What are Spider Veins?
Spider veins – known in the medical world as telangiectasias or sunburst varicosities – are small, thin veins that lie close to 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.
A number of factors contribute to the development of spider veins, including heredity, pregnancy and other events that cause hormonal shifts, weight gain, occupations or activities that require prolonged sitting or standing, and the use of certain medications.
Spider veins usually take on one of three basic patterns. They may appear in a true spider shape with a group of veins radiating outward from a dark central point; they may be arborizing and will resemble tiny branch-like shapes; or they may be simple linear and appear as thin separate lines. Linear spider veins are commonly seen on the inner knee, whereas the arborizing pattern often appears on the outer thigh in a sunburst or cartwheel distribution.
Spider vs. Varicose Veins
Varicose veins differ from spider veins in a number of ways. Varicose veins are larger – usually more than a quarter-inch in diameter, darker in color and tend to bulge. Varicose veins are also more likely to cause pain and be related to more serious vein disorders.
Spider Vein Treatments
Spider veins, unfortunately are a lifelong battle for most patients. Even after successful treatment, the body tends to continue producing them. For this reason, most patients need intermittent maintenance treatments to keep their legs vein free. Spider vein treatments are done for cosmetic reasons and are not covered by most insurance carriers
Sclerotherapy can enhance your appearance and your self confidence, but it’s unrealistic to believe that every affected vein will disappear completely as a result of treatment. After each sclerotherapy session, the veins will appear lighter. Two or more sessions are usually required to achieve optimal results.
You should also be aware that the procedure treats only those veins that are currently visable; it does nothing to permanently alter the venous system or prevent new veins from surfacing in the future.
