Causes of cerebral venous thrombosis

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.

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.

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.

Cerebral venous thrombosis is a rare disease, however, the following factors increase the risk of disease such as:
Women who abuse oral contraceptives or drugs that change the female hormone estrogen. Women who are pregnant or in the perinatal period, the postpartum period. Injury, head injury due to accident or surgery, treatment. Blood clotting disorders that block blood vessels, stagnate blood circulation, and change blood composition can increase the risk of cerebral venous thrombosis. Newborns have infections, especially ear infections. Adults with infections in the face, ears, sinuses, and throat. Cancer, tumor. Are overweight, obese or have a protein deficiency.

Cerebral venous thrombosis without typical clinical symptoms. Depending on the location of the blood clot, the symptoms will vary. Below are some common symptoms of brain vein thrombosis, which are classified as moderate to severe and severe:
Moderate: Blurred vision, nausea and vomiting, pain severe headache. Severe: Speech disorders such as slurred speech, hemiplegia, physical exhaustion, weakness and loss of consciousness. Severe: Restriction of movement in some parts of the body, convulsions, fainting, coma, even death. As soon as the serious manifestations of cerebral venous thrombosis are noticed, the patient should be taken to the emergency room immediately.
