Well hi, it's a real treat to be with you here today

and talk to you about super large borothrombectomy and why you ought to be including these tools into your arsenal against stroke.

I'm Sunil Sheth, I'm an associate professor at UT Health, vascular interventional neurology.

So what is super large borothrombectomy?

Here we're talking about aspiration using 88 inch diameter catheters or greater.

The whole theory behind this approach is that these are catheters that are sized to match your target vessel.

So you can see here the sizes of the different vessels

that we approach and the most common occlusion that we face in the world of LVO is M1 occlusions.

88 catheters will match

that outer diameter to the vessel much better than any of the other catheter shapes and sizes that we have.

Why is vessel matching so important.

First is this concept of flow arrest, stopping enterograde flow and preventing distal embolization.

It also, with larger inner diameter, is going to increase your aspiration force.

This means you'll have more effective thrombectomy and then with that have less likelihood of distal embolization.

So overall that translates to better first-pass reperfusion and that's really the target of every thrombectomy approach is improving that first-pass

re-canalization and in in vitro studies large-bore aspiration has shown to do that.

So as you put the catheter into the vessel you not only stop intergrade flow substantially

but once you turn on aspiration the flow reverses and this is going to prevent dislembolization and also retain the clot

in a much better fashion.

So with in vitro data we have moved on to in vivo studies

and if we look So if you look at how thrombectomy has changed over time, in the bad old days of mercy, well, it didn't really work,

but really in the last 10 years we're talking about 2015

to 2024 first pass effect has really languished in this 20 to 30 percent range where although we get bigger

and bigger aspiration catheters going up to the 070 range the

first pass effect has not substantially improved since the early days of stent retrievers back in 2015.

So we need a step function we need a real step up in our performance

and that's where super large has come in we want to get above at least 60% first pass effect.

We are now living in a world where we actually have randomized and prospective trial data showing that we are there.

This was one trial that was presented in the summer of 2025 from the perfuse company in the MARS trial.

This is their primary efficacy data and as you can see here first pass effect with TIKI 2C 3 or greater.

So this is not the usual 2B or greater, but 2C or greater, 61% with their millipede system.

And in the M1, again, where you have vessel matching, 77%.

These are numbers we have never seen before in rigorously collected prospective clinical trial data.

Similarly, from the Route 92 group,

the Summit Max trial was a randomized trial comparing their device against a 70 diameter catheter 74 and significantly better reperfusion results.

So just to summarize, we are now living in the world of super large-bore thrombectomy.

Super large-bore thrombectomy is the first real improvement on first-pass effect

we've ever had in the last decade since we've been doing thrombectomy.

So it's not a question of should you be doing thrombectomy, it's with super large bore catheters is

if you want to provide the best care for your patients you need start including these tools into your arsenal.

Thank you and appreciate this opportunity.

本課的詞彙與口語要點

這節 C1 級別的口語課以影片“SVINutes: Super Large Bore Thrombectomy”為素材。影片中反覆出現的詞有：catheter, thrombectomy, pass, vessel, trial。這段影片共有 41 個句子、603 個單詞可供跟讀。講話部分時長為 3:38。說話人語速自然，每分鐘約 166 個詞，接近日常對話。只有 81% 的單詞屬於英語最常用的 3,000 詞，詞彙難度較高。

影片中的重點詞彙

影片中最難的 14 個單詞，附發音和釋義：

單詞	發音	釋義
catheter 名詞	/ˈkæθɪtɚ/	導管 /導管
aspiration 名詞	/ˌæspəˈɹeɪʃən/	希望
diameter 名詞	/daɪˈæmɪdɚ/	直徑 /直徑
distal 形容詞	/ˈdɪs.təl/	末梢部的
substantially 副詞		實貭上地 /實貭上地
languish 動詞	/ˈlæŋ.ɡwɪʃ/	憔悴
millipede 名詞	/ˈmɪləpid/	馬陸 /馬陸, 千足蟲 /千足蟲
neurology 名詞	/n(j)ʊ(ə)ˈɹɒləd͡ʒi/	神經學 /神經學
retriever 名詞	/ɹiˈtɹivəɹ/	尋回犬 /尋回犬
summarize 動詞	/ˈsʌməˌɹaɪz/	摘要, 總結 /總結

translate 動詞	/tɹænzˈleɪt/	翻譯 /翻譯, 譯 /譯

影片中的語法

說話人最常用的結構，並附上影片中的原話：

結構	影片中的用法
現在完成時 have/has + 過去分詞 — 過去發生但與現在仍有關聯的事	has shown · have moved · has changed
被動語態 be + 過去分詞 — 強調發生了什麼，而不是誰做的	are sized · was presented

需要注意的發音

“sh” 和 “zh” 音: aspiration /ˌæspəˈɹeɪʃən/, occlusion /əˈkluː.ʒən/, canalisation /ˌkænələˈzeɪʃən/, interventional /ˌɪn.təɹˈvɛn.ʃə.nəl/, languish /ˈlæŋ.ɡwɪʃ/
長單詞——注意重音位置: aspiration /ˌæspəˈɹeɪʃən/, diameter /daɪˈæmɪdɚ/, canalisation /ˌkænələˈzeɪʃən/, interventional /ˌɪn.təɹˈvɛn.ʃə.nəl/, neurology /n(j)ʊ(ə)ˈɹɒləd͡ʒi/

中文母語者容易讀錯的音：

/v/ — 不要讀成 /w/，上齒輕觸下唇: prospective /pɹəˈspɛktɪv/, interventional /ˌɪn.təɹˈvɛn.ʃə.nəl/, retriever /ɹiˈtɹivəɹ/, vascular /ˈvæskjələ/
詞尾子音 — 要讀清楚，後面不要加母音: prospective /pɹəˈspɛktɪv/, languish /ˈlæŋ.ɡwɪʃ/, millipede /ˈmɪləpid/, perfuse /pəɹˈfjuːz/, summarize /ˈsʌməˌɹaɪz/
/r/ 和 /l/ 的區別: interventional /ˌɪn.təɹˈvɛn.ʃə.nəl/, neurology /n(j)ʊ(ə)ˈɹɒləd͡ʒi/, translate /tɹænzˈleɪt/

如何用這段影片練習

先完整聽一遍影片，不要開口，記下不認識的單詞。
先用 0.75 倍速逐句跟讀，熟練之後再回到正常速度。
錄下自己的聲音並與原聲對比，特別注意 catheter, aspiration, diameter 這類單詞。

什麼是跟讀法？

跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
