摘要
目的 探讨颈动脉粥样硬化双功能高频超声表现与病理及相关疾病的关系。方法 用高频超声对 93例受检者颈部动脉血管作横向及纵向扫查 ,观察和测量血管内径、内壁回声、狭窄程度、血流速度、阻力指数。结果 颈动脉粥样硬化有 61例( 61 93) ,占 65 .6% ,轻度狭窄 39例 ,中度和重度狭窄各 1例 ,动脉壁有广泛的粥样硬化时血流速度增快 ,阻力指数 >0 .8。结论 各种相关疾病的动脉粥样硬化声像图表现相同。不同回声的斑块 ,反映病变的不同时期、轻重程度 ,对病因分析 。
Objective To investigate the correlation of high-frequency ultrasonography sign and pathology and the relative disease about carotid atherosclerosis.Methods 93 patients's carotid artery were transverse scanned and longitudinal scanned with high-frequency probe.We observed and measured the internal diameter of the bloodvessel,echo sign of the internal wall,stenosis extent,the nature of blood flow,the velocity of blod flow and resistant index (RI).Results 61 patients have carotid atherosclerosis (65.5%),39 patients have minimum stenosis,1 patient has medium stenosis and 1 patient has serious stenosis.The velocity of blood flow will change higher and RI>0.8 when the wall of artery have atherosclerotic plaque widely.Conclusions The ultrasono graphy signs of all kinds of relative diseaes about atherosclerosis are same. Different echo of the atherosclerotic plaque could reflect the different thim and different degree of carotid atherosclerosis.It is of great value in analyzing reansons, preventing and treating early.
