LASER SURGERY FOR CUTANEOUS SIMPLE CAPILLARY MALFORMATIONS IN CHILDREN

Abstract

There are presented data on the epidemiology, pathogenesis, and diagnosis of cutaneous simple capillary malformations, described as Nevus simplex and Nevus flammeus (NF) in the Classification of Vascular Anomalies in a revision on May 2108. There are compared the efficacy and side effects of an application of laser irradiation of different wavelengths for the laser surgical treatment of NF in patients of various ages. There are described features of morphometry and angioarchitecture of the vascular bed of NF at the early and advanced stages of the disease. In order to substantiate the choice of the preferred laser irradiation settings, the peculiarities of absorption of the laser irradiation with different wavelengths by main cutaneous photothermophores (chromophores) are compared in children of various ages. For the first time, there are presented data on the age-related features of the absorption coefficient and the relevant absorption index for laser irradiation of different wavelengths. The maximum values of the absorption coefficients and the index of the relevance of the absorption of laser radiation with a wavelength of 578 nm by the main skin photothermophores indicate the greatest efficiency of the domestic copper vapor laser for the surgical treatment of NF in children of different ages.
