彩色多普勒超声诊断脑血管病颈动脉粥样硬化的临床意义

目的:探讨彩色多普勒超声检测脑血管病患者颈动脉硬化的特点及应用价值。方法:对130例脑血管病例和非脑血管病患者73例为对照组进行超声检测,检测内容包括颈动脉内-中膜厚度(IMT),颈动脉斑块及血流动力学等,并对结果进行分析。结果:脑梗死组和TIA组IMT与对照组比较,差异有统计学意义(P<0.01)。130例脑血管病患者中颈动脉有粥样硬化、斑块形成等血管异常112例,异常检测率86.15%;对照组中有斑块形成19例,异常检测率26%。两者比较有显著性差异(P<0.01)。颈动脉粥样硬化斑块最常见于颈动脉分叉处,其次为颈内动脉起始处。而左右侧间差异无显著性(P>0.05)。结论:脑血管病患者多继发颈动脉粥样硬化斑块,使用彩色多普勒超声能准确有效的评价颈动脉病变的程度,为有效的预防和治疗老年血管性病变提供依据具有十分重要的意义。

Objective：To investigate the use of Color Doppler ultrasound in the diagnosis of carotid artery scleratheroma among the patients with cerebral vessels diseases. Methods ：203 cases data diagnosised by Color Doppler Ultrasound were collected, 130 cases in which suffered cerebral vessels diseases, while the remains 73 cases were free from cerebral vessels diseases as control, retrospective analysis was performed for all data. Results： 112 cases were diagnosised with plaque formation from 130 cases suffered cerebral vessels diseases （86.15%） ; in the control group, 19 cases were diagnosised with plaque formation （ 26% ） （ P 〈 0.01 ）. the rate of plaque formation happened on carotid artery bifurcate was higher than that of the initial site of cervical internal carotid artery, between the right and left carotid artery, there was no significance in statistics （ P 〉0. 05 ）. Conclusions ： Carotid artery scleratheroma generally result from cerebral vessels diseases, Color Doppler Ultrasound can evaluate the degree of carotid artery pathological change precisely, which can provide diagnosis evidence for prevention and therapy vessels diseases among elders effectively.
