Argon Laser Therapy of Nevus Flammeus
Abstract
- Nevus flammeus is benign but cosmetically devastating congenital vascular malformation whose past treatments have been marred by unacceptable complication or by unacceptable ineffectiveness. The argon laser is a therapeutic device which has been newly applied to this condition. Blue-green argon light is absorbed by the intraluminal red hemoglobin molecule, leading to the destruction of blood vessels. This study was undertaken to evaluate the therapeutic effect, to look for complications caused by the argon laser on nevus flammeus and to investigate the prognostic values of the color, the degree of blanching and the histological pattern of lesion after laser treatment. All patients were treated with Coherent Radiation Model No. 1,000 Laser with a spot size of 1mm diameter. The power range was 1.8W (irradiance of 229W/cm2), the pulse duration was 0.4 second and the repetition rate was 120 impulses per minute. The result was evaluated according to the criteria of Gilchrest(Table 1). Among the 109 patients who have been treated between November, 1981 and July, 1982 at the Department of Dermatology, Seoul National University Hospital, data from the 49 patients who could be followed up was evaluated and analyzed.
