Septal veins

Septal Veins

The Septal Veins are a group of veins located within the brain, specifically within the cerebral hemispheres. They are responsible for draining blood from the septum pellucidum and the septum verum, two thin membranes that separate the lateral ventricles of the brain.

Anatomy

The septal veins are part of the cerebral venous system. They are located in the septum pellucidum, a thin, transparent partition between the lateral ventricles of the brain. The septal veins drain into the Superior Sagittal Sinus, a dural venous sinus located in the midline of the brain.

The septal veins are categorized into two types: the anterior septal veins and the posterior septal veins. The anterior septal veins drain the anterior part of the septum pellucidum, while the posterior septal veins drain the posterior part.

Function

The primary function of the septal veins is to drain deoxygenated blood from the septum pellucidum and the septum verum. This blood is then returned to the systemic circulation via the superior sagittal sinus and the Internal Jugular Vein.

Clinical Significance

Abnormalities or damage to the septal veins can lead to various medical conditions. For instance, thrombosis (clotting) in the septal veins can cause Cerebral Venous Sinus Thrombosis, a rare form of stroke. Additionally, malformations or aneurysms in the septal veins can lead to Cerebral Hemorrhage or Subarachnoid Hemorrhage.
