The Great Contrast Shortage of 2022 —Lessons learnt in Australia
ConclusionOur findings demonstrate that the IBCM shortage crisis had a very significant impact on the delivery of healthcare. While V/Q scans could (partially) substitute for CTPA studies in suspected pulmonary emboli, there appeared to be no valid alternative for CTNA studies in stroke calls. The unexpected and critical shortage of IBCM forced healthcare professionals to conserve resources, prioritise indications, triage patients based on risk, explore alternate imaging strategies and prepare for similar events recurring in the future.

Neurological manifestations of COVID-19: a retrospective observational study based on 1060 patients with a narrative review
CONCLUSION: Our data are coherent with the published literature. Knowledge of these patterns will make clinicians consider COVID-19 infection when unexplained neurological findings are encountered.PMID:36451533 | DOI:10.1177/02841851221138557

Dual antiplatelet use in the management of COVID-19 associated acute ischemic stroke reocclusion
CONCLUSION: COVID-19 AIS may be associated with a hypercoagulable state which risks malignant reocclusion complicating MT. We found antithrombotic treatment periprocedural cangrelor with or without argatroban transitioned to oral aspirin with ticagrelor to be a viable method for management of these patients.PMID:35549746 | DOI:10.1177/15910199221097484

Endovascular mechanical thrombectomy in a child with COVID-19: Clot analysis reveals a novel pathway in the neuroinflammatory cascade resulting in large-vessel occlusion
Interv Neuroradiol. 2022 Apr 21:15910199221094758. doi: 10.1177/15910199221094758. Online ahead of print.ABSTRACTLarge-vessel occlusion is rare in children, but its results can be devastating and may lead to recurrent strokes, persistent neurological deficits, and decreased quality of life. Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has yielded extrapulmonary effects and multiorgan diseases, many of which are neurological manifestations. There is a paucity of literature in pediatric patients about large-vessel occlusion in the setting of COVID-19 infection. We discuss a nine-year-old child who presented w...

Impact of SARS-CoV-2 vaccines on the nervous system
We read with interest the article by Goulart Correa et al. about three patients experiencing neurological side effects after the first dose of the AstraZeneca vaccine.1 Patient-1 was a 64yo male who experienced an ischemic stroke two days after vaccination.1 Patient-2 was a 42yo male who experienced left-sided facial palsy seven days after the vaccination.1 Patient-3 is a 65yo male who experienced transverse myelitis 8d after being vaccinated.1 The study is appealing but raises concerns.

Brain and Lung Imaging Correlation in Patients with COVID-19: Could the Severity of Lung Disease Reflect the Prevalence of Acute Abnormalities on Neuroimaging? A Global Multicenter Observational Study ADULT BRAIN
CONCLUSIONS: The CT lung disease severity score may be predictive of acute abnormalities on neuroimaging in patients with COVID-19 with neurologic manifestations. This can be used as a predictive tool in patient management to improve clinical outcome.

Impact of SARS-CoV-2 Pandemic on "Stroke Code" Imaging Utilization and Yield ADULT BRAIN
CONCLUSIONS: During our pandemic period, there was a significantly decreased number of stroke codes but simultaneous increases in positivity rates, symptom severity, and inpatient codes. We postulate that this finding reflects the documented reluctance of patients to seek medical care during the pandemic, with the shift toward a greater proportion of inpatient stroke codes potentially reflecting the neurologic complications of the virus itself.

Stroke management during the COVID-19 outbreak: challenges and results of a hub-center in Lombardy, Italy
ConclusionEndovascular treatment of stroke presented several challenges during the COVID-19 outbreak. Within the hospital, special pathways can be used to maintain both procedural safety and procedural times.

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...
