Dual-energy computed tomography in acute ischemic stroke: state-of-the-art
AbstractDual-energy computed tomography (DECT) allows distinguishing between tissues with similar X-ray attenuation but different atomic numbers. Recent studies demonstrated that this technique has several areas of application in patients with ischemic stroke and a potential impact on patient management. After endovascular stroke therapy (EST), hyperdense areas can represent either hemorrhage or contrast staining due to blood-brain barrier disruption, which can be differentiated reliably by DECT. Further applications are improved visualization of early infarctions, compared to single-energy computed tomography, and predict...

Impact of bridging thrombolysis on clinical outcome in stroke patients undergoing endovascular thrombectomy: a retrospective analysis of a regional stroke registry
ConclusionsThe results of the present study suggest that bridging IVT does not seem to improve short-term clinical outcome of patients undergoing EVT. Nonetheless, there might be a subgroup of patients that benefits from IVT. This needs to be addressed in randomized controlled trials.

Comparison of various reconstructions derived from dual-energy CT immediately after endovascular treatment of acute ischemic stroke in predicting hemorrhage
ConclusionsImage markers on non-contrast CT (parenchymal hyperdensities and metallic hyperdensity sign) performed immediately post-EVT of ischemic stroke might be not inferior to dual-energy CT (parenchymal hyperdensities) to predict follow-up hemorrhage.Key Points• Image markers (parenchymal hyperdensities and metallic hyperdensity sign) on NCCT performed immediately post-EVT of ischemic stroke can predict follow-up hemorrhage.• Metallic hyperdensity sign on NCCT can accurately predict parenchymal hemorrhage.• Parenchymal hyperdensities on NCCT can accurately predict hemorrhagic transformation.

Predictors of unfavorable outcomes despite substantial reperfusion: Insights from Analysis of Revascularization in Ischemic Stroke With EmboTrap II Study
CONCLUSION: More severe initial neurologic deficit and higher number of passes in patients with substantial reperfusion were independent predictors of dependency or death. These findings highlight a reduction in the number of passes required to achieve reperfusion as a therapeutic target to improve the outcome after thrombectomy.PMID:34719305 | DOI:10.1177/15910199211051553

Predictors of favorable outcome after endovascular thrombectomy for acute ischemic stroke due to large vessel occlusion in young patients
CONCLUSION: In conclusion, the results of this study demonstrate that MT for AIS in young patients is feasible and provides an excellent rate of arterial recanalization and high rate of favorable outcomes. Statistical analysis showed that shorter time from onset to arrival and reperfusion, successful recanalization and absence of hemorrhagic transformation are the predictors of favorable clinical outcome and overall survival rate.PMID:34766505 | DOI:10.1177/02841851211056476

Conservative versus aggressive antiplatelet strategy for emergent carotid stenting during stroke thrombectomy
CONCLUSIONS: In this retrospective study, aggressive periprocedural antiplatelet strategy led to improved stent patency and clinical outcomes, without increased HT. Further prospective randomized research is warranted to identify the optimal combination of antiplatelet agents for emergent carotid stenting in the setting of acute stroke.PMID:35253529 | DOI:10.1177/15910199221083112

Safety and Efficacy of Cangrelor in Acute Stroke Treated with Mechanical Thrombectomy: Endovascular Treatment of Ischemic Stroke Registry and Meta-analysis INTERVENTIONAL
CONCLUSIONS: Cangrelor offers promising safety and efficacy profiles, especially considering the complex endovascular reperfusion procedures in which it is usually applied. Further large prospective data are required to confirm these findings.
