Intercavernous sinus

The intercavernous sinuses (anterior, posterior, and inferior) are variable dural venous sinuses that connect the left and right cavernous sinuses. Some authors also include in this group the basilar venous plexus (basilar sinus) and sinus of the dorsum sellae 2. The anterior, posterior, and inferior intercavernous sinuses lie in the anterior, posterior, and inferior borders of the sella turcica. These venous sinuses, especially the anterior and inferior intercavernous sinuses, are prone to bleeding during transsphenoidal surgery of the sellar region 2.
