Arteriovenous Malformations (AVMs) in Children
An arteriovenous malformation (AVM) is an abnormal tangle of arteries and veins that disrupts normal blood flow and oxygen delivery. Although AVMs can occur anywhere in the body, those affecting the brain or spinal cord are the most serious, especially in children. Without timely diagnosis and treatment, an AVM can increase the risk of bleeding, stroke, seizures, and neurological complications that may impact a child’s growth and development.
At advanced neurosurgery associates nj our experienced pediatric neurosurgeon team provides comprehensive evaluation and advanced treatment for arteriovenous malformations in children across our New Jersey locations. Using state-of-the-art diagnostic imaging and minimally invasive and microsurgical techniques when appropriate, we create personalized treatment plans based on each child’s age, symptoms, and the size and location of the AVM. Families throughout New Jersey trust our specialists for compassionate, evidence-based pediatric neurosurgical care focused on achieving the best possible outcomes while protecting the developing brain and spinal cord.
What Is a Brain or Spinal Arteriovenous Malformation (AVM)?
A brain or spinal arteriovenous malformation (AVM) is a rare condition in which abnormal blood vessels connect arteries directly to veins without the normal capillaries between them. This causes high-pressure blood flow that can weaken blood vessels and increase the risk of bleeding, stroke, seizures, headaches, or nerve damage.
Most AVMs are present at birth but may not cause symptoms until later in life. At Advanced Neurosurgery Associates, our experienced pediatric neurosurgeon and neurosurgeons in New Jersey, along with our New Jersey spine surgeon team, provide advanced diagnosis and personalized treatment to help patients achieve the best possible outcomes.
Why AVMs Are Particularly Concerning in Children
Children with a brain or spinal arteriovenous malformation (AVM) have a higher lifetime risk of complications because the condition is present from birth. Early diagnosis and treatment by an experienced pediatric neurosurgeon can help prevent serious neurological damage and improve long-term outcomes.
- Higher Lifetime Risk: Children live with an AVM for many years, increasing their overall lifetime risk of bleeding.
- Annual Bleeding Risk: An untreated AVM has an estimated 2% to 4% chance of bleeding each year.
- Serious Complications: Bleeding can cause a stroke, seizures, weakness, vision problems, or permanent brain and spinal cord damage.
- Early Expert Evaluation: Prompt assessment by neurosurgeons in New Jersey helps determine the safest and most effective treatment plan.
- Advanced Multidisciplinary Care: At Advanced Neurosurgery Associates, our pediatric neurosurgeon, New Jersey spine surgeon, and spine surgeon New Jersey specialists work together to provide personalized care for children with brain and spinal AVMs.
- Why Treatment Is Recommended: Because of the lifelong risk of hemorrhage, most pediatric neurosurgeons recommend treating AVMs whenever it can be done safely instead of monitoring the condition alone.

For this reason, most pediatric neurosurgeons recommend active treatment of AVMs in children whenever it is safely achievable, rather than watchful waiting.

Symptoms of AVMs in Children
Arteriovenous malformation symptoms may be silent for years, or they may produce a range of symptoms depending on their size, location, and whether bleeding has occurred. Parents and caregivers should be aware of the following signs:
- Sudden, severe headache — often described as “the worst headache of my life”
- Seizures, which may be the first presenting symptom
- Weakness, numbness, or paralysis on one side of the body
- Vision problems, including double vision or loss of peripheral vision
- Difficulty speaking or understanding language
- Coordination problems or difficulty walking
- In infants, signs of increased intracranial pressure such as bulging fontanelle or rapid head growth
Diagnosis
Diagnosing an AVM involves a combination of advanced neuroimaging studies. The evaluation typically includes:
MRI (Magnetic Resonance Imaging)
Provides detailed views of brain tissue and can identify the location and size of the AVM, as well as any evidence of prior bleeding.
MRA (Magnetic Resonance Angiography)
Visualizes blood vessel structure and helps map the AVM’s relationship
to surrounding brain structures.
Cerebral Angiography (DSA)
Considered the gold standard for AVM diagnosis, this minimally invasive procedure uses contrast dye to produce a precise map of blood flow through the malformation. It is essential for surgical planning and grading the AVM’s complexity.
Our team works closely with pediatric neuroradiology specialists to ensure every child receives a thorough and accurate diagnostic workup before any treatment decisions are made.
Treatment Options
Arteriovenous malformation treatment for pediatric is highly individualized and depends on the AVM’s size, location, depth, and whether it has bled. The three primary treatment approaches, which may be used alone or in combination, are
Microsurgical Resection
Open brain surgery to physically remove the AVM is often the preferred approach for accessible lesions, particularly those that have already bled. When complete resection is achieved, the child is considered cured of the AVM. Our neurosurgeons use intraoperative imaging and neurophysiological monitoring to maximize safety and precision.
Stereotactic Radiosurgery
This non-invasive treatment uses focused beams of radiation to gradually obliterate the AVM over a period of two to three years. It is best suited for small, deep AVMs that are difficult to reach surgically.
Endovascular Embolization
A catheter-based procedure in which a physician navigates through blood vessels to inject material that blocks blood flow into the AVM. Embolization is frequently used as a preparatory step before surgery or radiosurgery to reduce bleeding risk and make the procedure safer.
Every treatment plan at Advanced Neurosurgery Associates is developed collaboratively, reviewed by our full clinical team, and discussed thoroughly with the child’s family before moving forward.

Frequently Asked Questions
What is an arteriovenous malformation in children?
An arteriovenous malformation (AVM) in children is an abnormal connection between arteries and veins that disrupts normal blood flow. These vascular abnormalities can occur in the brain, spine, or other parts of the body.
What are the common arteriovenous malformation causes?
The exact causes of arteriovenous malformations are not fully understood, but most AVMs are believed to develop before birth due to abnormal blood vessel formation during fetal development.
What are the symptoms of brain arteriovenous malformations in children?
Brain arteriovenous malformations in children may cause headaches, seizures, weakness, developmental delays, balance problems, vision changes, or sudden bleeding in the brain.
Are brain arteriovenous malformations in children dangerous?
Yes, untreated brain arteriovenous malformations in children can increase the risk of bleeding, stroke, or neurological complications. Early diagnosis and treatment are important for long-term health.
How are arteriovenous malformations diagnosed in children?
Doctors diagnose AVMs in children using MRI scans, CT scans, angiography, and other advanced imaging tests to evaluate abnormal blood vessels and blood flow.
What treatment options are available for arteriovenous malformation in children?
Treatment options may include embolization, microsurgery, radiosurgery, or careful monitoring depending on the child’s symptoms, AVM size, and location.
Where can families find arteriovenous malformation treatment in New Jersey?
Who are arteriovenous malformation specialists?
Yes, patients can find experienced Chiari malformation doctors near Rutherford, NJ at Advanced Neurosurgery Associates for expert diagnosis, treatment, and ongoing neurological care.
Why is early treatment important for children with AVMs?
Early treatment can help reduce the risk of bleeding, neurological damage, and developmental complications associated with arteriovenous malformations in children.
