KDL-102型色素レーザー治療装置の使用経験

抄録

Since early 1980's, an excellent effect of the dye laser treatment for portwine stain and other superficial hemangiomatous lesions has been aware of and, nowadays, it has been a main method for the treatment for these lesions.
We have had a chance to use the Japan Laser Systems' model KDL-102 dye laser system for the treatment of thirty cases of portwine stain and other lesions. These were twenty eight cases of portwine stain. Thirteen cases of them were superficial located type and fifteen cases of them were fully located type. The other two cases were telangiectasia and angiokeratoma.
Evaluation was made at the time of two or three months after one dye laser treatment and based on the degree of blanching and scar formation as side effect of the treatment. The degree of blanching was divided into three steps: Excellent means remarkable blanching: Good means still existing reddish coloring of the skin; and Poor means almost no change in the portwine stain.
The evaluation of blanching was that one superficially located portwine stain resulted in Excellent, twenty six cases of which ten cases of superficially located portwine stain, fourteen cases of fully located portwine stain, telangiectasia and angiokeratoma., resulted in Good, three cases of which two cases of superficially located portwine stain and one case of fully located portwine stain resulted in Poor. Post operative scar formation as side effect occurred in two cases, telangiectasia and fully located portwine stain, but both were not serious.
This result was almost as same as the result of another system that has been used in our unit now.
