ABSTRACT

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.

ABSTRACT

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. The deterioration of the patient continued and he subsequently died. Large vessel occlusion has been reported in COVID-19 patients, but this clinical presentation is usually unilateral. Cases of bilateral occlusion of large vessels have not been previously reported in COVID-19 patients. This report shows that bilateral massive stroke may occur in COVID-19 cases and it should be suspected in patients who show rapid neurological deterioration without focal deficits.

ABSTRACT

OBJECTIVE: To report six consecutive patients with confirmed coronavirus disease-2019 (COVID-19) who underwent Transcranial Doppler (TCD) ultrasonography evaluation for cerebral microemboli in the setting of suspected or confirmed acute ischemic stroke. METHODS: Patient data were obtained from medical records from Northwestern Memorial Hospital, Chicago, IL between May and June 2020. All patients with confirmed COVID-19 who underwent clinical TCD ultrasonography for microemboli detection were included. RESULTS: A total of eight TCD studies were performed in six patients with COVID-19 (4 men and 2 women, median age 65±5), four with confirmed ischemic stroke and two with refractory encephalopathy. Microemboli were detected in three male patients, two patients had suffered a confirmed ischemic stroke and one who developed prolonged encephalopathy. Microemboli of varying intensity were identified in multiple vascular territories in two patients, and microemboli persisted despite therapeutic anticoagulation in a third patient. Of the three patients without evidence of microemboli on TCD ultrasonography, two patients had suffered a confirmed ischemic stroke, while one remained with refractory encephalopathy. CONCLUSIONS: TCD ultrasonography for microemboli detection identified three patients with confirmed COVID-19 with evidence of cerebral arterial microemboli, including one who was therapeutically anticoagulated. TCD ultrasonography provides a non-invasive method for evaluating cerebral microemboli in patients with COVID-19 and may be useful in assessing response to treatment in cases with suspected or confirmed disorders of hypercoagulability. Further studies investigating the prevalence of cerebral microemboli and associated risk factors are needed to characterize their pathogenic mechanism and guide therapeutic interventions in hospitalized COVID-19 patients.

ABSTRACT

BACKGROUND: The occurrence of large-vessel occlusion in young patients with coronavirus disease 2019 (COVID-19) infection has been exceedingly rare. An extensive review of reported studies revealed a few reported cases. In the present report, we have described the clinical presentation, radiological findings, and outcome of large-vessel occlusion in a young patient with COVID-19 and reviewed the pertinent reported data on this condition. CASE DESCRIPTION: A 31-year-old woman was in her usual state of health until she had presented with a 3-day history of right-sided weakness, slurred speech, and decreased vision. The patient had been taken to several hospitals where she had been treated conservatively with analgesics and discharged. Shortly thereafter, her weakness had become progressive. She had become severely dysarthric and unresponsive. On arrival to the emergency department, her physical examination revealed that she was stuporous, with a Glasgow coma scale of 10 (eye response, 3; verbal response, 2; motor response, 5). The National Institutes of Health Stroke Scale score was 19 on presentation. Brain computed tomography and computed tomography venography revealed an occluded left internal carotid artery and left middle cerebral artery with subacute left middle cerebral artery territory infarction and midline shift. Computed tomography angiography revealed complete occlusion of the left common carotid artery. An emergent decompressive craniectomy was successfully performed. The patient was shifted to the intensive care unit. She was later found to be positive for COVID-19. CONCLUSIONS: Although rare, patients with COVID-19 can present with large-vessel occlusion. Prompt identification of COVID-19-related coagulopathy is essential to assess young patients with clinical manifestations of infarction.

ABSTRACT

In this report, we describe the case of a 5-year-old male with SARS-CoV-2 associated MIS-C with progressive respiratory failure and vasoplegic shock requiring extracorporeal support. At presentation, reverse transcription-polymerase chain reaction (RT-PCR) testing for SARS-CoV-2 was negative, however, SARS-CoV2 antibody testing was positive. Multiple inflammatory markers and cardiac biomarkers were elevated. Echocardiogram demonstrated mildly depressed left ventricular function and no coronary anomalies noted. The patient required mechanical ventilation, vasopressors, and eventually extracorporeal membrane oxygenation (ECMO) for profound circulatory shock and progressive respiratory failure. During his clinical course, recovery of cardiac function was demonstrated however, a middle cerebral artery infarct and left frontal subarachnoid hemorrhage was suffered which ultimately the patient succumbed to. To the best of our knowledge, this is the youngest previously healthy child who had multi-system hyperinflammatory syndrome requiring ECMO support and the first case of SARS-CoV-2 related pediatric stroke.Clinical Trial Registration: None.

ABSTRACT

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) initially most appreciated for its pulmonary symptoms, is now increasingly recognized for causing multi-organ disease and stroke in the setting of a hypercoagulable state. We report a case of 33-year-old African American woman with COVID-19 who developed acute malignant middle cerebral artery infarction due to thromboembolic occlusion of the left terminal internal carotid artery and middle cerebral artery stem. Mechanical thrombectomy was challenging and ultimately unsuccessful resulting in limited reperfusion of <67% of the affected vascular territory, and thrombectomized clot was over 50 mm in length, at least three times the average clot length. The final stroke size was estimated at 224 cubic centimeters. On admission her D-dimer level was 94,589 ng/mL (normal 0-500 ng/ml). Throughout the hospitalization D-dimer decreased but never reached normal values while fibrinogen trended upward. Hypercoagulability panel was remarkable for mildly elevated anticardiolipin IgM of 16.3 MPL/mL (normal: 0-11.0 MPL/mL). With respect to remaining stroke workup, there was no evidence of clinically significant stenosis or dissection in the proximal internal carotid artery or significant cardioembolic source including cardiomyopathy, atrial fibrillation, cardiac thrombus, cardiac tumor, valvular abnormality, aortic arch atheroma, or patent foramen ovale. She developed malignant cytotoxic cerebral edema and succumbed to complications. This case underscores the importance of recognizing hypercoagulability as a cause of severe stroke and poor outcome in young patients with COVID-19 and highlights the need for further studies to define correlation between markers of coagulopathy in patients with COVID-19 infection and outcome post stroke.

ABSTRACT

Coronavirus disease 2019 (COVID-19) is a pandemic disease currently affecting millions of people worldwide. Its neurological implications are poorly understood, and further study is urgently required. A hypercoagulable state has been reported in patients with severe COVID-19, but nothing is known about coagulopathy in patients with milder disease. We describe cases of patients in New York City presenting with stroke secondary to large vessel thrombosis without occlusion, incidentally found to have COVID-19 with only mild respiratory symptoms. This is in contrast to the venous thrombosis and microangiopathy that has been reported in patients with severe COVID-19. Our cases suggest that even in the absence of severe disease, patients with COVID-19 may be at increased risk of thrombus formation leading to stroke, perhaps resulting from viral involvement of the endothelium. Further systematic study is needed because this may have implications for primary and secondary stroke prevention in patients with COVID-19.
