Effect of anaesthesia modality on outcome in medium or distal vessel occlusion stroke: a post-hoc analysis of the DISTAL trial

Silja Räty, Daniel Strbian, Laura Mannismäki, Mira Katan et autres

INTRODUCTION: Of the 3 published trials, only 1 showed possible efficacy of endovascular treatment (EVT) compared to best medical treatment (BMT) alone for medium or distal vessel occlusions (MDVO), whereas the others were neutral. Procedural conditions may affect the outcome. PATIENTS AND …

Role of Perfusion Parameters on Outcomes and Safety of Endovascular Therapy in Posterior Cerebral Artery Stroke

Norma J. Diel, Davide Strambo, Mohamad Abdalkader, Muhammad M. Qureshi et autres

BACKGROUND: The optimal management of isolated posterior cerebral artery occlusion (iPCAO) remains unclear. We investigated whether baseline perfusion imaging parameters are associated with clinical outcomes and whether they modify the association between endovascular therapy (EVT) and outcomes in iPCAO. METHODS: This prespecified …

CATalyze-AI: accelerating referral for thrombectomy in acute stroke patients using an AI-based software. A prospective, multicentre, quasi-experimental cohort study

Marta Olivé‐Gadea, Federica Rizzo, Dolores Cocho, Judit Roca Font et autres

INTRODUCTION: Timely transfer of patients with suspected LVO remains critical in acute stroke systems. Artificial intelligence (AI)-based imaging tools are increasingly implemented to support triage in non-thrombectomy centres. We assessed whether integrating an AI algorithm within established tele-stroke centres reduces time to …

ESUS-AI: a machine learning framework to estimate the most likely embolic source in embolic stroke of undetermined source

Adriano Bonura, Jesús M. Juega, Claudia Meza, Jordi Kühne Escolà et autres

Abstract Background and Purpose Embolic stroke of undetermined source (ESUS) emains a major diagnostic challenge in vascular neurology, as a substantial proportion of patients lack an identifiable embolic source despite standardized diagnostic workup. The failure of empiric anticoagulation strategies highlights the need …

Rescue Versus First-Line Intracranial Stenting During Thrombectomy for Acute Ischemic Stroke: A Propensity-Weighted Analysis of the RESISTANT Registry

Aarón Rodríguez-Calienes, D Yavagal, Negar Asdaghi, Marta Olivé‐Gadea et autres

BACKGROUND: While rescue stenting (RS) is a recognized bailout strategy following failed endovascular thrombectomy for acute ischemic stroke with large vessel occlusion, first-line stenting (FLS) has emerged as a potential alternative to avoid vascular injury and improve outcomes. However, direct comparisons between …

Intracranial Stenting During Acute Endovascular Therapy of Stroke: Clinical and Radiological Outcomes of the RESISTANT International Registry

Manuel Requena, Marta Olivé‐Gadea, Francesco Diana, Johannes Kaesmacher et autres

BACKGROUND: In the case of failed reperfusion or severe stenosis during endovascular treatment of acute stroke, intracranial stenting is a growing practice. We aimed to study clinical and radiological outcomes in a large multicenter cohort. METHODS: The RESISTANT registry (Registry of Endovascular …

Safety and efficacy of intravenous thrombolytics among patients with emergent intracranial stenting after thrombectomy: Subanalysis of the RESISTANT registry

Adnan Mujanović, Marta Olivé‐Gadea, Francesco Diana, Greta Sökeland et autres

BACKGROUND: The value of intravenous thrombolysis (IVT) prior to endovascular therapy (EVT) with emergent stenting for intracranial atherosclerotic disease (ICAD)-large vessel occlusion (LVO) is unknown. We aimed to investigate the safety and efficacy of IVT among patients with adjuvant intracranial stenting after …

Outcomes of Witnessed Versus Unwitnessed Patients With Stroke After Endovascular Therapy in the Extended Time Window

Liisa Tomppo, Nicolas Martinez‐Majander, Muhammad M. Qureshi, Thanh N. Nguyen et autres

BACKGROUND: It remains unclear whether outcomes of patients treated with endovascular thrombectomy with large-vessel occlusion and unwitnessed onset of stroke differ from those with witnessed onset in the extended time window. METHODS: We enrolled patients with anterior circulation large-vessel occlusion (internal carotid …

Socioeconomic Deprivation in Ischemic Stroke Treated With Endovascular Thrombectomy: Not All Recoveries Are Equal

Carlos Martinez Montalvo, Álvaro García‐Tornel, Marta Olivé‐Gadea, Marc Rodrigo‐Gisbert et autres

BACKGROUND: The influence of socioeconomic deprivation on outcomes in ischemic stroke patients treated with thrombectomy remains unclear. METHODS: We analyzed 6219 patients with ischemic stroke treated with thrombectomy between 2016 and 2023 in Catalonia, Spain. Socioeconomic deprivation was defined at the health …

Evaluation of a Deep Learning Tool for Detecting Large Vessel Occlusion and Intracranial Hemorrhage on Noncontrast Computed Tomography Scans

Xabier Urra, Ansaar Rai, María Hernández‐Pérez, Demetrius K. Lopes et autres

BACKGROUND: The purpose of this study is to assess the accuracy of automated artificial intelligence (AI) deep-learning-based modules in predicting suspected intracranial hemorrhage (ICH) or anterior circulation large vessel occlusion (LVO) on noncontrast computed tomography (NCCT) studies. METHODS: We conducted a multicenter …

Abstract 494: Predictors to Endovascular Therapy in Patients with Middle Vessel Occlusions

Alberto Brito, Eric Kontowicz, W. D. Haselden, Manuel Requena et autres

Introduction/Purpose Randomized trials suggest endovascular therapy (EVT) may not benefit patients with medium vessel occlusions (MeVOs), though heterogeneity—inclusion of very mild cases—limits interpretation. We aimed to model 90‐days functional outcomes in MeVO patients to better identify high‐risk patients. Materials/Methods This is a …
