Large Middle Cerebral Artery Ischemic Stroke in a Therapeutically Anticoagulated Patient With Severe SARS-CoV-2 Infection
Introduction: Coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is associated with hypercoagulability which can predispose infected patients to both arterial and venous thromboembolic complications. Despite therapeutic anticoagulation, there remains a risk of ischemic strokes, which may lead to adverse patient outcomes. Only a few cases are described in the literature regarding SARS-CoV-2 positive patients developing thrombotic ischemic strokes despite therapeutic anticoagulation. Case Report: The following is a case discussion regarding a 71-year-old female with pas...

High serum complement component C4 as a unique predictor of unfavorable outcomes in diabetic stroke
In this study, the association of serum complement levels with the prognosis of diabetic stroke was examined. Patients with acute ischemic stroke were recruited and were divided into two groups according to their history of diabetes. Baseline data on the admission, including C3 and C4 were collected. Neurologic function at discharge was the primary outcome and was quantified by the National Institutes of Health Stroke Scale (NIHSS). A total of 426 patients with acute ischemic stroke (116 diabetic strokes and 310 non-diabetic strokes) were recruited in this study. There were significant differences between the two groups in...

The Impact of Vascular Risk Factors on Post-stroke Cognitive Impairment: The Nor-COAST Study
Discussion: Our findings indicate that a focal stroke lesion might be related to pathophysiological processes leading to global cognitive impairment. The poorer prognosis of PSCI in patients with vascular risk factors emphasizes the need for further research on complex vascular risk factor interventions to prevent PSCI.

Acute Ischemic Stroke.
Authors: Rossi UG, Ierardi AM, Cariati M Abstract A 77-year-old woman with a history of hypertension developed acute onset of aphasia and right hemiplegia and hemisensory loss. She was urgently referred to emergency department. Cerebral multidetector computed tomographic angiography (MD-CTA) revealed an acute ischemic stroke due to the occlusion of the left middle cerebral artery (Figure 1). Since the symptoms started three hours previously, the patient was candidate for mechanical thrombectomy. The patient then performed a selective digital subtraction angiography (DSA) of the left internal carotid artery that con...

Embolic stroke of undetermined source (ESUS) cohort of Brazilian patients in a university hospital
ABSTRACT Embolic stroke of undetermined source (ESUS) is an important group of cryptogenic strokes that are in evidence due recent ongoing trials. We reviewed medical records at discharge from the stroke unit of all patients who met ESUS criteria and attended our institution between February 2016 and July 2017. Among 550 stroke patients, 51 had ESUS. We found that hypertension (60%), diabetes mellitus (34%), and smoking (36%) were the most prevalent risk factors. The mean National Institutes of Health Stroke Scale (NIHSS) scores were 7 at admission and 4 at discharge, while median scores on the modified Rankin scale were 0...

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...

Effective ADAPT Thrombectomy in a Patient with Acute Stroke due to Cardiac Papillary Elastofibroma: Histological Thrombus Confirmation
A 75-year-old man with hypertension and atrial fibrillation was admitted to our emergency room with right-sided hemiplegia and complete aphasia (National Institutes of Health Stroke Scale [NIHSS] score  = 18). A noncontrast computed tomography scan showed a slight hypodensity in the left insular region and a bright hyperdense sign in the M1 tract of the left middle cerebral artery (MCA). Angio-CT confirmed an occlusion of the M1 tract of the MCA. Magnetic resonance diffusion-weighted imaging/p erfusion-weighted imaging was obtained and revealed a mismatch in the left parietal cortical region.

Factors for short-term outcomes in patients with a minor stroke: results from China National Stroke Registry
In this study, we aimed to identify which factors were associated with adverse outcomes of a minor stroke. Methods: The China National Stroke Registry (CNSR) is a nationwide prospective registry for patients presented to hospitals with acute cerebrovascular events between September 2007 and August 2008. The 3-month follow-up was completed in 4669 patients with a minor stroke defined as the initial neurological severity lower than 4 in the National Institutes of Health Stroke Scale (NIHSS). Multivariate model was used to determine the association between risk factors and clinical outcomes. Results: Of 4669 patients with a m...

Influence of previous physical activity on the outcome of patients treated by thrombolytic therapy for stroke
Abstract Physical activity prevents stroke and is associated with less severe strokes. The neuroprotective effect in patients treated with intravenous (i.v.) recombinant tissue plasminogen activator (rt-PA), remains uncertain. We aimed at evaluating the relationship between previous physical activity and outcomes in stroke patients treated with i.v. rt-PA. OPHELIE-SPORT was a prospective observational multicenter study conducted in French and Japanese stroke patients treated with i.v. rt-PA. We evaluated the presence, weekly duration (<2, 2–5, >5 h) and intensity (light, moderate, heavy) of previous leisu...

Association between polyvascular atherosclerosis and estimated glomerular filtration rate in patients with ischaemic stroke: data analysis of the patients in the Chinese National Stroke Registry.
This study evaluated the prevalence of chronic kidney disease (CKD) in ischemic stroke (IS) patients with polyvascular disease (PolyVD) and analysed the relationship between PolyVD and estimated glomerular filtration rate (eGFR) in IS patients. METHODS: Data from 9152 consecutive IS patients from the China National Stroke Registry were analysed. PolyVD was defined as patients with IS and coronary artery disease (CAD) and/or peripheral arterial disease (PAD). Chronic kidney disease was defined as eGFR < 60 mL/minute/1.73 m(2).The prevalence of CKD in IS patients with PolyVD was calculated. Logistic regression w...

Infarction in the Anterior Choroidal Artery Territory: Clinical Progression and Prognosis Factors
This study was undertaken to describe the still poorly known evolving profile of anterior choroidal artery (AChA) infarctions, identify their prognosis factors, and evaluate responses to intravenous (IV) thrombolysis. During 42 months, we prospectively enrolled patients with an isolated AChA stroke. Clinical and radiologic parameters were compared between patients with or without progression, defined as any clinical worsening. Factors associated with poor outcome (dependence or death) were tested, and IV thrombolysis responses were assessed. For the 100 of 1234 (8.1%) analyzed patients with AChA stroke (predominantly lacu...

Internal Cerebral Vein Asymmetry on Follow-up Brain Computed Tomography after Intravenous Thrombolysis in Acute Anterior Circulation Ischemic Stroke Is Associated with Poor Outcome
Background: Identifying early predictors of functional outcome after acute ischemic stroke (AIS) is important for planning rehabilitation strategies. Internal cerebral veins (ICV) drain deep parts of brain, run parallel to each other, and consistently seen on computed tomography angiography (CTA). Even minor asymmetry in their filling can be identified. We hypothesized that venous drainage would be impaired in patients with acute occlusion of internal carotid artery or middle cerebral artery. Because systemic thrombolysis can alter the vascular findings, we evaluated the relationship between ICV asymmetry on follow-up CTA ...
