Mechanical thrombectomy in COVID-19-associated ischaemic stroke: patient characteristics and outcomes in a single-centre study
CONCLUSION: In AIS patients treated with MT, concomitant SARS-CoV2 infection did not affect the outcome. Our observations need to be confirmed in larger, and preferably multicentre, studies.PMID:35315928 | DOI:10.5603/PJNNS.a2022.0026

Beneficial Effect of Sodium Nitrite on EEG Ischaemic Markers in Patients with Subarachnoid Haemorrhage
AbstractSubarachnoid haemorrhage (SAH) is associated with long-term disability, serious reduction in quality of life and significant mortality. Early brain injury (EBI) refers to the pathological changes in cerebral metabolism and blood flow that happen in the first few days after ictus and may lead on to delayed cerebral ischaemia (DCI). A disruption of the nitric oxide (NO) pathway is hypothesised as a key mechanism underlying EBI. A decrease in the alpha-delta power ratio (ADR) of the electroencephalogram has been related to cerebral ischaemia. In an experimental medicine study, we tested the hypothesis that intravenous...

Study on the Correlation between different Levels of Patients with Vertebrobasilar Dolichoectasia and Posterior Circulation Blood Perfusion
This study investigates the differences and changing trend of posterior circulation blood perfusion between different levels of vertebrobasilar dolichoectasia(VBD) patients. The relationship between the deviation of the basilar artery(BA) in different directions and the location of pontine infarction are also investigated.

Predictors of Early Neurological Improvement in Patients with Anterior Large Vessel Occlusion and Successful Reperfusion Following Endovascular Thrombectomy —Does CT Perfusion Imaging Matter?
ConclusionCTP ASPECTS might better predict ENI than non-contrast CT at baseline in patients with successful reperfusion following EVT.

Added Value of Arterial Spin Labeling in Detecting Posterior Reversible Encephalopathy Syndrome as a Stroke Mimic on Baseline Neuroimaging: A Single Center Experience
Differentiating stroke from stroke mimics is a diagnostic challenge in every day practice. Posterior Reversible Encephalopathy Syndrome (PRES) is an important stroke mimic with nonspecific symptomatology, making prompt and accurate diagnosis challenging. Baseline neuroimaging plays a pivotal role in detection and differentiation of stroke from many common mimics and is thus critical in guiding appropriate management. In particular, MR perfusion (MRP) imaging modalities provide added value through detection and quantification of multiple physiological parameters. Arterial Spin Labeling (ASL) is a non-contrast, noninvasive M...

Outcome of Superficial Temporal Artery-to-Middle Cerebral Artery Bypass in Appropriately Selected Patients with Acute Ischemic Stroke
Conclusions: Urgent STA-MCA bypass for progressive stroke may result in a good prognosis if the right patients are selected and may play an important role in cases treated 24 h after onset in whom endovascular treatment is ineffective.

Ultrasound Perfusion Imaging for the Detection of Cerebral Hypoperfusion After Aneurysmal Subarachnoid Hemorrhage
ConclusionsUPI is feasible to enable detection of cerebral tissue hypoperfusion after aSAH, and the left –right difference of TTP values is the most indicative result of this finding.

Stroke Core Volume Weighs More Than Recanalization Time for Predicting Outcome in Large Vessel Occlusion Recanalized Within 6 h of Symptoms Onset
ConclusionCore stroke volume better explains outcome variability in comparison to the time to recanalization in anterior large vessel occlusion stroke with successful thrombectomy done within 6 h of symptoms onset. Still, a large part of outcome variability prediction fails to be explained by the usual predictors.

The Predictive Accuracy of the Delayed Spot Sign for Haematoma Expansion in Spontaneous Supratentorial Intracerebral Haemorrhage: A Systematic Review and Meta-Analysis
Previous studies have shown that spot signs on imaging modalities such as CT perfusion, delayed phase CTA or post contrast CT imaging reportedly have greater ability to predict haematoma expansion (HE) than the traditional CT angiography spot sign. We performed a systematic review and meta-analysis of the diagnostic accuracy of the spot sign on delayed imaging modalities in predicting haematoma expansion.Pubmed, Excerpta Medica Database, and the Cochrane library were searched on the 11 November 2019.

Independent Significance of Visual Assessment of Perfusion CT Maps in Anterior Circulation Stroke Patients Treated with Mechanical Thrombectomy
ConclusionWe demonstrated that both visually graded CTP and collateral circulation grade strongly correlated with the clinical outcome of MT in the anterior circulation of AIS patients. Importantly, CTP correlated with the clinical outcome independent of the collateral circulation.

Hypoperfusion Intensity Ratio Predicts Infarct Growth After Successful Thrombectomy for Distal Medium Vessel Occlusion
ConclusionGood collaterals on initial CTP assessed by an HIR< 0.3 are associated with less infarct growth after successful recanalization of AIS caused by a DMVO.

Data Do Not Support Selection of Patients for Stroke Treatment Within the 16- to 24-Hour Interval
To the Editor The Diffusion-Weighted Imaging or Computerized Tomography Perfusion Assessment With Clinical Mismatch in the Triage of Wake-Up and Late Presenting Strokes Undergoing Neurointervention With Trevo (DAWN) trial demonstrated benefit of endovascular treatment (EVT) in select patients 6 to 24 hours after last known well (LKW) with clinical imaging mismatch. The Endovascular Therapy Following Imaging Evaluation for Ischemic Stroke 3 (DEFUSE 3) trial demonstrated benefit of EVT in select patients 6 to 16 hours after LKW with target perfusion-imaging mismatch. In the article by Albers et al, the authors present indepe...

Data Do Not Support Selection of Patients for Stroke Treatment Within the 16- to 24-Hour Interval —Reply
In Reply We thank Powers for his comments regarding our article. He raises the question if the positive result for patients with target perfusion-imaging mismatch in the 12.8- to 24-hour tercile in the Analysis of Pooled Data From Randomized Studies of Thrombectomy More Than 6 Hours After Last Well Known (AURORA) study could solely be due to a benefit from 12.8 to 16 hours since last known well subgroup, with neutral or negative effects in the 16- to 24-hour time period. This was not the case. Data for patients in the 16- to 24-hour group with the target mismatch profile demonstrated an odds ratio of 3.82 (95% CI, 1.07-13....
