Intercavernous sinus

The intercavernous sinus (anterior and posterior) are dural venous sinuses and connect the left and right cavernous sinuses, along with the basilar venous plexus. They lie in the anterior and posterior borders of the diaphragma sellae. Additional small venous sinuses in the base of the pituitary fossa drain into the intercavernous sinuses, and are a cause of bleeding during transphenoidal hypophysectomy.
