Cerebral Venous Sinus Thrombosis

Make Appointments & Get Care

What is Cerebral Venous Sinus Thrombosis?

Cerebral venous sinus thrombosis (CVST) is a rare form of stroke that can occur in adults and children. A blood clot forms in the brain’s venous sinuses, which then prevents blood from draining out of the brain. This causes pressure to build in the blood vessels and can lead to swelling and bleeding in the brain.

What Are the Symptoms of Cerebral Venous Sinus Thrombosis?

Symptoms can vary based on where the blood clot forms, but may include:

  • Severe headache
  • Nausea and vomiting
  • Weakness or numbness in your face, arm, or leg, especially on one side of the body
  • Difficulty seeing, talking, or understanding
  • Difficulty with balance or walking
  • Dizziness or loss of coordination 
  • Loss of consciousness

What Causes Cerebral Venous Sinus Thrombosis?

Sometimes the cause is not clear, but CVST can be caused by:

  • Medications that contain estrogen
  • Elevated levels of estrogen in pregnancy and post-pregnancy
  • Tamoxifen and chemotherapy drugs
  • Cancer
  • Clotting disorders (inherited and acquired)
