Evaluation of the effectiveness of laser treatment capillary malformation in children (systematic review)

Abstract

Background. Capillary angiodysplasia is a common vascular malformation represented by an increase in the number of dilated capillaries of the skin. Being located in the face area, this defect contributes to the development of an inferiority complex in a child. Various methods are used for treatment, but all of them are not effective enough. Currently, the most effective and promising method is laser photodestruction.Aim. To study the efficacy and safety of laser treatment of skin сapillary angiodysplasia in children with various laser devices (PDL 585 nm, Nd:YAG 1064 nm, Nd:YAG/KTP 532 nm), based on a systematic review of modern literature for the period from 2000 to 2020.Materials and methods. A systematic review was conducted in foreign and Russian databases for the period from 2000 to 2020. Keywords were used for the search: capillary angiodysplasia, capillary malformation, wine stain, vascular malformation, laser treatment. Out of 1543 literature sources, 9 full-text articles are included in the review.Results. Comparing the results of treatment using different types of lasers, it was noted that a very good result was achieved in 33.8% of cases, good in 33.7%, average in 20.4%, no effect in 1.2%. The total number of complications was 62 cases (9.5%): hyperpigmentation in 32 patients, scars in 15 cases, hypopigmentation in 12, skin atrophy in three.Discussion. The conducted systematic review indicates the effectiveness and disadvantages of using various laser radiation for the treatment of capillary angiodysplasia of the skin. The articles lack information on the relationship between the effectiveness of treatment from morphological and hemodynamic features of vascular formations and the selectivity of laser radiation to skin chromophores.Conclusion. It is necessary to conduct research to select the optimal laser radiation, taking into account the morphological and hemodynamic features of capillary angiodysplasia, which will ensure minimal skin damage and improve treatment results.
