Considerations in early surgery on good-risk patients with ruptured intracranial aneurysms

A retrospective analysis of 100 consecutive patients with proven ruptured intracranial aneurysms, classified as Botterell Grades I to III on admission, was carried out to evaluate the efficacy of early operation. Surgical and management mortality/morbidity rates were lower for cases in which a single hemorrhage was operated on within 48 hours than when surgery was delayed for 7 days or more. Surgical and management mortality/morbidity rates were worse in good-risk patients treated surgically between the 3rd and 7th days following a hemorrhage, reflecting the increased incidence of postoperative vasospasm and raised intracranial pressure encountered at surgery during this interval.
