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 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]
In vertebrates, a venous plexus is a normal congregation anywhere in the body of multiple veins. [1] A list of venous plexuses: This list is incomplete; ...
The vaginal venous plexus lies around the sides of the vagina. [1] Its branches communicate with the uterine venous plexuses, vesical venous plexus, and rectal venous plexuses. It is drained by the vaginal veins, one on either side. These eventually drain into the internal iliac veins (hypogastric veins). [1] [2]
The vesical veins are veins in the pelvis that drain blood from the urinary bladder. The vesical veins receive blood from the vesical venous plexus and are tributaries of the internal iliac veins . [ 1 ]
While one may expect the female to have an equal prevalence of pelvic compression syndrome due to the identical embryological origin of the valveless pampiniform plexus, this condition is thought to be underdiagnosed due to the broad differential of the pain pattern: unilateral or bilateral pain, dull to sharp, constant to intermittent pain worsening with any increase in abdominal pressure.
Pelvic congestion syndrome, also known as pelvic vein incompetence, is a long-term condition believed to be due to enlarged veins in the lower abdomen. [1] [7] The condition may cause chronic pain, such as a constant dull ache, which can be worsened by standing or sex. [1] Pain in the legs or lower back may also occur. [1]
In addition to its function in venous return from the testes, the pampiniform plexus also plays a role in the temperature regulation of the testes. It acts as a countercurrent heat exchanger, cooling blood in adjacent arteries. An abnormal enlargement of the pampiniform plexus is a medical condition called varicocele.
