Clinical value of color Doppler ultrasound in the diagnosis of lower extremity varicosis of great saphenous vein in patients with deep vein structure and hemodynamic status

Objective To investigate the clinical value of color Doppler ultrasound in the diagnosis of lower extremity varicosis of great saphenous vein in patients with deep vein structure and hemodynamic status. Methods 79 patients with 96 deep lower extremity varicosis were detected deep venous wall and valve echo, lumen morphology, reflux time, reflux velocity and spectrum Doppler imaging by using color Doppler ultrasound, and the results were compared with intravenous X-line angiography, while the patients with normal deep vein were selected as the control group. Results Color Doppler ultrasonography compared with angiography, the completely normal diagnostic accuracy of deep vein was 98.3%, the diagnosis accuracy of simple deep venous valve insufficiency was 91.7%, the diagnostic accuracy of sequela of deep vein thrombosis was 100.0%, the diagnosis accuracy of arteriovenous fistula was 100.0%.The sonographic appearance of 60 deep veins was similar to those of the control group.In the stripping surgery of 60 great saphenous vein, there was no postoperative lower limb swelling, review of ultrasound had no deep venous reflux phenomenon.96 suffered limbs were measured in different parts, different levels of venous reflux.The reflux time of superficial femoral vein valve was the longest, which was (5.92±1.83)s, the reflux rate was (50.28±19.48)cm/s, and the lower leg traffic vein reflux time was the shortest, which was (2.37±1.92)s, the reflux rate was (27.92±17.28)cm/s. Conclusion Color Doppler ultrasound has important clinical value for the evaluation of lower extremity varicosis of great saphenous vein in patients with deep vein structure and blood flow.
