색소레이저(Pulsed Dye Laser; SPTL-1) 로 치료한 포도주색 혈관종의 임상효과에 관한 연구

Abstract

Port-wine stains(PWSs) are benign congenital vascular malformation that most commonly occur as isolated lesions on the face, neck, and trunk. The major indication for therapy, regardless of age, is psychological burden imposed by the PWSs. The pulsed dye laser(Candela SPTL-1) is a flashlamp excited dye laser, using the principles of selective photothermolysis that selectively targets the abnormal microvasculatures of cutaneous lesion while sparing adjacent structures including the epidermis, emitting at 585mm wavelength, pulse duration of 450㎲ec and 5mm spot size. From the June 1992 to May 1995, at O.P. D., Department of Dermatology, Keimyung University Hospital, 138 patients with portwine stains were analyzed to evaluate the clinical effects by the pulsed dye laser. The results were as follow : 87.9% of adults and 97.4% of children showed excellent or good results. 86.0% of male and 93.8% of female showed excellent or good results. 90.9% of head and neck, 87.5% 0f trunk, and 87.5% of extremity showed excellent or good results. Complication included transient erythema(12.3%), hyperpigmentation(7.9%), oozing(7.2%), infection(4.3%), edema(2.8%), and hypopigmentation(0.7%). There was no posttreatment sclerosis, hypertrophic or atrophic scar.
