Abstract
We presented a patient (57 yaers old, male) who had injuries of the anterior part of the neck including larynx, trachea, unilateral common carotid and vertebral arteries by the industrial accident. The patient died 6 days after the injury due to a thrombosis in the vertebral artery. Postmortum autopsy revealed the presence of thrombi not only in the vertebral artery but also in the common carotid artery, and they were caused by traumatic hyperextension of the neck during the accident. The present case indicates the necessity of paying an attention to the presence of thrombosis when treating a patient with traumatic neck injury.
