Varithena® is the first and only Health Canada approved microfoam procedure for the treatment of varicosities of the great saphenous vein (GSV). Varithena® is designed to treat problems that exist within the larger-diameter veins of the GSV system, for veins above and below the knee of any shape. Varithena® is for use in adults with significant venous reflux that has been diagnosed by a duplex ultrasound.
How does Varithena® work?
Varithena® is injected directly into the varicose veins. It pushes the blood out of the vein and the active ingredient (polidocanol) irritates the lining (endothelium) of the vein. This causes the vein to go into spasm, thereby destroying the endothelium which closes the vein. Over several months, the vein is slowly resorbed by the body and eventually turns into a thin string of scar tissue. The blood is redirected to healthy veins.
The Varithena® Treatment Process
01: Treatment with Varithena® does not require an incision, sedation or general anesthesia. 02: A trained physician will inject Varithena® into the affected veins of your leg (a local anesthetic to numb the injection site may be used). 03: The amount of Varithena® injected is carefully controlled by your physician through the use of ultrasound to ensure that the foam has filled the veins being treated. 04: When the veins are filled, the treatment is complete (this will depend on the size and extent of your varicose veins). After Varithena® has been administered, bandages will be applied to the injection site(s) and a compression stocking will be applied.
