Internal carotid artery trauma

The common carotid artery is the main artery of the head and neck. It branches into the internal and external carotid arteries at the upper edge of the thyroid cartilage. The incidence of traumatic embolism is higher in the internal carotid arteries. The internal carotid arteries mainly supply blood to the brain and vision, so the consequences of embolism are more serious. Internal carotid arterial embolism can occur in the cervical, petrous, cavernous sinus, or upper bed process. According to the analysis of 70 cases, 85% occurred in the neck and 10% in the rock bone. Internal carotid artery embolism mostly occurs after a contusion in the neck. Patients may have a transient ischemic attack, followed by neurological symptoms, which is a characteristic of internal carotid artery embolism. Relieving vasospasm and anticoagulant therapy can control the development of thrombus. If necessary, internal carotid artery thrombectomy is performed.
