Deep cerebral veins

  • The deep cerebral veins (latin: venae cerebri profundae) are venous blood vessels that collect blood from the white matter, basal ganglia and from the choroid plexuses.

    In the human brain, there are four paired and one unpaired deep cerebral vein. Vessels belonging to the deep cerebral veins include the following:

    • thalamostriate vein,
    • choroid vein,
    • vein of the septum pellucidum,
    • internal cerebral vein,
    • great cerebral vein.

    The thalamostriate vein passes between the superior surface of the thalamus and the caudate nucleus and collects venous blood from the thalamus, caudate nucleus and the internal capsule. Upon reaching the interventricular foramen, the thalamostriate vein units with the choroid vein and the vein of the septum pellucidum to form the internal cerebral vein.  

    The choroid vein collects venous blood from the choroid plexus of the lateral ventricle.

    The vein of the septum pellucidum collects venous blood from the surfaces of the anterior horn of the lateral ventricle.

    The internal cerebral vein is a paired vessel that is formed by the union of the thalamostriate, choroid veins and the vein of the septum pellucidum. The internal cerebral vein passes posteriorly along the superior surface of the third ventricle. Further, it runs between the layers of the tela choroidea of the third ventricle. Below the splenium of the corpus callosum the two internal cerebral veins unite and form the great cerebral vein.

    The great cerebral vein is a large, unpaired blood vessel that passes posterosuperiorly around the posterior border of the splenium of the corpus callosum and drain into the straight sinus. The great cerebral vein receives the basal vein that collects venous blood from the hypothalamus and the basal nuclei.
