cerebral venous anatomy

Question 1

name three major sources of outflow from intracranial/intraspinal compartments

Answer 1

1. (right usually dominant) internal jugular vein
2. orbital veins
3. venous plexuses around the vertebral arteries

Question 2

Trace the venous flow back from internal jugular vein!

Answer 2

1.Inferior petrosal sinus near junction with
2. Sigmoid sinus
3. Transverse sinus (right= dominant)
——–vein of Labbe (inferior anastomotic vein)
Confluence of Sinus - torcular Herophili
1. Occipital Sinus
2. Superior Sagittal Sinus
———vein of Trolard (superior anastomotic vein)
3. Straight Sinus
——1. Inferior Sagittal Sinus
——2. Vein of Galen (THE GREAT cerebral vein)
—————-flow into Vein of Galen – see separate q.

Question 3

What veins empty into great vein of Galen?

Answer 3

• Basal cerebral vein (of Rosenthal) into which insular veins empty.
• Posterior septal veins
• internal cerebral vein into which thalamostriate vein (incl transverse caudate veins) and anterior septal vein empty
