What is AVM embolisation?
What Is Embolization? Embolization is a method of plugging the blood vessels of the AVM. Under X-ray guidance, a small tube called a catheter is guided from the femoral artery in the leg up into the area to be treated. A neurological exam is performed before and after a small amount of medicine is injected.
How long does AVM embolization take?
The procedure takes about 30 minutes. Your doctor may prescribe medications to manage any pain and discomfort after the procedure.
Can spinal AVM be cured?

Does embolization cure AVM?
Sometimes, this is the only necessary treatment. However, embolization usually does not permanently destroy the AVM. It’s typically used to help reduce the AVM size and lower the risk of bleeding before radiosurgery or surgery to remove the AVM.
How is AVM on the spine treated?
There are three ways to remove the spinal AVM :
- Conventional surgery. In this procedure, a surgeon makes an incision to remove the AVM , taking care to avoid damaging the spinal cord and other surrounding areas.
- Endovascular embolization.
- Radiosurgery.
Are you awake during embolization?
You will be awake during the procedure. You will be given medicine to help you relax and to help with pain. The treatment usually takes 1 to 3 hours. You can likely go home 6 to 24 hours after the treatment.
What causes AVM in spine?
What is a spinal arteriovenous malformation? Arteriovenous malformations (AVMs) occur when the connections between the veins and arteries don’t form correctly and the vessels become entangled. Usually, these abnormalities develop in the fetus, or in a newborn baby. AVMs can occur anywhere in the body.
What is the life expectancy of someone with an AVM?

|---|---|
| Life Expectancy | Risk1 of Bleeding |
| 40 years | 80.3% |
| 50 years | 86.8% |
Is AVM embolization permanent?
The goal of curative embolization is the complete and permanent obliteration of the AVM nidus, with the restoration of normal arterial blood flow and the preservation of venous drainage.
How long does brain embolization last?
This procedure is usually completed in one to two hours; however, it may last up to several hours.
What is AVM embolization and how does it work?
What Is Embolization? Embolization is a method of plugging the blood vessels of the AVM.

A neurological exam is performed before and after a small amount of medicine is injected.
What is endovascular embolization of brain arteriovenous malformations?
Endovascular embolization of brain arteriovenous malformations (AVMs) is conventionally performed from a transarterial approach. Transarterial AVM embolization can be a standalone treatment or, more commonly, used as a neoadjuvant therapy prior to microsurgery or stereotactic radiosurgery.
What is an AVM in the brain?
AVM Embolization Arteriovenous malformations (AVMs) of the brain or spine refer to abnormal connections between arteries and veins. AVMs can be difficult or dangerous to treat and may cause bleeding into or around the brain, most commonly in young adults.
How do you get rid of an AVM?
Safe, surgical removal of AVMs or treatment with radiation may require partial or complete closure of the AVM through embolization (blocking) techniques. This preparation improves the safety, effectiveness and outcome of surgery. What Causes Arteriovenous Malformations?
