Abstract

Objectives: To describe the imaging characteristics of venous lesions of the lower extremities on Doppler ultrasound in patients with chronic lower extremity venous insufficiency at Thai Binh Medical University Hospital. Method: Cross-sectional study; 96 patients were collected - sample size was calculated according to descriptive study. Results: For the superficial venous system, patients with great saphenous venous insufficiency accounted for the highest proportion (33.3%). The proportion of patients with both saphenous venous insufficiency was 24.0%. At stage C4, 5, 6, the mean diameter of the femoral, popliteal was significantly larger than that of stage C1, 2, 3 (p<0.05). There were 3 patients with thrombosis, accounting for 3.1%; patients without thrombosis accounted for 96.9%. Patients with venous reflux flow from 3 to 5 seconds accounted for the highest proportion (47.9%). The proportion of patients with venous reflux flow over 5 seconds accounted for 7.3%. Conclusion: Chronic venous insufficiency of the lower extremities in the superficial venous system is mainly insufficiency of the great saphenous veins; the mean diameter of the veins of the femoral, popliteal and lower legs at stage C4, C5, C6 is significantly larger than at stages C1, C2, C3.
