Internal carotid artery occlusion after trauma

Direct or indirect trauma to the neck or cervical spine causes internal carotid artery or vertebral artery endometrial damage. On this basis, inflammation and bleeding occur, and then thrombus is formed locally and spreads to the distal end, causing cerebral infarction corresponding to blood supply. After trauma, the internal carotid artery occlusion can spread upwards and affect the ophthalmic artery and anterior choroid artery to the front of the willis ring, and even the anterior and middle cerebral arteries. Lighter patients have limited neurological dysfunction, and severe ones can cause massive cerebral infarction and deep coma. One third of these patients are often life-threatening.
