1
In this video, we will discuss about right lateral frontal AVM,
2
its angio-architecture and embolization.
3
28-year female, presented with right frontal partial seizure,
4
on and off right frontal headache.
5
CT scan with contrast showed right frontal AVM.
6
This is lateral view of right internal calvary artery injection which showed high flow AVM at right anterior frontal region.
7
Avium is fed by multiple feeders from right middle subal artery and anterior subal artery.
8
The Avium is drained via dilated right anterior frontal cortical vein to superior cital sinus.
9
From a surgeon perspective, Avium core can be considered as a box shape with a forced surface.
10
Here we are seeing the Avium from the anterior aspect,
11
posterior aspect, right lateral and left lateral aspect.
12
In this particular case, the AVM feeders are entering the AVM core from the inferior aspect
13
and the draining vein is exiting from the anterior aspect of the AVM.
14
This is the sketch diagram of AVM.
15
Here we could see the circumferential feeder artery branching into smaller shunting arterioles
16
which is shunting the blood to the spiral shaped vessels within the central core.
17
These spiral vessels are either veins or are dysmorphic vessels.
18
These spiral vessels are finally draining to superficial cortical vein.
19
On the left side of the screen we could see the selective injection of the feeder artery.
20
Here we could see the feeder artery is dividing into tiny vessels
21
which are shunting arterioles
22
which is then shunting the blood to the spiral vessels within the AVM core
23
and we could also see the faint visualization of the draining vein.
24
In this case the AVM is located at right anterior frontal lobe involving lateral and the orbital surface.
25
Prefrontal branch of the midislebar artery supply most of the middle frontal gyrus and part of inferior frontal gyrus.
26
Orbitofrontal branch of the midislebar artery supply orbital portion of middle and inferior frontal gyri.
27
In this case, the AVM is predominantly supplied by the orbitofrontal branch and prefrontal branch of right middle silver artery.
28
This AVM is also supplied by the frontopolar branch and anterior internal frontal branch of enterosilber artery.
29
These feeders from enterosilber artery traversing along the medial surface of hemisphere reaching the frontal pole
30
and then supplying the avium on the lateral surface of the frontal lobe.
31
This is right middle meningeal artery injection which showed supply to the basal portion of the avium nidus.
32
The avium nidus is then draining via superficial frontal cortical vein anteriorly and via orbital vein to the sylvan vein posteriorly.
33
This 3D fusion image showed two separate components of the avium nidus,
34
anterior superior portion of the avium nidus fed by the intracranial feeders
35
and basal portion of the avium nidus are fed by middle meningeal artery feeders.
36
The avium was planned for stage embolization with aim to achieve cure by endovascular root.
37
In the first session three feeders were selectively catheterized and avium nidus was embolized.
38
This is selective micro catheter injection of prefrontal branch of right MCA which was embolized using squid.
39
This is right middle feeder artery injection and this feeder artery was embolized using 20% glue.
40
Finally, right frontopolar feeder artery was selectively catheterized using magic microcatheter and was embolized using 20% glue.
41
This is the final embolic cast.
42
Final angiogram revealed approximately 50% reduction of the AVM NIDA score.
43
Thank you.

本课介绍
在这一节中，学习者将聚焦于右侧额叶动静脉畸形（AVM）及其栓塞过程的相关医学英语。这段视频详细描述了如何通过影像学和血管介入技术来处理年轻女性患者的AVM，为学习者提供了丰富的医学术语和表达，用以提升他们的专业英语水平。通过观看这段YouTube视频，学习者不仅能够掌握相关的专业知识，还能通过模仿讲话者的语调和语速，增强他们的口语能力。
关键词汇与短语
- 动静脉畸形 (AVM) - Arteriovenous Malformation
- 栓塞 (Embolization) - Embolization
- 造影 (Contrast) - Contrast Imaging
- 输送血管 (Feeder Artery) - Feeder Artery
- 脑动脉 (Artery) - Artery
- 静脉 (Vein) - Vein
- 影像学 (Angiography) - Angiography
- 医学术语 (Medical Terminology) - Medical Terminology
练习技巧
为了充分利用这一视频学习英语，建议学习者采用shadow speech或shadowspeak的方式进行练习。在观看视频时，尝试模仿讲话者的语音、语调及节奏。视频中的医学内容可能会比较复杂，因此初次观看时可以选择打开字幕，帮助理解每个术语的具体含义。在熟悉后，再次观看时尝试关闭字幕，专注于语音的模仿。这样不仅能提升语言的理解能力，还是非常有效的口语练习。借助这个shadowing site，学习者可以逐步提高自己的口语流利度和发音准确性。
此外，建议学习者定期回顾这些专业词汇，并尝试在日常对话中使用它们。通过这样的方式，可以更好地将新学的词汇运用于实际情境中，增强记忆，并提升表达能力。无论是准备考试还是希望在医疗领域获得更多的交流能力，观看看YouTube学英语这类专业视频都是一个很好的选择。
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。
