目的：探讨彩色多普勒超声(CDFI)在儿童过敏性紫癜致下肢静脉瓣膜功能不全中诊断价值。方法：对2006年至2014年经临床诊断过敏性紫癜引发下肢静脉瓣膜功能不全8例患儿的超声图像资料进行回顾、归纳总结。结果：8例患儿下肢深静脉表现血液流速稍减慢，CDFI呈节阶段性红蓝相间血流，频谱多普勒呈节段性基线上下血流频谱。结论：CDFI为儿童急性过敏性紫癜致急性双下肢静脉瓣膜功能不全提供了早期、无创和具有高敏感性、特异性的检查方法。

Objective:To discuss value of CDFI in diagnosis of pediatric allergic purpura caused acute deep venous valvular insufifciency of lower extremities. Methods:8 children with allergic purpura caused acute deep venous valvular insufifciency of lower extremities were studied retrospective1y. Results: Blood lfow velocity showed slower in lower limb deep vein,CDFI showed segmental red and blue, spectral doppler showed segmental up and down of baseline blood lfow spectrum. Conclusion: CDFI as a highly sensitive, speciifc and non-invasive procedure used at pediatric allergic purpura caused acute deep venous valvular insufifciency of lower extremities.
