The best treatment for intracranial aneurysm is seemingly direct surgical attack with the neck clipping. The direct neck clipping for carotid-siphon aneurysm, however, is hazardous and difficult as compared with other intracranial aneurysms because of its location adjacent to the skull base, the optic chiasma, and the cavernous sinus. The authors discuss the surgical treatment, especially the approaches to the carotid-siphon aneurysms based on our surgical experiences of 35 cases with 39 such aneurysms.<BR>IC-oph aneurysms projecting superiorly can be treated with neck clipping through the ipsilateral pterional approach. Otherwise, IC-oph aneurysms projecting posteromedially are prefered to clipped through the space between the optic chiasma and the tuberculum sellae via the contralateral pterional approach.<BR>Large aneurysms arising from the carotid-siphon are especially difficult for direct neck clipping except for superiorly projecting IC-oph aneurysms, which can be treated with neck clipping through the pterional approach.
