Cerebrovascular Anatomy – Venous
- All named veins are in italics
- Superior sagittal sinus – usually drains right
- Superior anastemotic vein (of Trolard) connects to
Sylvian fissure
- Inferior sagittal sinus – usually drains left
- Deep veins
- Internal cerebral vein – from tela choroidea of 3rd
ventricle (velum interpositum) over thalamus posterior to quadrigeminal
cistern, join to form vein of Galen
- Formed from thalamostriate and septal veins
(venous angle), also choroidal, epithalamic, and lateral ventricular
- Vein of Rosenthal – from inferior and medial temporal lobes,
travel posterosuperiorly through ambient cistern, joins internal cerebral
vein to become vein of Galen
- Vein of Galen – internal cerebral + vein of Rosenthal, also from
occipital and posterior callosal; travels under splenium to merge with
inferior sagittal sinus to form straight sinus
- Straight sinus
- Transverse sinus
- Inferior anastemotic vein (of Labbe) connects to Sylvian
fissure
- Sigmoid sinus
- Cavernous sinus
- Superior petrosal vein – to transverse/sigmoid
junction
- Inferior petrosal vein – to jugular bulb
- Pterygoid plexus
- Pharyngeal plexus
