Duplicated basilar artery
WebThe vertebrobasilar system (VBS) consists in the intracranial parts of the vertebral arteries (VAs), the basilar artery (BA) and its branches. The presence of a duplication at the level of the intracranial segment of VA (V4) is generally an incidental finding, but may be associated with aneurysms or arteriovenous malformations. WebThe basilar artery is a blood vessel at the back of your brain. It supplies oxygen-rich blood to portions of your brain and central nervous system. The basilar is the main artery that carries blood to the back portion of your brain. It forms where the blood vessels that extend through your spinal cord ( vertebral arteries) come together.
