【摘要】 目的 探讨二维及彩色多普勒超声检查对下肢静脉血栓的诊断价值。方法 应用二维及彩色多普勒超声对55例下肢静脉血栓患者进行检查,观察血管内径、血栓范围、血栓回声特征及血流情况。结果 急性下肢静脉血栓形成后血管内径明显增宽,血栓表现为均质低回声图像,慢性血栓回声较高,血栓部位管腔无血流显示或血流充盈缺损,并可继发深静脉瓣功能不全。 结论 彩色多普勒超声检查不仅可诊断下肢静脉血栓,同时可通过动态观察其演变情况,判断临床治疗效果,是诊断下肢静脉血栓的首选方法。

    【Abstract】 Objective To study theclinical value of the two dimensional and color Doppler ultrasound examination in the diagnosis of deep vein thrombosis.Methods Two dimensional and color Doppler ultrasound in 55 cases of deep vein thrombosis patients were examined blood vessel diameter,the scope of thrombosis,thrombosis echo characteristics and blood flow.The results of acute deep venous thrombosis after the vessel diameter was obviously enlarged,thrombosis showed homogeneous low echo images,chronic thromboembolic echo the higher parts of the lumen without thrombosis,or blood flow showed filling defect and could be secondary to deep venous valve function incomplete.Conclusion Color Doppler ultrasound examination can not only diagnose deep vein thrombosis,while a dynamic observation of its evolution,to determine clinical effects,the diagnosis of deep venous thrombosis of the preferred method. ......
