彩色多普勒超声在下肢深静脉栓塞诊断中的应用价值

目的探讨彩色多普勒超声诊断下肢深静脉血栓(DVT)的应用价值。方法彩色多普勒超声对212例临床怀疑DVT的患者进行血管超声检查,观察双下肢深静脉的走行、管径、血管内壁、管腔内透声及血栓回声特征。结果彩色多普勒超声明确诊断201条深静脉血栓形成。彩超表现为患肢深静脉管径增宽,管腔内可见絮状弱回声、实质低回声或不均匀低弱回声,管腔结构不清,探头轻压不能闭合,病变部位无彩色血流信号或可见狭窄细条状的彩色血流信号。结论彩色多普勒超声能及时诊断急性DVT,为临床提供及时、准确、安全、无创的检查手段,对早期诊断、指导治疗、减少并发症具有重要的临床应用价值。

Value of color Doppler ultrasound in the diagnosis of deep venous thrombosis of the lower limbs

Objective To evaluate the value of color Doppler ultrasound in the diagnosis of deep venous thrombosis of the lower limbs. Methods A total of 212 cases clinically suspected as deep venous thrombosis of the lower extremity were examined with color Doppler ultrasound. The anatomic tracing, diameter, wall, intraluminal echogenicity and thrombosis echogenicity of the deep veins of the lower extremity were observed. Results Totally, 201 deep veins were diagnosed as thrombosis by color Doppler ultrasound. The features of thrombosis on ultrasound were enlarged diameter of vessels, intraluminal dim, hypoechogenic or heterogeneous weak echogenicity, undistinguishable vascular structure, and incompressible vein under slight compression with probe. Color Doppler ultrasound revealed the absence of blood flow or slender blood flow signal in veins. Conclusion Color Doppler ultrasound is valuable in the diagnosis of deep venous thrombosis of the lower limbs. It is an accurate, safe, non-invasive and convenient method in early diagnosis, treatment and reducement of the complications clinically.
