Os autores revisaram os detalhes técnicos da clipagem microcirúrgica de aneurismas cerebrais médios não rotos. Os detalhes da dissecção são enfatizados, bem como as principais indicações. A discussão dos aspectos anatômicos foi desenvolvida e o tratamento endovascular também foi abordado nesta visão geral. A microcirurgia de aneurismas cerebrais continua sendo um desafio e todos os esforços para manter o conhecimento e os conceitos da abordagem microcirúrgica devem ser preservados, sendo este o objetivo principal deste artigo.
The authors reviewed the technical details of microsurgical clipping of non ruptured middle cerebral aneurysms. Details of the dissection are emphasized as well as the main indications. Discussion of anatomical aspects and landmarks was developed and the endovascular treatment was also concerned in this overview. The microsurgery of brain aneurysms remains a challenge and all efforts to keep the knowledge and concepts of microsurgical approach ought to be preserved, being the main goal of this article.
