Endovascular Treatment of a Giant Extracranial Carotid Artery Pseudoaneurysm in a Child Using Vascular Plugs.

Carotid artery pseudoaneurysm is a rare but serious complication of a retropharyngeal abscess in children. We report the first case of treating an unruptured mycotic pseudoaneurysm of the extracranial internal carotid artery (ICA) in a pediatric patient with vascular plugs. A 3-year-old patient presented with airway compromise and signs of neck sepsis. Successful embolization of the pseudoaneurysm was achieved with 2 Amplatzer vascular plugs to close the front and back door. The patient did not have any neurological deficit. Repeat imaging with ultrasound and computed tomography confirmed no recurrence of the pseudoaneurysm.
