In this article, we shall consider the venous drainage of the CNS. We will discuss the veins of the brain, the dural venous sinuses, their drainage into the systemic circulation, and the venous drainage of the spinal cord.

The venous system of the head and neck collect deoxygenated blood and return it to the heart. The venous drainage can be divided into three parts: Venous drainage of the brain and meninges – drained by the dural venous sinuses. Venous drainage of the scalp and face – drained by veins synonymous with the arteries of the face and scalp. These ...

It receives venous drainage from the falx cerebri itself, and numerous small venous veins which drain the medial surface of the cerebral hemispheres. Posteriorly, it combines with the great cerebral vein to form the straight sinus .

After emptying into the dural venous sinuses, most cerebral venous blood flows into the internal jugular veins before it is returned to the heart. This article discusses the venous drainage of the brain and relevant clinical conditions such as cavernous sinus thrombosis.

Most superficial veins drain into the superior sagittal sinus, cavernous sinus, transverse sinus, and inferior sagittal sinuses. Most deep veins drain into the internal cerebral vein, and some drain into the basal vein of Rosenthal, which head toward the great cerebral vein of Galen.
