ORIGINAL
The authors reviewed the technical details of microsurgical clipping of non ruptured anterior communicating artery aneurysms. Details of the dissection are emphasized as well as the main indications. Discussion of anatomical aspects and landmarks were developed and the endovascular treatment was also concerned in this overview. The microsurgery of brain anterior communicating 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.
