Meniscus Sign in Patients with Anterior Circulation Large Vessel Occlusion Stroke does not Predict Outcome
ConclusionThe presence of MS in acute ischemic stroke patients with anterior circulation large vessel occlusion who undergo EVT does not appear to influence angiographic or clinical outcomes.

Unsupervised Deep Learning for Stroke Lesion Segmentation on Follow-up CT Based on Generative Adversarial Networks FUNCTIONAL
CONCLUSIONS: An unsupervised generative adversarial network can be used to obtain automated infarct lesion segmentations with a moderate Dice similarity coefficient and good volumetric correspondence.

Dual-Layer Detector Cone-Beam CT Angiography for Stroke Assessment: First-in-Human Results (the Next Generation X-ray Imaging System Trial) INTERVENTIONAL
CONCLUSIONS: In a single-center stroke setting, dual-layer detector cone-beam CTA virtual monoenergetic images are noninferior to CTA under certain conditions. Notably, the prototype is hampered by a long scan time and is not capable of contrast media bolus tracking. After excluding examinations with such scan issues, readers considered dual-layer detector cone-beam CTA noninferior to CTA, despite more artifacts.

Safety and efficacy of eptifibatide in acute ischemic stroke requiring extracranial carotid artery stenting
CONCLUSIONS: Eptifibatide may have a role in the management of acute stroke requiring carotid stenting. Caution may be required in those with established infarct on presentation imaging.PMID:37574792 | DOI:10.1177/15910199231193928

A Controlled Trial of Revascularization in Acute Stroke Neuroradiology
Conclusion: In this controlled trial, intraarterial revascularization with stents was an effective and safe-effective treatment option in patients with acute MCA occlusion with contraindication to IVT or after IVT failure. © RSNA, 2012

Predictors of Functional Outcome after Emergency Carotid Artery Stenting and Intra-Arterial Thrombolysis for Treatment of Acute Stroke Associated with Obstruction of the Proximal Internal Carotid Artery and Tandem Downstream Occlusion INTERVENTIONAL
CONCLUSIONS: Initial stroke severity, degree of successful revascularization, and the side of ischemia were found to independently predict the functional outcome at 3 months after treatment.

Effectiveness of micron‐sized superparamagnetic iron oxide particles as markers for detection of migration of bone marrow‐derived mesenchymal stromal cells in a stroke model
Conclusion:This study suggests that the use of MPIOs as labeling agents are insufficient to conclusively determine the localization of iron within cells in regions of neuronal ischemia and hemorrhage. J. Magn. Reson. Imaging 2013;37:1409–1418. © 2012 Wiley Periodicals, Inc.

Flat Detector Angio-CT following Intra-Arterial Therapy of Acute Ischemic Stroke: Identification of Hemorrhage and Distinction from Contrast Accumulation due to Blood-Brain Barrier Disruption INTERVENTIONAL
CONCLUSIONS: Flat panel CT after endovascular stroke treatment was able to exclude the rare event of an intracranial hemorrhage with a high negative predictive value. Future studies should evaluate the predictive value of BBB disruptions in flat panel detector CT for the development of relevant hematomas.

Recanalization and Mortality Rates of Thrombectomy With Stent-Retrievers in Octogenarian Patients with Acute Ischemic Stroke
Conclusions In our series, treatment with stent-retrievers in octogenarians with acute ischemic stroke achieved good rates of recanalization but with a high mortality rate. ICA involvement and revascularization times beyond 6 hours associated to a worse prognosis. These data might be of value in the design of prospective studies evaluating the clinical efficacy of the endovascular treatments in octogenarians.

Detection of Intraparenchymal Hemorrhage After Endovascular Therapy in Patients with Acute Ischemic Stroke Using Immediate Postprocedural Flat‐Panel Computed Tomography Scan
CONCLUSIONThe absence of hyperdense lesions on immediate postprocedural flat‐panel CT scan of ischemic stroke patients can exclude IPH with a high sensitivity and negative predictive value. The hyperdense parenchymal lesions visualized on flat‐panel versus multidetector CT studies may have comparable sensitivity and negative predictive value for the detection of IPH.

Stent-based thrombectomy versus intravenous tissue plasminogen activator in acute ischaemic stroke: A systematic review and meta-analysis.
CONCLUSION: Stentrievers can achieve a high rate of recanalisation and functional independence in acute ischaemic stroke and have a relatively good safety profile. Our meta-analysis demonstrates a clear benefit of an intra-arterial mechanical approach vs standard treatment. PMID: 26490828 [PubMed - as supplied by publisher]

Emergency Stenting of the Extracranial Internal Carotid Artery in Combination with Anterior Circulation Thrombectomy in Acute Ischemic Stroke: A Retrospective Multicenter Study EXTRACRANIAL VASCULAR
CONCLUSIONS: Emergency stent placement in the extracranial internal carotid artery in combination with anterior circulation thrombectomy is effective and safe. It is not associated with a significantly higher risk of symptomatic intracranial hemorrhage compared with published series for mechanical thrombectomy alone.
