下肢深静脉血栓的超声诊断价值及相关诊断方法的应用

目的 研究下肢深静脉血栓的超声诊断价值及相关诊断方法的应用。方法 选取2018年5月~2019年5月在我院诊治的132例下肢深静脉血栓患者临床资料，患者均采用常规超声和多普勒超声检查，比较两种诊断方法下肢静脉血栓的检出率、不同节段下肢静脉血栓灵敏度。结果 彩色多普勒超声检查下肢深静脉血栓检出率为96.21%，高于常规超声检查的80.30%，差异有统计学意义（P＜0.05）；彩色多普勒超声检查不同节段下肢深静脉血栓（股静脉、髂总静脉、腘静脉、胫后静脉、胫前静脉）灵敏性、特异性查比较，差异有统计学意义（P＜0.05）；彩色多普勒超声对股静脉（96.66）、腘静脉（92.59）的灵敏性较高，对髂总静脉、胫后静脉、胫前静脉的灵敏性较低。结论 下肢深静脉血栓采用彩色多普勒超声检出率高，且对出不同节段深静脉血栓灵敏性存在差异，无创伤，具有良好的重复性，有一定的的诊断价值。

Ultrasound Diagnosis Value of Lower Extremity Deep Venous Thrombosis and Application of Related Diagnostic Methods

Objective To study the value of ultrasonography in the diagnosis of deep venous thrombosis of lower extremities and the application of related diagnostic methods. Methods The clinical data of 132 patients with deep venous thrombosis of lower extremity who were treated in our hospital from May 2018 to May 2019 were selected. The patients were compared with conventional ultrasound and Doppler ultrasonography. The detection rate of lower extremity venous thrombosis was compared between the two diagnostic methods. Sensitivity of lower extremity venous thrombosis in different segments. Results The detection rate of deep venous thrombosis of lower extremity by color Doppler ultrasonography was 96.21%, which was higher than 80.30% of conventional ultrasonography,the difference was statistically significant (P<0.05). Color Doppler ultrasonography was used to detect deep venous thrombosis of lower extremity in different segments. The sensitivity and specificity of the femoral vein, common iliac vein, iliac vein, posterior tibial vein and anterior tibial vein were statistically significant (P<0.05) ;Color doppler ultrasound has a higher sensitivity to femoral vein（96.66） and popliteal vein（92.59）, and a lower sensitivity to common iliac vein, posterior tibial vein and anterior tibial vein.Conclusion The detection of deep venous thrombosis of lower extremity is high by color Doppler ultrasound, and there is a difference in sensitivity to different segmental deep vein thrombosis. It is non-invasive, has good repeatability and has certain diagnostic value.
