Cerebral Venous System


Cerebral Sinuses and Veins

There are 11 venous sinuses in total, between periostial and meningeal layers of dura.

Veins of significance include Thalamostriate, Superior Anastomotic Vein (of Trolard), Internal Cerebral Vein, Great Cerebral Vein (of Galen), Basal Vein (of Rosenthal), Inferior Anastomotic Vein (of Labbe), transverse vein, Middle Cerebral Veins (of Sylvius)- Deep and Superficial, Anterior cerebral vein,

Right transverse sinus is usually dominant and typically receives superficial blood- via continuation of SSS; left TS typically drains deep brain 


Venous Sinuses

NB inferior petrosal sinus sampling (to measure ATCH levels) is a clue that this drains pituitary.

Veins are located in subarachnoid space and divided into superficial and deep systems. 

Superficial Veins

Trolard, Labbe and Sylvius (superficial) all meet up.
