Article Abstract

Background: ST-elevation myocardial infarction (STEMI) is typically caused by thrombotic occlusion of a coronary artery with subsequent hypoperfusion and myocardial necrosis. In approximately half of patients with STEMI, despite successful restoration of epicardial coronary patency, downstream myocardium perfusion remains impeded. Coronary microvascular injury is one of the key mechanisms behind suboptimal myocardial perfusion and it is primarily, yet not exclusively, related to distal embolization of atherothrombotic material following recanalization of the culprit artery. Routine manual thrombus-aspiration has failed to show clinical efficacy in this scenario. This could be related with limitations in technology adopted as well as patients' selection. To this end, we set out to explore the efficacy and safety of stent retriever-assisted thrombectomy based on clot-removal device routinely used in stroke intervention.

Study Design And Objectives: The stent RETRIEVEr thrombectomy for thrombus burden reduction in patients with Acute Myocardial Infarction (RETRIEVE-AMI) study has been designed to establish whether stent retriever-based thrombectomy is safe and more efficacious in thrombus modification than the current standard of care: manual thrombus aspiration or stenting. The RETRIEVE-AMI trial will enrol 81 participants admitted for primary PCI for inferior STEMI. Participants will be 1:1:1 randomised to receive either standalone PCI, thrombus aspiration and PCI, or retriever-based thrombectomy and PCI. Change in thrombus burden will be assessed via optical coherence tomography imaging. A telephone follow-up at 6 months will be arranged.

Conclusions: It is anticipated by the investigators that stent retriever thrombectomy will more effectively reduce the thrombotic burden compared to current standard of care whilst being clinically safe.

Background: The ESCAPE-MeVO (Endovascular Treatment to Improve Outcomes for Medium Vessel Occlusions) and DISTAL (Endovascular Therapy plus Best Medical Treatment vs Best Medical Treatment Alone for Medium Vessel Occlusion Stroke) trials failed to demonstrate the superiority of endovascular thrombectomy over best medical management for medium and small vessel occlusions. Potential limitations of these trials include older patient populations, lower presenting National Institutes of Health Stroke Scale (NIHSS) scores, higher rates of premorbid disability, delayed revascularization times, inclusion of both medium and small vessel occlusions, and widespread use of stent retrievers. Here we present M2 occlusion data from the Imperative Trial, evaluating aspiration thrombectomy with the Zoom System.

Background: Endovascular thrombectomy is the primary treatment for acute basilar artery occlusion (BAO), with direct aspiration (DA) and stent retriever (SR) as the main techniques. This updated meta-analysis aims to compare these two techniques in terms of efficacy and safety outcomes.

Methods: A search was performed across PubMed, Embase, and Cochrane databases on December 23, 2024.

PurposeThe efficacy of mechanical thrombectomy (MT) for M2 occlusion remains uncertain, partly due to recanalization challenges owing to anatomical factors and hemorrhagic complications. This study investigated the best method for M2 occlusion based on the M1-M2 bifurcation angle.MethodsWe retrospectively evaluated the clinical data of 134 consecutive patients with M2 occlusion who underwent MT.

Acute basilar artery occlusion (BAO) can lead to severe stroke and is linked to significant disability or death if not treated. This meta-analysis evaluated the effectiveness and safety of first-line thrombectomy options: Direct Aspiration (DA) and Stent Retriever Thrombectomy (SRT) for acute BAO. Electronic databases, including PubMed, Cochrane Central, ScienceDirect, Embase, and Web of Science were searched from inception until July 2025.

Medium vessel occlusions represent a substantial proportion of patients with acute ischemic stroke. Recently presented randomized controlled trials, ESCAPE-MeVO (Endovascular Treatment to Improve Outcomes for Medium Vessel Occlusions), DISTAL (Endovascular Therapy Plus Best Medical Treatment [BMT] Versus BMT Alone for Medium Distal Vessel Occlusion Stroke), and DISCOUNT (Evaluation of Mechanical Thrombectomy in Acute Ischemic Stroke Related to a Distal Arterial Occlusion), did not demonstrate a clinical benefit of endovascular thrombectomy in distal and medium vessel occlusions, potentially generating uncertainty about optimal treatment strategies for medium vessel occlusions. Specifically, these results may lead clinicians to hesitate in performing endovascular thrombectomy for M2 occlusions, despite prior evidence indicating benefit in this subgroup.
