Sclerotherapy is one of the most prevalent treatments for spider and varicose veins (leg veins). It is also performed to treat symptoms caused by these conditions, such as aching, swelling and burning. During the treatment, a sclerosing agent is injected into the vein through a tiny needle. Treatment can last from 15 minutes to 45 minutes, depending on the number of veins treated in a particular session. Upon injection, the solution replaces the blood in the vein, generating irritation and corrosion to the walls of the vessel. During the consultation, you will be advised by Dr. Mani as to the number of treatments necessary to achieve desired results.
