Varithena™ (Polidocanol Injectionable Foam)
Varithena is an injectable foam medication used to treat the great saphenous vein (GSV), the anterior saphenous vein (ASV), and larger veins connected to the saphenous systems. Using ultrasound guidance the foam is administered through a catheter or by direct injection into the malfunctioning vein. The foam fills the desired section of the vein and treats the vein wall, causing the diseased vein to collapse. The blood flow is then redirected into healthier nearby veins. The procedure takes approximately 20-30 minutes and is minimally invasive.
