Dissecting Vertebral Artery Aneurysm Definition


Dissecting Vertebral Artery Aneurysm:

Dissection of the wall of the vertebral artery, leading to the formation of an aneurysm that may occlude the vessel. Thrombus formation may occur and give rise to emboli. Cervical fractures or related NECK INJURIES and CRANIOCEREBRAL TRAUMA are commonly associated conditions, although this process may occur spontaneously. Ischemia, infarction, and hemorrhage in the vascular distribution of the affected vertebral artery may complicate this condition.
