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 pterygoid plexus of veins becomes the maxillary vein. The maxillary vein and the superficial temporal vein later join to become the retromandibular vein. The posterior branch of the retromandibular vein and posterior auricular vein then form the external jugular vein, which empties into the subclavian vein. [citation needed]
The posterior internal vertebral venous plexus [2] consists of two veins situated - one on either side - upon the anterior aspect of the vertebral arches and ligamenta flava. They form anastomoses with posterior external plexuses by way of veins passing through or between the ligamenta flava.
The pampiniform plexus (from Latin pampinus 'tendril' and forma 'form') is a venous plexus – a network of many small veins found in the human male spermatic cord, and the suspensory ligament of the ovary.

The vesical venous plexus is a venous plexus situated at the fundus of the urinary bladder. It collects venous blood from the urinary bladder in both sexes, from the accessory sex glands in males, and from the corpora cavernosa of clitoris in females (via the v. dorsalis profunda clitoridis). [ 1 ]
The rectal venous plexus (or hemorrhoidal plexus [2]) is the venous plexus surrounding the rectum. [3] It consists of an internal and an external rectal plexus. [4]: 598 [5]: 294 It is drained by the superior, middle, and inferior rectal veins.
