Rethinking the role of CT perfusion in the management of emergent large vessel ischemic stroke
The treatment of emergent large vessel occlusion (ELVO) was revolutionized by endovascular thrombectomy (EVT). The identification of eligible patients for EVT has sparked significant interest in determining the neuroimaging modality that offers optimal results. The American Stroke Association recommend the use of both non-contrast CT and CT angiogram for patients coming in the early window (0–6 hours).1 In the late window (6–24 hours) the randomized trials, DAWN and DEFUSE 3, showed clinical benefit utilized some form of quantitative estimation of the core infarct.2 3 Consequently the society recommends automat...

Alberta Stroke Program Early CT Score and collateral status predict target mismatch in large vessel occlusion with delayed time windows
Conclusions NCCT ASPECTS had a strong correlation with CTP core volumes in patients with LVO-AIS in delayed time windows. Combining NCCT ASPECTS with sCTA-CS resulted in a more accurate prediction of target mismatch. If a CTP scan is not available, NCCT ASPECTS combined with sCTA-CS may guide clinicians in making treatment decisions.

Natural history, angiographic presentation and outcomes of anterior cranial fossa dural arteriovenous fistulas
Conclusion Most ACF-dAVFs have a symptomatic presentation. Drainage through cortical veins is a key angiographic feature of ACF-dAVFs that accounts for their malignant course. Microsurgery is the most effective treatment. Due to the high risk of bleeding, closure of ACF-dAVFs is indicated regardless of presentation.

O-012 Relationship between clot composition and procedural results for ischemic stroke aspiration thrombectomy: subset analysis from the INSIGHT registry
ConclusionsClot removed during neuroendovascular procedures can differ in consistency and removability, leading to an increased focus on thrombus composition as a crucial variable for improving outcomes of ischemic stroke. In this study, good final revascularization (mTICI 2b-3 at the final angiogram) occurred after aspiration thrombectomy regardless of clot composition. Ongoing analysis of collected specimens is expected to provide valuable information regarding thrombus biology and etiology and to aid in diagnosis, prognosis, and drug development.Abstract O-012 Table 1Clot composition vs procedural results for ischemic s...

O-017 Viz LVO versus rapid LVO in detection of large vessel occlusion on computed tomography angiography for acute stroke
ConclusionViz LVO and Rapid LVO had similar NPV, but Rapid LVO produced a significantly larger number of false positive values. False positive values can be a source of alarm desensitization, leading to missed alarms or delayed responses. EF and intracranial atherosclerosis were significant predictors of incorrect predictions in both software packages. We hope this data will be used to improve future algorithms.Disclosures A.

O-026 Incremental value of arterial spin labeling (ASL) over conventional MRI sequences in the detection of intracranial arteriovenous malformations in patients with hereditary hemorrhagic telangiectasia (HHT)
ConclusionsOur findings underscore the incremental value of ASL in addition to conventional MRI sequences as a screening tool in the detection of brain AVMs in patients with HHT. ASL was more sensitive than conventional contrast-enhanced MRI alone, potentially improving diagnostic accuracy in this patient population with many small AVMs. These findings further highlight the need for further research to explore the benefits of integrating ASL sequences into the initial evaluation and routine follow-up of patients with sporadic and HHT-related brain AVMs.Abstract O-026 Figure 1Disclosures W.

P-001 Residual in-stent carotid stenosis and cigarette smoking are predictors of restenosis after stenting (CAS)
ConclusionWe present the largest single-center data in the US to date on carotid artery stenosis treated with CAS, and factors associated with restenosis. Residual in-stent carotid stenosis and smoking history were independent predictors. Maximizing treatment of initial stenosis within stent for carefully selected patients and aggressive smoking cessation education are important steps in preventing future carotid restenosis.Abstract P-001 Figure 1Carotid restenosis after carotid arty tenting (%) by categories of degree of residual stenosis after initial procedure (a), and by cutpoint of 29% (b)Disclosures P.
