title: Internal carotid artery rotation technique to expose an aneurysm neck: technical note.
abstract: OBJECTIVE
  Full exposure of a neck of an aneurysm is important to obliterate it completely.
  
  
  METHODS
  A 51-year-old woman in whom an unruptured aneurysm projecting medially under the optic nerve was incidentally found underwent clipping surgery. The edge of the circumferentially cut distal dural ring was pulled with forceps to rotate the internal carotid artery and to expose the neck of the aneurysm.
  
  
  RESULTS
  The neck of the aneurysm was completely obliterated under direct vision.
  
  
  CONCLUSIONS
  This single, neat method exposes the neck of an unruptured paraclinoid aneurysm of the internal carotid artery.
