Intracranial aneurysms larger than 25mm in diameter are considered giant
aneurysms and these comprise about 5% of all
intracranial aneurysms. The authors
report a series of 9 cases of giant
cerebral aneurysms(>2.5cm in diameter) during a 7-year-period found among 212 cases with saccular
cerebral aneurysms. Of the 9
patients, four
patients were treated by direct
neck clipping, one by
trapping, and the other one by sac excision after direct
neck clipping. This
report presents an
analysis of 9 cases of giant
cerebral aneurysms. The results are as following 1) In a
review of our cases of giant
aneurysms, approximately 4.3% were of all
intracranial aneurysms. 2)
Male Female ratio was 4 5. 3) The greatest
incidence was in the 6th decade of
life. 4) The most common site was in the
internal carotid artery portion. 5) Our all cases were saccular
aneurysms. 6) In our cases, nonthrombosed
aneurysms were more common. 7) Presenting symptom of SAH was more common. 8) There was no relationship between
blood pressure and
aneurysm rupture in our cases. 9) We found our all cases of ICA portion giant
aneurysms presented with focal symptoms. 10) The most commonly presented focal
neurologic sign was visual failure.
