<title>Pulsed-laser therapy (GA-As) in combined treatment of post-traumatic swellings and some dermatological disorders</title>

Abstract

The effect of a pulsed gallium arsenide infrared laser radiation was studied on 64 patients with post traumatic swellings, allergic vasculitis and varicose crural ulcers, therapy resistant. The soft laser therapy was conducted in combination with classical therapy and was compared with a non irradiated control group of 52 patients treated only by classical therapy. Laser irradiation was directed to the skin damage by laser scanning. Segmental and dermatomic areas of the skin lesions were irradiated by laserpuncture. Therapeutic protocol included an average of nine sessions. The statistical analysis shows a significant difference of the efficiency between Ga-As pulsed laser treated group and the control group, especially in the case of post-traumatic swellings and less in the case of allergic vasculitis. The effects reported by this study are relevant for clinical application of infrared pulsed low lasers in dermatology.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.
