“A regular skin checkup can literally save your life.” Jennifer Krasnoff, MD

What causes spider veins?
The exact cause of spider veins is unknown. Certain families are predisposed to this condition, particularly female relatives. Certain things are believed to make spider veins worse: estrogens, pregnancy, and birth control pills, tight girdles or garter belts, prolonged standing or sitting and trauma.

How does sclerotherapy work and what solution is used?
In this office, hypertonic saline, sotradecol or polidocanol solution is used to treat the veins. These solutions work by damaging the blood vessel lining, without damaging the surrounding tissues.

How soon will the vessels disappear and how many treatments will I need?
Each vessel usually requires 1-3 treatments. The vessels disappear over a period of 2 weeks to 3 months but can continue to fade over 6 months. Recurrences may rarely occur over a period of 1-5 years. This treatment does not prevent new telangectasias from developing.

Are there certain vessels which tend to occur more commonly?
Yes. They are the type of vessel which occur in a mat of very fine radiating vessels.

How often can I be treated?
The same area should not be injected for 3-4 weeks to allow for healing. Different areas may be treated every week.

Are there certain kinds of veins that can not be treated?
Large varicose veins may not respond to sclerotherapy alone and may require a minor surgical procedure. You may be referred to a vascular surgeon for treatment of the larger varicose veins.

Is there a way to prevent spider veins?
Support hose, weight reduction and regular exercise may help.

What are the side effects?

  • Bruising is common and can last for weeks.
  • Pain, itching or redness around the injection site may occur.
  • Hyperpigmentation occurs at the injection site in 10-30% of individuals. This usually resolves in 80% of people within 3-6 months and in few patients can last for 1 year.
  • Telangiectatic matting is the development of tiny vessels or a blushed area and may occur at the edge of the treated area.
  • Sores or ulcers may rarely occur around the injected vessel, but usually resolve in a few days. However, this can lead to scarring.
  • Clotting may rarely develop. It occurs more commonly if support stockings are not worn properly. Rarely, blood clots in the legs can travel to the lungs, especially if you have certain blood vessel diseases.
  • Swelling over the injection site may occur, especially after prolonged standing.
  • Superficial Thrombophlebitis, an irritation around the injected vessel, occurs in less than 1/1000 patients.
  • Mild systemic reactions have been reported and include headache, nausea and vomiting.
  • Allergic reactions such as, hives, asthma, hay fever and rarely anaphylactic shock and death have been reported.
