Role of CT Perfusion in Identifying the Core and the Potentially Salvageable Penumbra in Patients with Acute Non Haemorrhagic Stroke - Experience at Tertiary Care Center
CONCLUSION: CT Perfusions study being easily available, faster and cost effctive modality to identfy patients of acute ischemic strokes having salvagable penumbra for which further can be subjected to revasculrization therapy. It is strongly recommended that CT Perfusion should be made an integral part of acute non-haemorrhagic stroke management protocol, wherever the facility is available.PMID:34781606

Outcomes of Mechanical Thrombectomy in the Early * (=6-hour) Time Window Based Solely on Noncontrast CT and CT Angiography: A Propensity Score-Matched Cohort Study INTERVENTIONAL
CONCLUSIONS: Patients selected for mechanical thrombectomy in the extended time window solely on the basis of noncontrast CT and CTA still achieved decent rates of favorable 90-day functional outcomes, not statistically different from patients in the early time window.

Ocular and systemic determinants of perifoveal and macular vessel parameters in healthy African Americans
CONCLUSIONS: When interpreting OCTA images in a clinical setting, it is important to consider the effects ocular and systemic characteristics may have on the macular microcirculation.PMID:34740885 | DOI:10.1136/bjophthalmol-2021-319675

The Effect of Data Length on the Assessment of Dynamic Cerebral Autoregulation with Transfer Function Analysis in Neurological ICU Patients
ConclusionsConsidering the acceptable rates for the data and the variation in the TFA variables (phase shift and gain), we recommend recording data for a minimum length of 7  min for TFA in patients in the neuro-ICU.

Cerebral Perfusion Imaging for Intravenous Thrombolysis Treatment
Intravenous thrombolysis is the cornerstone of acute ischemic stroke treatment. However, the benefits of recanalization and reperfusion must be balanced against the risk of intracranial hemorrhage. Time from symptom onset was previously the most important selection tool for identifying patients who would benefit from treatment without prohibitive risk for secondary hemorrhage. Enhanced techniques in noncontrast computed tomography followed by computed tomography and magnetic resonance perfusion imaging led to the expansion of treatment eligibility for intravenous thrombolysis. Perfusion imaging allows for more precise eval...

LB-006 Collateral imaging of stroke patients in the late window prior to endovascular thrombectomy results from a pooled individual patient-level multicenter analysis
ConclusionIn this pooled individual patient-level analysis from multi-national studies and registries, late window patients who were selected for EVT using collateral imaging achieved comparable functional outcomes to patients who had perfusion imaging.DisclosuresM.

P-003 Association between baseline serology and symptomatic intracranial hemorrhage after endovascular thrombectomy for acute ischemic stroke
ConclusionOur findings, particularly the association of diabetes mellitus and high neutrophil count with post-EVT hemorrhage, support experimental data on the role of thromboinflammation in hemorrhagic transformation of large vessel occlusions.Disclosures J.

E-020 A novel technique to treat tandem occlusion by utilizing stentriever as the distal protection device with aspiration catheter
ConclusionThe novel technique to revascularize tandem occlusion utilizing a stent-retriever as a distal protection device along with an aspiration catheter and a balloon-guided catheter is feasible. Immediate flow restoration at the distal occlusion site with simultaneous revascularization of the proximal ICA steno-occlusive lesion potentially improves the puncture to reperfusion timeDisclosures S.

Cerebral Autoregulation in Subarachnoid Hemorrhage
Subarachnoid hemorrhage (SAH) is a devastating stroke subtype with a high rate of mortality and morbidity. The poor clinical outcome can be attributed to the biphasic course of the disease: even if the patient survives the initial bleeding emergency, delayed cerebral ischemia (DCI) frequently follows within 2 weeks time and levies additional serious brain injury. Current therapeutic interventions do not specifically target the microvascular dysfunction underlying the ischemic event and as a consequence, provide only modest improvement in clinical outcome. SAH perturbs an extensive number of microvascular processes, includi...

Reduction in Acute Stroke Admissions during the COVID-19 Pandemic: Data from a National Stroke Registry
Conclusion: The marked decrease in admissions for acute stroke and TIA, occurring at a time of a relatively low burden of COVID-19, is of great concern. Public awareness campaigns are needed as patients reluctant to seek urgent stroke care are deprived of lifesaving procedures and secondary prevention treatments.Neuroepidemiology
