Predictive Factors for Early Clinical Improvement after Intra-arterial Thrombolytic Therapy in Acute Ischemic Stroke
This study aimed to identify clinical and radiological variables that are predictive of early improvement (EI) after IAT in acute ischemic stroke.Methods: This single-center retrospective cohort study included 141 consecutive patients who underwent IAT for terminal internal carotid and/or middle cerebral artery (MCA) occlusions. EI was defined as a National Institutes of Health Stroke Scale (NIHSS) score less than 3 or NIHSS score improvement of 8 points or more within 72 hours of IAT. The EI and non-EI groups were compared in terms of clinical and radiological findings before and after IAT.Results: Forty-nine patients sh...

Ischemic Stroke in Evolution: Predictive Value of Perfusion Computed Tomography
Background: Various perfusion computed tomography (PCT) parameters have been used to identify tissue at risk of infarction in the setting of acute stroke. The purpose of this study was to examine predictive value of the PCT parameters commonly used in clinical practice to define ischemic penumbra. The patient selection criterion aimed to exclude the effect of thrombolysis from the imaging data.Methods: Consecutive acute stroke patients were screened and a total of 18 patients who initially underwent PCT and CT angiogram (CTA) on presentation but did not qualify to receive thrombolytic therapy were selected. The PCT images ...

Hyperdense Cerebral Artery Computed Tomography Sign Is Associated with Stroke Severity rather than Stroke Subtype
The hyperdense cerebral artery sign (HCAS) on unenhanced computed tomography (CT) in acute ischemic stroke is a valuable clinical marker, but it remains unclear if HCAS reflects clot composition or stroke etiology. Therefore, variables independently associated with HCAS were identified from a large international data set of patients treated with intravenous thrombolysis.

Predicting Stroke Outcome Using Clinical- versus Imaging-based Scoring System
Several models to predict outcome in ischemic stroke patients receiving intravenous (i.v.) alteplase can be divided into clinical-based and imaging-based systems. Alberta Stroke Program Early Computed Tomography (CT) Score (ASPECTS) and Dense cerebral artery sign/early infarct signs on admission CT scan, prestroke modified Rankin Scale (mRS) score, Age, Glucose level at baseline, Onset-to-treatment time, and baseline National Institutes of Health Stroke Scale score (DRAGON) are typical imaging- and clinical-based scoring systems, respectively.

Cost Burden of Stroke Mimics and Transient Ischemic Attack after Intravenous Tissue Plasminogen Activator Treatment
Treatment decisions for patients with acute stroke symptoms are based on pertinent history, neurologic examination, laboratory studies, and head computed tomography. In this setting, patients with stroke mimic (SM) may mistakenly receive intravenous tissue plasminogen activator (IV-rtPA). The goal of this study was to investigate the excess direct/indirect hospital costs among patients who received IV-rtPA when final diagnosis was not ischemic stroke.

Thrombolysis, Complete Recanalization, Diffusion Reversal, and Luxury Perfusion in Hyperacute Stroke
A 59-year old man was admitted to our stroke care unit 1.8 hours after onset of cardioembolic stroke. Administration of issue-plasminogen activator achieved complete recanalization, and his lesion on diffusion-weighted imaging (DWI) disappeared and single photon emission computed tomography showed luxury perfusion. DWI reversal and luxury perfusion were sometimes observed in hyperacute stroke patients, especially timely reperfusion was achieved. However, the relationships between DWI reversal and luxury perfusion were not well known.

Visual Determination of Conjugate Eye Deviation on Computed Tomography Scan Predicts Diagnosis of Stroke Code Patients
Head computed tomography (CT) is critical for stroke code evaluations and often happens prior to completion of the neurological exam. Eye deviation on neuroimaging (DeyeCOM sign) has utility for predicting stroke diagnosis and correlates with National Institutes of Health Stroke Scale (NIHSS) gaze score. We further assessed the utility of the DeyeCOM sign, without complex caliper-based eye deviation calculations, but simply with a visual determination method.

Long-Term Impact of Implementation of a Stroke Protocol on Door-to-Needle Time in the Administration of Intravenous Tissue Plasminogen Activator
This study aims to evaluate the effectiveness of implementing a stroke protocol (SP) in improving door-to-needle time (DTNT) and door-to-computed tomography (DTCT) time from 2010 to 2014. Published data from the Get With The Guidelines-Stroke (GWTGS) participating hospitals showed that median DTNT = 75 minutes with 26.6% of the patients achieving the recommended DTNT of 60 minutes or less. Implementation of an SP, which specifies the role of nurses, physicians, and technicians during acute stroke evaluation, can improve DTNT.

Differentiating Stroke and Seizure in Acute Setting —Perfusion Computed Tomography?
Perfusion computed tomography (PCT) is part of acute stroke protocol in many hospitals; however, its clinical utility is still being disputed. Beyond its use in core and penumbra estimation, there is also a question about PCT role in stroke mimics diagnosis. Case series or small, retrospective studies showed equivocal results. This is the first published prospective, comparative study on PCT in differentiating stroke and seizure in acute setting.

Reliability and Utility of the Alberta Stroke Program Early Computed Tomography Score in Hyperacute Stroke
The Alberta Stroke Program Early Computed Tomography Score (ASPECTS) on non-contrast computed tomography (NCCT) is dependent on the visibility of early ischemic change. The goal of our study was to evaluate whether time from ischemic stroke onset to initial NCCT influences the inter-rater variability and prognostic accuracy of ASPECTS for a 3-month functional outcome.

Spinal epidural hematoma as a stroke mimic
Spinal epidural hematoma is a rare disease with an annual incidence of 1 per 1,000,000 individuals;1 however, it is a critical stroke mimic.2 As patients with spinal epidural hematoma typically present with acute hemiparesis,3,4 such a presentation is not expected to be detected by a computed tomography (CT) scan of the brain, which is the most common neuroimaging choice in patients with an activated stroke code. Indeed, there are several case reports in which patients with spinal epidural hematoma were misdiagnosed with ischemic stroke and treated with anti-thrombotic therapy, including intravenous thrombolysis,5 –10 oc...

Diagnostic and Prognostic Blood Biomarkers in Transient Ischemic Attack and Minor Ischemic Stroke: An Up-To-Date Narrative Review
Transient ischemic attack (TIA) is a brief episode of focal neurological deficit, lasting less than 24 hours, and reaching its climax usually within minutes. Patients with an even tiny ischemic brain lesion on imaging are considered, on tissue-based criteria, to have a minor ischemic stroke (MIS), usually with mild and non-disabling symptoms.1 Although a consensus clinical definition for MIS is currently lacking, 5 working definitions based on information from head computed tomography (CT) scan and clinical examination have been developed by the National Institute of Neurological Disorder and Stroke (NINDS) rt-PA stroke study Investigators.
