Chemical Ablation (Varithena)
Varithena is a foam sclerosant medication (Polidocanol) that is injected into the vein causing damage, scarring and eventual closure of the great (long) saphenous vein leading to its closure. Varithena foam displaces blood from the abnormal great saphenous vein or varicose veins which allows the liquid component of the foam to come into contact with the vein wall. Varithena causes the vein to swell and seal closed; over time, the vein shrinks and it reabsorbed by the body. When the malfunctioning vein collapses, blood flow shifts to healthier veins nearby. This form of treatment is called endovenous chemical ablation with ultrasound guidance.
