We surgically treated 5 patients with the Juxta-dural ring aneurysm. Four patients received clipping of the aneurysm after removal of the anterior clinoid process and opening of the dural ring, and 1 patient received coating of the aneurysm. We treated 2 of 4 patients without specific problems at the time of clipping. However, the clip compressed the optic nerve after aneurysm obliteration in 1 patient. In the other patient, we could not apply a fenestrated clip because the shape of the clip did not fit the curvature of the carotid artery. In this patient, we used an L-shaped clip resulting in unstable placement of the clip. In these 2 patients, it was feared the frontal lobe might press the clip after the operation. To prevent further pressure to the optic nerve and slipping of the clip, we split the cortex just facing the clip in these 2 patients. Recently, the approach to the Juxtadural ring aneurysm has been established. However, clipping remains problematical because of the anatomical limitations surrounding the cavernous sinus
