Sclerotherapy involves injections of a specialized sclerosing agent which collapses the veins, causing them to fade away. It normally encompasses a series of treatments spaced about four to six weeks apart to achieve optimal results. Additional veins may develop over time and thus maintenance treatments may be needed.

A sclerotherapy session takes about twenty minutes during which time a series of injections are made into the unwanted veins. After treatment, tight fitting support hose are recommended to be worn for a period of time. Walking is encouraged in the post operative period. It is common for the treatment area to look worse before it improves, with bruises and brown discoloration. Once the compression dressings are removed, you will notice bruising and reddish areas at the injection sites. The bruises will diminish over time, usually within a month. In some cases, there may be some residual brownish pigmentation which may take up to a year to completely fade.
