Carotid and vertebral artery dissections.

ABSTRACT

Dissections of the carotid and vertebral arteries are a common cause of stroke in young adults. The diagnosis may be missed because the typical signs and symptoms are often delayed in onset, or easily confused with other more commonly encountered entities. Dissections of the carotid and vertebral arteries may occur spontaneously or may accompany mild to severe trauma. They present with a variety of findings including headache, neck and face pain, Horner's syndrome, or stroke.
