The vertebral venous plexuses (also known as the Batson venous plexus) are a network of veins located within the vertebral column. These plexuses are divided into two main groups: the internal vertebral venous plexus and the external vertebral venous plexus. They play a crucial role in the venous drainage of the spinal cord and the vertebrae.
Anatomy
The vertebral venous plexuses are divided into:
- Internal vertebral venous plexus: This plexus is located within the vertebral canal and is situated between the dura mater and the vertebrae. It is further divided into anterior and posterior internal vertebral venous plexuses.
- External vertebral venous plexus: This plexus surrounds the vertebrae and is also divided into anterior and posterior components.
Function
The vertebral venous plexuses are valveless veins that provide a pathway for venous blood to return from the spinal cord and the vertebrae to the systemic circulation. They are important for maintaining the cerebrospinal fluid pressure and play a role in the spread of metastatic cancer cells and infections due to their valveless nature.
Clinical significance
The vertebral venous plexuses are clinically significant because they can serve as a route for the spread of cancer and infections. Due to the lack of valves, increased intra-abdominal or intrathoracic pressure can cause a reversal of blood flow, potentially leading to the spread of disease.
