Hello, I'm Dr. Hisham Salahuddin.
2
In today's Sphinits, we will explore the management of tandem occlusions, a complex and evolving area in acute stroke management.
3
Tandem occlusions involve severe stenosis or occlusion of an extracranial vessel,
4
typically the cervical internal carotid artery accompanied by an intracranial occlusion.
5
This dual occlusion presents unique challenges in both medical and neuroendovascular treatment.
6
Tandem occlusions are often associated with a high clot burden, particularly if the extracranial lesion is occluded.
7
Many questions remain about the optimal management of tandem occlusions as no randomized studies have specifically addressed this group.
8
Data only exists from multi-center registries and meta-analysis.
9
Key questions include the role of intravenous thrombolysis, endovascular approach to extra or intracranial recanalization first,
10
the use of acute angioplasty or stenting, and post-procedural antiplatelet regimens.
11
Clinical trials have shown that adding IV thrombolysis to mechanical thrombectomy is not non-inferior to MT alone.
12
However, given the large clot burden and frequent post-procedural antiplatelet needs, some question its routine use in tandem occlusions.
13
A pooled analysis of the Titan and Etis registries demonstrated improved recanalization
14
and functional outcomes without an increase in symptomatic ICH with IV thrombolysis in this setting.
15
A meta-analysis of over 1,800 patients across nine studies also supports its use.
16
Administration of IV thrombolysis for tandem occlusions is safe and effective.
17
Neuroendovascular treatment can involve an extracranial first or anterograde approach, addressing the proximal lesion first,
18
or an intracranial first or retrograde approach, targeting the distal occlusion first.
19
Endovascular approach is often influenced by occlusion etiology, degree of stenosis, and operator preference and experience.
20
An intracranial first or retrograde approach may result in faster recanalization times
21
and data from a German observational registry along with a meta-analysis by Zavellas
22
and colleagues suggest that this could lead to improved clinical outcomes.
23
While acute stenting for tandem occlusions requires post-procedural antithrombotics,
24
The rates of symptomatic hemorrhage are comparable to those in patients who do not undergo stenting.
25
Acute stenting has demonstrated better clinical outcomes than angioplasty alone in two large multi-center studies with over 600 patients each,
26
as well as in a meta-analysis of nearly 6,400 patients.
27
However, the effectiveness of stenting may be influenced by the underlying proximal etiology, whether due to carotid atherosclerosis or dissection.
28
Following intervention, acute antiplatelet therapy is essential to prevent reocclusion.
29
Approaches vary widely as revealed from a survey of 209 neurointerventionists with diverse training backgrounds.
30
Some practitioners prefer dual antiplatelet therapy to mitigate immediate thrombotic risks, while others choose a single agent based on bleeding risk.
31
The optimal antiplatelet protocol remains an area of active investigation.
32
While we've made significant progress, important questions remain.
33
Ongoing research including trials such as the PICASO, TITAN and Eastside Talk will help answer these questions and refine our treatment algorithms.
34
In summary, tandem occlusion management is multifaceted.
35
Advances in research continue to shape best practices, helping to optimize outcomes in this challenging patient population.
36
Both IV thrombolysis and acute stenting appear to be safe and effective effective.
37
Both anterograde or retrograde approaches are viable.
38
Though an intracranial first approach may offer greater benefit, data is currently insufficient to support a specific antiplatelet regimen.
39
Thank you for joining this discussion on tandem occlusions.

쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법
쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
