The application of some hemostatic drugs in promoting blood clotting at the same time will also increase the risk of intracranial thrombosis, such as tranexamic acid and so on. In addition, the long-term use of contraceptives by some women leads to an increase in the levels of estrogen and progesterone, resulting in a decrease in anticoagulant proteins will also promote the formation of intracranial thrombosis.
