What is Batson venous plexus?
What is Batson venous plexus?
Batson’s venous plexus is a system of paravertebral veins that connect pelvic and thoracic vessels to the intraspinal (basivertebral) veins. It was first described in 1940 to explain a route for spread of metastases and infection that was separate to the lymphatic system.
Where is the Batson plexus?
The Batson venous plexus (Batson veins) is a network of valveless veins in the human body that connect the deep pelvic veins and thoracic veins (draining the inferior end of the urinary bladder, breast and prostate) to the internal vertebral venous plexuses.

How does the Pampiniform plexus regulate temperature?
The pampiniform plexus helps regulate the temperature of the testes by acting as a “heat exchange” mechanism to cool down the blood. The arteries supplying the testes run through the plexus where the blood is cooled from abdominal arterial temperature to testicular temperature.
Which of the following veins has no valves?
Background: The ophthalmic and facial veins are frequently stated to be devoid of valves, facilitating the spread of infection from the mid-face to the cavernous sinus.
Where is the Basivertebral nerve?
What is the Basivertebral Nerve? The basivertebral nerve enters the vertebral bodies of the spinal column. Within the vertebral body, the nerve branches and supplies the endplates or the upper and lower surfaces of the vertebral body.
What passes through Basivertebral foramen?
These foramina can be single (as seen in the image) or multiple. The basivertebral veins represent a communication that allows drainage of the vertebral body venous sinuses into the extensive complex venous network of the internal venous plexuses that surrounds the spinal cord.
What is the lymphatic drainage of the bladder?
The primary lymphatic drainage site for bladder cancer includes the internal iliac, external iliac, obturator, and presacral lymph nodes. Secondary drainage sites include the common iliac, para-aortic, interaortocaval, and paracaval lymph nodes (Figures 1, 2) (6, 7).
