Cerebral Sinovenous Thrombosis in Children

What is cerebral sinovenous thrombosis?

Cerebral sinovenous thrombosis (CSVT) is a rare but serious condition that is a cause of stroke in children, and newborns. CSVT occurs when a blood clot (thrombus) blocks blood flow within the veins draining the brain. This can occur in the large veins surrounding the brain or in the veins that course through the brain. It can lead to increased blood pressure on the venous side of circulation in the brain, and in turn impair blood flow into the brain, causing an ischemic stroke.

In addition, CSVT can cause bleeding from veins in the brain and can cause a type of stroke known as a hemorrhagic venous stroke or infarction.

How we care for cerebral sinovenous thrombosis

Children who have experienced a stroke as the result of CSVT receive treatment from the team of experts in the Boston Children’s Hospital Stroke and Cerebrovascular Center. When surgery is necessary to remove a clot, we work with our colleagues in the Cerebrovascular Surgery and Interventions Center to coordinate seamless and state-of-the art care of children with CSVT.
