Root artery ischemia syndrome supplying blood to cervical spinal cord

From the anatomical point of view, the root artery of the cervical segment mainly comes from the second segment of the vertebral artery and the ascending branch of the thyroid neck stem. Because it runs along the spinal nerve root, it is called the root artery. At the inner mouth of the root canal, the root artery is divided into the anterior and posterior root arteries, which participate in the formation of the anterior central spinal artery and the posterior spinal artery, respectively, and mainly supply blood to the cervical spinal cord at 4 to 7 segments of the neck. Symptoms produced when the root artery branch is involved are consistent with the aforementioned ldquo; anterior central spinal artery ischemic syndrome rdquo; and ldquo; posterior spinal artery ischemic syndrome rdquo ;, so they will not be repeated. This section mainly describes a series of problems caused by obstruction of the root artery before branching.
