Once it is confirmed that the child’s symptoms stem from a blood clot, medications such as intravenous heparin and/or aspirin are used to prevent the clot from growing and give the body the chance to break the clot down. It may be necessary to keep taking these medications (or related medications, such as Coumadin [warfarin]) for several months.

If a child is critically ill and medications are not enough to clear the blood clot, physicians in Boston Children’s Cerebrovascular Surgery and Interventions Program sometimes perform endovascular thrombolysis. This emergency treatment, performed under general anesthesia during a cerebral angiogram, guides a very small catheter into the cerebral venous sinus (a main channel in the skull that collects venous blood) to introduce balloons, suction devices or other tools to break up the clot or even extract it from the vessel. In some cases, clot-dissolving drugs such as tissue plasminogen activator (tPA) are delivered through the catheter, right at the blockage.

Once any immediate danger has passed, we closely monitor all children to prevent potential complications of the venous thrombosis, such as hydrocephalus (“water on the brain”), excessive venous pressure in the brain and seizures.

We are grateful to have been ranked #1 on U.S. News & World Report's list of the best children's hospitals in the nation for the third year in a row, an honor we could not have achieved without the patients and families who inspire us to do our very best for them. Thanks to you, Boston Children's is a place where we can write the greatest children's stories ever told.”
