Cerebral venous thrombosis is a rare and serious cerebrovascular disease. There are many causes of cerebral venous thrombosis, in which in some cases the cause cannot be identified.
1. What is cerebral venous thrombosis?
In the body, the cerebral vein is an important vein, carrying out the task of transporting blood from the brain to the heart. Cerebral venous thrombosis is a condition in which the cerebral veins and the cerebral venous sinuses are damaged by the formation of a blood clot, also known as a thrombus.
Cerebral venous thrombosis can cause blockage and pooling of blood in the cerebral veins and lead to cerebral hemorrhage, swelling of the brain and possibly a stroke. Therefore, the disease needs to be diagnosed and detected in time to avoid life-threatening complications.

2. Common causes of cerebral venous thrombosis
Usually, blood vessel thrombosis is caused by atherosclerosis. However, for cerebral venous thrombosis, atherosclerosis is not the cause of this condition. To date, the cause of cerebral venous thrombosis has not been precisely determined.
Some studies show that the causes of cerebral venous thrombosis are classified into two types as infectious and non-infectious, specifically:
Cerebral venous thrombosis due to infection: Meningitis, mastoiditis, Ear infections leading to mastoid sinus infections, ear infections, and orbital infections are common causes of blood clots in the cerebral veins. Non-infectious cerebral venous thrombosis: Coagulation disorders such as inherited or acquired Thrombophilia, or myeloproliferative disorders, cancer, dehydration, oral contraceptive use, .. . is the cause of thrombosis in the cerebral veins. Different from the common stroke in the elderly (due to atherosclerosis, diabetes, hypertension, ...), cerebral venous thrombosis is common in young women due to pregnancy, collagen disease, perinatal period. In addition, due to other causes such as head trauma accidents, lumbar puncture surgery can also leave complications of blood clots in the cerebral veins.
