Shadowing Practice: Aneurysm Flow Diversion - Learn English Speaking with Video
Creando lección...
1
Flow diverter stents are put across the opening of the aneurysm inside of the blood vessel.
2
So they're flush with the blood vessel wall and that bridges the opening of the aneurysm.
3
What we're using it for is the treatment of very large aneurysms on the carotid artery.
4
It's the large vessel in the front part of the brain
5
and historically these large aneurysms took very big surgical procedures to cure.
6
These stents keep branches open to the brain.
7
We deploy them through the groin.
8
We're able to lay this stent down across the opening of the aneurysm.
9
And even if we cover important vessels with that stent,
10
those vessels will stay open and feed the normal brain.
11
But the nice thing is the aneurysm shuts down over time.
12
We've been one of the first centers using this clinically.
13
It's a very good technology for treating a very difficult problem.
14
Procedure usually in the morning and you hang out in the afternoon
15
and eat and recover from the anesthesia because you are under full anesthesia for the procedure.
16
Not because it hurts, just because we don't want you moving too much.
17
And the next morning you to home.
18
The good thing about flow diverter,
19
the benefit is in the recovery time.
20
Some people do get some headaches after the procedure and a lot of the time that's related to the aneurysm clotting off.
21
There's no real restriction of activities at all,
22
mainly there's no heavy lifting and that's mainly for the groin access.
23
Just like with any stent that we put in the body,
24
typically you have to be on anti-platelet medications and that includes an aspirin and Plavix.
25
It's very important that we continue those medications.
26
There's a lot of metal that we're putting in that artery and that can activate platelets,
27
that could form blood clots,
28
and that can lead to stroke.
29
The risks to treatment are much less than they were historically
30
when we used to do big open operations with bypasses and carotid sacrifice.
31
Those complications can be any of anesthesia,
32
any time a blood clot can develop on the stent that can block an artery in the brain causing stroke.
33
And the other thing is that there can be bleeding into the brain.
34
Any time we access the artery in the groin there's a chance of a blood clot forming.
35
The real advantage to this device is it allows us in a very safe,
36
a very efficient, and very quick way to treat a once thought very complex problem.

¿Qué es la Técnica de Shadowing?
Shadowing es una técnica de aprendizaje de idiomas respaldada por la ciencia, desarrollada originalmente para la formación de intérpretes profesionales y popularizada por el políglota Dr. Alexander Arguelles. El método es simple pero poderoso: escuchas audio en inglés nativo y lo repites en voz alta de inmediato, como una sombra que sigue al hablante con solo 1-2 segundos de retraso. A diferencia de la escucha pasiva o los ejercicios de gramática, el shadowing obliga a tu cerebro y músculos de la boca a procesar y reproducir simultáneamente patrones de habla reales. Las investigaciones muestran que mejora significativamente la precisión de la pronunciación, la entonación, el ritmo, el habla conectada, la comprensión auditiva y la fluidez al hablar, convirtiéndola en una de las metodologías más efectivas para la preparación del IELTS Speaking y la comunicación en inglés en el mundo real.
