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.

ReviewTemporary vascular occlusion during cerebral aneurysm surgery.
Temporary artery occlusion is an effective way to reduce the detrimental effects of intraoperative aneurysm rupture and to facilitate aneurysm dissection. The major risk incurred is of cerebral infarction. Dilemmas in the use of this technique include the amount of time that arterial flow may be interrupted safely and whether or not there is benefit to intermittent reperfusion. Protocol for the use of temporary occlusion is described.
