Abstract
In this paper, we reported two cases of carotid ophthalmic aneurysm. Case 1 had the subchiasmal type of this aneurysm and could be operated on successfully through the interhemispheric approach. Case 2, with bilateral carotid ophthalmic aneurysms, was operated on through a bifrontal craniotomy extenging to the left temporal area. The aneurysm on the left side was treated by wrapping and the one on the right was clipped through a combined contralateral pterional and interhemispheric approach. This combined approach seemed to be particularly useful for some aneurysms on this portion. The surgical approach to carotid ophthalmic aneurysms is discussed.
