A 22-year-old man with primitive trigeminal artery-cavernous fistula was admitted to our hospital. Embolization with Guglielmi detachable coils and microcoils was attempted on the fistula from the internal carotid artery. The last microcoil was incorrectly released to the basilar artery through the primitive trigeminal artery. The misplaced microcoil was eventually retrieved by goose-neck snare. There was no related complication in the follow-up period.
