“…In the field of dermatology, variable-pulse 595 nm PDL is now being widely used to treat vascular skin lesions, [6–9] and has been successfully used to treat SN. However, several treatment sessions are needed because of its high flow, [3] and there are few reports on the efficacy of different operational methods of 595-nm PDL in the treatment of SN.…”

Background:Spider nevi (SN) are quite common in children. SN are treated via different techniques, and complete removal often requires multiple treatments. However, few studies have evaluated the treatment of SN. The present study aimed to evaluate the therapeutic effect and safety of a 595-nm pulsed-dye laser (PDL) for treating facial SN in children.Methods:A total of 110 children aged 0.2 to 12 years with facial SN were treated with a 595-nm PDL in a single institution from January 2016 to February 2018. In accordance with the treatment method, the patients were retrospectively divided into the small-spot-combined-with-large-spot group (SL-group) and the large-spot group (L-group). Patients with poor therapeutic results were re-treated every 6 weeks until the lesions disappeared. The minimum follow-up period was 1 year. The groups were compared using independent-samples t tests, Mann-Whitney U test, Chi-square test, and Fisher exact probability test.Results:The therapeutic efficacy was significantly higher in the SL-group than in the L-group, with clearance rates of 90.9% and 53.0% after the primary treatment, respectively (χ2 = 17.937, P < 0.001). For skin lesions with a central spider body diameter ≥1 mm, the once-treatment cure rates were 100% in the SL-group and 34.8% in the L-group (χ2 = 20.780, P < 0.001). For skin lesions with a central spider body diameter <1 mm, the once-treatment cure rates were 82.6% in the SL-group and 62.8% in the L-group (χ2 = 3.961, P = 0.138). The rates of adverse reactions and recurrence did not differ between the two groups (P = 0.141 and P = 1.000, respectively).Conclusions:The 595-nm PDL might be a safe and effective treatment option for facial SN in children. The small-spot-combined-with-large-spot method is especially suitable for SN with a central spider body diameter ≥1 mm.

“…Absorpcja światła laserowego podgrzewa chromofor, co prowadzi do uszkodzenia ścian naczynia [4,7]. Do niedawna standardem leczenia naczyniowych zmian skórnych był laser PDL 595 nm z uwagi na dobrą penetrację do skóry właściwej, niemniej z uwagi na wysoki koszt leczenia i ryzyko plamicy i pęknięcia naczyn, w przypadku zmian powierzchownych, badacze zaczęli poszukiwać alternatywnych rozwiązan [10]. Atrakcyjnym przedmiotem badan stał się laser KTP z falą o długości 532 nm, która znajduje się w pobliżu jednego z pików absorpcyjnych oksyhemoglobiny.…”

“…Badacze z Korei w swoim badaniu wskazują, iż większość leczonych pacjentów z użyciem laseroterapii doświadczyła przejściowego bólu i rumienia bezpośrednio po zabiegu laserowym, który ustępował w ciągu 30 minut. Najczęstszymi działaniami niepożądanymi lasera KTP jest miejscowe zaczerwienienie i obrzęk [10].…”

The use of the KTP 532 nm vascular laser in the treatment of erythema and telangiectasia caused by low temperature exposure - case report. A case report. The paper presents a case of effective treatment of frostbite vascular lesions in the face with the use of a 532nm KTP laser in a 55-year-old man with a long history of skin exposure to low temperatures. Aim. The aim of this study is to draw attention to the possibility of using laser therapy in the treatment of skin disorders that are a complication of exposure to low temperatures. In the article below, we present the reduction of vascular lesions of the facial skin during a series of laser treatments with the use of the 532nm laser, meeting the growing interest of patients and doctors in the use of laser therapy in the treatment of skin vascular lesions. Conclusions. The use of laser therapy with the KTP 532nm laser can be an important and effective element in the treatment of skin vascular lesions.
