<< Cervical Artery Dissection: Early Recognition and Stroke Prevention (Stroke CME, Trauma CME and Pharmacology CME)

Points and Pearls Digest

  • Cervical artery dissections involve the carotid or vertebral arteries. An intimal tear creates a pseudolumen with intramural hematoma, which can later lead to vessel occlusion, thrombus formation, embolus, pseudoaneurysm, or rupture.
  • Cervical artery dissections from blunt trauma are caused by direct blow to the neck, hyperextension or contralateral rotation, intraoral trauma, or skull-base fractures. However, they can also occur spontaneously or with minor trauma. On average, symptoms occur 2 to 3 days after the traumatic event.
