Sclerotherapy

Sclerotherapy is a technique that is mainly used to treat spider veins or smaller, surface varicose veins less than 1-2mm in diameter. Sclerotherapy is one of the most effective treatments for spider veins.

A sclerosing solution is injected into the vein at various intervals, irritating the lining of the vein. The vein lining then swells and sticks together, effectively closing up the vein. Sclerotherapy can be uncomfortable for brief periods. As the solution replaces the blood in the veins, there will be a cramping sensation for 1 to 2 minutes.

Sclerotherapy usually takes 30 to 45 minutes, and may require multiple sessions. In general, spider veins respond to treatment in one to two weeks. The body eventually absorbs the fibrous tissue of the former vein.

With the use of compression stockings, the patient can resume normal activities the next day.
