Some synonyms for this term include Galen's vein and the torcular Herophili, both of which are old medical terms for this structure. Other synonyms for Sinus Transversus include the transverse venous sinus, lateral sinus, and lateral cerebral sinus. This vein is an important component of the venous drainage system of the brain and can become obstructed or develop thrombosis, which can result in serious medical conditions such as intracranial hypertension or stroke.
