Venous Plexus Vaginal

The venous plexus of the vagina (lat. plexus venosus vaginalis) is the venous plexus of the vaginal wall.

The venous plexus is one of the components of the pelvic venous system and plays an important role in the blood supply to the vagina and lower parts of the genitourinary system. It is formed from two sources: the vein surrounding the vagina, and the vein that passes through the vaginal septum and drains into the inferior vena cava.

The blood supply to the venous plexus occurs through the internal pudendal vein and the great vaginal vein, which are tributaries of the internal iliac vein. Venous drainage occurs through the uterine and ovarian veins, which drain into the superior and inferior vena cava, respectively.

The role of the vaginal venous plexus is to maintain normal blood flow in the vaginal wall and other tissues of the pelvis. It also plays an important role during pregnancy and childbirth, providing additional blood flow to the pelvic organs to maintain normal function and prevent tissue hypoxia.

However, in some cases, the venous plexus can be affected by various diseases such as varicose veins, thrombosis, infection, etc. This can lead to disruption of blood supply and cause various complications such as pain, swelling, bleeding, etc.
