What is the impact of head movement on automated CT perfusion mismatch evaluation in acute ischemic stroke?
Conclusions Motion during CT perfusion acquisition influences automated mismatch evaluation. Potentially treatment-relevant changes in mismatch classifications in dependence of head movement were observed and occurred in favor of mechanical thrombectomy.

Definition and time course of pericavity edema after minimally invasive endoscopic intracerebral hemorrhage evacuation
Conclusions We present a detailed and accurate method for measuring PCE volume with semi-automatic, threshold-guided segmentation software in the postoperative patient with ICH. Decrease in PCE after MIS evacuation correlated with evacuation percentage, and relative PCE remained stable after minimally invasive endoscopic ICH evacuation.

EP35 7 T MR imaging of small incidental unruptured intracranial aneurysms: first year of clinical experience

O-020 Novel cone beam CT technology improves image quality for stroke assessment: a prospective series
ConclusionsThe latest generation of CB-CT scans & technology allow for exclusion of haemorrhages, stroke core definition and demonstration of brain perfusion and collaterals. These improvements suggest that CB-CT is acceptable for emergency stroke imaging assessment before mechanical thrombectomy, which may reduce door-to-groin puncture times and improve patient outcomes.ReferenceBourcier R, Goyal M, Liebeskind DS, et al.

O-030 Super-selective middle meningeal artery embolization for chronic subdural hematoma using n-BCA with the sugar push technique: single center experience of 61 consecutive patients
ConclusionMMA embolization using diluted n-BCA with concomitant Dextrose 5% injection (Sugar-Rush) is associated with a high degree of distal penetration and complete branch occlusion and minimal risk of cranial nerve palsy or other thrombo-embolic complications. Clinical trials are warranted to compare long-term efficacy of this procedure with standard of care management.Disclosures S. Majidi: None. S. Matsoukas: None. R. De Leacy: None. P.

P-019 Clinical significance of contrast staining after mechanical thrombectomy for acute ischemic stroke
ConclusionContrast staining is associated with the development of ICH, particularly in the early period after MT and worse clinical outcomes. While patients with ICH had worse functional outcomes at discharge, contrast staining itself was not associated with worse outcomes. Lasty, larger diameter clot retriever devices and catheters were not significantly correlated with the presence of contrast staining.Disclosures T. Lazaro: None. P. Cotton: None. C. English: None. K.

Successful recanalization in acute basilar artery occlusion treated with endovascular therapy is independent of thrombus length
Conclusions Successful recanalization does not depend on thrombus length in patients with BAO treated with EVT. Recanalization can therefore be achieved despite high clot burden. Additionally, a high density of thrombi was a strong predictor of a favorable outcome.

Impact of ASPECT scores and infarct distribution on outcomes among patients undergoing thrombectomy for acute ischemic stroke with the ADAPT technique
Conclusions Patients with moderate-sized core infarcts involving various distributions in either hemisphere can potentially achieve similar good outcomes compared with those with no core infarction at presentation. A treatment algorithm for acute ischemic stroke, which employs hardline ASPECTS thresholds or excludes patients with basal ganglia infarcts, might preclude patients who would potentially benefit from mechanical thrombectomy with ADAPT.
