AI software detection of large vessel occlusion stroke on CT angiography: a real-world prospective diagnostic test accuracy study
Conclusions These accuracy metrics support Viz LVO as a useful adjunct tool in stroke diagnostics. Fast and accurate diagnosis with high negative predictive value mitigates missing potentially salvageable patients.

Association between anesthesia modality and clinical outcomes following endovascular stroke treatment in the extended time window
Conclusion LA without sedation during EVT was associated with improved functional outcomes compared with GA, but not CS, within and beyond 6 hours from stroke onset. Prospective studies assessing anesthesia-related outcomes in the extended time window are warranted.

Predictors and clinical relevance of hemorrhagic transformation after endovascular therapy for anterior circulation large vessel occlusion strokes: a multicenter retrospective analysis of 1122 patients
Conclusions Greater understanding about the predictors and consequences of ICH post endovascular stroke therapy is essential to improve risk assessment, patient selection/clinical outcomes, and early prognostication. Our data suggest that patients with atrial fibrillation are particularly prone to severe ICH and question the ‘benign’ nature of HI suggested by earlier studies.

Endovascular therapy for acute ischemic stroke is indicated and evidence based: a position statement
In February 2013, three prospective randomized controlled trials were published simultaneously in the New England Journal of Medicine—the Interventional Management of Stroke (IMS III),1 Mechanical Retrieval and Recanalization of Stroke Clots Using Embolectomy (MR RESCUE),2 and SYNTHESIS-Expansion trials.3 Each of these studies demonstrated no benefit for endovascular intervention over medical management for patients with acute ischemic stroke (AIS). However, these trials suffered from significant design flaws which were largely related to a very slow rate of patient enrollment, and resulted in the subsequent obsolesc...

Thrombectomy for acute ischemic stroke: an evidence-based treatment
Just 2 years ago, at the International Stroke Conference in Honolulu, Hawaii, USA, the Interventional Management of Stroke (IMS III),1 Mechanical Retrieval and Recanalization of Stroke Clots Using Embolectomy (MR RESCUE),2 and SYNTHESIS-Expansion3 trials were presented and concurrently published in The New England Journal of Medicine. The overarching message to the medical community and lay press was that these studies provided unambiguous evidence that mechanical thrombectomy was ineffective in treating acute stroke secondary to emergent large vessel occlusion (ELVO). The investigators were careful to emphasize the a...

P-006 evaluation of baseline ct aspects and admission neutrophil-lymphocyte ratio in perfusion-guided selected ica/mca stroke patients for endovascular reperfusion therapy
ConclusionsIn our cohort, baseline CT ASPECTS inversely correlated with admission NLR in anterior circulation AIS patients who had favorable perfusion imaging profile for IA reperfusion therapy. Additionally, in this subgroup of patients, NLR of 5 or less discriminated favorable from unfavorable ASPECTS.DisclosuresA. Honarmand: None. A. Shaibani: None. F. Syed: None. A. Elmokadem: None. M.

E-063 validation of the interventional stroke assessment scale for eligibility in endovascular therapy (isas-et)
ConclusionThe use ISAS-ET scale appears to be appropriate in this single center study at predicting outcome using parameters prior to intervention. This data may help determine the urgency of transfer for intervention in hospitals without endovascular capabilities while helping determine which patients will benefit significantly from intervention.DisclosuresH.

Clinical significance of the circle of Willis in intracranial atherosclerotic stenosis
Conclusions If patients have poor integrity of the circle of Willis, the risk of recurrent stroke may be increased. Such patients appear to be good candidates for endovascular treatment.

O-028 Opercular Index Score (OIS): A Novel Predictor of Collateral Robustness and Neurologic Outcomes in the Endovascular Management of Acute Ischemic Stroke

P-004 Publishing Title: Incidence of Large Vessel Occlusions Amongst All Hospital Discharges for Acute Ischemic Stroke - Estimating a Thrombectomy Eligible Population
ConclusionAlmost 12% of the patients in our large rural sample of AIS hospital discharges presented with an ELVO. This translated to 133,388 patients when extrapolated to the NIS-database for 2013. An estimated 48,579 patients within 6 hours and 27,172 patients after 6 hours could be thrombectomy eligible based on ASPECTS ≥6. An additional 22,643 patients were estimated to have a basilar occlusion. These are estimates based on a stroke center within a healthcare system serving a large rural population and probably represent the upper limit since the area under study has one of the highest ischemic stroke rates in the co...

P-015 Influence of Core Infarct Volume and Patient Age on Clinical Outcome in Endovascular Treatment of Large Vessel Occlusion for Acute Stroke
ConclusionThis study found TICI 2 B/3 reperfusion, core volume, age, and baseline NIHSS were independent predictors for good outcome. ROC analysis demonstrated a core infarct volume of <45 ml had a PPV of at least 10% of yielding a good outcome. For patients >80 years the ROC analysis demonstrated that a core infarct volume of <16 ml had a PPV of 10% or better of yielding a good outcome, suggesting that older patients tolerate a smaller core. However, the current study was underpowered to identify the significance of this threshold.DisclosuresN. Telischak: None. A. Faisal: None. J. Wong: None. A. Moraff: None. H. ...

E-020 Between a Rock and a Hard Place: The Use of Self-expanding Stents for the Endovascular Treatment of Acute Ischemic Stroke due to Recalcitrant Emergency Large Vessel Occlusion in the Era of Stent-retrievers: Single-center Experience and Early Results
ConclusionInitial results suggest that acute intracranial stenting may be beneficial in a subset of patients who present with an ELVO and who have failed recanalization by means of mechanical thrombectomy with stent-retrievers and/or thromboaspiration with large bore intracranial catheters.DisclosuresJ.

E-027 Mechanical Thrombectomy for Acute Ischemic Stroke in Post-surgical Patients
ConclusionIn our experience, emergent angiography among post-surgical stroke patients showed proximal vessel occlusion in more than half of patients, making them potential candidates for mechanical thrombectomy. Those who achieved TICI 2 b/3 recanalization performed clinically better than those who did not. This may indicate the potential benefit of mechanical thrombectomy among post-surgical stroke patients. The overall lower recanalization rates in this cohort may reflect atypical clot characteristics encountered in post-surgical patients and would be an interesting avenue for further investigation.DisclosuresM.
