intervertebral vein

A vein that drains blood from the vertebral column and intervertebral discs. In the neck, it is tributary of into the vertebral veins. In the thorax, it is tributary of the posterior intercostal veins. In the lumbar and sacral regions, it is tributary of the lumbar and lateral sacral veins

Câu hỏi thường gặp

What is an intervertebral vein?
An intervertebral vein is a small vein that drains blood from the vertebral column and intervertebral discs. These veins pass through intervertebral foramina alongside spinal nerve roots and connect internal and external vertebral venous plexuses to the segmental veins of each region.
Where are intervertebral veins located?
Intervertebral veins are located within and around the vertebral column, running through the intervertebral foramina between adjacent vertebrae. In the neck they drain into the vertebral veins, in the thorax into the posterior intercostal veins, and in the lumbar and sacral regions into the lumbar and lateral sacral veins.
What is the function of intervertebral veins?
Intervertebral veins drain blood from the vertebral column, intervertebral discs, and the vertebral venous plexuses. They serve as conduits connecting the internal vertebral venous plexuses within the spinal canal to the external vertebral plexuses and segmental veins outside the vertebral column.
What conditions may be associated with intervertebral veins?
The intervertebral veins are part of a valveless vertebral venous system that may be involved in the spread of certain infections or metastatic processes through the vertebral column. They are also relevant in the context of spinal vascular anatomy and potential bleeding during spinal surgery.
How are intervertebral veins examined?
Intervertebral veins are generally too small for routine imaging but may be assessed indirectly through MR venography or CT venography in cases of suspected vascular malformation or spinal vascular pathology. They are encountered directly during spinal surgery.
