Sclerotherapy is a treatment widely used to effectively eliminate varicose and spider veins. During this procedure, a sclerotherapy solution will be injected directly into the unwanted vein which irritates the lining of the blood vessel and causes it to collapse, clot, and eventually be reabsorbed by the surrounding tissue. This process forces the body to redirect blood to healthier, more capable veins, causing the unwanted veins to fade away. The sclerotherapy procedure is performed with a fine needle and small amounts of sclerosing solution.
What are the side effects of sclerotherapy?
The most common side effects to sclerotherapy include allergic reactions, ankle swelling, vein inflammation or phlebitis, and in rare cases, transient hyperpigmentation. More often than not, the injected veins will become darker before disappearing due to the irritant nature of the sclerosing solution.
