As a venous sinus, the cavernous sinus receives blood from the superior and inferior ophthalmic veins and from superficial cortical veins, and is connected to the basilar plexus of veins posteriorly. The cavernous sinus drains by two larger channels, the superior and inferior petrosal sinuses , ultimately into the internal jugular vein via the ...
The medial angle of the eye, nose and lips (known as the danger triangle of the face) usually drain through the facial vein, via the superior ophthalmic vein through the cavernous sinus. An infection of the face may spread to the cavernous sinus through the superior ophthalmic vein. [6] This can cause cavernous sinus thrombosis. [6]

The central retinal vein (retinal vein) is a vein that drains the retina of the eye.It travels backwards through the centre of the optic nerve accompanied by the central retinal artery before exiting the optic nerve together with the central retinal artery to drain into either the superior ophthalmic vein or the cavernous sinus.
Oblique section through the cavernous sinus. The cavernous segment, or C4, of the internal carotid artery begins at the petrolingual ligament and extends to the proximal dural ring, which is formed by the medial and inferior periosteum of the anterior clinoid process. The cavernous segment is surrounded by the cavernous sinus.
The plexus drains all veins that correspond to the branches of the maxillary artery (however, much of the blood delivered by the maxillary artery is returned by other routes), as well as two additional veins. [2] It receives the following veins: [citation needed] sphenopalatine; middle meningeal; deep temporal (anterior & posterior) pterygoid ...
Thrombophlebitis of the facial vein, (inflammation of the facial vein with secondary clot formation) can result in pieces of an infected clot extending into the cavernous sinus, forming thrombophlebitis of the cavernous sinus. Infections may spread from the facial veins into the dural venous sinuses. Infections may also be introduced by facial ...
The superficial middle cerebral vein (superficial Sylvian vein) begins on the lateral surface of the hemisphere.It runs along the lateral sulcus [1] to empty into either the cavernous sinus, [1] [2] or sphenoparietal sinus. [1]
