The septal veins, also called the anterior septal veins and the veins of the septum pellucidum, are

veins Veins () are blood vessels in the circulatory system of humans and most other animals that carry blood towards the heart. Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are those of the pulmonary and fetal c ...

of the cerebral venous system which drain blood from the

septum pellucidum The septum pellucidum (Latin for "translucent wall") is a thin, triangular, vertical double membrane separating the anterior horns of the left and right lateral ventricles of the brain. It runs as a sheet from the corpus callosum down to the f ...

of the anterior

frontal lobe The frontal lobe is the largest of the four major lobes of the brain in mammals, and is located at the front of each cerebral hemisphere (in front of the parietal lobe and the temporal lobe). It is parted from the parietal lobe by a Sulcus (neur ...

. The septal veins unify with the

superior thalamostriate vein The superior thalamostriate vein or terminal vein commences in the groove between the corpus striatum and thalamus, receives numerous veins from both of these parts, and unites behind the crus of the fornix with the superior choroid vein to form ...

and the superior choroidal vein at the interventricular foramina to form the

internal cerebral veins The internal cerebral veins are two veins included in the group of deep cerebral veins that drain the deep parts of the hemispheres; each internal cerebral vein is formed near the interventricular foramina by the union of the superior thalamos ...

Structure

The septal veins drain blood from the septum pellucidum bilaterally and terminate at the

venous angle The venous angle (also known as Pirogoff's angle and in Latin as ''angulus venosus'') is the junction where the ipsilateral internal jugular vein and subclavian vein unite to form the ipsilateral brachiocephalic vein. The thoracic duct drains at t ...

formed with the thalamostriate veins. Research by Jonathan Roth ''et al.'', 2010, has shown that the septal veins are often asymmetrical. The positions of the septal veins vary in relation to the interventricular foramina and the internal cerebral veins.

Clinical significance

Deep cerebral vein thrombosis is a rare condition characterized by the presence of a

blood clot A thrombus ( thrombi) is a solid or semisolid aggregate from constituents of the blood (platelets, fibrin, red blood cells, white blood cells) within the circulatory system during life. A blood clot is the final product of the blood coagulatio ...

in the deep cerebral veins and can appear in the septal veins. This condition is commonly comorbid with other thrombi in the cerebral veins.
