Multiple intracranial aneurysms
Abstract
Patients with multiple intracranial aneurysms carry an additional risk of poor outcome due to presence of other aneurysms and the complexity of treatment. Patient’s age is crucial in decision making because of its major effect on outcome and mortality. Objectives: The purpose of this study was to assess incidence and outcome in multiple aneurysmal SAH in a series of 357 consecutive patients. Material and method: We retrospectively analyzed a series of 366 patients with ruptured aneurysms treated between Jan 2006 and Dec 2009 in our department. We study the incidence, localization, surgical outcome and treatment method for individualized patients. We analyzed short-term outcome of multiple aneurysm in comparison to the single in accordance to Glasgow Outcome Scale at discharge. Data of all patients with aneurysmal SAH treated between 2006 an 2009 in our department were collected from their chart; operative notes and used to evaluate the incidence and outcome for three patient’s age category. Results: For both single and multiple aneurysms the incidence was significantly higher in women than in men. Outcome differ statistically between patients with multiple and single aneurysms in age groups 40-69 and 70-89 years. Conclusions: The incidence of multiple intracranial aneurysms is higher in women than in men, the site of rupture are different between the two groups in male the site of rupture is dominated by the anterior communicating artery aneurysms while in women it is represented by the internal carotid artery aneurysms. Patients with multiple intracranial aneurysms had a higher mortality than patients harboring single intracranial aneurysms.
