A 44-year-old man presented with traumatic aneurysm of the left ophthalmic artery. The first coil embolization intervention achieved relatively tight packing of the aneurysm and the parent artery. After 5 months, a second embolization procedure was required because of recurrence of the aneurysm with transition of the intraaneurysmal coil formation. No recurrence occurred after the second embolization. We thought that the first embolization might have prevented catastrophic rupture, whereas the second embolization resulted in complete obliteration of the aneurysm. No entity of the aneurysmal wall formation of the current traumatic aneurysm in the acute stage may have resulted in the recanalization of the aneurysm followed by the second intervention. The stability of the wall in the chronic stage may correlate with the complete obliteration.
