P77 Predictors of good clinical outcome after thrombectomy for distal medium vessel occlusions
ConclusionAn older age, a longer puncture to recanalization time and a higher baseline core volume were strongly associated with poor clinical outcomes, while successful recanalization (mTICI 2c-3) was associated with better outcomes after MT for DMVO.ReferencesGuenego A, Mine B, Bonnet T, et al.

P78 How far is too far in stroke thrombectomy? From XL to XS vessel occlusions with radially adjustable stent-retrievers - Tigertriever XL and Tigertriever 13
ConclusionMechanical thrombectomy for both primary or secondary DMVO seems feasible and as safe as for LVO. Our initial experience using the Tigertriever13 is of special interest as it shows we can potentially significantly expand AIS population that can benefit from mechanical thrombectomy treatment.ReferencesGuenego A, Mine B, Bonnet T, et al.

E-044 Patient outcomes after treatment of brain aneurysm in small diameter vessels with the silk vista baby flow diverter: a systematic review
ConclusionThis systematic review suggests that SVB is a safe and effective treatment for intracranial aneurysms in small vessels. Device trackability and reduced system dimensions, also facilitated the treatment of previously judged not amenable lesions, including a wide range of aneurysms located in anterior and posterior circulation distal vessels. Further prospective and comparative studies with patient outcome data specific to aneurysm location are needed to confirm the safety and efficacy of SVB.Disclosures R.

O-007 First US multicenter experience using the pipeline flex embolization device with shield technology for treatment of intracranial aneurysms - periprocedural outcomes and early safety profile
ConclusionOur study is the first to report the early experience with the newly FDA-approved PED Flex with Shield technology amongst US centers. Our results are comparable with non-US, international studies showing a high technical success rate and safe peri-procedural angiographic and patient outcome. Long-term follow-up will be needed to provide more robust data on angiographic and patient outcomes.Disclosures A. Kuhn: None. J. Singh: None. A. Abdelsalam: None. V. Saini: None. J. Burks: None. G.

E-182 A multicentric experience for the use of flow diverter in the treatment of anterior communicating artery aneurysms
ConclusionFlow diverters appear to be a safe and effective treatment for anterior communicating artery aneurysms, presenting as an alternative strategy in the armamentarium of interventionalist. Mid-term results were favorable, and complication rates were low. Additional studies with longer follow-up time and independent adjudication are warranted to confirm the safety and effectiveness of the technique.Disclosures V. Benalia: None. G. Cortez: None. N.

O-038 Sympathetic nervous system activation causes cerebral perfusion deficit and cerebral vasoconstriction in Swine
ConclusionIn swine, electrical stimulation of SCG results in reproducible cerebral vasoconstriction and perfusion deficit comparable to cerebral vasospasm. This can be inhibited by prior local anesthetic injection into the SCG, a possible therapeutic target for cerebral vasospasm.Abstract O-038 Figure 1CT perfusion scan (top row) coronel view of approximate fronto-temporal area of swine brain (outlined in white box) at baseline, with right SCG stimulation, with lidocainc + right SCG stimulation.

P-013 Designing and prototyping a novel balloon-stent device for minimally invasive temporary aneurysm occlusion and embolization
ConclusionA balloon-stent device allows for longer neuro-interventional procedures by providing continuous perfusion without arresting blood flow during balloon inflation. In addition, this novel medical device provides a smooth surface at the aneurysm neck for consistent device placement, minimization of parent vessel trauma, elimination of ischemic effects distal to the parent artery, and minimization of intra-saccular flow remnants pre- and post-treatment.Abstract P-013 Figure 1a) FPR results from theoretical estimation, benchtop modeling, and computational fluid dynamic (CFD) simulation.
