Answer

Patients with intracranial vertebrobasilar dissection constitute a more severely affected subgroup of all patients with verterbral artery dissection (VAD). [13]

The presentation of a dissection involving the intracranial portion of the vertebral artery (segment IV) is characterized by rapidly progressive neurologic deficits, including depressed consciousness.

VAD is associated with subarachnoid hemorrhage, brainstem infarctions, and high mortality rate. [13]
