“…It is also recommended to use laser therapy for additional 8-18 months to manage persistent lesions. It significantly improves the size and colour of such lesions (10) . The Nd-YAG laser, which ensures complete resolution of superficial lesions and shows high efficacy in the case of complex and deep haemangiomas in the growth phase, is an alternative for dye lasers.…”

Advances in laser techniques used in medicine significantly expanded the pool of procedures as well as increased the frequency and ease of their use. Paediatric surgery is one of the branches of medicine open to use the dynamically developing laser technologies. Based on the current literature and our own experiences, we present a cross-sectional review of modern applications of laser therapy in the paediatric population. Laser therapy is often used complementary to other treatment methods and, in many cases, it becomes the main treatment approach in a variety of conditions. It is an indispensable element in the management of many diseases, both those health-and life-threatening as well as those responsible for cosmetic defects directly contributing to reduced quality of life of patients. This allows for a very short recovery time, with a low risk of adverse effects. The method is gaining popularity and is continuously improved. It is used, among other things, in the management of congenital and acquired vascular lesions, pilonidal sinuses, and scars. Undoubtedly, the future use of laser therapy in paediatric surgery will definitely expand to include further disease entities. A brief overview of therapeutic options for conditions in which laser therapy has become the leading therapeutic strategy can help general practitioners and paediatricians choose the optimal treatment strategy for their patients. Raising the awareness of general practitioners of indications for laser therapy may bring significant benefits for paediatric patients. Laser is becoming an increasingly available tool, which, considering the efficacy of laser therapy and a large number of indications, encourages referring patients to specialists performing such procedures.

O hemangioma infantil é o tumor vascular benigno mais frequente na idade pediátrica, com uma incidência de 2% a 12% em recém-nascidos caucasianos, com predominância no sexo feminino. A International Society for The Study of Vascular Anomalies dividiu as anomalias vasculares em duas categorias: tumores vasculares e malformações vasculares, integrando-se o hemangioma infantil nos tumores vasculares benignos. A evolução clínica é característica, compreendendo uma fase proliferativa e uma fase de involução. O diagnóstico é habitualmente clínico, mas pode haver necessidade de recorrer a métodos auxiliares de diagnóstico. A maioria dos hemangiomas infantis tem evolução favorável no sentido da resolução espontânea, mas nalguns casos pode haver complicações locais ou sistémicas, com necessidade de intervenção terapêutica por situações de risco vital, funcional ou estético. Atualmente, o propranolol oral é o tratamento de escolha para o hemangioma infantil e o único aprovado para esta indicação, devendo ser administrado o mais precocemente possível para uma maior eficácia e um menor número de complicações. Outras opções terapêuticas podem ser equacionadas em segunda linha: corticoides orais, tópicos ou intralesionais, betabloqueantes tópicos, laser ou cirurgia.

“…Compared with the other laser wavelengths, the 940-nm semiconductor laser exhibits less absorption of melanin so is more suitable for dark skin and deeper blood vessel lesions with a diameter of more than 0.3 mm. 6 At present, the majority of high-power laser therapeutic instruments used in clinical applications are single wavelength; therefore, they cannot fully meet the requirements for clinical treatment. 7 For example, Dornier Medilas D series for varicose veins, 1470-nm semiconductor laser therapeutic instrument of Biolitec company in Germany for prostate treatment, etc.…”

The majority of existing high-power laser therapeutic instruments employ a single wavelength for a single target; thus, they do not meet the requirements for clinical treatment. Therefore, this study designs an optical system for a dual-wavelength high-power laser therapeutic device with a variable spot size. The waist of the short arm of the optical cavity and the G1G2 parameter (G-parameter equivalent cavity method) is calculated using MATLAB software, the spot size and divergence angle on the lens are calculated using an ABCD matrix, and the distance between the treatment spot at different spot sizes and the transformation lens is calculated in order to design the treatment handpiece. Experiments are conducted to analyze the stability at an output power of 532 nm before beam combination and the power loss after beam combination. The results show that the output power stability of the 532-nm beam varies by less than 2% over 150 min, and the loss of both wavelengths is less than 20%, which meets the clinical requirements of the system. The safety performance can meet the requirements of national general standards for medical electrical safety. The proposed dual-wavelength laser therapy instrument has both visible wave and near-infrared wave characteristics; thus, it can accurately target both superficial vessels and vessels with a larger diameter and deeper position. This therapeutic device has the advantages of simple operation, stable and reliable laser output, high security and strong anti-interference ability, and meets the comprehensive clinical treatment demands of vascular diseases.
