Sclerotherapy Treatment

Look better, feel better.

What is Sclerotherapy?

Sclerotherapy 101

Sclerotherapy is a safe, proven medical procedure that treats both the symptoms and the cause of varicose veins and spider veins. Sclerotherapy treatment sessions usually take less than half an hour, with no hospitalization required. Most patients do not find sclerotherapy treatments to be particularly painful, and recovery time is generally very short—most people are back to their regular routine the same day.

For sclerotherapy treatments, a series of microinjections of a solution (“sclerosant”) are administered directly into varicose veins or spider veins. Watch the video below on how ultrasound-guided sclerotherapy treats varicose and spider veins.


This non-invasive, outpatient procedure uses a mild chemical solution, called a sclerosant, to treat spider veins and varicose veins. In some cases, ultrasound may be used to guide the injection.

Injecting the Sclerosant

After the area is cleansed and sterilized, the physician inserts a needle into the target vein and injects the sclerosant. In cases of spider veins, the physician may treat the feeder vein, which supplies blood to the visible branches.

Vein Collapse

The sclerosant irritates the wall of the blood vessel, causing it to restrict and collapse. The flow of blood will be redirected to other healthy veins in the area. The physician may make multiple injections along the target vein to complete the treatment. Over time, the body will absorb the collapsed vein.

End of Procedure

The leg is bandaged tightly for several hours to help keep the treated vein closed. Patients will be able to return to normal activities immediately after the procedure. Compression hose may need to be worn for several days after the procedure.


Rerouting blood flow to healthy veins.

The word sclerotherapy has Greek origins–“sclero” means hardening, scarring, or drying up, and that’s essentially what sclerotherapy does to unhealthy veins. The injected solution acts to close off the vein with abnormal valves, sealing it off from your other, healthy veins. Over time, the treated veins shrink and are eventually absorbed by your body. Your blood flow, meanwhile, naturally reroutes itself into your healthy veins, improving your circulation and eliminating the root cause of your vein disease.

Real Patients, Real Results

I had some veins on my calf that were swollen and ugly looking. With the procedures I had done, those ugly veins are gone! I also had more work done on both of my legs. I am so happy with the results. Took 20 years off my legs!


Varied sclerotherapy treatment for varied patient needs.

Your treatment may or may not involve ultrasound to either map your venous system for diagnosis or to guide the sclerotherapy process itself. The technology can provide a live view of your veins, allowing the physician to inject the sclerosant into precise locations to achieve the best results. Physicians usually utilize ultrasound-guided sclerotherapy to treat larger varicose veins. For smaller spider veins closer to the skin’s surface, ultrasound guidance is usually not necessary and visual inspection is sufficient.

Sclerotherapy may be used on its own or in conjunction with endovenous thermal ablation (EVTA). Your vein specialist will customize a treatment plan designed to improve your health and allow you to return to your active lifestyle as quickly as possible.
