Embolization of AVM

An arteriovenous malformation (AVM) is a rare condition where arteries and veins form abnormal connections, bypassing the normal network of capillaries. Because blood flows directly from arteries to veins, pressure within these vessels increases, which may lead to complications such as bleeding in the brain or other parts of the body.

Embolization is a minimally invasive procedure used to treat AVMs. A small catheter is inserted through a blood vessel in the groin or arm and guided to the site of the malformation. Once in position, doctors inject special materials to block the abnormal vessels, reducing or stopping the flow of blood through them.

This treatment helps control bleeding, lowers the risk of future rupture, and improves overall blood circulation. Since embolization does not require large incisions, recovery is typically faster compared to open surgery.

Signs & Symptoms

 The symptoms of an AVM depend on its location and size. Common symptoms include:

  • Headaches: Severe or persistent headaches.

  • Seizures: Unexpected seizures or convulsions.

  • Neurological symptoms: Difficulty speaking, weakness, numbness, or vision problems.

  • Bleeding: In severe cases, sudden bleeding or stroke-like symptoms.

  • Pain: Localized pain in the affected area, depending on AVM location.

Note: Some people with AVMs might not have noticeable symptoms until a complication occurs.

Causes

 The exact cause of AVMs is not always clear, but they are believed to occur due to:

  • Genetic factors: Some AVMs may be inherited or caused by genetic mutations.

  • Developmental issues: AVMs can form during fetal development or early childhood.

  • Unknown causes: In many cases, the exact cause is unknown.

When to seek medical attention?

 Seek medical help if you experience:

  • Sudden severe headache: Especially if it's the worst headache you've ever had.

  • New or worsening neurological symptoms, Such as weakness, numbness, or speech difficulties.

  • Seizures: Unexplained seizures or convulsions.

  • Sudden vision changes: Loss of vision or blurred vision.

Diagnostics & Tests

 Doctors use various tests to diagnose AVMs:
Imaging tests:
MRI (Magnetic Resonance Imaging): This imaging technique provides detailed images of brain structures to detect AVMs.
CT Scan (Computed Tomography): Helps visualize AVMs and any associated bleeding.
Angiography: A specialized imaging test that uses contrast dye to highlight blood vessels, helping pinpoint the AVM's exact location and size.
Ultrasound is used in some cases to evaluate AVMs in other parts of the body.

Do’s & Don’ts

 Do's:

  • Follow medical advice: Adhere to your treatment plan and attend all follow-up appointments.

  • Take prescribed medications: Use any medications as directed to manage symptoms and prevent complications.

  • Rest and recover: Allow time for recovery after the procedure and avoid strenuous activities.

  • Report new symptoms: Notify your doctor if you experience new or worsening symptoms.

 Don'ts:

  • Avoid self-diagnosing: Always rely on medical professionals for accurate diagnosis and treatment.

  • Don't skip follow-up appointments: Regular check-ups are essential for monitoring progress and preventing issues.

Frequently Asked Questions For Embolization of AVM

Embolization is often effective, but its success depends on the size, location, and complexity of the AVM. Some cases may require additional treatments.

Risks include bleeding, infection, allergic reactions to contrast dye, and potential damage to surrounding tissues.

Recovery time varies, but most patients can resume normal activities within a few weeks. However, some individuals may require a more extended recovery period, depending on their specific circumstances.

While embolization can significantly reduce the risk of recurrence, residual or new AVMs may develop in some cases and require further treatment.

After treatment, maintaining a healthy lifestyle, including regular check-ups and avoiding activities that could strain the affected area, is essential for overall health and well-being.
