• Cervical artery dissections include carotid or vertebral artery dissections and can be seen in patients of all ages, although they are a more common cause of stroke in young patients

 

  • Symptoms may be somewhat non-specific (headache, neck pain, dizziness) or can be more localized (partial Horner syndrome with carotid artery dissection, etc.)

 

  • Minor trauma (neck manipulation, yoga, minor falls, swimming) is considered a risk factor for spontaneous cervical artery dissection but more significant traumatic injury (blunt trauma to head/neck) is increasingly recognized as a cause of cervical artery dissection as well

 

  • Diagnostic imaging options include CTA, which has 90% sensitivity for detection of cervical artery dissection, and MRA, which has a sensitivity ranging from 75-100%

 

  • Patients with spontaneous cervical artery dissection and acute stroke are candidates for tPA in accordance with ischemic stroke guidelines

 

  • After initial acute management, patients are managed with anticoagulation or antiplatelet therapy (if tPA has been given, it is started 24 hrs after being administered)
