• Sclerotherapy: This procedure involves the injection of a liquid or foam chemical directly into the vein with a small needle. The chemical, called a sclerosant, irritates the veins and causes it to collapse. Over time, the vein turns into scar tissue that fades away. The procedure is usually done in a clinic, is relatively inexpensive, and has little downtime. Most individuals require a couple of sessions to treat all the spider veins. Side effects of sclerotherapymay include slight swelling, bruising, and redness and itching at injection sites. If the solution leaks out of the vein, pain and darkening of the skin occurs.
  • Surgical ligation/stripping: Spider veins are almost never treated with surgery. Surgery is only reserved for the large varicose veins.
