Insights
Endovascular reperfusion significantly improves outcomes for acute ischemic stroke patients with large-vessel occlusion. Advances in devices and techniques have transformed treatment effectiveness since 2015.
Area of Science:
- Neurology
- Interventional Cardiology
- Medical Device Technology
Background:
- Stroke is a leading cause of death and disability globally.
- Acute ischemic stroke accounts for 85% of strokes, with large-vessel occlusion leading to poor outcomes.
- Early endovascular treatments faced challenges, with 3 failed trials in 2013.
Purpose of the Study:
- To review the evolution of endovascular treatment for acute ischemic stroke.
- To highlight technical and technological advancements in endovascular devices and techniques.
- To analyze patient selection, procedural, and clinical outcomes from key trials.
Main Methods:
- Review of historical and recent randomized clinical trials on endovascular reperfusion.
- Analysis of device technology and procedural techniques for acute ischemic stroke.
- Examination of patient selection criteria and clinical outcomes.
Main Results:
- Significant improvements in safety, speed, and reperfusion completeness.
- Nine randomized trials since 2015 consistently show overwhelming benefits of endovascular reperfusion.
- Advancements have overcome previous limitations in device technology and treatment selection.
Conclusions:
- Endovascular reperfusion is a highly effective treatment for acute ischemic stroke.
- Technological and technical progress has revolutionized stroke intervention outcomes.
- Continued research in patient selection and procedural optimization is crucial.
Abstract:
Stroke is the major cause of disability and the second leading cause of death worldwide. Acute ischemic stroke is responsible for ∼85% of all strokes, with 24% to 46% attributable to large-vessel occlusion, which are typically associated with worse outcomes. Although the initial efforts to develop endovascular treatment for acute ischemic stroke took place over 6 decades ago, critical gaps in device technology and treatment selection existed, resulting in 3 failed randomized clinical trials published in 2013. Fortunately, devices and techniques have dramatically evolved over the past decade, leading to significant improvements in the safety, speed, and completeness of reperfusion. Since 2015, a total of 9 randomized trials have consistently demonstrated an overwhelming benefit to endovascular reperfusion. In this article, we will review the evolution of endovascular treatment for acute ischemic stroke, including the technical and technological advances as well as the perspectives in terms of patient selection and procedural and clinical outcomes of the landmark past and recent trials.
