  • Consider cervical artery dissection as the source of stroke in patients younger than age 40.
  • About 20% of such strokes are due to carotid artery or vertebral artery dissections.
  • Of these, internal carotid artery dissections are the most common.
  • These patients often present with a triad of neck and head pain, Horner's syndrome, and pulsatile tinnitus.
  • MRI/MRA is the best non-invasive diagnostic modality for arterial dissection.  Angiography may needed for confirmation.
