Vertebral Artery Dissection: a Contemporary Perspective
Cristina TIU, Elena TERECOASA, Nicolae GRECU, Raluca NISTOR, Smaranda FRANGU and Florina ANTOCHI
ABSTRACT
Arterial dissections are among the most frequent causes of stroke in young adults. Usually they are associated with trauma, but as the modern imaging tools are evolving, more dissections are being diagnosed and more etiologies are being described. Vertebral artery dissections (VADs) have the distinct particularity that they can cause ischemic stroke (in the brainstem, cerebellum or even the spinal cord), but also subarachnoid hemorrhage, when the dissection occurs in the intracranial segment of the vertebral artery. We present a review of the literature, going over etiology, clinical aspects, diagnosis and treatment of VADs and we illustrate the theory with three different types of VAD from our clinical experience.
