超声诊断在下肢静脉血栓及后遗症的实用价值

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4H4例急性下肢静脉血栓，16例慢性下肢静脉血栓及血栓后遗症患者进行检查，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。结论左下肢静脉血栓发病率明显高于右下肢。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，彩色多普勒超声诊断下肢深静脉血栓形成无创、准确、高度敏感，是诊断下肢静脉血栓的首选方法。

Ultrasound diagnosis of deep venous thrombosis and in the aftermath of the practical value

Objective To investigate the two - dimensional and color Doppler ultrasonography for diagnosis of deep venous thrombosis. Methods Methods of two - dimensional and color Doppler ultrasound for 44 eases of acute deep venous thrombosis, 16 patients with chronic deep venous thrombosis and thrombosis in patients with sequelae of inspection, observation of blood vessel diameter, the scope of thrombosis, blood clots and blood flow echo characteristics of the situation. Results The outcome of acute deep venous thrombosis after vascular diameter significantly widened, thrombosis manifested as homogeneous hypoehoie images echo chronic thrombeembolic higher parts of the lumen without thrombosis or blood flow showed filling defect and secondary deep vein valve function incomplete. Conclusion Left the incidence of deep venous thrombosis was significantly higher than the right lower extremity. Color Doppler ultrasonngraphy can not only diagnose deep venous thrombosis, at the same time can be observed through dynamic evolution of the clinical treatment to determine the effect of color Doppler ultrasound diagnosis of deep venous thrombosis of non - invasive, accurate and highly sensitive, is the diagnosis of lower extremity the preferred method of venous thrombosis.
