Spider veins, or telanglectasias of the legs, are small purple or red veins that can form anywhere on the legs from the ankles to the top of the thighs. They affect primarily women and may be genetic, affecting several women in the same family. Spider veins do not pose any major health problems but may cause discomfort. Many people find them unsightly and attempt to cover them with clothing or cosmetics.

Aside from the genetic tendency, spider veins may be caused by trauma to legs from blows or falls, extended periods of standing or sitting, pregnancy, weight gain, or hormonal changes.

Nearly all (95%) of patients experience no adverse reactions to Sclerotherapy, but some minor side effects have been reported. These include slight blistering when small amounts of the saline solution seep into the surrounding skin. This blistering heals quickly but may result in a small freckle-like pigmentation at the injection site. These spots usually resolve with time or may be treated with bleaching agents. Bruising will occasionally occur when the veins are unusually weak but should disappear in several weeks. Sometimes a clot develops at the injection site. This is not a major cause for concern, but removal of the clot within 2 weeks will allow the healing process to progress normally. Swelling may occur in patients who stand or sit for long periods of time. Although not dangerous, the swelling should be treated with elevation of the legs and/or compresses.

Multiple veins can be treated at the same session, but many veins require more than one injection, and repeat injections are done 1 to 2 weeks after healing. The vessels disappear over a period of 2 weeks to 4 months. Your body requires up to 6 months to resolve this condition. Your patience is important!
