Internal Carotid Artery Dissection
Internal carotid artery dissection typically produces pain localized to the face (see Chapter 14). It is often accompanied by ipsilateral sympathetic dysfunction (Horner syndrome) due to involvement of the sympathetic fibers in the wall of the carotid artery (see Chapter 10, Fig 10-4).
