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. [1]
The Batson venous plexus, which communicates the posterior intercostal vessels with the vertebral plexus, lacks valves so blood can flow in both directions. The clinical importance of this venous communication is that it represents an important phase in the establishment of vertebral metastases [6] and neuroschistomiasis. [7]
The external vertebral venous plexuses (extraspinal veins) consist of anterior and posterior plexuses which anastomose freely with each other. They are most prominent in the cervical region [ 1 ] where they form anastomoses with the vertebral , occipital , and deep cervical veins .

Beginning in 1937 Batson began a series of injection experiments investigating the anatomy and physiology of the cerebrospinal venous system. [2] His carefully documented results demonstrated the continuity of the venous systems of the brain and the spine, as injections of contrast dyes into venous systems feeding into the spinal venous plexus led to the appearance of contrast material in the ...
The prostatic veins form a well-marked prostatic plexus which lies partly in the fascial sheath of the prostate and partly between the sheath and the prostatic capsule. [ citation needed ] It collects blood from the prostate, and (via the v. dorsalis profunda clitoridis) the corpora cavernosa of penis . [ 1 ]
This plexus ends in a single trunk, which emerges from the transverse foramina of the sixth cervical vertebra, and opens at the root of the neck into the back part of the innominate vein near its origin, its mouth being guarded by a pair of valves. On the right side, it crosses the first part of the subclavian artery.
The venous plexus of hypoglossal canal [Note 1] is a small venous plexus surrounding the hypoglossal nerve (cranial nerve XII) [1] as it passes through the hypoglossal canal. [3] [4] [5] [better source needed] The plexus connects with the occipital sinus (intercranially), inferior petrosal sinus (intercranially), internal jugular vein (extracranially), [1] condylar vein, and paravertebral ...
