What Is Sclerotherapy?

Sclerotherapy is used for spider veins and medium “reticular” veins. A sclerosant (chemical) is injected into the unwanted vein to produce an inflammatory reaction. The inflammation will cause the vein to close and eventually wither away. The spider veins are treated with a liquid sclerosant while the reticular veins are best treated with a “foamed” version of the same sclerosant.

Highlights

  • As a general rule, the more veins present the more treatments will be required. Treatments are usually scheduled every four to six weeks until the process is complete.
  • It is best to schedule sclerotherapy during the months when your legs are covered and you may more conveniently wear your compression hose. We recommend compression hose for one to three days after treatment depending on the size of the vessels treated.
  • If large varicose veins are present along with the spider veins it is recommended that these be treated first. State-of-the-art treatment now includes endo-venous closure with heat provided by laser or radiofrequency technology.
  • The cost of the procedure is related to the amount of medication used.

Complications

We expect mild bruising and occasional tenderness at the injection sites. At times a small, harmless superficial blue clot will result from the treatment, a sure sign that the vein has closed down. The clot may be extracted using local anesthesia to improve the appearance.
