<prompt> The Vein of Galen drains intoSigmoid sinusStraight sinusTransverse sinusBasal vein  <response>: Ans. b Straight sinus. Ref. BD Chaurasia, Anatomy, 3rd ed., Vol III 303Great Cerebral Vein Of Galen Single median vein formed by union of two internal cerebral veins. Terminates into straight sinus. Its tributaries include the basilic vein, veins from pineal body, colliculi, cerebellum and adjoining occipital lobes. Vein of Galen malformation is one of the most common cause of congestive cardiac failure in neonates. The dural venous sinuses receive cerebral veins from the brain and drain the venous blood mainly into the IJV.Dural venous sinusesSuperior sagittal sinus It drains into the concluence of the sinuses Torcular.Inferior sagittal sinus It is located in the midsagittal plane, near the inferior margin of the falx cerebri. It terminates by joining with the great cerebral vein of Galen to form the straight sinus at the junction of the falx cerebri and tentorium cerebelli.Straight sinus It is formed by the union of the inferior sagittal sinus and the great cerebral vein. It usually terminates by draining into the confluence of sinuses or in transverse sinus.Occipital sinus It is found in the attached border of the tentorium cerebelli. It drains into the confluence of sinuses.Confluence of sinuses torcular herophili It is formed by the union of the superior sagittal, straight, and occipital sinuses. It drains into the two transverse sinuses.Transverse sinuses Lateral sinuses It drains venous blood from the confluence of sinuses into the sigmoid sinuses. Each sigmoid sinus joins with an inferior petrosal sinus to drain into the internal jugular vein below the jugular foramen. Thrombosed in complicated chronic mastoiditis DELTA SIGN on CT.
