What if a single procedure could save you from a lifetime of seizures, headaches, and uncertainty? Discover the power of Transvenous Root Embolization : an innovative treatment for AVM. 

What is an Arteriovenous Malformation (AVM)?

An AVM is an abnormal tangle of blood vessels in the brain. It is  a condition where arteries directly connect to veins, bypassing the capillary network . AVMs can cause tissue and brain damage. 

What Causes AVM?

The exact cause of AVM is still unknown. However, it's believed to be:

  •  Hereditary, developing during fetal development

  •  Caused by genetic mutations

  •  Triggered by problems with chemicals that stimulate blood vessel growth

  •  Resulting from injury to the central nervous system

What are the Symptoms of AVM?

Symptoms may not appear until the AVM ruptures. Common symptoms include:

  •  Headache

  •  Dizziness

  • Muscle weakness

  • Partial or complete paralysis

  • Tingling sensation

  •  Numbness

  • Nausea and vomiting

  • Seizures

  • Mental confusion

  • Hallucinations

  • Dementia

  • Shortness of breath

  • Swelling and pain

What is the Conventional Treatment for AVM?

The conventional treatment is a craniotomy, an open skull surgery. It is a surgical procedure that removes a piece of skull to treat an arteriovenous malformation. This method is only possible if the patient is in good health, and the AVM is accessible.

What are the Risks of Craniotomy?

Risks include:

  • Swelling

  • Infection

  • Bleeding

  • Damage to nearby healthy tissues

What is Transvenous Root Embolization?

Transvenous Root Embolization is a minimally invasive procedure that blocks abnormal blood vessels in the brain. This treatment reduces blood flow to the problematic area, preventing further complications.

How is Transvenous Root Embolization Performed?

The procedure involves:

  • Inserting a catheter through a vein and advancing it to the target area

  • Using an embolic agent to block the vein

  • Injecting coils, gel foam, or liquid to block the abnormal veins

What are the Benefits of Transvenous Root Embolization?

Benefits include:

  • Minimally invasive

  • Less recovery time

  • Lower risk of complications

  • High success rate

AVM Treatment: Myth busters

Q:   Is AVM hereditary ?

A:  While a genetic predisposition might exist, most AVMs are not directly inherited from parents. 

Q:   Is immediate surgery needed for all AVM cases ?

A:    Not all AVMs require immediate surgery, as the decision to treat depends on factors like size, location, and risk of rupture. 

Q:   AVM only affects the brain ?

A: While most commonly found in the brain, AVMs can occur in other parts of the body like the spinal cord or limbs.
