[1][2] They receive blood from the cerebral veins, and cerebrospinal fluid (CSF) from the subarachnoid space via arachnoid granulations.

A dural venous sinus, in human anatomy, is any of the channels of a branching complex sinus network that lies between layers of the dura mater, the outermost covering of the brain, and functions to collect oxygen-depleted blood.

Paired venous sinus [3] The walls of the dural venous sinuses are composed of dura mater lined with endothelium, a specialized layer of flattened cells found in blood and lymph vessels.

Other common causes of dural sinus thrombosis include tracking of infection through the ophthalmic vein in orbital cellulitis.

While rare, dural sinus thrombosis may lead to hemorrhagic infarction or cerebral edema with serious consequences including epilepsy, neurological deficits, or death.
