Spider veins, or telangiectasias, are
those tiny purple and red blood vessels found most commonly
on the thigss or lower legs of women. They are hereditary and
can form anywhere on the leg, from the top of the thigh to the
ankle. Occasionally, spider veins appear on the face.
Varicose veins are larger. They can appear raised, with a bluish color,
and can become quite painful. Although spider veins and varicose veins
carry blood, they are not part of the venous valve system.
Spider veins are most often treated with sclerotherapy, in which a saline or chemical solution that is injected into the vein, irritating the lining and causing the vein to collapse and disappear.
In some cases, laser treatment may be used either alone or in combination with sclerotherapy.
