What’s the difference between carotid artery dissection and cervical artery dissection?

There are four main arteries in your neck: two carotid arteries and two vertebral arteries. Collectively they’re called the cervical arteries. A cervical artery dissection is a separation or tear in the wall of any of these four arteries.

A carotid artery dissection is a tear specifically in one of the two carotid arteries. It’s a type of cervical artery dissection.
