Abstract

Treatment decision of varicose veins should be made based on the patient’s symptoms, but it is important to confirm the presence of reflux when selecting a treatment method. The definition of reflux, which is the core of ultrasound diagnosis of varicose veins, is recommended as follows. In the case of the great saphenous vein, anterior and posterior accessory saphenous vein, small saphenous vein, perforating vein, tibial vein, and deep femoral vein, reverse flow of more than 0.5 seconds is considered as reflux. In the case of the common femoral vein, femoral vein, and popliteal vein, reverse flow of more than 1.0 seconds is considered as reflux. In cases of reticular veins, spider veins, and telangiectasia, because the clinical significance of measuring reflux through ultrasound has not yet been proven and they are often observed regardless of saphenous vein reflux, ultrasound diagnostic criteria are not provided.
