Spider veins named for their resemblance to a spider or spider web, spider veins are a mild variation of varicose veins. They are the small, thread-like colored veins that are most often seen on the surface of the skin. Venules (tiny blood vessels) near the skin’s surface may become permanently dilated because of the pressure of blood inside leg veins. While many people seek treatment for spider veins for cosmetic reasons, spider veins also can result in substantial discomfort requiring therapy.
Sclerotherapy is a treatment for the removal of spider veins and smaller varicose veins. A small volume of a sclerosing liquid is injected into the diseased vein, which causes it to seal shut, eliminating the vein completely. Sclerotherapy is a quick in-office procedure and does not require any anesthesia.
Blood circulation is carried out through healthy veins located deeper within the body, so the outward appearance and sometimes pain associated with the problematic veins is significantly reduced.
