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.

Accuracy of Stroke Diagnosis in Telestroke-Guided Tissue Plasminogen Activator Patients
The objective of the study is to assess the accuracy of final diagnosis in telestroke-guided tissue plasminogen activator (rt-PA) patients compared with bedside evaluation using computed tomography (CT) or magnetic resonance imaging (MRI) as a surrogate for final stroke diagnosis. The overall goal was to determine if telestroke had similar diagnostic accuracy as bedside evaluations in diagnosing rt-PA-treated patients.

High Extent of Intracranial Carotid Artery Calcification Is Associated with Downstream Microemboli in Stroke Patients
Intracranial arterial calcification (ICAC) is frequently detected on head computed tomography and has been found to be associated with ischemic stroke by recent clinical studies.

Utility of Repeat Cerebrovascular Imaging among Hospitalized Stroke Patients
The purpose of this study is to evaluate the frequency and clinical utility of repeat cerebrovascular imaging with computed tomography angiography (CTA) of the head after contrast-enhanced magnetic resonance angiography (CE-MRA) of the head in acute stroke patients.

Different Perfusion Patterns in a Patient with Acute Ischemic Stroke
A 29-year-old male patient with aphasia and mild weakness of the right arm arrived at the emergency room 4 hours after symptom onset. The computed tomography perfusion showed a typical delay in the time-based maps in the left occipital lobe and another hyperperfused area in the left frontal lobe. The follow-up magnetic resonance imaging confirmed cortical ischemic lesions in both areas. This case shows that besides hypoperfusion, hyperperfusion can also be found in the first stages of acute stroke, and it is highly suggestive of established ischemic lesions.

18F-Fluoride and 18F-Fluorodeoxyglucose Positron Emission Tomography After Transient Ischemic Attack or Minor Ischemic Stroke: Case-Control Study Molecular Imaging
Conclusions— 18F-Fluoride PET/CT highlights culprit and phenotypically high-risk carotid plaque. This has the potential to improve risk stratification and selection of patients who may benefit from intervention.

An Acute Ischemic Stroke Resulting from Aortic Dissection
A 39-year-old man with syncope and persistent dizziness was sent to stroke emergency. Patient's diffusion magnetic resonance imaging of brain showed acute ischemia in right cerebella and right occipital lobe, thus intravenous recombinant tissue plasminogen activator was given to him. However, the patient behaved rather restless with repeated complaint of back and thoracic pain. Further thorax computed tomography angiography confirmed that the underlying cause turned out to be aortic dissection.

Histology of Thrombectomy Specimen Reveals Cardiac Tumor Embolus in Cryptogenic Young Stroke
A 25-year-old woman presented with acute onset of right hemiplegia and global aphasia with National Institutes of Health Stroke Scale score of 19. Computed tomography angiography demonstrated occlusion of the left proximal middle cerebral artery. She was thrombolysed with intravenous recombinant tissue plasminogen activator (0.6  mg/kg) within 3 hours of onset of symptoms and was taken up for mechanical thrombectomy. The retrieved specimen appeared pale white and soft; histopathologic examination revealed a papillary neoplasm composed of papillae with hyalinized cores lined by endothelium, consistent with papillary fibro...

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...

Early Triage of Cardioembolic Sources Using Chest Spectral Computed Tomography in Acute Ischemic Stroke
The present study investigated the potential usefulness of delayed-phase, low-dose, non-gated, chest spectral CT scans (DSCT) for the early triage of cardioembolic (CE) sources in patients admitted with acute ischemic stroke (AIS), and for the simultaneous detection of myocardial disease and thrombotic complications.

Stroke Dysbiosis Index (SDI) in Gut Microbiome Are Associated With Brain Injury and Prognosis of Stroke
Conclusions: We developed an index to measure gut microbiota dysbiosis in stroke patients; this index was significantly correlated with patients' outcome and was causally related to outcome in a mouse model of stroke. Our model facilitates the potential clinical application of gut microbiota data in stroke and adds quantitative evidence linking the gut microbiota to stroke. Introduction Ischemic stroke imposes a heavy burden on society, with 24.9 million cases worldwide (1). Although intravenous thrombolysis and endovascular treatment greatly improve some patients' prognosis, the prognosis for most pa...
