Catheter based selective hypothermia reduces stroke volume during focal cerebral ischemia in swine
Conclusions Selective moderate hypothermia was rapidly induced using endovascular techniques in a clinically realistic swine stroke model. A significant reduction in stroke volume on MRI was observed. Endovascular selective hypothermia can provide neuroprotection within time frames relevant to acute ischemic stroke treatment.

P-008 Evaluating Racial/Ethnic Disparity in Endovascular Thrombectomy Outcome for Acute Stroke Patients: 4,763 patients using Premier data 2011 to 2015
ConclusionsThere were no differences in hospital outcome among races/ethnicities in endovascular thrombectomy outcomes for acute stroke patients in the Premier data. Racial/ethnic disparities play role for patients’ selection not for patients’ outcome in endovascular thrombectomy.DisclosuresS. Park: None. M. Pilot: None. M.

O-031 Combinational therapy following elvo in a mouse model of stroke demonstrates new frontiers in neuroprotection: the mavaric trial
Stroke remains a leading cause of morbidity and mortality in the United States. Potential therapies have encountered significant barriers in attempts to translate bench to bedside research. Because of this, we have evaluated novel roles for FDA approved drugs, repurposed for treating stroke. Two such drugs, verapamil and magnesium, represent drug classes with a long history in neuroprotection trials with mixed results. Using an intra-arterial (IA) model developed in our lab, we selectively delivered our agents of interest to the stroke affected region following experimental stroke and successful recanalization. In addition...

E-095 Pre hospital stroke notification and prospective 90-day functional outcome in community hospital
Conclusion In a prospective community sample those who received IVtpa and those with milder NIHSS had significantly better 90 day mRS outcomes. Pre hospital stroke notification in itself did not result in better functional or quality of life outcomes at 90 days in this community setting. Disclosures: B. Klein: None. N. Adler: None. R.

Automated emergent large vessel occlusion detection by artificial intelligence improves stroke workflow in a hub and spoke stroke system of care
Conclusions AI automated alerts can be incorporated into a comprehensive stroke center hub and spoke system of care. The use of AI to detect ELVO improves clinically meaningful stroke workflow metrics, resulting in faster treatment times for mechanical thrombectomy.

P-006 The 'hub-spoke telemedicine model in a large cohort of stroke patients
ConclusionTele-stroke networks have proven to be a pivotal development in the treatment of strokes, especially those that are remote. With the additional expertise and the shorter duration from onset to diagnosis to treatment, these networks have substantially improved patient care and decreased healthcare costs, avoiding unnecessary transfers from spoke hospitals to hub.Abstract P-006 Figure 1Abstract P-006 Figure 2Disclosures K.

O-035 The Dotter Technique Revisited: Early Experience using this Technique for Treating Tandem Lesions in Acute Stroke
Conclusion The Dotter Stroke technique is a safe alternative to carotid stenting, and may be useful in patients at increased risk for haemorrhage. In this small series, a post-Dotter stenosis >75% is associated with re-occlusion, and stenting should be performed to prevent re-occlusion. No re-occlusion was identified at 30 days with post-Dotter stenosis <= 65%. Disclosures B. Woodward: None. E. Nyberg: None. S. Wegryn: None.
