抄録

Dye laser therapy is appeared to be the first choice for the treatment of port wine stain. However it is safe to say that many patients with port wine stain are used to recieved several times of this therapy until they were satisfied with their results. On the other hand, the effect of dye laser therapy on the leasions of extremities is not reliable yet. This paper would report about a new approach to improve those results following the dye laser therapy.
What we name the negative pressure method is that a laser ray is shot at the spot which is conditioned with the negative pressure (300 torr under the atmosphere pressure). The status of dye laser rays are as follows: 1. Wavelength is 575nm. 2.Pulse duration is 300msec. 3.Laser ray energy is 6.0J/cm2 4. Spot size is 5mm in diameter.
Our new method provided appearently better results in comparison with those of conventional method. Those will be reported in detail and also their histological findings will be discussed.
