Anatomical terminology] |
The basivertebral veins are large, tortuous
They emerge from the vertebral bodies horizontally through foramina in the bone. Anteriorly, they drain into the external vertebral venous plexuses; posteriorly, they drain into the anterior internal vertebral venous plexus by way of transverse vessels that bridge the two vertical anterior internal vertebral plexus vessels across the midline.[1]
Anatomy
They are contained in large, tortuous channels in the bony substance of the vertebral bodies akin to those in the
The basivertebral veins are the main tributaries of the internal vertebral venous plexus.[4]
Development
The basivertebral veins become enlarged in advanced age.[1]
Clinical significance
It is unclear whether basivertebral veins contain functional venous valves; blood flow through basivertebral veins may be reversible, suggesting a possible mechanism for metastatic spread of e.g. prostatic cancer to the spine during temporary blood flow reversals (e.g. during periods of elevated intra-abdominal pressure or during postural alterations).[1]
