ABSTRACT

The introduction of the operating microscope improved not only the immediate operative management of cerebral aneurysms, but also the knowledge of their topography. The origin and projection of an aneurysm and its relation to the arteries concerned, identification and sparing of small functionally important arteries in the vicinity of the aneurysm, and the recognition of less known anomalies of the vascular system became as important as the dissection and clipping of the neck itself. We have presented 2 patients with aneurysms arising from the carotid artery in the origin of the ophthalmic artery. The origins and projections of aneurysms were analyzed with the aid of angiography, magnification technique, operative drawing and photographs. To facilitate the surgical procedures and results in lowered morbidity we have discussed the technical considerations for medialward directing aneurysm under the optic nerve in the view point of the surgical anatomy. We emphasized preoperatively defined plans concerning the origin, direction and size of the aneurysms, as well as, constant awareness of topographic relations.
