Answer

Vertebral artery dissection (VAD) is an increasingly recognized cause of stroke in patients younger than 45 years. [4, 14, 15, 16, 17] Although its pathophysiology and treatment closely resemble that of its sister condition, carotid artery dissection (CAD), the clinical presentation, etiology, and epidemiologic profile of VADs are unique. In particular, advances in imaging have contributed to growing awareness of this entity. [8]
