E-238 A jellyfish in the net - a case of recurrent stroke caused by a mobile floating carotid intimal plaque
ConclusionMobile floating carotid intimal plaque is a rare cause of embolic events. While the carotid stenosis is not severe, a meticulous examination of carotid doppler sonography needed to find any embolic source.Disclosures S. Lee: None. Y. Won: None.

E-250 Flow diversion of superior cerebellar artery aneurysms
ConclusionWhile our data is preliminary and reflects the uncommon nature of these aneurysms, flow diversion of SCA aneurysms with PED appears to be carry a high risk of clinical complications and a low likelihood of complete aneurysm occlusion. Caution when pursuing flow diversion in these aneurysms is warranted. Further study in larger cohorts is necessary to better define clinical scenarios in which flow diversion or other interventions for SCA aneurysms should be considered.Disclosures D. Lauzier: None. S.

Cerebral angiographic features of central retinal artery occlusion patients treated with intra-arterial thrombolysis
Conclusions There was a significant correlation in the severity of steno-occlusive lesions between the OphA and the ipsilateral CA in patients with CRAO. The patients with less severe angiographic features in the CA showed a more improved retinal reperfusion after IAT. The angiographic findings in the CA may serve as a predictive marker for the vessel integrity of the OphA and recanalization outcome after IAT.

Successful mechanical thrombectomy in acute ischemic stroke: revascularization grade and functional independence
Most studies define the technical success of endovascular thrombectomy (EVT) as a Thrombolysis in Cerebral Infarction (TICI) revascularization grade of 2b or higher. However, growing evidence suggests that TICI 3 is the best angiographic predictor of improved functional outcomes. To assess the association between successful TICI revascularization grades and functional independence at 90 days, we performed a systematic review and network meta-analysis of thrombectomy studies that reported TICI scores and functional outcomes, measured by the modified Rankin Scale, using the semi-automated AutoLit software platform. Forty stu...

Diagnostic performance of an algorithm for automated large vessel occlusion detection on CT angiography
Conclusion The algorithm provided a high detection rate for proximal LVO, but performance varied significantly by occlusion location. Detection of M2 occlusion needs further improvement.

Development of a machine learning-based real-time location system to streamline acute endovascular intervention in acute stroke: a proof-of-concept study
Conclusions ML-based RTLS technology using WiFi fingerprinting has the potential to streamline delivery of acute stroke endovascular intervention by efficiently tracking patient and staff movement during stroke calls.

'Drip-and-ship' intravenous thrombolysis and outcomes for large vessel occlusion thrombectomy candidates in a hub-and-spoke telestroke model
Conclusions Intravenous alteplase at spoke hospitals may improve discharge and 90 day mRS and should not be withheld from EVT eligible patients who first present at alteplase capable spoke hospitals that do not perform EVT. Additional studies are warranted to confirm and further explore these benefits.

Internal cerebral vein asymmetry is an independent predictor of poor functional outcome in endovascular thrombectomy
Conclusion ICV asymmetry is a novel radiological sign which is independently associated with poor functional outcomes in EVT, even after correction for collateral circulation. Further studies are needed to validate this finding.

Multi-centric European post-market follow-up study of the Neuroform Atlas Stent System: primary results
Conclusions In this multicentric, prospective study, stent-assisted coiling of medium size unruptured aneurysms with the Neuroform Atlas stent resulted in a favorable rate of satisfactory occlusion. In our findings, the use of the Y-stenting technique was associated with increased rates of procedural complications. Clinical trial registration https://clinicaltrials.gov/ct2/show/NCT02783339.

Carotid webs produce greater hemodynamic disturbances than atherosclerotic disease: a DSA time-density curve study
Conclusion CaW results in larger local hemodynamic disruption, characterized by flow stasis, than mild/moderate carotid atherosclerotic lesions, suggesting that CaWs may produce larger regions of thrombogenic flow stasis.

Device size selection can enhance Y-stentrieving efficacy and safety as a rescue strategy in stroke thrombectomy
Conclusion Y-stentrieving is an effective and safe bail-out strategy for refractory bifurcation clots. Longer stents may promote better angiographic outcomes, whereas avoidance of disproportionately large retrievers may mitigate intracranial hemorrhage. Future studies should account for these factors when evaluating alternative stentriever techniques.
