cerebral dural venous sinus thrombosis (CVST)
adult prevalence is 3-16 cases per million population per year with 75% being female and mainly in young adults, presumably due to pregnancy and combined oral contraceptive pill (OCP)
being the prime causative factors
in children, annual prevalence is around 7 per million children, some 40% of these occur in neonates, mostly in dehydrated, unwell neonates
first recognized as a cause of death in 1825, but pre-mortum diagnosis on clinical grounds occurred in the 1940's, but only became radiologically possible with the advent of venography in 1951
the cerebral venous sinuses (aka dural venous sinuses) drain blood from the brain into the internal jugular veins and differ from normal veins in that their walls lack a full set of layers (there is no tunica media, and instead are dura mater lined with endothelial cells).
they do not have venous valves
