Removal of a Distally Migrated and Wedged Small Detachable Coil Using a 4MAX Penumbra Reperfusion Catheter

Migration of a detachable coil during embolization of a cerebral aneurysm is not rare [1, 2, 3, 4, 5, 6]. Surgery and techniques using wires, snares, and stent-retrievers have been used for the retrieval of the migrated coils [1, 2, 3, 4, 5]; however, surgical removal is time-consuming and the other endovascular techniques need to introduce the devices through the coil mass for removal. Recently, a small coil which had migrated and became wedged in the distal posterior cerebral artery, was successfully retrieved using a 4MAX reperfusion catheter (Penumbra, Alameda, CA, USA).
