The majority of these veins terminally drain through either the SVVs or the basal vein of Rosenthal (BVR) prior to reaching the VoG. 8.25. Anatomy. 4.9. Vein of Galen malformation ultrasound. Subependymal regions of the central nervous system drain venous blood into the inferior sagittal sinus superiorly or into the great cerebral vein of Galen inferiorly, both of which drain into the straight sinus. This article will discuss the anatomy and function of the great cerebral vein. Medial geniculate body. It affects the “great cerebral vein,” also known as the vein of Galen, which is one of the large veins that returns blood from the brain to the heart. 4.10A and B). The main venous channels draining internal structures of the hemisphere are the internal cerebral veins (Figs. The deficits experienced by the patient may reflect the general location of the venous thrombosis. Blood in the posterior fossa in part drains into the occipital sinus, which empties into the torcular. Gross anatomy. The superficial portion of the cerebrum is drained by the superficial, bridging cerebral veins, which empty into the superior sagittal sinus. These vessels connect with the straight and transverse sinuses via the medial and lateral collicular veins, respectively, and also with the superior petrosal sinus, through several small channels. [1] Most of the blood in the deep cerebral veins collects into the great cerebral vein. It is found in association with the stria terminalis and drains the caudate nucleus (via the transverse caudate veins) and internal regions of the hemisphere dorsal and lateral to the caudate nucleus. 23). Contact us. Information. It … They travel posteriorly in the roof of the third ventricle, enter the quadrigeminal plate cistern, and empty into the great cerebral vein of Galen. On the other hand, cerebral venous thrombosis may occur after brain surgery, meningitis, sinus infections, traumatic head injuries, or gunshot injury to the head, especially those that may involve the sinuses. The main function of the vein of Galen is to drain blood from the superior cerebellum, interpeduncular fossa, inferior horn of the lateral ventricle, parahippocampal gyrus, corpus callosum, midbrain, and choroid plexuses of the third and lateral ventricles. Rather than a true confluence, the superior sagittal sinus usually drains into the right transverse sinus and the straight sinus into the left. Prenatal diagnoses of the latter confirming true vein of Galen malformations further support their distinction from AVMs, for which in utero findings are yet missing.10,11 Consequently, vein of Galen malformations become clinically manifest in neonates with cardiac failure due to high intracranial shunt flow, whereas infants present with macrocephaly or neurologic symptoms.9 Vein of Galen malformations are usually not detected at later stages of life. The tentorial draining group consists of veins draining to the straight sinus, TSs, directly to the TH, or indirectly to the torcula via the tentorial sinuses. (1999). Medical definition of great cerebral vein: a broad unpaired vein formed by the junction of Galen's veins and uniting with the inferior sagittal sinus to form the straight sinus. It is frequently associated with severe consequences. Chaynes P(1). 4.11. When sinuses are involved (dural sinus thrombosis), the clots are most commonly found in the transverse sinus or in the superior sagittal sinus (Fig. It was only in 1986 that Raybaud and Strother8 described the dilated midline vein as the embryologic precursor of the vein of Galen, the median vein of the prosencephalon.

Jana Vasković Great cerebral vein (Vena magna cerebri) The great cerebral vein (vein of Galen) is a deep cerebral vein formed by the basal veins of Rosenthal, the internal cerebral and some superior cerebellar veins. The basal vein (of Rosenthal) begins on the orbital cortex as the anterior cerebral vein and in the sylvian fissure as the deep middle cerebral vein and proceeds around the medial edge of the temporal lobe to join the straight sinus. Reading time: 3 minutes.
