Podcast # 418: Vertebral Artery Dissection

Author: Don Stader, MD

Educational Pearls:

  • Vertebral artery dissection (VAD) contributes to just 2% of strokes overall but ~25% of strokes for patients < 30
  • VAD is associated with minor trauma (chiropractic manipulation, yoga), typically with neck extension and rotation.
  • VAD can cause posterior stroke symptoms (vertigo, diplopia, Horner's Syndrome, Wallenberg Syndrome)
  • Overall a good prognosis with around 50% of patients recovering without lasting neurologic deficits.
