The dural venous sinuses receive blood from the veins associated with the cerebrum, cerebellum and brainstem. They also receive contributions from the diploic and emissary veins (draining the cranium and the scalp, respectively).
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.
Dural venous sinuses are venous channels located intracranially between the two layers of the dura mater (endosteal layer and meningeal layer) and can be conceptualised as trapped epidural veins. Unlike other veins in the body, they run alone and not parallel to arteries.

Dural venous sinuses are a group of sinuses or blood channels that drains venous blood circulating from the cranial cavity. It collectively returns deoxygenated blood from the head to the heart to maintain systemic circulation.
Venous sinus thromboses (VST) are venous blood clots of the major veins of the brain. They can be provoked or unprovoked, and the signs and symptoms thereof will depend on the location and extent of the clot.
venous sinus, in human anatomy, 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. Unlike veins, these sinuses possess no muscular coat.
Cerebral venous sinus thrombosis (CVST) describes the presence of a thrombus within one of the dural venous sinuses. The thrombus occludes venous return through the sinuses, and causes an accumulation of deoxygenated blood within the brain parenchyma.
Cerebral venous thrombosis (CVT) is the presence of a blood clot in the dural venous sinuses, the cerebral veins, or both. 1 Among those with stroke, CVT represents only 0.5% to 3%. 2 Registry-based and cohort studies suggest that CVT affects predominantly individuals <55 years of age, with two-thirds occurring in women. 2 With regard to ...
The dural venous sinuses are spaces between the periosteal and meningeal layers of dura mater, which are lined by endothelial cells. They collect venous blood from the veins that drain the brain and bony skull, and ultimately drain into the internal jugular vein.
