title: [Successful Stent-Assisted Coil Embolization of Fusiform Aneurysm in P2 Segment of Posterior Cerebral Artery:A Case Report].
abstract: We report a case of a fusiform aneurysm in the P2 segment of the posterior cerebral artery treated with stent-assisted coil embolization. A 44-year-old woman presented with an unruptured fusiform aneurysm in the left posterior cerebral artery. Stent-assisted coil embolization was performed using a "down-the-barrel" view to preserve the parent artery. The postoperative course was uneventful, and MRI showed no evidence of cerebral infarct. The patient was discharged 12 days after surgery, with no neurological deficit. Complete occlusion of the aneurysm and patency of the parent artery were observed on MR angiography at a 3-months follow up. Stent-assisted coil embolization can therefore be an effective alternative to parent artery occlusion in P2 segment fusiform aneurysms of the posterior cerebral artery.
