PORT WINE BIRTHMARKS
An acute source of psychological stress, these lesions are present
at birth and usually occur on the face or neck. If untreated, port
wine birthmarks can deepen in color and increase in size and depth
with age. They can become raised, increasing their susceptibility
to abrasion, ulceration, chronic infections and circulatory problems.
Therefore, port wine birthmarks are best treated as early as possible.
There are two phases to laser treatment. The first phase determines
the proper laser energy to clear the lesion. This involves a test
consisting of several laser pulses with differing energy density.
At your next appointment, your physician will evaluate the best
results to determine the proper energy setting for your skin type.
The first of several treatment sessions will then begin.
Use of the pulsed-dye laser causes a discoloration and a bruise
of the skin known as a pupura which lasts for about ten days. However,
it is agreed throughout the medical community that when the pupura
has faded, the pulsed-dye laser offers the most effective treatment
available for port wine stains.
It is important to note that lasers do not always eliminate port
wine birthmarks completely. In about 25% of patients, laser therapy
will completely clear the lesion, while 75% will result in a dramatic
improvement. For reasons that are not well understood, a small number
of patients will not respond to laser treatment.
