Anatomy

The Pudendal Venous Plexus is situated in the deep perineum and is closely associated with the pudendal nerve and internal pudendal artery. It is formed by the confluence of several smaller veins that drain the perineal region, including the deep dorsal vein of the penis or clitoris, and the perineal veins.

Function

The primary function of the Pudendal Venous Plexus is to facilitate the venous return of blood from the pelvic organs and structures. It also plays a role in the thermoregulation of the pelvic region, helping to maintain a constant temperature in this area.

Clinical Significance

The Pudendal Venous Plexus is clinically significant as it can be a site of varicose vein formation, particularly in conditions such as pelvic congestion syndrome. It is also important in the surgical management of certain conditions, such as prostate cancer and rectal cancer, where an understanding of its anatomy can aid in the preservation of vital structures during surgery.
