Functional Cerebral Venous Anatomy from the Viewpoint of Venous Collaterals Part I, Supratentorial Superficial and...

Supratentorial veins are divided into superficial and deep venous systems. 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. The functional anatomy of the supratentorial cerebral veins can be explained by dividing them into (1) veins on the lateral surface of the cerebral hemisphere, (2) the basal vein of Rosenthal system, and (3) the internal cerebral vein system. Many anastomotic channels exist between the superficial venous systems, veins at the base of the brain, and transcerebral veins. To understand and prevent adverse neurointerventional effects, in this study, we review the cerebral venous anatomy from the viewpoint of venous collaterals.
