Resumo
Objetivo: Relatar o caso de um paciente pediátrico que fez uso do sirolimo, um inibidor mTOR, para o tratamento de malformação vascular de fluxo lento, avaliando a segurança e eficácia da medicação. Detalhamento do caso: Criança, 3 anos de idade, acompanhado no ambulatório de Dermatologia do Hospital Universitário Lauro Wanderley, com diagnóstico de linfangioma, refratário aos tratamentos com propranolol via oral e infiltração de bleomicina. Após início do tratamento com sirolimo oral e realização de cirurgia, com exérese parcial da lesão, houve redução da lesão em cerca de 64% em relação ao tamanho inicial, com melhora significativa da qualidade de vida. O paciente mantém acompanhamento no ambulatório, com programação de uso do sirolimo por 1 ano e 9 meses. Considerações finais: As opções terapêuticas para as malformações vasculares são limitadas. O sirolimo tem se mostrado um tratamento promissor, principalmente para as formas clínicas mais graves. A pequena amostra e a ausência de padronização da dose foram as principais limitações do estudo.
