Video Overview

What is the difference between ultrasound guided sclerotherapy and visual sclerotherapy? Visual therapy is injection of sclerosants or solutions into smaller surface varicose veins. Those are the veins seen by the naked eye, such as your spider and your reticular veins. Duplex guided sclerotherapy is the injection of sclerosants usually in the larger diseased superficial veins not seen on the surface such as your truncal veins and their tributaries. All sclerosants work by irritating the lining of the vein wall. In response, the veins collapse and are reabsorbed by the immune system.
