Influence of coronavirus disease 2019 (COVID-19) on working flow, safety and efficacy outcome of mechanical thrombectomy for acute ischemic stroke with large vessel occlusion
CONCLUSIONS: Prolongation of the working time flow during the COVID-19 epidemic did not influence the safety and efficacy of EVT in AIS patients with LVO. However, special policy and particular measures in this circumstances is still need to evolve to improve the treatment quality.PMID:34000867 | DOI:10.1177/15910199211018093

Special report of the RSNA COVID-19 task force: systematic review of outcomes associated with COVID-19 neuroimaging findings in hospitalized patients
CONCLUSION: Among hospitalized COVID-19 patients with abnormal neuroimaging findings, those with ICH had the highest all-cause mortality; however, high mortality rates were also seen among COVID-19 patients with ischemic stroke in the acute/subacute period and leukoencephalopathy in the chronic period.ADVANCES IN KNOWLEDGE: Specific abnormal neuroimaging findings may portend differential mortality outcomes, providing a potential prognostic marker for hospitalized COVID-19 patients.PMID:33914618 | DOI:10.1259/bjr.20210149

Abstract No. 550 The impact of stay-at-home orders on code stroke activations and mechanical thrombectomy
Stay-at-home orders and additional fears of the COVID-19 pandemic led to a decrease in the presentation of patients with stroke symptoms in emergency departments across some regions in the U.S. but without a similar decline in mechanical thrombectomy (MT) (1). However, a significant decrease of MT cases was observed in other countries such as France (2). It is unknown if the same phenomenon was observed across the entire U.S. The purpose of this study was to review the volumes of code stroke activation, emergent large vessel occlusion (ELVO) activation, and MT cases in a Stroke Belt region during statewide stay-at-home mea...

Analysis of Stroke Detection during the COVID-19 Pandemic Using Natural Language Processing of Radiology Reports ADULT BRAIN
CONCLUSIONS: Acute or subacute ischemic stroke cases detected by neuroimaging decreased during the COVID-19 pandemic, though a higher proportion of studies ordered for stroke were positive for acute or subacute ischemic strokes. Natural language processing approaches can help automatically track acute or subacute ischemic stroke numbers for epidemiologic studies, though local classifier training is important due to radiologist reporting style differences.

Endovascular Thrombectomy of COVID-19-Related Large Vessel Occlusion: A Systematic Review and Summary of the Literature
ConclusionDespite angiographically successful EVT of LVOs in the majority of patients, this literature analysis demonstrates overall poor outcomes and high mortality in COVID-19 patients post EVT. An unusual incidence of early intracerebral proximal arterial re-occlusion was notable.
