Four patients suffered thrombosis of the carotid arterial system due to blunt trauma in the neck. The neurological symptoms in all developed a few hours after the injury. Three patients were operated on. None were improved. Two of them died, one of whom showed a hemorrhagic infarction of the brain at autopsy. The fourth patient was treated without operation and recovered without neurological residuals. Nonoperative treatment is recommended.
