E-228 Single center experience using 3mm trevo stent retrievers in medium vessel occlusion thrombectomy
ConclusionUse of 3mm Trevo NXT stent retriever in medium vessel occlusion for first line and rescue thrombectomy in our single center experience demonstrated an adequate safety and efficacy profile, thus endorsing its use in mechanical thrombectomy applications beyond large vessel occlusion cases. Future multicenter studies will build upon this initial experience to further characterize the utility of novel stent retrievers in medium vessel occlusions.Disclosures C. Zhao: None. M.

E-184 Transradial approach for pediatric diagnostic and neurointerventional surgery: single center case series and systematic review
ConclusionsOur results and the literature review demonstrate that the TRA is a safe and feasible option for pediatric patients. Routine use of ultrasound guidance, selection of appropriately sized catheters, and prophylactic use of vasodilators and antispasmodics can help ensure the success of the procedure and limit common access-site complications.Disclosures A.

O-042 Incidence of periprocedural stroke with radial access for diagnostic cerebral angiograms
ConclusionIn our experience, transradial access for diagnostic cerebral angiograms was associated with a low but not neglectable incidence of periprocedural strokes when compared to the traditional femoral approach. Patient vascular anatomy should be evaluated prior to selection of vascular access and patients should be made aware of the possibility of a slightly higher possibility of periprocedural stroke with transradial access.Abstract O-042 Table 1 Patient Age Access Vessels catheterized Catheter used Radial Medication Contrast Fluoro Time Platelet Count INR GFR COVID Status Stroke Symptoms NIHSS Imaging performed 1 5...

E-060 Endovascular treatment for intracranial giant cell arteritis with angioplasty, stenting, and intra-arterial calcium channel blockers
ConclusionsEndovascular treatment, including PTA (with or without stenting) and CCB infusion, may be effective in medically-refractory GCA with intracranial arterial stenosis but complication rates are considerable. The efficacy of CCB monotherapy implicates vascular smooth muscle dysfunction in the pathogenesis of intracranial GCA.Calcium-channel blocker infusion as monotherapy for intracranial giant cell arteritis. Pre-treatment angiography (lateral right internal carotid artery projection) shows severe focal supraclinoid ICA stenosis (curved white arrow, 1A). Post-verapamil infusion (20mg, 15 min delay) angiogram (1B) s...

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...

The detrimental clinical impact of severe angiographic vasospasm may be diminished by maximal medical therapy and intensive endovascular treatment
Conclusions An intensive endovascular approach of TBA and/or intra-arterial verapamil in combination with induced hypertension for severe aVSP may result in comparable clinical outcomes to those without vasospasm.

E-062 transradial access for acute interventional stroke therapy
ConclusionTransradial artery access for neuro-interventional procedures is rarely considered today. Our small case study suggests that transradial access is safe and efficacious in advance stroke therapy. Further studies with larger sample size are needed.DisclosuresJ. Farkas: None. K.
