Genetic Study of White Matter Integrity in UK Biobank (N=8448) and the Overlap With Stroke, Depression, and Dementia Clinical Sciences
Conclusions—Genetic variants within the VCAN gene may play a role in the mechanisms underlying microstructural integrity of the white matter in the brain measured as FA and MD. Mechanisms underlying white matter alterations are shared with cerebrovascular disease, and inherited differences in white matter microstructure impact on Alzheimer disease and major depressive disorder.

Declining Rate and Severity of Hospitalized Stroke From 2004 to 2013 Clinical Sciences
Background and Purpose—Stroke is a leading cause of morbidity and disability. We assessed trends in rates of hospitalized stroke and stroke severity on admission in a prospective national registry of stroke from 2004 to 2013.Methods—All 6693 acute ischemic strokes and intracerebral hemorrhage in the National Acute Stroke Israeli participants ≥20 years old were included. Data were prospectively collected in 2004 (February–March), 2007 (March–April), 2010 (April–May), and 2013 (March–April). Rates of hospitalized stroke from 2004 to 2013 were studied using generalized linear models assuming a quasi-Poisson erro...

Multivessel Occlusion in Patients Subjected to Thrombectomy Clinical Sciences
Background and Purpose—Patients with embolic large-vessel occlusion may present with additional coincidental acute occlusions within or distant from the involved territory, referred to as multivessel occlusion (MVO). Purpose of this study was to assess prevalence of MVO, associated factors, and clinical relevance in patients undergoing endovascular stroke treatment.Methods—Image data of consecutive endovascular candidates (n=720) with direct access to angiography were extracted from a prospective registry. Prevalence of MVO was assessed with multimodal magnetic resonance imaging/computed tomography and confirmed by int...

Perimesencephalic Hemorrhage Clinical Sciences
Conclusions—A single, high-quality computed tomography angiography is the preferred diagnostic strategy. Short-term complications are rare and often transient. Long-term outcome is excellent with respect to disability and death, but high-quality studies focused at neuropsychological sequelae are needed.

Association of Basilar Bifurcation Aneurysms With Age, Sex, and Bifurcation Geometry Clinical Sciences
Background and Purpose—Basilar artery (BA) bifurcation aneurysms are common, but the correlation between BA bifurcation morphology and aneurysm formation remains to be established. Our purpose was to determine the association of BA bifurcation aneurysms with patient age, sex, bifurcation angle, and branch diameter.Methods—Three-dimensional angiographic data of 195 patients were used, including 59 patients with BA bifurcation aneurysms and 136 control subjects. The angles formed between left and right posterior cerebral arteries (φ1) and between posterior cerebral artery and BA (the smaller angle defined as φ2 and the...

Intravenous Recombinant Tissue-Type Plasminogen Activator Clinical Sciences
Conclusions—In this population, previous IVT improved functional outcome and survival at 3 months in patients treated by MT. While waiting for randomized controlled trials, this result encourages not to avoid IVT before MT.

Progression of White Matter Hyperintensities Preceded by Heterogeneous Decline of Microstructural Integrity Clinical Sciences
Conclusions—Impaired microstructural integrity preceded conversion into WMH and continuously declined over time, suggesting a continuous disease process of white matter integrity loss that can be detected using diffusion tensor imaging even years before WMH become visible on conventional neuroimaging. Differences in microstructural integrity between participants with mild versus severe WMH suggest heterogeneity of both NAWM and WMH, which might explain the clinical variability observed in patients with similar small vessel disease severity.

Prediction of Tissue Outcome and Assessment of Treatment Effect in Acute Ischemic Stroke Using Deep Learning Clinical Sciences
Background and Purpose—Treatment options for patients with acute ischemic stroke depend on the volume of salvageable tissue. This volume assessment is currently based on fixed thresholds and single imagine modalities, limiting accuracy. We wish to develop and validate a predictive model capable of automatically identifying and combining acute imaging features to accurately predict final lesion volume.Methods—Using acute magnetic resonance imaging, we developed and trained a deep convolutional neural network (CNNdeep) to predict final imaging outcome. A total of 222 patients were included, of which 187 were treated with...

Magnetic Resonance Imaging Selection for Endovascular Stroke Therapy Clinical Sciences
Conclusions—Workflow in GOLIATH demonstrates that magnetic resonance imaging selection for endovascular therapy can be accomplished rapidly and within a similar time frame as computed tomography-based selection.Clinical Trial Registration—URL: https://www.clinicaltrials.gov. Unique identifier: NCT02317237.

Clinical Utility of Electronic Alberta Stroke Program Early Computed Tomography Score Software in the ENCHANTED Trial Database Clinical Sciences
Background and Purpose—Clinical utility of electronic Alberta Stroke Program Early CT Score (e-ASPECTS), an automated system for quantifying signs of infarction, was evaluated in a large database of thrombolyzed patients with acute ischemic stroke.Methods—All baseline noncontrast computed tomographic scans of patients with anterior circulation acute ischemic stroke who participated in the alteplase dose arm of the randomized controlled trial ENCHANTED (Enhanced Control of Hypertension and Thrombolysis Stroke Study) were reviewed; poor quality and large (>6 mm) slice thickness were excluded. Included scans had e-ASPECTS...

Delays in the Air or Ground Transfer of Patients for Endovascular Thrombectomy Clinical Sciences
Background and Purpose—For suspected large vessel occlusion patients efficient transfer to centers that provide endovascular therapy (ET) is critical to maximizing treatment opportunity. Our objective was to examine associations between transfer time, modes of transfer, ET, and outcomes within a hub-and-spoke telestroke network.Methods—Patients with ischemic stroke were included if transferred to a single hub hospital between January 2011 and October 2015 with National Institutes of Health Stroke Scale>6, onset

Computed Tomographic Perfusion Predicts Poor Outcomes in a Randomized Trial of Endovascular Therapy Clinical Sciences
Conclusions—The majority of patients with CTP imaging in the ESCAPE trial had penumbral patterns, which were associated with better outcomes overall. Patients with penumbra treated with endovascular therapy had the greatest odds of good functional outcome. Nonpenumbral patients were much less likely to achieve good outcomes.

Antiplatelet Treatment After Transient Ischemic Attack and Ischemic Stroke in Patients With Cerebral Microbleeds in 2 Large Cohorts and an Updated Systematic Review Clinical Sciences
Background and Purpose—In patients with transient ischemic attack/ischemic stroke, microbleed burden predicts intracerebral hemorrhage (ICH), and ischemic stroke, but implications for antiplatelet treatment are uncertain. Previous cohort studies have had insufficient follow-up to assess the time course of risks, have not stratified risks by antithrombotic use, and have not reported extracranial bleeds or functional outcome of ICH versus ischemic stroke.Methods—In 2 independent prospective cohorts with transient ischemic attack/ischemic stroke (Oxford Vascular Study/mainly white; University of Hong Kong/mainly Chinese),...
