The Vein of Galen

The vein of Galen is a vital deep vein in the brain that helps drain blood from the brain's internal structures. It is part of the brain's venous system, collecting blood from areas like the deep veins and directing it toward larger veins that carry blood back to the heart. In some cases, there can be a congenital abnormality called a vein of Galen malformation, where this vein develops abnormally, leading to potential issues such as increased blood flow and pressure, which may require medical intervention.
