Blunt carotid artery injury: devastating consequences of undetected pseudoaneurysm.

A case of delayed embolization of a traumatic pseudoaneurysm of the right common carotid artery, resulting in fatal cerebral infarction, is reported. This case emphasizes the importance to detect occult lesions to the carotid arteries after blunt neck injuries and to treat aggressively pseudoaneurysms located upstream to a cerebral vessel to prevent embolic complications.
