1、彩色多普勒超声诊断下肢静脉血栓中的临床意义李晓桐(四川省资阳市第一人民医院超声科四川资阳641300)【摘要】目的：分析彩色多普勒超声在下肢静脉血栓诊断中的应用价值。方法：回顾性分析我院120例下肢静脉血栓患者的临床资料，将其分为观察组，并以同期健康体检者120例为对照组，两组研宄对象均进行彩色多普勒超声检查，分析两组的超声特点、下肢静脉血栓患者血栓分布情况及急性血栓、亚急性血栓、慢性血栓的相关情况。结果：观察组120例患者中单侧血栓形成106例，双侧14例，其中左侧85条，右侧49条。120例患者血栓分布部位分析：胴静脉比例最高，为23.94%,其次为
2、腓静脉22.54%及股静脉18.31%;120例患者中，65例为急性血栓，29例为亚急性血栓，余者26例为慢性血栓患者。急性血栓发病急，超声检查可见血栓部位管径加粗，血栓内部表现较弱实性回声，周围模糊，远端血流速度放慢；而慢性血栓患者血栓部位管径加粗不明显，内部表现较强的实性回声，梗阻程度会对远端血流变化产生直接影响。结论：彩色多普勒超声可直接观察下肢静脉血管腔内的血栓回声，对下肢静脉血栓特异性较高，为临床诊断提供准确依据。【关键词】彩色多普勒超声：下肢静脉血栓；应用价值【中图分类号1R543.6【文献标识码】A【文章编号】1004-6194(2015)
