Surgical management of cerebral aneurysms in comparison with endovascular treatment.

SUMMARY: We report our surgical results of 92 intrabasal (below the ophthalmic segment) carotid aneurysms and 16 basilar aneurysms after the era of skull base surgery. These lesions were the most difficult location for neck clipping of aneurysms. Mortality, surgery associated mortality and morbidity of intra basal carotid aneurysm surgery were 2.2%, 0% and 9.7% respectively. Mortality and morbidity of basilar ameurysm surgery were 0% and 6.2% respectively. Although endovascular treatment of cerebral aneurysms with detachable coils is premising treatment due to its convenience and less invasiveness, results of this treatment must be superior to the results of microsurgery for it to become a widely accepted therapy.
