Sclerotherapy for Spider Veins

Sclerotherapy is a non-surgical procedure that involves injecting a solution into the vein. One of the treatments is called Sotradecol and is FDA approved and has been extremely effective for over 60 years. This solution causes the walls of the veins to stick together, preventing the blood from pooling in the vein and thus forcing the blood flow from the dysfunctional vein to veins that are functioning efficiently.

Why choose sclerotherapy for spider veins

Sclerotherapy alone will be effective for spider veins and many varicose veins. In many cases with the larger varicose veins a recommendation will be to ligate, (tie off) excise or remove the larger veins. This procedure, performed by a surgeon, enhances the effect of sclerotherapy.

Again, this is a simple office procedure which we will discuss and can arrange, should it be needed. In some cases however, the vein is just too large or there are too many to remove comfortably in the office. It is best, in these few cases, that surgical removal would be best and most comfortable to the patient.

What you should know about sclerotherapy for spider veins

Treatment Options

The procedure is typically performed in the doctor’s office. It does not require anesthesia and usually takes 15 minutes to an hour to complete depending on the extent of the veins.

Patients lie on their back with their legs slightly elevated. After the treatment area is cleansed with alcohol, the doctor uses a fine needle to slowly insert a solution or foam into the vein. Some patients experience minor stinging or cramps when the needle is inserted. The injection solution or foam irritates the lining of the vein, causing it to swell shut and block the flow of blood.

Once the needle is withdrawn, the doctor will apply compression and massage the area to keep blood out of the injected vessel and disperse the solution. For large veins, a compression pad may be taped onto the site to keep the area compressed while your doctor moves on to the next vein. The number of injections depends on the number and size of veins being treated.

Possible risks

As with any treatment, there are risks associated with it,

  • Bruising
  • Raised red areas
  • Small skin sores
  • Darkened skin in the form of lines or spots
  • Multiple tiny red blood vessels

More severe complications rarely occur, including inflammation, blod clots, allergic, reaction to treatment solutions and side effects caused by tiny air bubbles in the bloodstream, including nausea, headaches, coughing and visual disturbances.


 How to prepare for the procedure

Before the procedure, our office will review the patient’s medical history and conduct a physical exam. This is the time for the doctor and patient to discuss expectations, potential risks and outcomes of the procedure. The doctor will examine the veins to be treated and check for any underlying blood vessel disorders. Be sure to let your doctor know:

  • If you are pregnant. Most doctors recommend waiting until after your delivery to perform the procedure.
  • If you have any medical conditions, such as heart disease or a pre-existing cancer or coagulation disorder.
  • About any prescription or over-the-counter medicine you are taking as well as any supplements.
  • If you smoke or take oral contraceptives, which can increase your risk of blood clots.
  • If you have any allergies.

What to expect after the procedure

  • You can stand up and walk around immediately after the procedure. It’s important to move your legs to prevent the formation of blood clots and maximize treatment results.
  • Graduated compression stockings and/or bandages are worn over the treatment area for one to three weeks to maintain pressure on the treated veins.
  • Most people can return to normal activities immediately following the procedure.
  • You should avoid sun exposure in the treatment area for two weeks following the procedure
