Endovascular treatment, including transarterial embolisation and transvenous embolisation, is generally considered effective for treating carotid-cavernous fistula. Immediate cranial nerve palsy following the procedure is the most common complication, but it usually resolves spontaneously. The authors report two cases of late-onset abducens nerve palsy after successful obliteration of direct carotid-cavernous fistulas, both of which required strabismus surgery.
