Nasopharyngeal Migration of Coils Following Embolization of a Traumatic Pseudoaneurysm of the Internal Carotid Artery: A Case Report
Jonathan Pimiento Figueroa, Mariana Escobar Howard, Pablo Escudero Pineda, Sebastian Orozco Arteaga
TL;DR
A rare case of a traumatic pseudoaneurysm in the carotid artery was treated with endovascular therapy, but later required additional treatment due to coil migration into the nasal area.
Contribution
This case report highlights a rare late complication of coil extrusion following embolization of a traumatic pseudoaneurysm.
Findings
A 28-year-old male developed coil extrusion into the nasal cavity after treatment of a traumatic carotid pseudoaneurysm.
The complication was successfully managed using endovascular and endoscopic approaches.
Endovascular therapy remains effective for traumatic pseudoaneurysms despite rare late complications.
Abstract
Post-traumatic pseudoaneurysms of the internal carotid are a rare but potentially fatal cause of epistaxis; they are associated with fractures of the base of the skull with involvement of the carotid canal. Endovascular management is the preferred therapeutic strategy, with optimal long-term results and low complication rates. Complications may include thromboembolic events, infarction of perforating arteries, and rupture of the pseudoaneurysm. We present a case of a 28-year-old male with a post-traumatic pseudoaneurysm of the internal carotid who was managed with endovascular therapy. A late complication was the extrusion of the embolization material into the nasal cavity and nasopharynx, which was safely and effectively treated through endovascular and endoscopic approaches.
