Extadural-Intradural Approach to Carotid-Ophthalmic Artery Aneurysm

Abstract
|
|
|
The authors report seven cases of carotid-ophthalmic artery aneurysms who were surgically treated using the combined extradural-intradural or intradural approach from March, 1991, to December, 1993.
Carotid-ophthalmic artery aneurysms are of considerably surgical interest because some of these were considered to have technical difficulties of clipping and disastrous surgical results. Removal of the anterior clinoid process and unroofing of
the
optic canal are the key points to exposure the operative field adequately.
On the basis of these experiences, authors concluded that this approach is very useful, bacause of adequate surgical field and better mobilization of the internal carotid artery and optic nerve for direct clipping of carotid-ophthamic artery
aneurysm
and basilar tip aneurysm.
