Definitions for vertebrobasilar insufficiency

Here are all the possible meanings and translations of the word vertebrobasilar insufficiency.


  1. Vertebrobasilar insufficiency

    Vertebrobasilar insufficiency, or vertebral basilar ischemia, refers to a temporary set of symptoms due to decreased blood flow in the posterior circulation of the brain. The posterior circulation supplies blood to the medulla, cerebellum, pons, midbrain, thalamus, and occipital cortex. Therefore, the symptoms due to VBI vary according to which portions of the brain experience significantly decreased blood flow. In the United States, 25% of strokes and transient ischemic attacks occur in the vertebrobasilar distribution. These must be separated from strokes arising from the anterior circulation, which involves the carotid arteries.
