超声弹性成像技术在不同时期下肢深静脉血栓中的应用

Application of Ultrasound Elasticity Imaging Technology in Deep Venous Thrombosis of Lower Limb in Different Periods

目的：研究超声弹性成像技术在不同时期下肢深静脉血栓中的应用。方法：回顾性分析2013年1月～2015年10月71例下肢深静脉血栓患者采取超声弹性成像的资料，比较急性组，亚急性组，慢性组的DVT的超声弹性图特征及评分，比较分析三组DVT弹性应变比值。结果：急性组多显示红色，亚急性组多显示绿色，慢性组多显示蓝色。图像评分各组间比较均具有统计学意义（P＜0.05），慢性组应变比值高于亚急性组和急性组（P＜0.05），亚急性组应变比值高于急性组（P＜0.05）。结论：超声弹性成像技术对下肢深静脉血栓分期具有积极应用价值，能够评价不同时期静脉血栓的硬度变化情况。

Objective: To study the application of ultrasound elasticity imaging technology in the deep venous thrombosis of lower limb in different periods.Methods:A retrospective analysis was taken with the data of J 71 cases of deep vein thrombosis of lower extremity from January 2013 to October 2015.The ultrasound and the score of the DVT in the acute group,subacute group,and the chronic group were compared.Results:The acute group showed more red,the sub acute group showed more green,and the chronic group showed more blue..Image scores were statistically significant among the groups(P<0.05).The ratio of strain in chronic group was higher than that in subacute group and acute group(P<0.05).The ratio of strain in subacute group was higher than that in acute group(P<0.05). Conclusion:Ultrasound elastography deep venous thrombosis has a positive value stage to evaluate the hardness variation in different periods of venous thrombosis.
