Robotic-assisted carotid artery stenting with R-One: Feasibility and safety assessment in patients with carotid web lesions.

PurposeRobotic-assisted carotid artery stenting (CAS) procedures are on the rise and have demonstrated benefits compared to manual intervention. The R-OneTM robotic platform has demonstrated safety and efficacy for percutaneous coronary interventions, but its utility for procedures in the common carotid artery has not been thoroughly studied. This study aims to assess the feasibility and initial safety of the R-OneTM robotic platform for treating patients with carotid artery disease (CAD) presenting with carotid web-diaphragm lesions.

Imaging follow-up of unruptured intracranial aneurysms treated with flow diverter: Insights from a French collaborative survey.

Purpose: The absence of standardized guidelines for imaging follow-up of unruptured intracranial aneurysms treated with flow diverters (FD) results in significant variability across centers. This survey aims to provide a comprehensive overview of current imaging follow-up practices in French academic centers.

Methods: In April 2024, a 49-question survey was distributed to interventional neuroradiology centers in France through the trainee-led research collaborative network, Jeunes En Neuroradiologie Interventionnelle-Research Collaborative (JENI-RC).

Iatrogenic emboli during mechanical thrombectomy for acute ischemic stroke: comparison between stent retriever technique and contact aspiration-a retrospective case-control study.

Background: Mechanical thrombectomy (MT) is an effective treatment for acute ischemic stroke from large vessel occlusion (LVO). While embolization to a new territory (ENT) after MT is well-documented, data on embolization in the same distal territory (EDT) are limited. Achieving modified Treatment In Cerebral Infarction (mTICI) 3 reperfusion presents significant clinical benefits over mTICI 2b/2c, necessitating strategies to reduce both ENT and EDT.

Mechanical thrombectomy in basilar artery occlusions: impact of first-line strategy as a function of the occlusion level.

Background: Retrospective studies suggest the superiority of first-line contact aspiration (CA) thrombectomy over stent-retriever (SR) in basilar artery occlusions (BAO). We aimed to investigate the impact of first-line mechanical thrombectomy per the occlusion level, considering differences in stroke etiology prevalence between proximal and distal BAO.

Methods: A retrospective, multicentric analysis of the Endovascular Treatment in Ischemic Stroke Registry (ETIS) included consecutive BAO patients treated from January 2016 to May 2022.

Temporal trends in results of endovascular treatment of anterior intracranial large cerebral vessel occlusion: A 7-year study.

Background: Technical improvements in devices, changes in angiographic grading scales and various confounding factors have made difficult the detection of the temporal evolution of angiographic and clinical results after endovascular treatment (EVT) for acute ischemic Stroke (AIS). We analyzed this evolution in time using the Endovascular Treatment in Ischemic Stroke (ETIS) registry.

Materials And Methods: We analyzed the efficacy outcomes of EVT performed from January 2015 to January 2022, and modelized the temporal trends using mixed logistic regression models, further adjusted for age, intravenous thrombolysis prior to EVT, general anesthesia, occlusion site, balloon catheter use and the type of first-line EVT strategy.

Mortality and functional outcome after pediatric intracerebral hemorrhage: cohort study and meta-analysis.

Objective: The clinical outcome of pediatric intracerebral hemorrhage (pICH) is rarely reported in a comprehensive way. In this cohort study, systematic review, and meta-analysis of patients with pICH, the authors aimed to describe the basic clinical outcomes of pICH.

Methods: Children who received treatment for pICH at the authors' institution were prospectively enrolled in the cohort in 2008; data since 2000 were retrospectively included, and data through October 2019 were analyzed.

Acute surgical management of children with ruptured brain arteriovenous malformation.

Objective: Rupture of brain arteriovenous malformation (AVM) is the main etiology of intracerebral hemorrhage (ICH) in children. Ensuing intracranial hypertension is among the modifiable prognosis factors and sometimes requires emergency hemorrhage evacuation (HE). The authors aimed to analyze variables associated with HE in children with ruptured AVM.

Hemorrhage Expansion After Pediatric Intracerebral Hemorrhage.

Background And Purpose: Significant hemorrhage expansion (sHE) is a known predictor of poor outcome after an intracerebral hemorrhage (ICH) in adults but remains poorly reported in children. In a large inception cohort, we aimed to explore the prevalence of sHE, its associations with clinical outcomes, and its clinical-imaging predictors in children.

Methods: Children admitted between January 2000 and March 2020 at a quaternary care pediatric hospital were screened for inclusion.

Etiology of intracerebral hemorrhage in children: cohort study, systematic review, and meta-analysis.

Objective: Understanding the etiological spectrum of nontraumatic pediatric intracerebral hemorrhage (pICH) is key to the diagnostic workup and care pathway. The authors aimed to evaluate the etiological spectrum of diseases underlying pICH.

Methods: Children treated at the authors' institution for a pICH were included in an inception cohort initiated in 2008 and retrospectively inclusive to 2000, which was analyzed in October 2019.

First Line Onyx Embolization in Ruptured Pediatric Arteriovenous Malformations : Safety and Efficacy.

Purpose: Brain arteriovenous malformations (bAVM) are the main cause of pediatric intracerebral hemorrhage (pICH). Embolization with Onyx (ev3, Irvine, CA, USA) in children with ruptured bAVM has been infrequently reported. The aim of this study was to assess the safety and efficacy profile of Onyx embolization as first line endovascular treatment of ruptured pediatric bAVMs.

Long-term Outcomes of Cerebral Aneurysms in Children.

Background: Our aim was to report the long-term clinical and imaging outcomes of ≤15-year-old children treated for ruptured or symptomatic cerebral aneurysms and to identify prognostic factors for clinical outcome, recurrence, and rebleeding.

Methods: We retrospectively identified all pediatric cases of cerebral aneurysm from 2000 to 2015 and then prospectively evaluated long-term occlusion using brain MRI and clinical outcome measures: outcome was considered favorable if King's Outcome Scale for Childhood Head Injury score was ≥5. We performed univariate analysis and logistic binary regression to identify variables associated with clinical and imaging outcomes.
