Cerebral Venous Sinus Thrombosis

Cerebral venous sinus thrombosis (CVST) is a rare type of stroke indicated by the formation of blood clots within the dural venous sinuses. These are large venous conduits that are situated between the 2 layers of the dura mater which are responsible for draining blood from the brain and returning it to the systemic circulation. Cortical venous thrombosis refers to the blockage of veins on the brain's cortical surface. Cerebral venous thrombosis encompasses both dural and cortical vein occlusions.
