Radiological Eye Deviation as a Predictor of Large Vessel Occlusion in Acute Ischaemic Stroke
This study sought to determine if radiological eye deviation was associated with LVO. Methods: All AIS patients given intravenous thrombolysis who had acute CTA performed in 2 stroke units were reviewed over 2013-2015 for the presence of LVO.

The Yield of Multimodal Computed Tomography among Emergency Department Patients with Suspected Large Vessel Occlusion Stroke
Objectives: Endovascular therapy (EVT) improves outcomes for appropriately selected acute ischemic stroke patients. Guidelines suggest rapid acquisition of noninvasive vascular imaging to screen suspected ischemic stroke patients for large vessel occlusion (LVO) and candidacy for EVT. We sought to quantify the yield of an LVO stroke screening process in an undifferentiated emergency department (ED) suspected stroke population as well as identify predictors of successful EVT. Methods: We identified a cohort of consecutive ED patients who received CT angiography and brain perfusion (CTA/P) imaging to determine candidacy for EVT during 2016.

Diversity of Stroke Presentation in CADASIL: Study from Patients Harboring the Predominant NOTCH3 Mutation R544C
This study investigated the clinical stroke presentation and cranial magnetic resonance imaging (MRI) findings in a group of patients with CADASIL. We reviewed the clinical stroke presentation and brain MRI findings in 73 consecutive Korean patients aged>18 years diagnosed with CADASIL between May 2004 and April 2009. Brain MRI images were also scored for lacunar infarction and cerebral microbleeds. Intracranial atherosclerosis (ICAS) was assessed by magnetic resonance angiography. Disability was measured with the modified Rankin scale (mRS) and classified as good (mRS score 0-2) or poor (mRS score 3-5). In this study, 65 ...

Determinants of Neurologic Deterioration and Stroke-Free Survival After Spontaneous Cervicocranial Dissections: A Multicenter Study
Patients with spontaneous cervicocranial dissection (SCCD) may experience new or recurrent ischemic events despite antiplatelet or anticoagulant therapy. Treatment with stent placement is an available option; however, the literature on patient selection is limited. Thus, identifying patients at high risk for neurologic deterioration after SCCD is of critical importance. The present study examined the rate of neurologic deterioration in medically treated patients with SCCD and evaluated demographic, clinical, and radiologic factors affecting this deterioration. We retrospectively identified consecutive patients with SCCD ov...

Combination of Noninvasive Neurovascular Imaging Modalities in Stroke Patients: Patterns of Use and Impact on Need for Digital Subtraction Angiography
Conclusions: In our experience, a combination of CTA and MRA was frequently used in patients in whom the initial noninvasive imaging was determined insufficient. The combination of findings from CTA and MRA were considered adequate in a large portion of patients resulting in a lower requirement for DSA and higher treatment impact from DSA.

Intra-arterial Thrombectomy versus Standard Intravenous Thrombolysis in Patients with Anterior Circulation Stroke Caused by Intracranial Arterial Occlusions: A Single-center Experience
Background: Severely impaired patients with persisting intracranial occlusion despite standard treatment with intravenous (IV) administration of recombinant tissue plasminogen activator (rtPA) or presenting beyond the therapeutic window for IV rtPA may be candidates for interventional neurothrombectomy (NT). The safety and efficacy of NT by the Penumbra System (PS) were compared with standard IV rtPA treatment in patients with severe acute ischemic stroke (AIS) caused by large intracranial vessel occlusion in the anterior circulation.Methods: Consecutive AIS patients underwent a predefined treatment algorithm based on arri...

Impact of Window Setting Optimization on Accuracy of Computed Tomography and Computed Tomography Angiography Source Image-based Alberta Stroke Program Early Computed Tomography Score
This study analyzed the effect of optimization of window settings on the accuracy of Alberta Stroke Program Early Computed Tomography Score (ASPECTS) performed on noncontrast CT (NCCT) and CT angiography source images (CTA-SI). ASPECTS was calculated on NCCT and CTA-SI with standard and optimized window width/center settings in a consecutive series of patients with acute ishcemic stroke. The difference between CT-based ASPECTS and ASPECTS performed on follow-up magnetic resonance imaging (MRI) were calculated to determine the disparity between initial estimates of the extent of ischemia on CT and follow-up lesion imaging b...

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 ...

Repeated Episodes of Ischemic Stroke over a Short Period in a Patient with Essential Thrombocythemia on Anticoagulant Therapy
A 69-year-old man who had essential thrombocythemia, for which he was taking no medications, suddenly developed aphasia and right hemiplegia and was admitted to the hospital. He was thought to have had an embolic stroke and was initially treated with warfarin. Although the international normalized ratio was in the therapeutic range, he had 3 additional ischemic stroke episodes with the same symptoms after the index stroke. Magnetic resonance angiographic examinations revealed serial changes in middle cerebral artery stenosis. After administration of an antiplatelet agent and hydroxyurea, he had no additional strokes.

Fatal Multiple Systemic Emboli after Intravenous Thrombolysis for Cardioembolic Stroke
Our objective is to present a case of fatal multiple systemic emboli after intravenous thrombolysis for cardioembolic stroke. A 64-year-old woman with atrial fibrillation was admitted for evaluation of sudden consciousness disturbance, right hemiplegia, and aphasia. Diffusion-weighted imaging showed no early ischemic changes of the brain, and magnetic resonance angiography (MRA) showed occlusion of the left middle cerebral artery (MCA). One hour after initiation of 0.6 mg/kg of intravenous alteplase, the MCA was partially recanalized. Her symptoms disappeared the following day. We began intravenous heparin for secondary pr...

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 ...

Early and Continuous Neurologic Improvements after Intravenous Thrombolysis Are Strong Predictors of Favorable Long-term Outcomes in Acute Ischemic Stroke
Background: Intravenously administered tissue plasminogen activator (IV tPA) remains the only approved therapeutic agent for arterial recanalization in acute ischemic stroke (AIS). Considerable proportion of AIS patients demonstrate changes in their neurologic status within the first 24 hours of intravenous thrombolysis with IV tPA. However, there are little available data on the course of clinical recovery in subacute 2- to 24-hour window and its impact. We evaluated whether neurologic improvement at 2 and 24 hours after IV tPA bolus can predict functional outcomes in AIS patients at 3 months.Methods: Data for consecutive...

Clinical Use of Computed Tomographic Perfusion for the Diagnosis and Prediction of Lesion Growth in Acute Ischemic Stroke
Conclusions: In real-world use, acute imaging with CTP did not predict stroke or DWI lesions with sufficient accuracy. Our findings argue against the use of CTP for screening AIS patients until real-world implementations match the accuracy reported from specialized research centers.
