Uterine vein

The uterine vein refers to a group of blood vessels found near the genitalia on the female body. These veins are considered part of a network of blood vessels called the uterine venous plexus. The uterine vein facilitates the flow of blood within the plexus.

The uterine plexus and uterine vein emerge from the sides of the uterus, which is where a fetus develops before birth. These veins lie in close proximity to the vagina. The functional purpose of the uterine veins and plexus is to help deliver blood flow from the uterus to the heart. Once the blood has circulated through the uterine plexus, it leaves the uterus by draining through the uterine veins.

There are two uterine veins, one on either side of the uterus near the bottom of the plexus. The veins then converge with the hypogastric vein. The uterine vein also connects with the ovarian vein. The vaginal veins that stem from the vaginal venous plexus may drain into the uterine vein in some women.

This blood vessel may be prone to uterine vein thrombosis, a serious medical condition in which a blood clot develops within the vessel and obstructs the flow of blood.
