Tick-borne Encephalitis: Stroke-like Presentation
We report a unique case of clinical symptoms and radiological findings compatible with a stroke-like inflammatory lesion in the thalamus, suggesting microangiopathy from TBEV. Our case shows that TBEV could be a possible cause of stroke-like lesions.

Impaired Collateral Flow in Pial Arterioles of Aged Rats During Ischemic Stroke
AbstractCerebral collateral circulation and age are critical factors in determining outcome from acute ischemic stroke. Aging may lead to rarefaction of cerebral collaterals, and thereby accelerate ischemic injury by reducing penumbral blood flow. Dynamic changes in pial collaterals after onset of cerebral ischemia may vary with age but have not been extensively studied. Here, laser speckle contrast imaging (LSCI) and two-photon laser scanning microscopy (TPLSM) were combined to monitor cerebral pial collaterals between the anterior cerebral artery (ACA) and the middle cerebral artery (MCA) in young adult and aged male Spr...

Integration of Real-Time Electronic Health Records and Wireless Technology in a Mobile Stroke Unit
Background: UCHealth's Mobile Stroke Unit (MSU) at University of Colorado Hospital is an ambulance equipped with a computed tomography (CT) scanner and tele-stroke capabilities that began clinical operation in Aurora, Colorado January 2016. As one of the first MSU's in the United States, it was necessary to design unique and dynamic information technology infrastructure. This includes high-speed cellular connectivity, Health Insurance Portability and Accountability Act compliance, cloud-based and remote access to electronic medical records (EMR), and reliable and rapid image transfer.

Preprocedure Intravenous Recombinant Tissue Plasminogen Activator and Risk of Distal Embolization with Thrombectomy in Acute Ischemic Stroke
Background: Intravenous recombinant tissue plasminogen activator (IV rt-PA) prior to thrombectomy may reduce the risk of intraprocedural distal embolization in acute ischemic stroke patients. Methods: We analyzed the diffusion-weighted imaging acquired with 1.5- or 3-T magnetic resonance imaging (MRI) scans obtained within 24 hours of thrombectomy in consecutive acute ischemic stroke patients. An independent physician identified distal embolization, defined as discrete foci of restricted diffusion independent of the primary area of infarction on MRI scan.

Is Door-to-Needle Time Reduced for Emergency Medical Services Transported Stroke Patients Routed Directly to the Computed Tomography Scanner on Emergency Department Arrival?
A nationally recommended practice to accelerate thrombolytic therapy for acute ischemic stroke is to route emergency medical services (EMS)-transported stroke patients directly to the computed tomography (CT) scanner on arrival. We evaluated door-to-needle time with direct-to-CT routing versus emergency department (ED)-bed first routing.

Predictors of Lesion Cavitation After Recent Small Subcortical Stroke
AbstractMorphologic evolution of recent small subcortical infarcts (RSSI) ranges from lesion disappearance to lacune formation and the reasons for this variability are still poorly understood. We hypothesized that diffusion tensor imaging (DTI) and blood-brain-barrier (BBB) abnormalities early on can predict tissue damage 1  year after an RSSI. We studied prospectively recruited patients with a symptomatic MRI-defined RSSI who underwent baseline and two pre-specified MRI examinations at 1–3-month and 1-year post-stroke. We defined the extent of long-term tissue destruction, termedcavitation index, as the ratio of the 1-...

Sleep Apnea and Early Neurological Deterioration in Acute Ischemic Stroke
Evidence of an association between sleep apnea (SA) and early neurological deterioration (END) in acute phase ischemic stroke is scant. We investigated the prevalence of SA and the impact of SA severity on END in acute ischemic stroke (AIS) patients.

Hemichorea as Presentation of Acute Cortical Ischemic Stroke. Case Series and Review of the Literature
We report 4 cases of acute ischemic cortical strokes presenting as hemichorea, with the infarction being limited to the parietal and insular cortex in perfusion computed tomography scans and magnetic resonance imaging.

D-dimer and Body CT to Identify Occult Malignancy in Acute Ischemic Stroke
Patients with acute ischemic stroke associated with cancer have D-dimer elevations greater than those with acute ischemic stroke or cancer alone. While D-dimer has been proposed as a screening tool to identify such patients, its use in clinical practice to identify malignancy and to inform the use of CT scanning has not been well characterized.

Stroke Knowledge in the EstEPA Project, a Population-Based Study
Stroke knowledge is poor in the general population worldwide. Yet, data from Spanish-Speaking populations, particularly in Latin America, are scant. We aim to evaluate stroke awareness using personal interviews in a population-based study.

Bilateral large vessel occlusion causing massive ischemic stroke in a covid-19 patient
The case of a 70-year-old male presenting an ischemic stroke related to COVID-19 infection is described. He was initially admitted to the hospital with respiratory insufficiency syndrome secondary to pneumonia caused by SARS Co2. In the next days, he developed rapid neurological deterioration characterized by drowsiness which progressed to deep coma. D-dimer was elevated. Brain CT scan showed bilateral massive ischemic stroke located in the anterior circulation, CT angiogram showed occlusion in the left internal carotid artery and the right middle cerebral artery.

Alberta Stroke Program Early CT Score and collateral status predict target mismatch in large vessel occlusion with delayed time windows
Conclusions NCCT ASPECTS had a strong correlation with CTP core volumes in patients with LVO-AIS in delayed time windows. Combining NCCT ASPECTS with sCTA-CS resulted in a more accurate prediction of target mismatch. If a CTP scan is not available, NCCT ASPECTS combined with sCTA-CS may guide clinicians in making treatment decisions.

Intravenous Tissue Plasminogen Activator Therapy for an Acute Ischemic Stroke Patient with Later Diagnosed Unilateral Moyamoya Syndrome
We report the use of intravenous tissue plasminogen activator (t-PA) therapy in a 38-year-old patient who was later diagnosed with unilateral moyamoya syndrome. The patient had a sudden onset of unconsciousness, vomiting, dysarthria, and tetraparesis. A neurologic examination revealed consciousness disturbance, right central facial nerve palsy, dysarthria, and tetraparesis with bilateral exotropia and horizontal gaze palsy. A magnetic resonance imaging scan on admission did not reveal fresh cerebral infarction or hemorrhage, but magnetic resonance angiography revealed severe stenosis at the terminal portion of left interna...

MRI in acute cerebral ischemia of the young: The Stroke in Young Fabry Patients (sifap1) Study
Conclusions: Young adults show a high frequency of preexisting and clinically silent infarcts and a relative preference for acute ischemia in the posterior circulation. Findings suggesting small-vessel disease become apparent at age 45 years and older.

5-Fluorouracil–induced Leukoencephalopathy with Acute Stroke-like Presentation Fulfilling Criteria for Recombinant Tissue Plasminogen Activator Therapy
A 61-year-old man underwent systemic chemotherapy with intravenous infusion of nedaplatin and 5-fluorouracil. On the day after the final drug administration, he suddenly experienced difficulty in speaking followed by left-sided weakness. His National Institutes of Health Stroke Scale score was 12. A computed tomographic scan of the brain performed 4 hours after symptom onset revealed no abnormalities. Because all eligibility criteria were fulfilled, he immediately underwent intravenous recombinant tissue plasminogen activator therapy. He recovered from neurologic complications on day 14. An initial magnetic resonance imagi...
