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. We present a pediatric patient who underwent endovascular therapy for an internal carotid artery occlusion related acute ischemic stroke in the setting of active COVID-19 and had an excellent outcome thanks to a streamlined stroke pathway involving the vascular neurology, neuro-interventional, neurocritical care, and anesthesiology teams.

Owing to systemic inflammation and widespread vessel endotheliopathy, SARS-CoV-2 has been shown to confer an increased risk of cryptogenic stroke, particularly in patients without any traditional risk factors. In this report, we present a case of a 67-year-old female who presented with acute stroke from bilateral anterior circulation large vessel occlusions, and was incidentally found to be COVID-positive on routine hospital admission screening. The patient had a large area of penumbra bilaterally, and the decision was made to pursue bilateral simultaneous thrombectomy, with two endovascular neurosurgeons working on each side to achieve a faster time to recanalization. Our study highlights the utility and efficacy of simultaneous bilateral thrombectomy, and this treatment paradigm should be considered for use in patients who present with multifocal large vessel occlusions.

OBJECTIVES: Infection with the SARS-COV2 virus (COVID-19) may be complicated by thrombotic diathesis. This complication often involves the pulmonary microcirculation. While macrovascular thrombotic complications of the lung may include pulmonary artery embolism, pulmonary artery thrombus in situ has also been hypothesized. Pulmonary vein thrombosis has not been described in this context. METHODS/RESULTS: Herein, we provide a case of an otherwise healthy male who developed an ischemic stroke with left internal carotid thrombus. Further imaging revealed pulmonary emboli with propagation through the pulmonary veins into the left atrium. This left atrial thrombus provides a source of atypical "paradoxic arterial embolism". CONCLUSIONS: Thrombotic outcomes in the setting of severe COVID 19 pneumonia may include macrovascular venous thromboembolism, microvascular pulmonary vascular thrombosis and arterial thromboembolism. Pulmonary vein, herein described, provides further mechanistic pathway for potential arterial embolic phenomenon.

CASE DESCRIPTION: 37-year-old female with PCR-RT swab for COVID-19 positive, with neurological manifestation as a result of internal carotid artery occlusion. CLINICAL FINDINGS: Nasal congestion and sneezing of 5 days duration; pulsatile headache in the left hemicranium 3 days prior to admission, with intensity 6/10 according to the visual analogue scale, accompanied by phosphenes, photophobia and diplopia; with subsequent developing right hemiparesis over a 26-hour period. TREATMENT AND RESULT: She was given medical management with oral antiplatelet agents and anticoagulants (subcutaneous and oral) during his hospitalization, it was not possible to perform thrombolysis and thrombectomy due to the high risk of complications. He was discharged at 14 days, without functional limitation, symmetrical strength in upper and lower limbs, bilateral visual acuity 20/20, denying headache. CLINICAL RELEVANCE: The case presented here describes a pattern in how data supporting an association between COVID-19 and stroke in young populations with or without typical vascular risk factors, sometimes with only mild respiratory symptoms, is increasing. Prospective studies are required to further evaluate this association, as well as anticoagulation studies to prevent these potentially life-threatening events.

DESCRIPCIÓN DEL CASO: Mujer de 37 años con hisopado PCR-RT para COVID-19 positivo, con manifestación neurológica por oclusión de la arteria carótida interna. HALLAZGOS CLÍNICOS: Congestión nasal y estornudos de 5 días de duración; cefalea pulsátil en hemicráneo izquierdo 3 días antes del ingreso, con intensidad 6/10 según la escala visual analógica, acompañada de fosfenos, fotofobia y diplopía; con posterior desarrollo de hemiparesia derecha durante un período de 26 horas. TRATAMIENTO Y RESULTADO: Se le brindó manejo médico con antiagregantes plaquetarios orales y anticoagulantes (subcutáneos y orales) durante su internación, no fue posible realizar trombólisis y trombectomía por alto riesgo de complicaciones. Fue dado de alta a los 14 días, sin limitación funcional, fuerza simétrica en miembros superiores e inferiores, agudeza visual bilateral 20/20, negando cefalea. RELEVANCIA CLÍNICA: Se describe un patrón que indica cómo están aumentando los datos que apoyan una asociación entre COVID-19 y el accidente cerebrovascular en poblaciones jóvenes con o sin factores de riesgo vascular típicos, a veces con solo síntomas respiratorios leves. Se requieren estudios prospectivos para evaluar más a fondo esta asociación, así como estudios de anticoagulación para prevenir estos eventos potencialmente mortales.
