Abstract

Giant intrapetrous internal carotid aneurysms (petrous ICA aneurysm) are rare. A giant petrous ICA aneurysm presenting with otorrhagia and coil exposure to the external auditory meatus (EAM) after endovascular treatment has never been documented before. The authors report here a case of successful surgical trapping with bypass intervention of a giant petrous ICA aneurysm presenting with coil exposure after endovascular treatment. A 58-year-old man presented with persistent otorrhagia having been admitted to our hospital because of the recurrence of a giant petrous ICA aneurysm after repeated embolization treatments with coils. An electronic otoscope examination demonstrated that a piece of coil escaped into his right EAM. After multidisciplinary consultation, an extracranial-intracranial (EC-IC) bypass with ICA occlusion and coil removal with a closed EAM filling were performed in stages. The patient recovered quickly without any neurological deficits. A digital subtraction angiography confirmed the absence of the aneurysm and patency of the bypass graft.
