Vein Specialist located in New York, NY

If you're tired of gnarled, enlarged varicose veins, you may consider sclerotherapy. Often considered the treatment of choice for small varicose veins, sclerotherapy collapses the affected vein, significantly reducing how visible it is.

Sclerotherapy Q & A

What causes varicose veins?

To return to your heart, blood must travel against gravity as it flows up the veins in your legs. Muscle contractions push blood upward, but tiny valves in the veins ensure it moves in the right direction. The valves open to let blood flow up the vein, then close to stop it from going down.

When a valve is weak or damaged, however, blood flows backward and accumulates in the vein below the valve. This condition, called chronic venous insufficiency, causes varicose veins.


Varicose veins may cause symptoms such as pain, itching, and achy or tired legs. The enlarged veins are also associated with serious complications, including venous stasis ulcers and deep vein thrombosis.

What is sclerotherapy of varicose veins?

Sclerotherapy is one of the top treatments for varicose veins. During the procedure, Dr. Radwaner uses a fine needle to inject medication into the targeted veins. The medication makes the vein collapse, then a scar develops and is gradually absorbed by your body. As a result, the varicose vein disappears.

In some cases, sclerotherapy may be performed using ultrasound to visualize deep veins and to guide the placement of the needle. The number of injections you may need depends on how many varicose veins are being treated, their sizes, and whether Dr. Radwaner uses a liquid or foam medication.

What is Varithena®?

The medication frequently used for sclerotherapy, polidocanol, is available in two forms: liquid and foam. The foam, called Varithena, expands to cover a larger surface area inside the vein.


With foam as an option, Dr. Radwaner can quickly and effectively eliminate varicose veins that are severely twisted or have a large diameter. While Varithena can treat a variety of difficult varicose veins, it’s not the best option for everyone. Dr. Radwaner can recommend the type of medication for your veins after your examination.

What should I expect after sclerotherapy to treat varicose veins?

You’ll get up and walk as soon as your sclerotherapy is finished, and you can immediately return to most activities. However, you’ll need to avoid strenuous exercise until Dr. Radwaner gives you the go-ahead to resume full activities. You may also need to wear compression stockings following sclerotherapy, which helps you meet the requirement of keeping the treated area out of sunlight.
