Pipeline embolization device treatment of internal carotid artery terminus aneurysms.

Background: The pipeline embolization device (PED) is approved for the treatment of large aneurysms of the proximal internal carotid artery (ICA). Its off-label application in treating aneurysms located specifically at the ICA terminus (ICA-T) has not been studied.
