Laser Results of Leg Veins
Posted: Monday. September 8, 2008
The development of lasers using deeper-penetrating, near-infrared wavelengths with millisecond pulse durations and skin-cooling methods has produced safer and more predictable results for the results of leg veins less than 1 mm in diameter and depth. Recent prospective studies of the near-infrared lasers show comparable efficacy and side effect profiles to those observed with sclero .
Results of reticular and varicose veins is effective with these wavelengths but is limited by patient discomfort when compared with sclero . Visible light lasers (such as the pulsed dye and KTP) and intense pulsed-light sources are reproducibly effective only for superficial, nonarborizing pink-to-red telangiectasia, in the absence of points of proximal reflux. Because most lower-extremity vascular ectasias comprise a heterogeneous group of vessel sizes and depths, many patients achieve the best results using a combination of techniques. This article reviews the fundamentals of laser tissue interactions for the results of leg veins and details the recent clinical experience with the newer near-infrared devices.
