role of doppler ultrasound in the management of chronic venous insufficiency of the lower limb

ABSTRACT

The role of the Doppler flow meter in the management of chronic venous insufficiency was assessed by comparing its results with those of venography. The two main parameters were the detection of venous incompetence and obstruction. The sensitivity of the Doppler to detect patency of the deep system was 100% for the femoral vein. 95.5% for the popliteal vein and 77.79%.for the posterior tibial vein. The sensitivity to detect incompetence of the saphanofemoral junction and the below knee perforators were 75% and 94.1% respectively. By identification of obstruction and incompetence of the deep system, with a high degree of accuracy it aided in the differentation between primary and secondary varicose veins.This is important since the management of both conditions are different
