in Beipiao Central Hospital from 2014 to 2016 were analyzed retrospectively. Ultrasonic imaging characteristics of blood vessel and atherosclerotic plaque of the patients were analyzed. Results There were 263 cases of internal carotid arteries with stenosis including 65 cases with mild stenosis （24.7%）, 131 cases with moderate stenosis （49.8%）, 52 cases with severe stenosis （19.8%） and 15 cases with occlusion （5.7%）. There were 377 atherosclerotic plaques including 115 plaques of Type Ⅰ （30.5%）, 194 plaques of Type Ⅱ （51.5%） and 68 plaques of Type Ⅲ （18.0%）. There were 165 hard plaques （43.8%）, 129 soft plaques （34.2%） and 83 mixed plaques （22.0%）. Conclusion The ultrasound has good diagnostic value on atherosclerotic plaque of internal carotid artery, which can be regarded as routine screening to be promoted.
