摘　　要：【目的】评价彩色多普勒血流显像(CDFI)检测颈动脉粥样硬化的超声改变与临床价值。【方法】观察颈总动脉及其分叉处、颈内动脉、颈外动脉内中膜厚度、斑块回声及血流动力学改变。【结果】本组3670例就诊患者中,颈动脉无病变者1874例(51.1%),有粥样硬化者1796例(48.9%)。在有颈动脉粥样硬化患者中,仅表现内中膜增厚或同时伴有斑块者692例(38.5%),形成颈动脉轻度狭窄者381例(21.2%),中度狭窄者423例(23.6%),重度狭窄者266例(14.8%),闭塞者34例(1.9%)。本组经CT、MRI确诊的脑梗塞患者612例,其中有456例CDFI检测出颈动脉粥样硬化斑块,占74.51%。糖尿病合并高血压者685例,CDFI检测有577例有颈动脉粥样硬化,占84%。【结论】CDFI可作为检测颈动脉粥样硬化的首选方法,能提供颈动脉内中膜增厚和斑块等医学信息,提示脑血管病的高危状态,对高血压、糖尿病及脑梗塞患者的检出率高于正常人,有很高的临床价值。[Objective] To evaluate the color doppler flow imaging （CDFI） in detection of carotid atherosclerosis and clinical value. [Methods] To observe the common carotid artery and its bifurcation, the internal carotid artery, external carotid artery intima-media thickness, plaque echo and hemodynamic changes. [Results] 3670 cases of this group, 1874 cases without carotid artery disease （51.1%）, and atherosclerosis were 1796 cases （48.9%） . In suffering from arteriosclerosis, only in the performance of membrane thickening or plaques are accompanied by 692 eases （38.5 % ）, the mild carotid artery stenosis in 381 cases （21.2%）, moderate stenosis in 423 cases （23.6%）, severe stenosis in 266 cases （14.8 % ）, carotid artery occlusion were 34 cases （1.9 % ） . In this group, by C T, M RI diagnosed 612 cases of cerebral infarction patients, including 456 cases of carotid artery ultrasound to detect atherosclerosis, accounting for 74.51%. In 685 eases with diabetes and hypertension, CDFI detected 577 eases of carotid atheroselerosis, accounting for 84%. [ Con- clusions] CDFI, which provides carotid intima-media thickening and plaque and other medical information, has a higher atheroselerosis detection rate in patients with hypertension and diabetes than normal. CDFI can he preferred used in detection of carotid atheroselerosis which has important clinical value.
