The most common forms of pediatric cerebrovascular disease (CVD) that we treat at the Cerebrovascular Surgery and Interventions Center are explained below. We also treat a variety of other conditions, including sinus pericranii and extracranial arteriovenous malformations/fistulas and perform intra-arterial chemotherapy for retinoblastoma and other tumors in children. If you are inquiring about a condition not listed below, please feel free to contact us.



A pediatric cerebral aneurysm forms when a weak segment of a vessel in the brain expands outward. Aneurysms can be discovered incidentally or after they cause bleeding in the brain. When we suspect that a child has an aneurysm that has burst. Read more.

Arterial dissection

Arterial Dissection 


An arterial dissection is a tear along the inside lining of an artery in the head or neck. Dissection of the vertebral or carotid artery in the head or neck, or spinal arterial dissection can cause serious neurologic problems, such as childhood stroke.

Arterial ischemic stroke


 A pediatric arterial ischemic stroke is an injury to the brain or spinal cord caused by obstruction of blood flow resulting from a clot, narrowed or damaged arteries, or both.

Arteriovenous fistulas (AVFs)


Dural or pial AVFs in children are a type of vascular abnormality in which arteries connect directly with veins, bypassing the capillaries. Depending on their location and the vessels involved, treatment may be required urgently, even if they are not causing symptoms.

Arteriovenous malformations (AVMs)



AVMs are tangles of arteries and veins that are abnormally connected and are usually present at birth. Most AVMs are discovered in children with hemorrhage, seizures and other neurological problems. Read more.

Cavernous malformations

Cavernous malformations

A pediatric cavernous malformation (also called a cavernoma) is a small, berry-like mass consisting of an abnormally expanded, thin-walled blood vessel. It can cause bleeding that poses a risk of seizures or potentially life-threatening pressure on the brain. Read more.

Cerebral venous thrombosis

Cerebral Venous Thrombosis


Venous thrombosis is the blockage of a vein or a large venous sinus (channel) by a blood clot. When this happens in the brain-specifically in the cerebral veins or the dural sinus-hemorrhage and stroke can occur.

Moyamoya disease program


In moyamoya disease, the walls of the internal carotid arteries and their major branches, supplying blood to key areas of the brain, become thickened and narrowed, posing a high risk of stroke. Boston Children's has pioneered a surgical procedure. Read more.

Vein of Galen malformations

vein of galen 


Vein of Galen malformations are a type of rare arteriovenous fistula (AVF) deep in the brain. They often become apparent at birth in newborns with heart failure. Read more.
