RESUMO
In Eagle syndrome, elongated styloid processes may provoke internal carotid dissection and pseudoaneurysm causing stroke and data regarding possible complications or long-term results of pseudoaneurysm treatment using a flow diverter are limited. We report a case of a dissection-related pseudoaneurysm in the left cervical carotid artery treated by implantation of a flow diverter. Follow-up imaging of the flow diverter showed fracture of a continuous radiopaque marker at 3 months and fracture of a second continuous radiopaque marker at 7 months, while contrasting of the vessel was preserved. At the time of angiographic control (8 months after implantation), the flow diverter and the extracranial left internal carotid artery were occluded, and the patient did not experience any symptoms throughout the period.
