彩色多普勒超声检测颈动脉粥样硬化的临床应用价值

【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又处、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。

Clinical value of color dopper ultrasound in detection of carotid atherosclerosis

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 arte-riosclerosis, only in the performance of membrane thickening or plaques are accompanied by 692 cases (38.5%), the mild carotid artery stenusis 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 CT, MRI diagnosed 612 cases of cerebral infarction patients, including 456 cases of carotid artery ultrasound to detect atherosclerosis, accounting for 74.51%. In 685 cases with diabetes and hypertension, CDFI detected 577 cases of carotid atherosclerosis, accounting for 84%. Con-clusions] CDFI, which provides carotid intima-media thickening and plaque and other medical information, has a higher atherosclerosis detection rate in patients with hypertension and diabetes than normal. CDFI can be preferred used in detec-tion of carotid atherosclerosis which has important clinical value.
