How AVM Embolisation Works: Procedure, Benefits, Risks, and Cost

What is an Arteriovenous Malformation (AVM)

The blood circulates through your body within an organized, closed circuit of blood vessels. There are 3 main components:

• Arteries: They carry blood (which is nutrient- and oxygen-rich) from the heart to your brain and finally to the rest of the body.
• Veins: They return blood (which is low in oxygen and nutrients) and waste by-products from the rest of the body back to your heart and lungs.
• Capillaries (the bridge between arteries & veins): The exchange of blood between arteries and veins takes place in your capillaries, which are the bridge where the smallest blood vessel units of arteries and veins connect.

Now, in an arteriovenous malformation (AVM), a bridge of capillaries is absent, causing an abnormal tangle of blood vessels that looks like a bird’s nest. This leads to a flow of high blood flow from the arteries to the veins that aren’t used to high blood flow/pressure. This can cause vessel rupture and bleeding into your brain, which can result in hemorrhage or stroke. That's why a doctor may suggest AVM embolization after a detailed diagnosis.

Normal Blood Supply	Abnormal Blood Supply in AVM
Blood flow from the Arteries ↓ Heart → Brain → Body ↓ Through Capillaries ↓ To Veins ↓ Normal Blood Pressure ↓ Good Circulation ↓ No Risk of Rupture or Stroke	Blood flow from the Arteries ↓ Capillary Bridge Missing ↓ Direct Flow from Arteries → Veins ↓ High Pressure in Veins ↓ Weak Vessel Walls ↓ Abnormal Blood Flow ↓ Risk of Rupture, Bleeding, or Stroke ↓ The doctor may suggest AVM embolization

What is AVM Embolization?

AVM embolization is a minimally invasive procedure. This helps address abnormal blood vessel tangles known as arteriovenous malformations (AVMs), lowering the risk of hemorrhage or stroke. 

How AVM Embolisation Works

A doctor inserts a thin tube into a blood vessel, generally in the groin, and guides it to the AVM using X-rays. Then, a special material like glue or coils is injected to block blood flow to the AVM. This helps prevent bleeding and helps reduce its size safely. It works by reducing the number of abnormal connections between blood vessels that occur in the brain.

AVM Embolization is Also Known as:

1. Endovascular Embolization
2. AVM Embolisation
3. Embolotherapy
4. Endovascular Therapy
5. Embolization Treatment (for AVMs)

What is the AVM Embolization Procedure? Step by Step

Your doctor may follow the general procedure for the maximum AVM embolization.

A. Before AVM Embolization Procedure

• Proper diagnosis is done using MRI, CT angiography, or cerebral angiogram to locate and study the AVM thoroughly.
• The doctor evaluates the symptoms, such as bleeding risk, and the AVM size and location.
• Then a decision is made if embolization is suitable for you or not.
• All the vitals will be checked through blood tests and a general physical examination. This will ensure your fitness for the procedure.
• The healthcare team explains the AVM embolization procedure and its risks and benefits.
• Finally, your consent will be taken.

B. During the AVM Embolization Procedure

• Anesthesia or sedation is administered.
• A thin, flexible tube (catheter) is inserted, generally in the groin artery.
• Using X-ray, this catheter is carefully guided or moved through blood vessels to reach the AVM in the brain.
• A special material (such as glue, coils, or a liquid embolic agent) is injected through the catheter. 
• This stops blood flow in abnormal vessels (or AVM).
• The catheter is removed after the blood flow is blocked in the targeted AVM part.
• The catheter insertion site is carefully closed and bandaged.

C. After AVM Embolization Procedure

• You will be closely monitored for one day.
• You may experience mild headaches, nausea, or temporary neurological symptoms. These will be evaluated closely.
• You will have to attend follow-up imaging tests (angiogram or MRI) to check how much of the AVM remains.
• Depending on the AVM complexity, multiple embolization sessions can be scheduled.
• Follow all your doctor’s advice and take prescribed medicine on time.
• You can resume regular activities gradually as per the doctor’s advice.
• Full recovery depends on individual factors and can take weeks to months.

When to Consult the Doctor?

Consult your doctor right away if you experience the following symptoms:

1. Sudden severe headache
2. Stroke-like symptoms such as weakness, numbness, vision, or speech trouble
3. Heavy bleeding or swelling at the catheter insertion site
4. Persistent nausea
5. Vomiting, dizziness, or confusion
6. Worsening neurological symptoms

What are the AVM Embolization Risks

The brain AVM embolization procedure is safe and effective if done under a reliable medical team, like at Eternal Hospital. However, like other medical procedures, it can come with less common risks like:

1. Air embolism (an air bubble that blocks a blood vessel).
2. Nerve damage (neuropathy).
3. Soft tissue necrosis (cell death in your body tissues).
4. Stroke or blindness if embolic agents in the head migrate.
5. Allergic reaction to the special material used in the procedures.
6. Bruising or bleeding incision.
7. Embolic agent misplacement/migration.
8. Life-threatening infections, including sepsis.

What are the Brain AVM Embolization Benefits

AVM embolization offers the following 5 benefits:

1. Decrease AVM Size

Embolization shrinks the abnormal blood vessel tangle. This helps make further treatments, such as surgery or radiosurgery, safe and less complex.​

2. Reduce Risk of Bleeding 

It safely blocks blood flow to the AVM. This helps prevent dangerous bleeding in the brain bleeds/hemorrhages.​

3. Minimally Invasive AVM Embolisation

The procedure is performed with the help of a thin tube. This helps avoid open brain surgery and a faster recovery time.​

4. Reduces Symptoms

It can relieve problems such as headaches, seizures, or neurological symptoms due to. This helps improve the quality of life.​

5. Shorter Hospital Stay

Most individuals go home faster with fewer complications as compared to conventional surgery. This helps return to normal life quickly.

What is the Recovery Time?

The recovery time after AVM Embolization depends on individual factors, szie if AVM and the complexity of the procedure. You may start to feel better after 1 week to 1 month. However, complete healing can take up to 6 months.

AVM Embolization Cost in India

The AVM Embolization Cost in India depends on the following factors:

1. Complexity of AVM
2. Hospital Choice
3. Experience of Doctor
4. Diagnostic Tests
5. Hospital Stay
6. Location
7. Materials used like embolization agents such as glue, coils, Onyx, and catheter
