Abstract Objective: To evaluate the relationship between the ultrasonic features of perforating veins(PVs) and the clinical stages in patients with venous insufficiency of lower extremities. Methods: In 45 cases(50 lower limbs) with differernt clinical stages of venous incompetence of lower extremities, the number, diameter and blood flow velocity of PVs were examined by color Doppler ultrasound. Results: There were positive relationships between PVs’ number, diameter or blood flow velocity and the clinical stages, with a relationship index of 0.48, 0.55 and 0.51, respectively(P<0.05). Conclusion: Higher clinical stages were accompanied with greater number, wider diameter or faster blood flow of PVs.
