Patient selection: rupture of an intracranial aneurysm
Patient factor associated with a worse outcome:
(1) male gender
(2) history of hypertension
(3) older age (> 50 years)
(4) history of alcohol misuse
(5) smoking
Features of the aneurysm and rupture associated with a worse outcome:
(1) aneurysm >= 10 mm in diameter
(2) aneurysm in the posterior circulation (vertebrobasilar)
(3) intraoperative rupture of the aneurysm
(4) patient status after the rupture either low Glasgow Coma Score (GCS) or Hunt and Hess Grade III or higher
where:
• Some of these factors are not independent. For example, the Hunt and Hess grade was influenced by aneurysm size and location.
A final conclusion was that prompt diagnosis and management of patients with favorable factors was associated with a good neurological outcome following aneurysmal rupture.
