Sclerotherapy Spider Vein Treatment

Dr. Zengo has 15 years of experience treating cosmetic spider veins. We never use painful saline and always identify feeder veins with powerful transillumination mapping.

Are you tired of trying to hide your unsightly varicose veins or unattractive spider veins under a long dress or pants?

Do you avoid wearing shorts or a bathing suit because of how they make you feel?

If you answered yes to any of these questions, you’re not alone. In fact, you share the same frustrations that at least half of the adult female population in the U.S. endures everyday when it comes to their legs.

Sclerotherapy has been practiced worldwide for decades.  In the last 20 years, we’ve seen the greatest advances in Sclerotherapy technique and agents.  Sclerotherapy involves the use of a series of very fine injections of a solution directly into the affected veins. This therapeutic liquid solution causes the affected veins to first swell, then collapse and slowly fade away over a few weeks or a few treatments.  This is even less painful, and more accurate than laser treatments.

This therapy is performed in our office on an outpatient basis with the largest and slightly deeper veins being treated first.  A typical therapy session lasts about 30 minutes with patients needing 3-6 treatments to get the best results.

Foam Sclerotherapy with Transillumination


Older sclerotherapy treatments were painful. The needles were stiff and the solutions very caustic. Many people had side effects. Now, we have discovered weaker, yet more effective agents that can close the veins nearly painlessly!  Also, thinner, more flexible needles are used that are barely noticeable.  We have had numerous patients fall asleep during their sclerotherapy treatments!

For the deeper reticular veins, we use illumination to identify and treat the veins that feed the spider complexes. This device is called the Veinlite and results pinpoint accuracy and complete visualization of the treated veins.  The spider veins that are fed by this invisible, deeper feeder then begin to lighten without needing to be injected themselves.

Spider Vein Sclerotherapy FAQ's

A:  Sclerotherapy can successfully treat large and small non-bulging veins. In fact, studies show 85% of all vein problems can be successfully treated with Sclerotherapy alone.  We offer a no-charge consultation to evaluate your legs and estimate the number of treatments you might need.  If you are pregnant or breastfeeding, you should postpone Sclerotherapy treatment until you given birth and have stopped breastfeeding.

A:  Because there are many veins in the leg, after the affected veins are closed, the blood  simply flows through other healthy veins after the procedure. Therefore, the loss of the diseased vein is not a problem for the body.  In fact, Sclerotherapy is not only cosmetic “maintenance” but it also improves circulation, with many patients noticing an improvement in leg heaviness and discomfort because the dysfunctional veins are no longer hindering blood flow.

A:  Treated veins should not reappear after a successful series of treatments 4-6 weeks apart. However for many patients, spider veins are a recurring problem and treatment will not prevent new veins from emerging in other areas in the future. Therefore, to help reduce the formation of new veins, regular exercise including walking, jogging and bicycle riding has been found to promote healthy circulation and also slows the development of new varicose and spider veins.  There are other things you can do to promote good leg vein health, including:

  • Maintain ideal body weight
  • Eat a high fiber diet to prevent constipation
  • Explore natural alternatives, such as Massage Therapy and dietary supplements (vitamins C and E, for instance, may help relieve swelling and other symptoms of poor circulation)
  • Avoid crossing your legs for extended periods of time

Although these measures are the best defense against the spread or development of new vein problems, we cannot alter the causes of your vein problems nor can we avoid heredity or aging. Therefore, as time passes, you may find that you need “touch-ups” for new veins that surface.

A: The number of treatments needed varies greatly from patient to patient and depends on the severity of your condition.  On average, at least 3-4 visits are usually required. Almost nobody will benefit from just a single vein treatment. On most occasions, veins are narrowed but not completely closed in the first treatment. The follow-up visits every 4-6 weeks will further close down the veins for good!

A:  First and Foremost, you will need to avoid direct sun exposure and tanning beds until the legs are healed.  Baking injection sites in the sun while they are healing can lead to a brown pigment called staining that is sometimes permanent.  You should walk and use your legs but wearing Class 1 Compression Stockings for one week will make your treatments even more effective.  If you do not own any of these stockings, we can keep them in stock in our office.
