Visual and Ultrasound Guided Sclerotherapy
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.
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. For some patients, sclerotherapy can be used to treat varicose veins. However, often surgical treatment is necessary for this condition.
You may need anywhere from one to several sclerotherapy sessions for any vein region. Depending on the type and number of veins being treated you may have one to many injections per session. Generally, normal activities can be resumed after sclerotherapy. Medically prescribed support hose and/or bandages may need to be worn for several days to several weeks to assist in resolution of the veins. The procedure, performed in the doctor's office, usually causes only minimal discomfort. Bruising and pigmentation may occur after sclerotherapy. Bruising typically disappears within 1-2 weeks. Although pigmentation almost always fades, it can last for several months. Scarring and other complications are rare.
