title: Contralateral approach to carotid cave aneurysms.
abstract: BACKGROUND
  To evaluate the surgical approach and clipping of aneurysms located at the carotid cave region.
  
  
  METHODS
  Between 1980 and 1998 we have adopted the well known ipsilateral approach for exposure and securing of carotid cave aneurysms. In four patients, we had the opportunity to use a contralateral approach to carotid cave aneurysms, with easier dissection and application of a simple aneurysmal clip. The visual acuity of the patients did not deteriorate from the pre-operative level.
  
  
  RESULTS
  Aneurysms located at the carotid cave region may be approached easily and safely through a contralateral craniotomy with application of the aneurysm clip from an angle medial and inferior to the optic nerve.
