Traumatic vertebral artery pseudoaneurysm following chiropractic manipulation.

A vertebral artery pseudoaneurysm accompanied by serious neurological injury was seen in a 42-year-old woman who had undergone chiropractic manipulation of the neck. Such manipulation is a potential cause of neurological injury due to trauma to the cervical spine and the major vessels of the neck. The arterial pattern in this case was similar to that of angiodysplasia except for narrowing and irregularity of the vertebral artery.
