Resultados de médio e longo prazo do tratamento endovenoso de varizes com laser de diodo em 1940 nm: análise crítica e considerações técnicas

Abstract: Resumo Contexto Desde a introdução do laser endovenoso para tratamento das varizes, há uma busca pelo comprimento de onda ideal, capaz de produzir o maior dano seletivo possível com maior segurança e menor incidência de efeitos adversos. Objetivos Avaliar os resultados de médio e longo prazo do laser de diodo de 1940 nm no tratamento de varizes, correlacionando os parâmetros utilizados com a durabilidade do desfecho anatômico. Métodos Revisão retrospectiva de pacientes diagnosticados com insuficiência venosa c… Show more

“…According to previous literatures, the required energy for good outcomes is about 80-100 LEED (J/cm) with the 1,470nm EVLA (11,13,14). And to date, a few studies have investigated EVLA using the 1,940-nm laser, and this treatment has generally produced good outcomes, even with energy < 50 LEED (J/cm) (19)(20)(21)(22)(23)(24).…”

“…A variety of wavelengths are used to perform EVLT (810, 940, 980, 1,320, 1,470, and 1,940 nm). 21 The different types of laser fiber administer energy to the vessel in different ways. Examples include conventional, tulip, nevertouch TM , and radial fibers.…”

“…As grandes questões relacionadas com o uso do laser são definição do melhor tipo de fibra, qual o comprimento de onda mais adequado a ser utilizado e conhecimento da LEED ideal a ser aplicada em cada área. Existe uma variedade de comprimentos de onda que são utilizados para a realização do EVLT (810, 940, 980, 1.320, 1.470 e 1.940 nm) 21 . Ao mesmo tempo, os diferentes tipos de fibra do laser possibilitam que a energia seja aplicada no vaso de maneiras distintas.…”

“…Therefore, during the ablation process, it is necessary to administrate energy capable of generating elevated temperatures to effectively close the venous segment being treated. 12,13 Some factors that may have influenced our high occlusion rate were: all patients were subjected to tumescence of the vein to be treated; all were in the Trendelenburg position; and a 600 micron radial fiber was used. The larger the diameter of the fiber, the higher the final temperature reached and the better the distribution and conduction of heat to the wall of the vein.…”
