The endovascular management of cerebral aneurysms is undergoing revolutionary growth. Recent advances in endovascular surgery including balloon remodeling, revascularization techniques, functional cerebral rearrangement, intracranial stents, treatment for vasospasm and coil design are discussed, as are their future considerations.

Middle cerebral artery (MCA) aneurysms account for approximately 20% of aneurysmal subarachnoid hemorrhage (SAH). An understanding of MCA anatomy and variations is the key to successful treatment of MCA aneurysms, which may occur on the M1 segment, at the division of the main trunk or on distal branches. ⋯ MCA aneurysms associated with large temporal hematomas may be approached through the superior temporal gyrus. Other aneurysms are best approached with a medial or lateral transSylvian approach.
