Abstract
BACKGROUND Coil migration during endovascular treatment for an intracranial aneurysm is rare. When it occurs intraoperatively, it often mandates prompt endovascular retrieval or, as a salvage maneuver, microsurgical extraction if it fails endovascularly. OBSERVATIONS The authors presented a case of immediate coil migration during embolization of a giant intracranial cavernous segment of the internal carotid aneurysm. The patient immediately underwent emergency surgical extraction after unsuccessful endovascular retrieval attempts. The migrated coil was successfully removed through the M1 segment of the middle cerebral artery. The patient had full recovery without new neurological deficits. Four years after the incident, she was living independently. Previous case reports of emergency surgical removal of immediate coil migration were provided. LESSONS Surgical extraction of migrated coil after unfeasible endovascular retrieval served as an alternative salvage procedure. Hybrid neurological angiography in the operating suite may prevent unnecessary transfer and provide better real-time visualization of the migrated coil.
