Endovascular embolization by parent artery reconstruction of a symptomatic fusiform posterior cerebral artery aneurysm using Onyx HD-500: a neurointerventional report.

Background And Purpose: Posterior cerebral artery aneurysms are treatment challenge for the neurosurgeon. Parent artery occlusion, trapping and bypass have been the classic treatment options for aneurysms in this location. With the introduction of newer embolic agents such as Onyx®, endovascular intervention is now a viable therapy for these aneurysms.
