Middle cerebral artery aneurysms: challenges for microsurgical approach

The authors present their series about middle cerebral artery (MCA) aneurysms. They discuss anatomical aspects as well as the results and complications of surgical treatment. Besides, they defend the idea that for having good results, it is necessary an extent Sylvian´s cistern dissection, permitting an adequate exposure of the aneurysms and their relationships not only with the MCA but with its branches, emphasizing too the not usefulness of temporary clipping in the approach of this pathology.
