Successful Endovascular Therapy in COVID-19 Associated Pediatric Ischemic Stroke.

Cerebrovascular diseases attributed to coronavirus disease 2019 (COVID-19) are uncommon but can result in devastating outcomes. Pediatric acute ischemic strokes are themselves rare and with very few large vessel occlusion related acute ischemic strokes attributed to COVID-19 described in the literature as of date. COVID-19 pandemic has contributed to acute stroke care delays across the world and with pediatric endovascular therapy still in its infancy, it poses a great challenge in facilitating good outcomes in children presenting with acute ischemic strokes in the setting of COVID-19.

Delays in thrombolysis during COVID-19 are associated with worse neurological outcomes: the Society of Vascular and Interventional Neurology Multicenter Collaboration.

Introduction: We have demonstrated in a multicenter cohort that the COVID-19 pandemic has led to a delay in intravenous thrombolysis (IVT) among stroke patients. Whether this delay contributes to meaningful short-term outcome differences in these patients warranted further exploration.

Methods: We conducted a nested observational cohort study of adult acute ischemic stroke patients receiving IVT from 9 comprehensive stroke centers across 7 U.

Cardio-Cerebral Infarction, Free-Floating Thrombosis and Hyperperfusion in COVID-19.

Cardio-cerebral infarction, which refers to an acute ischemic stroke (AIS) and acute myocardial infarction (AMI) that occur concurrently, is an uncommon phenomenon with a grave prognosis. Intraluminal carotid thrombus (ICT) is an infrequently encountered cause of ischemic stroke and can be associated with an underlying hypercoagulable state. One severe yet prevalent complication of infection with Coronavirus Disease 2019 (COVID-19) is thrombosis from multi-pathway inflammatory responses.

Lack of Reperfusion Rather Than Number of Passes Defines Futility in Stroke Thrombectomy: A Matched Case-Control Study.

Background And Purpose: There is a robust relationship between the duration of ischemia and functional outcomes after mechanical thrombectomy. Higher number of mechanical thrombectomy passes strongly correlate with lower chances of favorable outcomes. Indeed, previous studies have suggested that after multiple passes the procedure may be futile.

Intraluminal carotid thrombosis and acute ischemic stroke associated with COVID-19.

COVID-19 (Coronavirus disease 2019) caused by SARS-CoV-2 has a diverse constellation of neurological manifestations that include encephalopathy, stroke, Guillain-Barré syndrome, myelitis, and encephalitis. Intraluminal carotid thrombi (ILT) are infrequent lesions seen in only 1.6% of patients with acute ischemic stroke.

Cerebral Venous Sinus Thrombosis in COVID-19 Patients: A Multicenter Study and Review of Literature.

Background: COVID-19 infection has been known to predispose patients to both arterial and venous thromboembolic events such as deep venous thrombosis, pulmonary embolism, myocardial infarction, and stroke. A few reports from the literature suggest that Cerebral Venous Sinus Thrombosis (CVSTs) may be a direct complication of COVID-19.

Objective: To review the clinical and radiological presentation of COVID-19 positive patients diagnosed with CVST.
