Basal vein

Basal Vein The basal vein (also known as Rosenthal's vein) is a significant blood vessel in the brain. It is responsible for draining blood from the brain's deep structures and is a crucial part of the cerebral venous system.

Structure

The basal vein begins near the anterior perforated substance, where it is formed by the union of several small veins. It runs backward along the medial border of the lentiform nucleus, and, in its course, receives tributaries from the frontal lobe, temporal lobe, insula, and internal capsule. It ends at the great cerebral vein.

Function

The basal vein drains blood from the deep structures of the brain, including the striatum, thalamus, and internal capsule. It plays a vital role in maintaining the brain's metabolic needs by ensuring the efficient removal of deoxygenated blood and waste products.

Clinical significance

Due to its location and the structures it drains, the basal vein can be involved in various neurological disorders. For instance, obstruction or damage to the basal vein can lead to venous infarction or hemorrhage.
