This is the most common treatment for both spider veins and varicose veins. Our nurse practitioners inject a solution, such as Asclera or Sotradecol, into the vein that causes the vein walls to swell, stick together, and seal shut. This stops the flow of blood and the vein turns into scar tissue. In a few weeks, the vein should fade. The same vein may need to be treated more than once.

This treatment is very effective if done the right way. Most patients can expect a 50% to 90% improvement. Sclerotherapy uses special solutions and injection techniques that increase the success rate for removal of spider veins. Sclerotherapy does not require anesthesia, and can be done in the doctor's office.

Q: Is there any pain with the procedure?

A: The injection uses a fine needle that causes a barely noticeable pinprick feeling. Some people experience a slight to moderate burning feeling immediately after the injection, but this disappears after a few seconds.

Q: What do I do after the procedure?

A: To improve the blood circulation in the deep veins, it is essential to walk after the treatment. A compression stocking is worn to reduce the risk of bruising and swelling or other complications. This may help seal the treated vessels, keep the blood from collecting under the skin, and reduce the development of dark spots. It may also reduce the number of treatments necessary, and the possibility of recurrence.

Regular exercise, weight control and the use of support stockings (if practical) are recommended between treatments and after treatments.

Q: Are there any side effects?

A: There are some possible side effects. They include:

Q: Will treated veins recur?

A: Large veins may recur even after surgical procedures. Spider veins may also recur. It may seem that a previously injected vessel has recurred when in fact, a new spider vein has appeared in the same area.
