Stroke Thrombectomy in Patients with COVID-19: Initial Experience in 13 Cases INTERVENTIONAL
SUMMARY: We performed a retrospective review in both comprehensive stroke units of a region affected early by the coronavirus disease 2019 (COVID-19) pandemic, between March 1 and April 26, 2020, including patients with COVID-19 who underwent mechanical thrombectomy for ischemic stroke. We identified 13 cases, representing 38.2% of 34 thrombectomies performed during this period. We observed increased mortality and a high incidence of thrombotic complications during hospitalization. Given the high rate of infected patients, systematic use of full personal protection measures seems justified.

Pressing Issues in COVID-19: Probable Cause to Seize SARS-CoV-2 for Its Preferential Involvement of Posterior Circulation Manifesting as Severe Posterior Reversible Encephalopathy Syndrome and Posterior Strokes ADULT BRAIN
SUMMARY: Since December 2019, a novel Severe Acute Respiratory Syndrome coronavirus 2 from China has rapidly spread worldwide. Although respiratory involvement is the mainstay of coronavirus disease 2019 (COVID-19), systemic involvement has recently drawn more attention. In particular, a number of recent articles have shed light on the nervous system as one of the possible targets. At our institution, we observed 15 patients with acute brain vascular manifestations; most interesting, we had a higher prevalence of the posterior circulation acute impairment. In our series, 7 patients had acute posterior cerebral injury: 1, h...

Regional Mechanical Thrombectomy Imaging Protocol in Patients Presenting with Acute Ischemic Stroke during the COVID-19 Pandemic INTERVENTIONAL
CONCLUSIONS: Chest CT provides a pragmatic, rapid additional tool for COVID-19 risk stratification among patients referred for mechanical thrombectomy. Its inclusion in a standardized regional stroke imaging protocol has enabled efficient use of hospital resources with minimal compromise or delay to the overall patient treatment schedule.

Multiple embolic stroke on magnetic resonance imaging of the brain in a COVID-19 case with persistent encephalopathy
The pulmonary manifestations of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection or coronavirus disease 2019 (COVID-19) are well known. The literature on neurological manifestations and complications in patients with COVID-19 has been increasing but is still sparse. At present, there are only a few reported case reports and clinical studies on neurological manifestations of COVID-19, of which ischemic stroke is one of the most common ones. Coagulopathy and vascular endothelial dysfunction have been proposed as the complications of COVID-19 which can ultimately lead to ischemic stroke.

Intraluminal Carotid Artery Thrombus in COVID-19: Another Danger of Cytokine Storm? EXTRACRANIAL VASCULAR
We report a series of 6 patients with COVID-19 with acute ischemic stroke due to intraluminal carotid artery thrombus presenting during an 8-day period. Six patients were included (5 men) with a mean age of 65.8 years (range, 55–78 years). COVID-19 was diagnosed by detection of Severe Acute Respiratory Syndrome coronavirus 2 in 5 patients and was presumed due to typical clinical and imaging findings in 1 patient. All patients had vascular risk factors including diabetes (83%), hyperlipidemia (100%), and smoking (17%). Four patients presented with large infarcts with initial NIHSS scores of 24–30. During their h...

Predictors of mortality for patients with COVID-19 and large vessel occlusion.
CONCLUSION: Patients with COVID-19 and ELVO had a significantly higher risk for mortality compared to COVID-19 negative patients with ELVO. A small percentage of COVID-19 ELVO patients had good outcomes. Age greater than 60 and pulmonary symptoms at presentation have higher risk for mortality. Other risk factors for mortality were a history of cigarette smoking, elevated, failure to recanalize, elevated d-dimer and ferritin levels. PMID: 32862753 [PubMed - as supplied by publisher]

Critical illness-associated cerebral microbleeds in severe COVID-19 infection
Neurologic complications of COVID-19 infection have been recently described and include dizziness, headache, loss of taste and smell, stroke, and encephalopathy. Brain MRI in these patients have revealed various findings including ischemia, hemorrhage, inflammation, and demyelination. In this article, we report a case of critical illness-associated cerebral microbleeds identified on MRI in a patient with severe COVID-19 infection and discuss the potential etiologies of these neuroimaging findings.

Where have our patients gone? The impact of COVID ‐19 on stroke imaging and intervention at an Australian stroke centre
ConclusionsThe significant decrease in volume of ‘code stroke’ activations and acute stroke imaging following lockdown was accompanied by a concomitant decrease in patients with LVOs and ECRs. The decrease in imaging was therefore not driven purely by patients with mild strokes and stroke mimics, but also included those with severe strokes. Si nce Australia had a low prevalence of COVID‐19, this observed decrease cannot be attributed to hospital congestion and is instead likely driven by patient fear.
