Sclerotherapy

background

Sclerotherapy is used to obliterate spider veins or varicose veins, which can appear anywhere on the leg. The veins are injected with a concentrated salt solution (sodium chloride.)
Spider veins, also known as telangiectasias or sunburst varicosities, are small, thin veins located near the surface of the skin. Although these super-fine veins are connected with the larger venous system, they are not an essential part of it. Occasionally, spider veins appear on the face.
Varicose veins are larger (usually more than a quarter-inch in diameter), darker in color and tend to bulge more than spider veins. Varicose veins are also more likely to cause pain and be related to more serious vein disorders. Some varicose veins may require surgery or laser therapy to remove.
