Abstract
Microsurgery of aneurysms that arise in the paraclinoid region remains a formidable challenge to most neurosurgeons. The intricate anatomy related to the internal carotid artery at the site where it leaves the base of the skull to enter the subarachnoid space is responsible for most of the drawbacks of aneurysm surgery in that area.
The planning of the operative strategy requires that one considers some major issues involved with the management of paraclinoid aneurysms, i.e., those related to the anatomical relationships of the paraclinoid area, the characteristics of the aneurysm itself, the choice of the best surgical approach, the site for proximal control of arterial bleeding, and the possibilities for either the improvement or for the arrest of visual deterioration.
