capillaries, less than 2 mm in diameter. They may be
red, blue or purplish in color, visible as short, unconnected
lines each about the size of a large hair. They may
appear as sunburst pattern, or they may resemble a spider
web or tree with branches. In some people, they occur
in a small area and are not particularly noticeable.
In others, they may cover a large area of skin and be
to 80% of varicose veins are accompanied by some form
of spider veins. Spider veins may exist without the
presence of significant varicose veins.
