 What
are spider veins?
Spider veins are small, thin
veins that lie close to the surface of the skin that are usually red or
blue in color. They commonly occur on the legs,
but are also found on the face or other areas of the body. These dilated
blood vessels may be short, unconnected lines, each about the size of
a large hair, or connected in a "sunburst" pattern. They may
look like a spider web or a tree with branches. Spider veins can occur
in a small
area where they are not very noticeable, or they can cover a large area
of skin and be very unattractive.
What causes them?
The cause of spider veins is not completely known. Heredity seems to play
a large part, but there are other possible factors such as sun exposure,
hormone changes, pregnancy and weight gain. They may also appear in areas
where tight clothing is worn repeatedly, especially if it is held in place
by strong elastic material.
How is the treatment performed?
Brief but intense emissions of light from the laser will be used to
remove the superficial blood vessels at precisely controlled levels
of penetration. During the treatment, you may hear the laser zapping,
and smell smoke. Afterward, the treated area will be covered with an
antibiotic ointment to eliminate any surface bacteria.
How long does it take?
The amount of time varies from fifteen minutes to one hour or more, depending
on the size of the area being treated and the severity of the problem.
Is it painful?
You may feel a slight burning or stinging sensation as the laser penetrates
your skin. Anesthesia is not required.
What are the after effects?
You may experience some redness and swelling of the treated area that
normally disappears within a few days. The veins usually will turn
a purple color that resembles a small bruise, and then gradually fade
within 5-10 days. Your doctor will advise you on ways to minimize after
effects.
How long does it take for them to disappear?
Recovery times depend on the extent of the treatment and the individual’s
capacity to heal. Some redness or purple discoloration may persist
for several weeks, or longer. The redness will gradually lighten to
a pink tone, and then to a lighter, more natural color. You may need
follow-up treatments to completely eliminate spider veins in a particular
area.
