Predictors of Reperfusion in Patients with Acute Ischemic Stroke BRAIN
CONCLUSIONS: Recanalization and reperfusion are strongly associated but not always equivalent in ischemic stroke. A smaller total ischemic area is the only independent predictor of complete reperfusion.

COVID-19 Severity and Stroke: Correlation of Imaging and Laboratory Markers ADULT BRAIN
CONCLUSIONS: Patients with stroke hospitalized with severe COVID-19 are characterized by higher inflammatory, coagulopathy, and tissue-damage biomarkers, supporting proposed pathogenic mechanisms of hyperinflammation activating a prothrombotic state. Cautious balancing of thrombosis and the risk of hemorrhagic transformation is warranted when considering anticoagulation.

Duplex Sonographic Diagnosis of Perinatal Hemorrhagic Stroke.
Abstract Children are particularly at risk for stroke in the neonatal period. Neonatal hemorrhagic stroke is rarer than ischemic stroke. The incidence is 40.7/100 000 live births. Hemorrhagic stroke is caused by a disruption in venous drainage usually due to local thrombosis. As a result of the nonspecific clinical symptoms in this age group, diagnosis is usually made too late. The only relatively specific symptom is a cerebral seizure during the first week of life. Therefore, stroke should be ruled out by diagnostic imaging in the case of any seizure in the first days of life. The diagnostic method of choice is...

Characteristics of Large-Vessel Occlusion Associated with COVID-19 and Ischemic Stroke INTERVENTIONAL
SUMMARY: The mechanisms and phenotype of ischemic stroke associated with coronavirus disease 2019 (COVID-19) remain uncertain. A retrospective study was conducted in patients with COVID-19 presenting with ischemic stroke from March 1 to May 25, 2020, and cases with large-vessel occlusion were identified. To provide baseline institutional stroke data within and outside the COVID-19 pandemic, all consecutive ischemic stroke and TIA admissions (COVID and non-COVID) to the hospital during a 10-week period from March 1 to May 10, 2020, were collected and compared with data from the same time period in 2019. Among 20 patients wi...

Correlation between clot density and recanalization success or stroke etiology in acute ischemic stroke patients.
Conclusions There was no relationship between clot density and revascularization success or stroke etiology in our study. More research is needed to determine if clot density can predict recanalization rates or indicate etiology. PMID: 28604188 [PubMed - in process]

Sonographic and Doppler Sonographic Diagnosis of  Neonatal Ischemic Stroke.
Sonographic and Doppler Sonographic Diagnosis of Neonatal Ischemic Stroke. Ultraschall Med. 2017 Jul 13;: Authors: Deeg KH Abstract Children are particularly at risk for stroke in the neonatal period. 1/3 of all strokes in children occur during the perinatal period. The incidence of perinatal stroke is 1:4000. A differentiation is made between ischemic stroke and hemorrhagic stroke. Ischemic strokes are caused by arterial occlusion due to thrombosis or embolism. As a result of the nonspecific clinical symptoms in this age group, diagnosis is usually made too late. The only relatively specific symptom...

The incidence of stroke in patients with early echocardiography after acute myocardial infarction
AbstractLeft ventricular (LV) thrombus formation after ST-elevation myocardial infarction (STEMI) increases the risk of stroke. In our center, most echocardiograms are performed within 2  days post-STEMI. However, LV thrombi often become visible later. We assessed the 1-year incidence of stroke in patients without LV thrombus on echocardiography performed early (1–2 days) vs. later (day ≥ 3) post-STEMI. This retrospective observational study included 416 patients with acut e STEMI. Patients with atrial fibrillation were excluded. All patients underwent echocardiography during admission. Patients with stroke withi...

Impact of Implementing Cardiac CT in Evaluating Patients Suspected of Cardioembolic Stroke
Conclusions: Implementing cardiac CT in assessing patients suspected of cardioembolic stroke added value to echocardiographic evaluation, by detecting major embolic potential findings. In addition, cardiac CT revealed additional potentially significant stroke-unrelated findings and CAD.

Worldwide Analysis of Radiology Access and Education for Stroke Care: View From Abroad From 14 Countries
The World Health Organization reports that stroke is among the leading causes of death in noncommunicable diseases worldwide despite advances in acute stroke care [1]. Early interventions in cerebrovascular accidents can prevent mortality and minimize debilitating effects of stroke. There have been major recent advancements in stroke care to intervene more quickly and effectively. We are entering a new era of stroke imaging-based treatment for late acute ischemic stroke. Recent neurointerventional trials, such as DAWN and DEFUSE 3, have transformed the way clinicians provide acute stroke care in the United States and provi...

Is Histologic Thrombus Composition in Acute Stroke Linked to Stroke Etiology or to Interventional Parameters? INTERVENTIONAL
CONCLUSIONS: We interpreted the higher macrophage and platelet content in cardioembolic thrombi compared with large-artery atherosclerotic stenosis or embolic stroke of undetermined source thrombi as an indication that the latter type might be derived from an atherosclerotic plaque rather than from an undetermined cardiac source. The extent of thrombus fragmentation was associated with a more challenging mechanical thrombectomy and a higher lymphocyte content of the thrombi. Thus, thrombus fragmentation not only might be caused by the recanalization procedure but also might be a feature of a lymphocyte-rich, difficult-to-r...

Mechanical Thrombectomy for Acute Ischemic Stroke: A Case Study Using the Penumbra Stroke System
Abstract: Over recent years, there have been dramatic advances in the ability to treat an acute ischemic stroke. Thrombolysis with intravenous recombinant tissue plasminogen activator can now be performed up to 4.5 hr after stroke onset in certain circumstances, and new mechanical thrombectomy devices allow intervention up to and beyond 8 hr in some instances. The Penumbra Stroke System (Penumbra Inc., Alameda, CA), one of these mechanical thrombectomy devices, uses a series of catheters to aspirate thrombus from occluded cerebral arteries and thus restore flow to the adjacent ischemic brain.This case study highlights the ...

MRI characteristics of carotid bulb atypical fibromuscular dysplasia in black stroke patients
Conclusions aFMD generates a particular MRI pattern in our four patients, which could increase the diagnosis accuracy. Carotid bulb lesion in black stroke patients should suggest aFMD and MRI analysis may contribute to rule out differential diagnoses.

Mimics of Acute Stroke: Tips and Tricks for Solving the Diagnostic Dilemma
Stroke affects approximately 800,000 people in the United States each year and is the fourth major leading cause of adult mortality.1 Rapid diagnostic evaluation and prompt treatment are important to prevent death and disability from a stroke. The literature suggests that up to 30% of patients who present with acute onset of neurologic symptoms were found to have a stroke misdiagnosis. In addition, the safety of thrombolytic therapy for stroke mimics has not been fully studied. Although patients with acute stroke can benefit substantially from thrombolytic therapy, misdiagnosis of acute stroke can carry serious implication...

Susceptibility-diffusion mismatch in middle cerebral artery territory acute ischemic stroke: clinical and imaging implications.
CONCLUSION: The presence of SWI-DWI mismatch in acute MCA territory ischemic infarct is associated with smaller infarct volume. Moreover, SWI-DWI mismatch was associated with better outcome after correction for infarct size, severity of admission symptoms, and age. PMID: 27799573 [PubMed - as supplied by publisher]
