The patient was undergoing a coil embolization procedure in the internal carotid artery using penumbra coil 400 (pc400) coils.The procedure was successful with no complications.However, the next day, magnetic resonance imaging revealed small foci of silent ischemia in the left cerebral hemisphere of the patient.The relationship of the pc400 coils to the ischemia is uncertain; however the relationship of the procedure to the ischemia is definite.
