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.

为什么要通过这个视频练习说话？
看YouTube学英语是提高口语能力的一个有效方法。通过这个视频，您可以深入了解脑动脉瘤流动分流的治疗方法，同时练习与医疗相关的英语表达。视频中的讲解不仅专业而且清晰，使您能够在真实的医学语境中学习和应用新词汇与结构。这种方式有助于强化您的英语口语练习，尤其是在进行雅思口语练习时，能够提升您在专业领域对话的自信心。
语法与表达的语境分析
- 使用“be put across”结构：视频中提到“Flow diverter stents are put across the opening...”表明了被动语态的使用，适合用于描述医学程序。理解被动语态有助于您在英语口语练习中更有效地表达某些动作的承受者。
- 条件句的应用：讲者提到“Even if we cover important vessels with that stent, those vessels will stay open...” 这种条件句的用法为您提供了在谈论复杂情形时如何使用英语表达可能性与结果的学习机会。
- 时间副词的表达：使用诸如“usually in the morning”和“the next morning you go home”帮助您掌握描述事件时间顺序的能力，这在口语交流中是非常重要的。
常见的发音陷阱
在视频中，有几个发音可能成为学习者的障碍。例如，“aneurysm”（动脉瘤）的发音较为复杂，可能会导致难以准确表达。此外，“diverter”这个单词也需要特别注意其重音位置。在进行英语影子跟读时，您可以通过多次重复练习这些词汇，提升发音的准确性。这种方式不仅能帮助您解决发音问题，也能增强您的语言流利度。
总结来说，通过结合看YouTube学英语与shadow speech，您可以在理解复杂术语的同时，通过英语口语练习和雅思口语练习来提升语言能力。掌握这些医学领域的表达，不仅能拓宽您的词汇量，还能在必要时有效沟通。记得在每天的练习中加入英语影子跟读的活动，让自己的英语水平更上一层楼。
什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
