Where is prostatic venous plexus located?

What is Batson plexus?
Batson’s venous plexus is a system of paravertebral veins that connect pelvic and thoracic vessels to the intraspinal (basivertebral) veins. It was first described in 1940 to explain a route for spread of metastases and infection that was separate to the lymphatic system.

Qu’est-ce que le plexus interne?
Le plexus interne présente une série de chambres disposées en cercle autour du tube, immédiatement au-dessus de l’orifice anal, et reliées par des branches transversales. La partie supérieure du plexus externe est drainée par la veine rectale supérieure qui forme le début de la veine mésentérique inférieure, un affluent de la veine porte.
