Corpus: Superior thalamostriate vein

The superior thalamostriate vein, also called terminal vein, is a paired vein of the deep cerebral venous system (profunda cerebri veins). Together with the septate pellucid vein and the choroid vein, it forms the internal cerebral vein at the interventricular foramen (Foramen Monroi).

The superior thalamostriate vein runs subependymal on the stria terminalis between the thalamus and caudate nucleus in a rostral direction to the interventricular foramen. It is covered by the lamina affixa. From here it reaches the roof of the third ventricle (ventriculus tertius) where it flows into the internal cerebral vein. In the top view, the vein marks the border between the diencephalon and telencephalon.

Venous blood is drained from the pars centralis and the cornu frontale of the lateral ventricle, the genu corporis callosi, the caudate nucleus, the septum pellucidum, the parietal and occipital lobes and the frontal lobe.

In immature premature babies, perinatal asphyxia can lead to so-called terminalis haemorrhage.
