[Blunt injury to the neck caused by a seat belt. Stenosis of the internal carotid and vertebral arteries].

A 37-year-old woman sustained blunt trauma to the neck from a seat-belt in a car accident, which resulted in marked long-segment narrowing of the internal carotid artery with secondary occlusion of a main branch of the median cerebral artery as well as circumscribed circular stenosis of the right vertebral artery. Serial angiograms documented the course until there was almost complete recanalization of all affected vessels.
