Objective And ImportanceWide-necked cerebral aneurysms have been particularly difficult to treat using coil embolization. The introduction of the first intracranial flexible stent (Neuroform stent; Boston Scientific/Target, Fremont, CA) has provided a great advantage to this dilemma by forming a bridge across the aneurysm neck and allowing the packing of coils. Despite this advancement, some parent vessel bifurcation aneurysms can still remain elusive to single stent and coiling technique.Clinical PresentationA 55-year-old woman presented for a routine follow-up angiogram. Her past history was significant for a subarachnoid hemorrhage and clipping of an anterior communicating aneurysm with full recovery. An incidental new right middle cerebral artery aneurysm was found on the angiogram. We report here a case of an unruptured asymptomatic wide-neck middle cerebral artery bifurcation aneurysm that was treated with a novel endovascular repair.InterventionThe aneurysm was successfully treated using a double stent "Y" configuration and coil embolization technique using the Neuroform stent. Technical aspects are discussed. Perioperative management issues and potential pitfalls are also considered.ConclusionDouble stenting in "Y" configuration and coiling is feasible. This technique should increase the ability to endovascularly treat wide-necked aneurysms.
