What are Spider Veins?

Spider veins are small, thin veins that lie close to the surface of the skin. These dilated vessels, properly named telangiectasias, are small red, blue, or purple web-like veins on the surface of the skin. They can most commonly be found on the thighs, calves, ankles, or face, and often become a cosmetic concern. The primary factors contributing to their development include heredity, pregnancy, hormones, weight gain, and prolonged standing or sitting. Spider veins typically occur more frequently in women.

Symptoms

Spider veins are usually harmless, though they can cause significant discomfort, particularly in the legs after prolonged standing. Although spider veins are cosmetic and do not pose health risks, they are generally felt to be unsightly and cause feelings of self-consciousness. Some people may experience symptoms including aching, itching, burning, and heaviness. Treating these veins early could prevent worsening symptoms associated with venous reflux disease.

Treatment

Sclerotherapy is the method of eliminating spider veins in which a solution, called a sclerosing agent, is injected into the veins. This causes an irritation to the inner lining of the vein, resulting in its closure. The procedure can last up to 30 minutes per session and each vein may require more than one injection. Some results may be seen immediately; while others may take weeks or even months. Following sclerotherapy, the leg must be supported to keep the veins closed. This is accomplished by using compression bandages or graduated support stockings. These stockings look just like tall socks and cause minimal discomfort.

Not all spider veins require treatment, particularly if they are not causing pain or other physical symptoms. However, some people decide to have them treated for cosmetic reasons. An estimated 1.7 million patients now undergo sclerotherapy each year in the United States.
