Re-rupture of cerebral aneurysms often occurs at their blebs, and the treatment of cerebral aneurysms harboring blebs has been considered difficult. To prevent rupture during embolization, the authors have tried to deliver coils only into aneurysm domes, without inserting coils, a microcatheter, or a microguidewire into the blebs. Here, to prove such a treatment strategy, the authors report early experience in 3 cases with cerebral aneurysms harboring blebs.
