【摘要】 目的 通过对颈动脉超声检查,了解颈动脉斑块与相关因素之间的关系。方法 运用多普勒超声对113例颈动脉硬化患者进行超声分型:脂质沉积,粥样斑块,斑块合并狭窄。测量内膜中层厚度(IMT),阻力指数(RI),最大流速(VP)并收集资料,了解与相关因素之间的关系,指出危险因素。结论 IMT随颈动脉硬化增厚,颈动脉硬化随斑块形成而加重,管腔变窄,狭窄处阻力指数增加,流道变细流速加快。提出颈动脉超声检查及危险因素调查可作为老年人筛选预测脑血管疾病的高危人群的无创伤检查方法。

Relationship between carotid artery plaques diagnosed by sonography and related factors
Shen Mei Zheng, Yang Chen
[Abstract] Objective To investigate the relationship between carotid artery plaques and related factors, cerebral infarction with carotid artery sonography. Methods 113 patients with carotid artery sclerosis were divided by doppler sonography : fat sediment, atherosclerotic plaque, plaques with stenosis. IMT, RI, VP were measured and materials were collected to find the relationship between carotid artery sclerosis and related factors point the risk factors. Conclusions IMT became thicker with carotid artery sclerosis, and the latter became more serious when plaques formed, the vessels became narrower , RI and VP became higher ......
