Craniotomies for Aneurysms

F our different tailored craniotomies are used for typical anterior circulation aneurysms:

  • pterional craniotomy for internal carotid aneurysms
  • Sylvian craniotomy for middle cerebral aneurysms
  • orbitocraniotomy for anterior communicating artery
  • anterior interhemispheric craniotomy for A2-callosomarginal artery aneurysms


Two approaches are used for posterior circulation aneurysms:

  • lateral paracondylar for vertebral artery aneurysms
  • paramedian for peripheral aneurysms
