Usefulness of the Pipeline Embolic Device for Large and Giant Carotid Cavernous Aneurysms

Conventional coil embolization for large carotid cavernous aneurysms (CCAs) has limited utility due to its inability to prevent recurrences and reduce mass effect. Trapping of the parent artery may have a risk of ischemic complications due to intracranial perfusion disorders. We successfully treated 24 patients with large CCAs using a flow diverter (Pipeline？ embolic device: PED), and this report discusses the safety and efficacy of this method
