1
Today we're talking about arteriovenous malformations or AVM for short.
2
A lot of times people ask me, what is an AVM or an arteriovenous malformation?
3
And it's a very good question.
4
Arteriovenous malformations can be very complicated.
5
I'd like to draw an AVM for you so you can help understand this process.
6
An AVM is basically a tangle of very, very immature blood vessels in the brain.
7
in the brain.
8
It almost looks like a bird's nest, but very immature arteries.
9
There are many arteries that feed into an AVM, and typically there are very large veins that drain the AVM.
10
I'll label these to be clear.
11
These are veins and these are arteries.
12
The arteries or fire hoses is bring a lot of pressure and blood into the AVM.
13
And veins, as you remember, veins you have in your arm are very soft and weak.
14
And these veins don't like the amount of blood flow that comes through the AVM.
15
This AVM lives in the brain tissue.
16
And so it's a potential that all this blood going through the AVM can cause the AVM to break or bleed, which can cause very, very serious problems in the brain.
17
Approximately three to 4% of AVMs will rupture every year.
18
So neurosurgeons like to treat AVMs to prevent that from happening.
19
There are many different treatment strategies to treat an arteriovenous malformation into someone's brain and I'll quickly go through all those.
20
The first one and one of the most tried and true procedures is brain surgery to physically remove the AVM from the brain.
21
The way this is done is with a small incision on the scalp.
22
We remove some bone from the skull, which we put back later, and we physically remove the AVM.
23
An AVM is removed by coagulating or sacrificing arteries that feed the AVM to reduce the blood flow.
24
Then we coagulate and remove the veins, and we physically then take the AVM out of the brain.
25
This cures the AVM.
26
Now sometimes AVMs have so much blood flow that go into them that we need to slow that blood flow down before surgery.
27
This way we can accomplish by taking blood catheters up into our AVM and injecting various substances like glue or a material called onyx, which is like black toothpaste that can slow down the AVM.
28
These catheters are placed in the artery and then we simply inject that material in the AVM to slow the AVM down.
29
We don't think we can cure the AVM with that approach but it helps us to operate on the AVM because there's less blood flow.
30
The last option I'll discuss is something called gamma knife radiosurgery which is a form of radiation therapy that is very accurately targeted to the AVM.
31
It's an outpatient procedure.
32
You only need typically one dose of radiation and that radiation over two to three years potentially helps melt or remove the AVM from the brain.
33
This is a minimally invasive approach, and some patients like this approach for their AVM.
34
The decision on what treatment modality to use is a complex decision, and we can discuss this further at your clinic visit.

Why practice speaking with this video?

Practicing your English while watching informative videos like this one about arteriovenous malformations (AVM) offers a unique opportunity to enhance your language skills. Engaging with content that delves into complex medical topics encourages learners to acquire specialized vocabulary while also improving their overall comprehension and speaking abilities. By using the shadowing app technique, you can repeat phrases and intonations used by the speaker, which aids in developing a natural accent and fluidity in your speech. This method not only boosts your confidence but also makes learning enjoyable.

Grammar & Expressions in Context

In the video, certain grammatical structures and expressions can be particularly beneficial for learners:

  • Interrogative forms: The speaker often uses questions, such as “What is an AVM?” This structure invites listeners to engage, making it important for practice in forming questions in discussions.
  • Conditional sentences: Phrases like “if that happens” help learners understand how to articulate potential outcomes. It's a useful construction for discussing hypotheses.
  • Present continuous tense: The speaker mentions processes, saying “is a tangle of very immature blood vessels”. Practicing this tense helps learners describe ongoing actions effectively.

By focusing on these specific grammar points while practicing, you can enhance both your speaking skills and your ability to convey complex ideas succinctly.

Common Pronunciation Traps

When listening to the video, you may encounter several tricky pronunciation points that are common in advanced English. Some words to pay attention to include:

  • Arteriovenous: Break it down into syllables: ar-te-ri-o-ve-nous. This word can be challenging due to its length and rhythm.
  • Malformation: Similar to AVM, it requires careful articulation. Note the emphasis on the third syllable: mal-for-MA-tion.
  • Coagulating: The “co” in this word can often be mispronounced. Focus on the smooth transition from “co” to “agulating”.

By practicing these pronunciation traps using this video, you will sharpen your skills, making it easier to express complex medical ideas confidently during English speaking practice.

Qu'est-ce que la technique du Shadowing ?

Le Shadowing est une technique d'apprentissage des langues fondée sur la science, développée à l'origine pour la formation des interprètes professionnels. Le principe est simple mais puissant : vous écoutez de l'anglais natif et le répétez immédiatement à voix haute — comme une ombre suivant le locuteur avec un décalage de 1 à 2 secondes. Les recherches montrent une amélioration significative de la précision de la prononciation, de l'intonation, du rythme, des liaisons, de la compréhension orale et de la fluidité.
