Spider Veins are small superficial blood vessels that appear red or blue in the skin. They commonly occur on the legs, but are also found on the face or other areas of the body.
How are unwanted blood vessels on the legs treated?
The injected method is a procedure called sclerotherapy. This procedure has been used for spider veins since the 1930’s, and before that for larger veins. Hypertonic Saline is injected directly into the blood vessels with a very fine needle. The solution irritates the lining of the vessels causing it to swell, stick together, and the vessel to collapse. Over a period of weeks, the vessel turns into scar tissue that fades, eventually becoming barely noticeable. A single blood vessel may have to be injected more than once, some weeks or months apart, depending on its size. A number of vessels can be injected in any one-treatment session.
The best time to have this procedure is during the fall and winter since sun exposure after the treatment can darken (hyperpigment) the treated vessels. Another reason for having the procedure done during the cooler months is due to the compression stockings worn for several weeks after the treatment. This is required to improve the outcome.
