[Intraoperative Rupture from Cerebral Aneurysm: Tactics for Management and Strategy for Prevention].

Rupture of a cerebral aneurysm during surgery carries risks that may lead to poor patient outcomes. Rupture often occurs during the separation procedure of the aneurysm from the surrounding structure. Knowledge regarding the basic principles of operation of surgical apparatus, for example suction devices, before and after the aneurysm rupture event is of paramount importance. It is desirable to deal with these complicated situations automatically in a non-heuristic manner, although some experience and learning are necessary to obtain this ability. When we necessarily apply temporary occlusion of the parent arteries, we need to consider the merits and demerits of temporary occlusion, as well as the limits of the occlusion time in order to prevent ischemic complications.
