彩色多普勒超声在下肢深静脉血栓诊断中的应用

目的 探讨彩色多普勒超声对下肢深静脉血栓（DVT）的诊断价值.方法 将2009年1月-2009年12月间在我院诊疗的下肢DVT患者36例进行彩色多普勒超声诊断,并了解其诊断价值.结果 彩色多普勒超声诊断准确率为100.00%.急性下肢DVT 25例,二维超声显示：栓塞静脉增宽,呈中低回声,管壁无增厚,管腔加压不能被压闭;CDFI可探及条状血流信号或无血流信号.亚急性和慢性下肢DVT 11例,二维超声显示：管壁与血栓界线欠清,管壁增厚,呈高回声;CDFI可探及条带状血流,可见丰富的侧支血流.结论 彩色多普勒超声对下肢DVT的诊断准确性高,操作方便,值得应用.

Color doppler ultrasound in the diagnosis of lower extremity deep vein thrombosis

Objective To explore the value of color doppler ultrasound in the diagnosis of lower extremity deep vein thrombosis (DVT). Methods 36 patients with lower extremity DVT treated from January 2009 to December 2009 in our hospital were detected by color doppler ultrasound. Results The accurate rate of deep vein thrombosis in the lower extremity was 100.00%. 25 patients developed acute DVT.Two-dimension ultrasound showed the veins with embolism were widen, with low to moderate level of echo,without thickening dissepiments, and the lumens could not be press to closing. CDFI revealed signs of strip blood stream sign or without the signs. 11 patients had subacute or chronic DVT. Two-dimension ultrasound showed no obvious limit between dissepiments and thrombus, with thickening disaepiments and high level of echo. CDFI revealed signs of strip blood stream and affluent collateral branch blood stream. Conclusions Color doppler ultrasound is accurate and easy to run in the diagnosis of lower extremity deep vein thrombosis.It is worth popularizing.
