Resumo
O conhecimento da vascularização é essencial para o planejamento cirúrgico e a realização de procedimentos intervencionistas na região axilar. A artéria axilar origina ramos que suprem o ombro, a parede torácica e a escápula, continuando-se então como artéria braquial, que fornece ramos para o braço e o cotovelo. Pequenas variações nesses ramos são comuns. No entanto, a dissecção de um membro superior direito fixado em formol revelou uma artéria axilar que se bifurcava em uma artéria braquial superficial, sem ramos, e em um tronco posterior, responsável por todos os ramos que tipicamente se originam da terceira porção da artéria axilar e da artéria braquial, incluindo a artéria subescapular, as artérias circunflexas umerais, a artéria braquial profunda e as artérias colaterais ulnares. Esse arranjo vascular raro não havia sido descrito anteriormente na literatura brasileira. O conhecimento dessas variações pode prevenir erros diagnósticos e lesões durante cirurgias.
