The Prognostic Value of CT-Angiographic Parameters After Reperfusion Therapy in Acute Ischemic Stroke Patients With Internal Carotid Artery Terminus Occlusion: Leptomeningeal Collateral Status and Clot Burden Score
The objective of this study was to investigate the prognostic value of computed tomographic angiography (CTA) based on leptomeningeal collateral (LMC) status and other parameters in acute ischemic stroke (AIS) patients with internal carotid artery (ICA) terminus occlusion treated with endovascular treatment (EVT).

Angiographic Blush after Mechanical Thrombectomy is Associated with Hemorrhagic Transformation of Ischemic Stroke
Risk factors for hemorrhagic transformation of ischemic stroke after mechanical thrombectomy (MT) are not well established. We conducted a study to determine if prominent angiographic cerebral vascularity following recanalization with thrombectomy (angiographic blush) is associated with hemorrhagic transformation.

Collateral status reperfusion and outcomes after endovascular therapy: insight from the Endovascular Treatment in Ischemic Stroke (ETIS) Registry
Conclusions Collateral status predicted functional outcome after EVT. However, collateral status on the pretreatment angiogram did not decrease the clinical benefit of successful reperfusion.

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.

Stroke Dysbiosis Index (SDI) in Gut Microbiome Are Associated With Brain Injury and Prognosis of Stroke
Conclusions: We developed an index to measure gut microbiota dysbiosis in stroke patients; this index was significantly correlated with patients' outcome and was causally related to outcome in a mouse model of stroke. Our model facilitates the potential clinical application of gut microbiota data in stroke and adds quantitative evidence linking the gut microbiota to stroke. Introduction Ischemic stroke imposes a heavy burden on society, with 24.9 million cases worldwide (1). Although intravenous thrombolysis and endovascular treatment greatly improve some patients' prognosis, the prognosis for most pa...

Intravenous Thrombolysis in Posterior Circulation Stroke
Conclusions: Up to date, no data about PCIS and IVT are available from RTCs. Based on limited results from retrospective clinical studies and case series, IVT is safer for use in PCIS than in ACIS. Patients with brainstem ischemia, vertebral artery occlusion, and absence of basilar or posterior cerebral artery occlusion could be considered for treatment with IVT even in borderline cases. Time to IVT in PCIS seems to be a less crucial factor than in ACIS. IVT for PCIS may be beneficial even after 4.5 h from symptom onset.

Postreperfusion Blood Pressure Variability After Endovascular Thrombectomy Affects Outcomes in Acute Ischemic Stroke Patients With Poor Collateral Circulation
Conclusion: Postreperfusion BP management by decreasing BPV may have influence on improving clinical outcome in cases of poor collateral circulation among patients achieving successful recanalization after ERT. Introduction Endovascular recanalization therapy (ERT) has been adopted as standard stroke care in patients with acute ischemic stroke (1–6). Time to recanalization and degree of recanalization are the most important predictors of clinical outcomes after ERT (7). Before recanalization, an effort to reduce the time from symptom onset to reperfusion is critical for penumbral salvage. After recanalization...

Conveniently-Grasped Field Assessment Stroke Triage (CG-FAST): A Modified Scale to Detect Large Vessel Occlusion Stroke
Conclusions: CG-FAST scale could be an effective and simple scale for accurate identification of LVOS among AIS patients. Introduction Large vessel occlusion stroke (LVOS) often leads to severe disability and mortality. Although endovascular therapy (EVT) has been proved to be effective for LVOS patients (1–9), especially in anterior circulation, its benefit is highly time-dependent (10, 11). As hospitals with around-the-clock endovascular capability are scarce in many parts of the world and patients admitted directly to a CSC would have better outcomes than those receiving drip and ship treatment (12, 13), t...

Propensity Score-Matched Analysis of Lesion Patterns in Stroke Patients With Patent Foramen Ovale and Patients With Spontaneous Intracranial Artery Dissection
Conclusion: The present study suggests that lesion patterns observed from DWI of patients with PFO and SIAD might provide clues to the etiology of infarcts. Single lesions (cortical or subcortical) might be a typical feature of PFO associated strokes, while multiple lesions in one vascular territory might be a specific feature of SIAD associated strokes. Introduction Both patent foramen ovale (PFO) and spontaneous intracranial artery dissection (SIAD) are important stroke risk factors, especially in young and middle-aged adults (1–3). About 25% of patients with ischemic stroke are cryptogenic (4), and PFO is ...

Cardiac Imaging Within Emergency CT Angiography for Acute Stroke Can Detect Atrial Clots
This study was approved by the ethics committee of the medical faculty of the Ruhr University Bochum. FIGURE 1 Figure 1. Flow chart showing the selection of the study population. Results A total of 59 patients underwent emergency CCTA (Figure 2A) for suspected stroke, of which 44 received the final diagnosis ischemic stroke. There were 17 patients who had ischemic stroke or TIA and known or newly diagnosed atrial fibrillation (Table 1; mean age: 77.5 years, standard deviation: 8.4 years; 53% female). As hypothesized, intracardiac thrombi could be visualized: once in an artificially occluded left atrial appe...

Ischemic Stroke Outcomes in Oman: Experience of a University Hospital Based Stroke Registry (P6.278)
Conclusions:Ischemic stroke in Oman reflects the high morbidity/mortality seen in most communities in the region. Characteristics of incident stroke such as stroke recurrence, type, severity and cardiovascular comorbidity are likely the major determinants of stroke outcome. A relatively lower prevalence of extracranial artery disease and possible greater prevalence of multiple stroke mechanisms may also influence on outcomes and merit further study.Disclosure: Dr. Gujjar has nothing to disclose.

Status epilepticus mimicking stroke recurrence.
CONCLUSION: Status epilepticus is not infrequent in patients with previous stroke and may present with negative neurological symptoms, thus mimicking a stroke recurrence. EEG should be considered as a potential diagnostic tool in the acute stroke setting, at least in patients with previous stroke. This article is part of the Special Issue "Seizures & Stroke".

E-021 Pathophysiology, stroke types, collateral formation and aneurysms in moyamoya disease/moya moya syndrome
ConclusionsMMD is presented most commonly with ischemic stroke in the pediatric age group and with hemorrhagic stroke in the adult age group. MMD-associated intracranial aneurysms frequently occur in patients presenting with hemorrhagic unilateral MMD and are associated with an extremely high rate of rupture. Long-standing hemodynamic stress might contribute to the formation of an aneurysm.Disclosures S. Ahmad: None.

Patient-Specific Modeling Could Predict Occurrence of Pediatric Stroke
Moyamoya disease (MMD) is a progressive steno-occlusive cerebrovascular disease leading to recurrent stroke. There is a lack of reliable biomarkers to identify unilateral stroke MMD patients who are likely to progress to bilateral disease and experience subsequent contralateral stroke(s). We hypothesized that local hemodynamics are predictive of future stroke and set out to noninvasively assess this stroke risk in pediatric MMD patients. MR and X-ray angiography imaging were utilized to reconstruct patient-specific models of the circle of Willis of six pediatric MMD patients who had previous strokes, along with a control s...
