Note.—α indicates patients in whom ophthalmic artery was covered with the stent graft; M, male; F, female; R, right; L, left; cav, cavernous internal carotid artery; petrocav, petrous and cavernous portion of the internal carotid artery; caroticooph, carotico-ophthalmic segment of the internal carotid artery; 6n, sixth nerve; 3n, third nerve; 2n, second nerve; SAH, subarachnoid hemorrhage; β, patients who had nasal bleeding; NA, not applicable because the time interval since treatment was <6 months and no control angiography had yet been performed.
* Control Angiography, latest angiography performed; Mass Effect Early Outcome, evaluation of mass effect symptom at end of second week; Mass Effect Late Outcome, evaluation during clinical follow-up (during third month unless otherwise indicated).
† Aneurysms were partially thrombosed.
