Pipeline Embolization of Posterior Communicating Artery Aneurysms Associated with a Fetal Origin Posterior Cerebral Artery

The Pipeline Embolization Device (PED; Medtronic Neurovascular, Irvine, CA) received FDA approval in 2011 for the treatment of aneurysms larger than 10mm in size with necks larger than 4mm located from the petrous to superior hypophyseal segments of the internal carotid artery (ICA). Although successful off-label use of the device to treat ICA aneurysms smaller than 10mm in size has been widely reported [1 –7], Pipeline embolization of posterior communicating artery (PComA) aneurysms associated with a hypoplastic ipsilateral P1 segment, or fetal origin posterior cerebral artery (PCA), raises two important concerns.
