Objective This paper aims to analyze the clinical value of color Doppler ultrasound in the diagnosis of lower extremity venous thrombosis. Methods A total of 100 patients treated in our hospital from January 2022 to June 2024 were selected as the research subjects, including 50 patients with lower extremity venous thrombosis and included in the study group, and the other 50 patients who did not have lower extremity lesions were included in the reference group. Both groups of patients were given color Doppler ultrasound diagnosis, and the color Doppler blood flow imaging values of the two groups were statistically analyzed. The test results of the two groups were compared to judge the diagnostic effect. Results The blood flow imaging values of the two groups were compared. The values of the bilateral common femoral vein, superficial femoral vein, popliteal vein, and calf intermuscular vein in the study group were lower than those in the reference group (P < 0.05). Conclusion In summary, color Doppler ultrasound has important clinical application value in the diagnosis of lower extremity venous thrombosis. By providing quantitative information such as venous inner diameter and blood flow imaging values, as well as standardized operations and careful observations, it provides an important basis for the diagnosis of lower extremity venous thrombosis and also provides strong support for the treatment of patients.
