" Dural sinus thrombosis can happen to anyone who has a tendency to form blood clots."
This is the Golden rule and as the brain is confined in skull and the sinuses are small spaces, initially it may accomodate a clot but finally there would be a thrombosis.
When a blood clots sits inside of one of the brain's sinuses, it causes a back up of blood inside the venous system of the brain, preventing blood from leaving the brain's tissues.
So these conditions you mentioned have likelihood to form more clots so there is more risk of Dural Sinus Thrombosis.
Take care and come back to us on further queries.
Thanks for your reply. I was just concerned about neurological problems to mother after giving birth.
