Blunt-trauma carotid artery injury: mild symptoms may disguise serious trouble.
Injury to the carotid artery can occur in athletes by direct blow to the neck or by hyperextension of the neck. After such injury, symptoms may be mild or transient. Catastrophic complications such as stroke can occur if the injury is not recognized and treated. Neurologic changes such as transient weakness or transient unilateral blurred vision that occur after a hyperextension injury or a direct blow to the neck may indicate a carotid artery injury. A careful neurologic examination can help identify most carotid artery injuries, but because the symptoms of injury may not appear immediately, follow-up may be necessary. Treatment may consist of anticoagulation therapy or operative repair.
