Spectrum of neuroimaging findings in COVID-19.
Abstract An outbreak of corona virus disease 2019 (COVID-19) began in China in December 2019, and rapidly spread to become a worldwide pandemic. Neurological complications encountered in hospitalized patients include acute arterial ischemic cerebrovascular stroke, cerebral venous thrombosis, critical illness-associated cerebral microbleeds, hypertensive hemorrhagic posterior reversible encephalopathy, meningoencephalitis/flare up of infections, flare up of multiple sclerosis, acute disseminated encephalomyelitis, cerebral hemodynamic/hypoxic changes such as watershed ischemic changes and hypoxic ischemic encephalo...

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...

Perinatal Arterial Ischemic Stroke in Fetal Vascular Malperfusion: A Case Series and Literature Review PEDIATRICS
SUMMARY: Fetal vascular malperfusion includes a continuum of placental histologic abnormalities increasingly associated with perinatal brain injury, namely arterial ischemic stroke. Here, we describe the clinical-neuroimaging features of 5 neonates with arterial ischemic stroke and histologically proved fetal vascular malperfusion. All infarcts involved the anterior territories and were multiple in 2 patients. In 2 neonates, there were additional signs of marked dural sinus congestion, thrombosis, or both. A mixed pattern of chronic hypoxic-ischemic encephalopathy and acute infarcts was noted in 1 patient at birth. Systemi...

Interventional stroke treatment - Is it also safe for arteries? Looking at thrombectomy wall damage through clot histology.
CONCLUSIONS: The overall risk of arterial vessel wall injury aspiration thrombectomy was low in our study. Aspiration thrombectomy and the procedure related with a retrieving device together with an ischemia time longer than 6 hours may increase the risk of vessel injury through the thrombectomy procedure. Further investigations are necessary to elucidate the influence of the mentioned aspects. PMID: 33269973 [PubMed - as supplied by publisher]

COVID-19-Associated Carotid Atherothrombosis and Stroke EXTRACRANIAL VASCULAR
We present a radiology-pathology case series of 3 patients with coronavirus disease 2019 (COVID-19) with acute ischemic stroke due to fulminant carotid thrombosis overlying mild atherosclerotic plaque and propose a novel stroke mechanism: COVID-associated carotid atherothrombosis.

Deep medullary vein engorgement and superficial medullary vein engorgement: two patterns of perinatal venous stroke
AbstractPerinatal venous stroke has classically been attributed to cerebral sinovenous thrombosis with resultant congestion or thrombosis of the small veins draining the cerebrum. Advances in brain MRI, in particular susceptibility-weighted imaging, have enabled the visualization of the engorged small intracerebral veins, and the spectrum of perinatal venous stroke has expanded to include isolated congestion or thrombosis of the deep medullary veins and the superficial intracerebral veins. Congestion or thrombosis of the deep medullary veins or the superficial intracerebral veins can result in vasogenic edema, cytotoxic ed...

Large Venous Sac Thrombus Formation after Endovascular Embolization of Ruptured Pulmonary Arteriovenous Malformation: Usefulness of Time-Resolved MR Angiography in Decision Making
Pulmonary arteriovenous malformations (PAVMs) are direct connections between the pulmonary artery and vein, which can result in paradoxical embolism causing stroke and brain abscess due to a right-to-left shunt or thin-walled aneurysmal sac rupture (1). Venous sac thrombosis after endovascular feeding artery embolization can migrate to the systemic circulation if residual shunt flow remains despite no abnormality in the pulmonary venous circulation (2,3). The authors observed a partial venous sac thrombus after feeding artery embolization for a ruptured PAVM, and it was challenging to determine whether the patient should u...

Intraluminal Carotid Artery Thrombus in COVID-19: Another Danger of Cytokine Storm? EXTRACRANIAL VASCULAR
We report a series of 6 patients with COVID-19 with acute ischemic stroke due to intraluminal carotid artery thrombus presenting during an 8-day period. Six patients were included (5 men) with a mean age of 65.8 years (range, 55–78 years). COVID-19 was diagnosed by detection of Severe Acute Respiratory Syndrome coronavirus 2 in 5 patients and was presumed due to typical clinical and imaging findings in 1 patient. All patients had vascular risk factors including diabetes (83%), hyperlipidemia (100%), and smoking (17%). Four patients presented with large infarcts with initial NIHSS scores of 24–30. During their h...

Influence of the "distance to thrombus" in acute middle cerebral artery occlusion : A predictor for the clinical outcome after endovascular treatment.
CONCLUSION: DT correlates with the clinical symptoms of patients with acute MCA occlusion. In addition, DT is an independent predictor of the clinical outcome of patients suffering from acute stroke due to MCA occlusion. PMID: 32821966 [PubMed - as supplied by publisher]

Transcranial duplex ultrasound monitoring of intracranial arterial stenosis treated with ELUTAX "3" drug-eluting balloon.
We report the results of transcranial ultrasound monitoring in three patients with intracranial arterial stenosis of the middle cerebral artery treated with the only drug-eluting balloon certificated for intracranial use in highly symptomatic intracranial arterial stenosis, ELUTAX "3" (AR Baltic Medical). We performed transcranial Doppler ultrasounds 24 h, 72 h, 10 days, 15 days and 30 days after the angioplasty, thereby measuring mean flow velocity (MFV) in the maximum stenosis area in patients with symptomatic steno-occlusive disease of the middle cerebral artery treated with ELUTAX "3". Two patients were treated during ...

Association of local anesthesia versus conscious sedation with functional outcome of acute ischemic stroke patients undergoing embolectomy.
CONCLUSION: Functional outcome of acute ischemic stroke patients undergoing embolectomy appears to be similar for patients receiving local anesthesia and conscious sedation. This similarity may be beneficial to a future study comparing general anesthesia to local anesthesia and conscious sedation. The use of local anesthesia or conscious sedation does not significantly impact hemodynamic status. PMID: 32375517 [PubMed - as supplied by publisher]
