In sclerotherapy treatments, a series of microinjections of a solution (“sclerosant”) are administered directly into varicose veins or spider veins. The injected solution closes off veins with abnormal valves. Over time, the treated veins shrink and are eventually absorbed by your body. Blood flow naturally reroutes itself into healthy veins, improving circulation and eliminating the root cause, as well as the symptoms of vein disease.
Treatment may or may not involve ultrasound to either map your venous system for diagnosis or to provide a live view of your veins. Physicians usually utilize ultrasound-guided sclerotherapy to treat larger varicose veins. For smaller spider veins closer to the skin’s surface, ultrasound guidance is usually not necessary and visual inspection is sufficient.
