Common Questions About Cerebral Venous Thrombosis (CVT)

How Common is Cerebral Venous Thrombosis?

No, Cerebral Venous Thrombosis is not common. Who does cerebral venous thrombosis effect? Only about 5 in one million people have this condition, so if you have CVST, it's incredibly rare. Cerebral venous thrombosis is more common in patients with underlying genetic clotting disorders and there's a recent association with post covid infections.

Cerebral Venous Thrombosis Causes

Cerebral Venous Sinus Thrombosis is a unique kind of stroke, that affects a small amount of people every year. Its causes are diverse.

The exact cause of CVT is often multifactorial, with several risk factors contributing to its development.

These may include genetic predisposition, certain medical conditions (such as thrombophilia), hormonal changes (such as pregnancy or the use of oral contraceptives), infections, head injuries, or the presence of a brain tumor.

Cerebral Venous Thrombosis Symptoms

There are many symptoms to watch out for, that might be a sign that you have CVST. They can vary depending on the affected veins and the extent of the clot. Here are some common signs and symptoms:

• Headaches (often described as thunrderclap headache)
• Blurred vision
• Difficulty speaking or understanding speech
• Fainting or loss of consciousness
• Loss of control over movement in a certain part of the body
• Weakness or paralysis of limbs
• Seizures
• Coma or changes in mental state

Some individuals may also experience symptoms related to increased intracranial pressure such as nausea, vomiting, and papilledema (swelling of the optic disc).

Clinical Presentation of Cerebral Venous Thrombosis

The way CVST presents varies. Over eighty percent of people with the condition experience headaches. Over forty percent of the people with the condition experience seizures, and about forty percent of the people with the condition experience hemiparesis (weakness in part of the body). Finally, about 15-20% of people with the condition have altered consciousness.

They can present with the following :

• Severe headaches
• Focal neurological deficits
• Altered conscious state
• Coma (depending on the location and extent of clot associated with brain damage)

Cerebral Venous Thrombosis Diagnosis and Management

To get diagnosed with CVST, you're going to need to get various imaging studies done, to confirm you're someone with the disease. Oftentimes, accurate MRIs or MRVs are performed. Diagnosis of CVT usually involves a combination of imaging studies, such as a magnetic resonance imaging (MRI) scan, along with blood tests to evaluate clotting factors and rule out other potential causes.

Managing the disease depends on your specific case, so it's always crucial to consult with a healthcare professional. Depending on your symptoms and case, you'll be able to figure out a treatment plan that works for you.

Cerebral Venous Thrombosis Complications and Risk Factors

As with all things, you might experience complications if you have CVST. For example, it is possible to have impaired speech, long-term brain injuries, developmental issues, vision and mobility issues, and more, if you have CVST.

Certain risk factors heighten your chance of contracting CVST. For example, you're more likely to get CVST if you have the following:

• Anemia
• Heart disease
• Iron deficiency
• Certain infections (head and neck region)
• Head injury (impacting the venous structures)
• Malignancies
• Inflammatory diseases
• Pregnancy and postpartum period
• Oral contraceptives

Apart from your genetic predisposition and certain medical conditions (clotting disorders or autoimmune diseases), pregnancy and postpartum period are risk factors.

Your risk of contracting CVST gets higher if you're pregnant, because many people with CVST contract the disease after giving birth. This is relevant, especially because many people with CVST are newborns, who contract the disease early on in life.

If you use oral contraceptives such as estrogen this can be a risk factor as well. More recently, there is a reported association with vaccination.

Cerebral Venous Thrombosis Treatments

The good news is, there are plenty of treatment options available for patients with CVST. There are neurointerventional treatments that can help people with CVST.

Treatment for CVT usually involves a combination of medications and, in some cases, procedures to remove or dissolve the clot. Anticoagulant medications, such as heparin and warfarin, are often prescribed to prevent the growth of the clot and promote its dissolution.

In more severe cases, endovascular procedures or surgery may be necessary to remove the clot or restore normal blood flow. These involve catherer based techniques to remove blood clots from the brain with severe life threatening clinical presentation and not responding to medical therapy.

When to Consider a Cerebral Venous Thrombosis Specialist Assessment in Singapore

Cerebral venous thrombosis is a complex neurovascular condition requiring careful evaluation of the cause, extent of clot formation and appropriate treatment approach.

Consider seeking specialist assessment if you:

• Have been diagnosed with cerebral venous thrombosis through CT, MRI or venous imaging.
• Experience persistent or worsening headaches with abnormal brain imaging findings.
• Have neurological symptoms such as weakness, numbness, seizures or speech difficulties.
• Have been diagnosed with a blood clot affecting the brain’s veins.
• Have risk factors for blood clot formation and new neurological symptoms.
• Require advice regarding treatment options or long-term follow-up.
• Want a second opinion regarding your CVT diagnosis or management plan.

At the Supreme Vascular and Interventional Clinic, cerebral venous thrombosis assessment focuses on understanding the underlying vascular problem through detailed brain and blood vessel imaging. Your specialist will review the location of the clot, associated risks and appropriate treatment options, including medical management and minimally invasive approaches where suitable.

Seek emergency medical attention immediately if you experience sudden neurological symptoms, seizures, loss of consciousness, sudden weakness, difficulty speaking or a severe worsening headache, as these may indicate a serious brain circulation problem.
