Answer

Microsurgical techniques focus on excluding the aneurysm from the cerebral circulation and reducing mass effects on adjacent structures. Various approaches have been developed and tailored to the anatomy and location of the aneurysm. A surgical clip usually is placed across the aneurysm neck with preservation of the parent vessel, eliminating any aneurysmal rests that may redevelop subsequently. Alternative techniques involve proximal or Hunterian ligation, wrapping the aneurysm, and trapping (ie, combined proximal and distal vessel occlusion).
