Spider veins, also known medically as telangiectasia or
venulectasias, are the mildest manifestation of venous insufficiency, similar to
varicose veins but smaller. They are small, often tangled groups of tiny blood
vessels just under the skin surface that frequently resemble spider webs or tree
branches. They are generally red, blue or purple and are clearly visible,
usually on the thighs, lower legs and face. Spider veins can sometimes cover
large areas of skin, but they are a cosmetic problem only, rarely causing
physical symptoms. At least a third of all women and a smaller percentage of men
are believed to display the condition.
Spider veins are thin vessels directly
connected with the larger venous system, and like varicose veins they are often
caused by venous reflux. Spider veins may be isolated or associated with
"feeder" veins or with larger underlying varicose veins, but they are not
varicose veins – they do not bulge above the skin surface and do not require
medical treatment.
Spider veins can be diagnosed merely by sight. They tend
to take on one of three characteristic patterns – a "sunburst" or spider-web
pattern radiating outward from a central point, a "tree-branch" pattern, or a
"matting" or linear pattern that may be nothing more than a set of thin lines.
Even in the absence of physical discomfort, our physicians prefer to conduct
ultrasound exams to determine the extent of the problem and the underlying
causes of the condition.
Risk factors for spider veins are similar to those
for varicose veins – age, heredity, pregnancy, hormonal changes, obesity and
extended periods of standing – as well as sun exposure, particularly in
fair-skinned people, and injuries to the skin surface. Some physicians believe
that exercise, weight loss and the wearing of support hose and flat shoes
instead of high heels can reduce the incidence of spider veins. Spider vein
treatments are non-invasive or minimally invasive and include sclerotherapy
and other innovative procedures.

Spider veins are thin surface veins that turn blue
or red under the strain of the venous reflux and affect the appearance of the
location where they occur. Spider veins are considered a cosmetic problem,
rarely causing physical discomfort, and can be addressed with a variety of
non-invasive, techniques.
