Giant pseudoaneurysm of the internal carotid artery causing upper airway obstruction in a 10-month-old infant treated by endovascular occlusion and surgical drainage.

A rare case of acute upper airway obstruction caused by a giant compressing pseudoaneurysm of the left internal carotid artery is presented. The pseudoaneurysm developed one month after a deep neck space infection, and an emergency tracheal intubation was necessary. The treatment consisted of endovascular occlusion of the left internal carotid artery and surgical drainage of the pseudoaneurysm with complete resolution of the symptoms.
