Cerebral venous thrombosis is a blood clot of the brain’s cerebral vein, which is responsible for draining blood from the brain. If blood collects in this vein, it will begin to leak into the brain tissue and cause a hemorrhage or severe brain swelling.
When detected early, it can be treated without causing life-threatening complications.
A blood clot in a cerebral vein can cause pressure that leads to brain swelling. This pressure can cause headaches or damage brain tissue in more severe cases.
Symptoms may vary depending on where the blood clot occurs in the brain. However, more common symptoms can include:
If you are experiencing a more severe case of cerebral venous thrombosis, you may bear stroke-like symptoms. These may include:
If you begin experiencing any of these symptoms, head to an emergency ward immediately.
Other symptoms from severe thrombosis include:
Cerebral venous thrombosis occurs when blood clots form in the brain’s venous sinuses. Though it is an uncommon condition, it can be triggered by a number of factors.
Some of the most common risk factors include:
Less common risk factors of include pregnancy and other blood clotting disorders. Both conditions can make blood clot easily, affecting proper blood flow throughout the body and brain.
In infants, the most common cause of cerebral venous thrombosis is infection, specifically in the ear. The causes of some cerebral venous thrombosis cases are still unknown.
If left untreated, it can have life-threatening consequences.

When diagnosing cerebral venous thrombosis, doctors will evaluate the symptoms that you experience and enquire about your medical and family history. However, a proper diagnosis depends on the blood circulation in your brain, which the doctors may study using imaging tests to detect blood clots and swelling.
A doctor may misdiagnose a case of cerebral venous thrombosis if they use the wrong test.
The recommended imaging tests to help detect cerebral venous thrombosis are:
Cerebral venous thrombosis treatment options depend on the severity of the condition. Primary treatment recommendations focus on preventing or dissolving blood clots in the brain.
Medication
Doctors may prescribe anticoagulants or blood thinners to help prevent blood clotting and any further growth of the clot. The most commonly prescribed drug is heparin, which is injected directly into the veins or under the skin.
Once the doctor thinks you are stable, they may recommend an oral blood thinner (such as warfarin) as a periodic treatment. This can help prevent recurrent blood clots, especially if you experience blood clotting disorder.
Other than helping to prevent blood clots, the doctor would also address the symptoms of cerebral venous thrombosis. If you have experienced a seizure from this condition, the doctor would prescribe anti-seizure medication to help control seizures in the future. Similarly, if you begin to experience stroke-like symptoms, the doctor would give you advice on the best treatments available.
Monitoring
In all cases of cerebral venous thrombosis, the doctor would monitor brain activity. Other venograms and imaging tests may be recommended to assess thrombosis and ensure that there are no additional clots. Follow-ups are also crucial to ensure you do not develop clotting disorders, tumors or other complications from cerebral venous thrombosis. The doctor would perform additional blood tests to see if you have any clotting disorders.
Surgery
In more severe cases of cerebral venous thrombosis, the doctor may recommend surgery to remove the blood clot and fix the blood vessel. This procedure is referred to as thrombectomy.
