Para- and infraclinoidal aneurysms. Anatomy, surgical technique and report on 22 cases

The internal carotid artery in its intracavernous portion is covered by a soft connective tissue layer. At the entrance of the artery into the subarachnoid space there is a very dense fibrous ring fixing the artery wall at the roof of the cavernous sinus. After cutting the fibrous ring it is possible to dissect along the artery wall without opening the cavernous sinus. The anatomical details are described.
