75-year-old-woman with SAH.
A, Anteroposterior right carotid angiogram shows a broad-based aneurysm at the termination of the internal carotid artery.
B, Digital radiograph shows failed attempt to treat the aneurysm with conventional coiling owing to bulging of the coil into the parent artery.
C, Digital radiograph shows that latex balloon glued onto a Magic microcatheter is temporarily inflated in the parent artery at the level of the aneurysmal neck. Several coils have been positioned through the microcatheter placed in the aneurysm. Additional coils have been delivered to achieve occlusion.
D, Final angiogram at the end of the procedure shows occlusion of the aneurysm.

60-year-old woman. A, Cerebral angiogram (lateral projection) 1 month after partial occlusion of a ruptured wide-necked carotid-ophthalmic aneurysm performed emergently with a conventional GDC procedure. Remaining pouch has a triangular shape with a broad neck.
B, The first coils have been inserted into the aneurysm with the balloon inflated and bridging the aneurysmal neck.
C and D, Cerebral angiograms, lateral (C) and anteroposterior (D) projections, show complete occlusion of the aneurysm.

37-year-old-woman with SAH.
A, Cerebral angiogram (anteroposterior projection) reveals a large, wide-necked basilar artery tip aneurysm. Patient was not a candidate for surgery, and treatment with GDCs was impossible without using a protection balloon placed in front of the aneurysmal neck during coil deployment.
B, Digital radiograph shows the Solstice catheter has been advanced through the left vertebral artery, with the microwire anchored in the left P1 segment. After deployment of the coil into the inferior part of the aneurysm, and before its detachment, the balloon bridging the aneurysmal neck was slowly deflated.
C, Cerebral angiogram at the end of the procedure shows subtotal occlusion of the aneurysm. The right P1 segment is occluded, but the posterior cerebral artery is fed by the right posterior communicating artery. No neurologic deficit is observed.
D, Cerebral angiogram 15 months after treatment shows stability of the occlusion.
