SCIENTIFIC PAPER – ABSTRACT Malformações capilares: resultados preliminares do tratamento associando laser ND:Yag 1064 nm e luz intensa pulsada Motta M.M., Kharmandayan P., Danielli Nicola E.M., Nunes P.H., Psillakis J.M., Revista Brasileira Cirugia Plastica (RBCP) (2010). Introdução: As malformações vasculares congênitas do tipo capilar têm seus melhores resultados até o momento com o laser de corante. Nós associamos, em um único equipamento, o laser ND:Yag 1064 nm de pulso longo e a luz intensa pulsada, para o tratamento de lesões superficiais e profundas. Método: Dezessete pacientes foram tratados com a associação descrita em regime ambulatorial, com anestesia tópica apenas em intervalos mensais, pelo mesmo cirurgião. O equipamento utilizado foi a plataforma Synchro (DEKA), com a ponteira de 4 mm de diâmetro e fluência de 110 J/cm2 para o laser ND:Yag 1064 nm. Para a luz intensa pulsada foi utilizado um filtro de corte de 550 nm, a ponteira de 46 x 10 mm e 21 J/cm2 de fluência, divididos em dois disparos. Os resultados foram avaliados clinicamente e por meio de fotografias, em conjunto com os pacientes. Resultados: Dentre os dezessete pacientes tratados, quatro resultados foram considerados excelentes, nove, bons, quatro, regulares e nenhum insuficiente. Conclusão: O tratamento pode ser realizado adequadamente com anestesia tópica em regime ambulatorial. A associação das duas tecnologias possibilitou a obtenção de resultados satisfatórios e provavelmente é mais uma técnica no tratamento destas lesões. *
Versatility of the Nd‐YAG laser in the treatment of facial vascular alterations Goldman A., Rossato F.,Wollina U., ‐ Kosmetische Medizin (KM) (2008) Treatment of vascular alterations on the face represented a real challenge before the current use and concept of laser therapy. In the past years, several types of laser have been used in the treatment of these very frequent cutaneous vascular lesions. Among such lesions, telangiectasias and small veins of the face have stood out due to their incidence, frequency and aesthetical repercussion. A long‐pulsed Nd‐YAG laser at 1064 nm (neodymium:yttrium‐aluminium‐garnet) has been proven efficient in the treatment of such conditions. This study shows the clinical effects and safety of applications with the Nd‐YAG laser system when treating some vascular alterations on the face. * 1
Stretch Marks: Treatment Using the 1,064‐nm Nd:YAG Laser Goldman A., Rossato F., Prati C. – Dermatologic Surgey (DS) (2008) Background. Striae are frequent skin lesions that cause considerable aesthetic concern. The 1,064‐nm long‐
pulsed Nd:YAG laser has been used to promote an increase in dermal collagen and is known to be a laser that has a high affinity for vascular chromophores. Objective. This study aims to verify the efficacy of the long‐pulsed Nd:YAG laser in the treatment of immature striae. Materials and Methods. Twenty patients who had immature striae, i.e., red striae, were treated using the 1,064‐nm long‐pulsed Nd:YAG laser. The analysis of treatment efficacy was performed by the comparison between the images taken before and after each treatment session as well as through a subjective assessment carried out by the patients themselves. Result. Results were considered satisfactory to both patients and doctors. A higher number of patients (55%) considered the results excellent when compared to the same assessment made by the doctor (40%). Conclusion. The clinical improvement of immature striae can be obtained with the use of the 1,064‐nm long‐pulsed Nd:YAG laser. The low incidence of side effects makes this laser a good alternative in the treatment of these common skin lesions.
* Nd:YAG 1064 nm laser in the treatment of facial and leg telangiectasias A Major A., Brazzini B., Campolmi P.,Bonan P.,Mavilia L.,Ghersetich I., Hercogova J., Lotti T. – Journal European Academy of Dermatology and Venereology (2001). Background. Facial and leg telangiectasias are a frequent cosmetic concern for both females and males with various skin types and ages. To date the different treatments for these problems, in particular leg telangiectasias, have frequently failed or led to negative side‐effects. Objective. This study examines the clinical effects and safety of applications with a 1064‐nm Nd:YAG laser system (SmartEpil II, DEKA M.e.l.a., Florence, Italy) to treat vessels on the face and legs. Materials and methods. Twenty‐five subjects with facial telangiectasias underwent one treatment at 100 J/cm2, 10 ms and 2 Hz repetition rate. Thirty‐two subjects with leg telangiectasias, measuring 0.1–3 mm in diameter, were treated at 125–200 J /cm2, 10–30 ms and 2 Hz repetition rate. Subjects in this group underwent one to five treatment sessions at 8 week intervals. Results. All subjects showed visible improvement, with 95–100% clearing of the face telangiectasias after only one treatment, and 50–100% clearing of the lower extremity vessels after three to five treatments. Transitory hypopigmentation was seen in two cases subjected to leg vessel treatment. Conclusions. Treatment of facial and leg telangectasias using a true long pulse 1064 nm Nd:YAG laser is an effective and safe method. The relative lack of discomfort combined with a high degree of individual satisfaction should play a part in the fairly high level of acceptance of this new form of therapy for the treatment of leg and face telangiectasias. 2
