Vein structure The walls of your veins are made up of three different layers. The deep venous system consists of the Internal Cerebral Vein and in some sense the Basal Vein of Rosenthal. Formed from the union of the external and internal iliac veins the common illiac veins join to form the inferior vena cava. This blood is provided by the heart which pumps oxygenated blood to the brain through a system of arteries and blood vessels. This pathway is called the hepatic portal system.

Unpaired Dural Venous Sinuses of brain. The cerebral venous system somewhat unlike the majority of the rest of the body does not even remotely follow the cerebral arterial system. Venous outflow from the cerebral hemispheres occurs via cortical veins within the pia mater on the surface of the brain as well as deep central veins.

4 rows The veins of the brain are thin-walled valveless and pierce the arachnoid mater and meningeal. The cerebral veins lack muscular tissue and valves. SUPERFICIAL VENOUS SYSTEM The superficial venous system comprises the.

The purpose of this study was to evaluate the use of MR venography in the depiction of the normal intracranial venous anatomy and its variants to assess its potential pitfalls in the diagnosis of dural venous sinus thrombosis and to. Both systems are connected via anastomoses.
