What is Vertebral Artery Dissection?!
Question: my stepmother was diagnosed with this and I didn't really understand it, and would like to know more.
Answers:
An arterial dissection is basically a tearing of an inner layer of the wall of an artery. This torn inner layer forms a “flap”. Blood flows underneath this flap in the artery and because of this, the artery becomes smaller and sometimes is even closed off entirely. Blood flow to the brain can be compromised and can cause a stroke. It requires treatment with blood thinners.
Other Answers:
Vertebral means spine, so I'm going to field a guess that it's something to do with an artery connected to the back rupturing.
