Clinical application of color Doppler ultrasound in venous thrombosis of the lower limbs
彩色多普勒超声在下肢静脉血栓中的临床应用

摘要

目的 给予下肢静脉血栓患者行彩色多普勒超声检查的效果和检查意义。方法 入组研究患者选自于本院近2年收治的下肢静脉血栓患者，具体时间为2020年3月1日——2022年2月28日，研究参与对象为：上述时间段内，由我院接收并实施诊疗的下肢静脉血栓患者49例（研究组），同期在我院接受体检且下肢未发生病变的患者49例（参照组），将彩色多普勒超声检查应用于所有入选患者，分析比较所得到的相关数据，进一步得出结论。结果 与参照组相比，研究组患者除腘静脉外，其他静脉内径均明显增大，分别为：股总静脉（14.33±2.26）mm、胫后静脉（4.24±0.18）mm、肌间静脉（4.16±1.25）mm、股浅静脉（9.32±1.43）mm；同时CDFI值各项数值均明显降低，分别为：股总静脉（8.16±0.87）、股浅静脉（5.94±0.75）、腘静脉（7.43±1.18）。结论 关于下肢静脉血栓患者的诊断应用彩色多普勒超声有重要意义，对患者造成的创伤更小，且无需患者承担较多的费用，检查的精准度也较为理想。

Abstract

Objective: Effect and significance of color Doppler ultrasonography in patients with lower extremity venous thrombosis..
Methods The enrolled patients were selected from patients with lower extremity venous thrombosis admitted to our hospital in recent 2 years, and the specific time was from March 1, 2020 to February 28, 2022. The participants were: The above period, received by our and implementation of 49 patients with diagnosis and treatment of lower limb venous thrombosis (research group), at the same time have a medical examination in our hospital and lower extremity lesions in patients with 49 cases (control group), color doppler ultrasound was applied to all selected patients, analysis and comparison of relevant data, the conclusion further.
Results compared with the control group, the internal diameters of all the veins except popliteal vein in the study group were significantly increased, which were: common femoral vein (14.33 ± 2.26) mm, superficial femoral vein (4.24 ± 0.18) mm, posterior tibial vein (4.16 ± 1.25) mm, and intermuscular vein (9.32 ± 1.43) mm; At the same time, the values of CDFI were significantly decreased, which were common femoral vein (8.16 ± 0.87), superficial femoral vein (5.94 ± 0.75) and popliteal vein (7.43 ± 1.18).
Conclusion   The application of color Doppler ultrasound in the diagnosis of lower extremity venous thrombosis is of great significance. It causes less trauma to patients, does not require patients to bear more costs, and the accuracy of examination is ideal.
