ABSTRACT

BACKGROUND AND PURPOSE: Acute ischemic stroke and large vessel occlusion can be concurrent with the coronavirus disease 2019 (COVID-19) infection. Outcomes after mechanical thrombectomy (MT) for large vessel occlusion in patients with COVID-19 are substantially unknown. Our aim was to study early outcomes after MT in patients with COVID-19. METHODS: Multicenter, European, cohort study involving 34 stroke centers in France, Italy, Spain, and Belgium. Data were collected between March 1, 2020 and May 5, 2020. Consecutive laboratory-confirmed COVID-19 cases with large vessel occlusion, who were treated with MT, were included. Primary investigated outcome: 30-day mortality. SECONDARY OUTCOMES: early neurological improvement (National Institutes of Health Stroke Scale improvement ≥8 points or 24 hours National Institutes of Health Stroke Scale 0-1), successful reperfusion (modified Thrombolysis in Cerebral Infarction grade ≥2b), and symptomatic intracranial hemorrhage. RESULTS: We evaluated 93 patients with COVID-19 with large vessel occlusion who underwent MT (median age, 71 years [interquartile range, 59-79]; 63 men [67.7%]). Median pretreatment National Institutes of Health Stroke Scale and Alberta Stroke Program Early CT Score were 17 (interquartile range, 11-21) and 8 (interquartile range, 7-9), respectively. Anterior circulation acute ischemic stroke represented 93.5% of cases. The rate modified Thrombolysis in Cerebral Infarction 2b to 3 was 79.6% (74 patients [95% CI, 71.3-87.8]). Thirty-day mortality was 29% (27 patients [95% CI, 20-39.4]). Early neurological improvement was 19.5% (17 patients [95% CI, 11.8-29.5]), and symptomatic intracranial hemorrhage was 5.4% (5 patients [95% CI, 1.7-12.1]). Patients who died at 30 days exhibited significantly lower lymphocyte count, higher levels of aspartate, and LDH (lactate dehydrogenase). After adjustment for age, initial National Institutes of Health Stroke Scale, Alberta Stroke Program Early CT Score, and successful reperfusion, these biological markers remained associated with increased odds of 30-day mortality (adjusted odds ratio of 2.70 [95% CI, 1.21-5.98] per SD-log decrease in lymphocyte count, 2.66 [95% CI, 1.22-5.77] per SD-log increase in aspartate, and 4.30 [95% CI, 1.43-12.91] per SD-log increase in LDH). CONCLUSIONS: The 29% rate of 30-day mortality after MT among patients with COVID-19 is not negligible. Abnormalities of lymphocyte count, LDH and aspartate may depict a patient's profiles with poorer outcomes after MT. Registration: URL: https://www.clinicaltrials.gov.

ABSTRACT

We describe a case of a 47-year-old Italian, immunocompromised, and obese woman infected by COVID-19 presenting with fever (39.6 °C) and respiratory symptoms. Neurological examination was normal. Chest CT findings consist of bilateral interstitial pneumonia (visual score extension: 30%). The patient was treated with antiviral drugs and anti-inflammatory drugs with supportive care. Seven days after admission to Covid-19 Unit, the patient rapidly developed worsening respiratory failure and acute respiratory distress syndrome (ARDS). She suddenly developed partial left hemispheric syndrome. A new HRCT scan of her thorax revealed diffuse ground-glass opacities in both lungs (visual score extension: 90%). Brain CT performed 2 h after sudden-onset left-sided weakness showed subtle low attenuation within the right insular ribbon and frontal lobe (ASPECT Score 8). Multiphasic CT angiography (MCTA) demonstrated occlusion of both the dominant inferior division of the right middle cerebral artery and the A2 segment of the right anterior cerebral artery. After 24 h, her pupils became dilated and unreactive, and brain CT demonstrated large bilateral infarctions of both the cerebellar and cerebral hemispheres. She had a rapid progression of interstitial pneumonia from COVID-19, developed multiple strokes, and died 1 day later. SARS-CoV-2 infection seems to predispose pluripathological subjects to cerebrovascular complications.
