Adjunctive measures have been developed to reduce operative morbidity and to provide cerebral protection. Aneurysmal rupture, the principal surgical complication, may be avoided with induced hypotension, CSF drainage, diuretics, hyperventilation, and use of minimal brain retraction. Hypothermia, with or without circulatory arrest, and systemic hypotension are used commonly. A large study of mild intraoperative hypothermia, however, failed to demonstrate benefit of this adjunctive technique.
