The advances of the endovascular techniques observed in the past two decades has made this surgical alternative, previously recommended only for aneurysms with no indication to be treated by conventional surgical technique (clipping), into a first choice approach for a large number of cerebral aneurysms in some services [1][2][3] . One of the main advances in these techniques was the advent of detachable platinum coils termed Guglielmi detachable coils (GDC). The development of coils with a better capacity to conform to aneurysms, quicker and safer detachable mechanisms and the use of bioactive materials in addition to coils are responsible for the higher rate currently obtained in aneurysm occlusion 4 . GOS 2 e 11,5% GOS 1. Conclusão: A aplicação de técnica endovasculares mostra-se viável na rede públi-ca brasileira, com resultados comparáveis aos de grandes centros mundiais.PAlAVRAS-CHAVE: aneurisma intracraniano, tratamento endovascular, coil.
