双功能彩色多普勒超声评价高粘滞血症与颈动脉硬化闭塞症的关系

Evaluation of the relationship between hyperviscosity syndrome and ASO by color duplex sonography

目的:通过对高粘滞血症78例及对照组20例颈动脉的超声观察,探讨其与颈动脉硬化闭塞症(arteriosclerosisobliterans,ASO)的关系。方法:收集经血液流变学检测出的高粘滞血症78例及对照组20例,用双功能彩色多普勒超声仪观察颈动脉内径,IMT(血管内膜—中膜的厚度)斑块形成情况,管腔是否狭窄及其程度,并参考高粘滞血症分型标准分为4个亚型,结合B超结果进行分析。结果:高粘滞血症组中,IMT≥1.0mm,各种类型粥样硬化斑块的形成及二者所致的颈动脉狭窄的发病率均高于对照组,且Ⅳ型的腔梗发病率明显高于其它亚型。结论:对高粘滞血症患者行颈动脉双功能彩色多普勒超声检查,可以尽早发现ASO。

Objective:To observe the ultrasonography of carotid artery in78patients with hyperviscosity syndrome and20control cases.To investigate the relationship between hyperviscosity syndrome and arteriosclerosis obliterans(ASO).Methods:The diameter of carotid lumen,intimal thickness,plaque condition,degree of arterial stenosis were observed in78patients with hyperviscosity syndrome and20controls by color duplex sonography,It was divided into four subtypes relavent with hypervis-cosity syndrome classification standard and were analyzed with the result of ultrasonography.Results:In the patients with hy-perviscosity syndrome,IMT ≥1.0mm,with various kinds of atherosclerotic plaque and different degree of arterial stenosis caused by IMT thicken ed and plaque.The incidence of cerebral infarction of type IV hyperviscosity syndrome is much higher than that of the other types.Con clusions:ASO in patients with hyperviscosity syndrome can be discovered early by color duplex sonography.
