E-015 Extra-Femoral Access for Mechanical Thrombectomy in Acute Ischemic Stroke
ConclusionsWhile trans-femoral access remains the mainstay for endovascular treatment of AIS, risk of vascular injury and delay of recanalization should alert the interventionalist to consider extra-femoral approaches. This case series demonstrates the safety and success possible with trans-radial or trans-cervical carotid catheterization in the setting of mechanical thrombectomy for AIS. With these findings, we feel strongly that further standardization of these techniques, guidelines for the need of extra-femoral access prospectively, and development of devices tailored for trans-radial and trans-cervical carotid approac...

E-024 Primary Intracranial Stenting for Refractory Reocclusion during Stent-Based Mechanical Thrombectomy for Acute Ischemic Stroke Intervention
ConclusionsThese results indicate that primary intracranial stenting for refractory re-occlusion during stent-based mechanical thrombectomy treatment in acute ischemic stroke is effective technique. Further studies are needed to evaluate long-term occlusion and in-stent stenosis.DisclosuresS. Sheen: None. J. Shin: None.

E-083 Acute Stroke Intervention for Large Vessel Occlusion with Combined Stent Retriever and Suction Thrombectomy (Solumbra Technique): A Retrospective Analysis of 85 Patients
ConclusionThe Solumbra technique compares favourably to other thrombectomy techniques used for acute stroke intervention. It achieved a TICI 2 B/3 reperfusion in 88% of patients, with an average number of 1.9 passes. Good functional outcome was achieved in 44% of patients on discharge, with a symptomatic intracranial hemorrhage rate of 4.7%.DisclosuresJ. Wong: None. N. Telischak: None. J. Heit: None. A.

Implications of limiting mechanical thrombectomy to patients with emergent large vessel occlusion meeting top tier evidence criteria
Conclusions Our study showed that with strict adherence to top tier evidence criteria, half of patients may not be considered for MT. Our data indicate no increased risk of sICH and a potentially higher mortality that is largely due to treatment of patients with basilar occlusions and those treated at an extended time window. Despite this, good functional recovery is possible, and consideration of MT in patients not meeting top tier evidence criteria may be warranted.

Mechanical thrombectomy in patients with medical contraindications for intravenous thrombolysis: a prospective observational study
Conclusions MT is safe in patients with potential comorbidity-derived risks that preclude IVT. MT should be offered, aiming for prompt recanalization, to patients with LVO stroke unsuitable for IVT. Trial registration number NCT02164357; Results.

Effectiveness of very low profile thrombectomy device in primary distal medium vessel occlusion, as rescue therapy after incomplete proximal recanalization or following iatrogenic thromboembolic events
Conclusion Direct or rescue MT of DMVO using a very low profile thrombectomy device is associated with a high rate of successful recanalization and a reasonable rate of symptomatic hemorrhagic complication, despite a risk of 18.1% hospital mortality in elderly patients. Further trials are needed to confirm our results and assess long-term clinical outcomes.

E-003 Safety and efficacy of balloon guide catheters in thrombectomy for anterior circulation stroke: a systematic review and meta-analysis
ConclusionBGC use during MT for acute ischemic stroke is associated faster to groin-to-recanalization times, improved TICI ≥2b reperfusion, lower incidence of sICH, and lower mortality. These data demonstrate the promise of BGC use for MT and warrant further study.Disclosures N. Shlobin: None. B. Jahromi: None. S. Ansari: None. M. Potts: None.

Postoperative occlusion degree after flow-diverter placement with adjunctive coiling: analysis of complications
Conclusions Although postoperative complete occlusion with a PED and adjunctive coiling can increase the rate of aneurysm occlusion, this approach may also increase the risk of ischemic stroke and lead to poor postoperative functional outcomes.

First-line thrombectomy strategy for anterior large vessel occlusions: results of the prospective ETIS egistry
Conclusions Despite high recanalization rates, our results question the safety of the combined approach, which was associated with disability and mortality. Randomized controlled trials are needed to evaluate the efficacy and safety of these techniques.

Multi-centric European post-market follow-up study of the Neuroform Atlas Stent System: primary results
Conclusions In this multicentric, prospective study, stent-assisted coiling of medium size unruptured aneurysms with the Neuroform Atlas stent resulted in a favorable rate of satisfactory occlusion. In our findings, the use of the Y-stenting technique was associated with increased rates of procedural complications. Clinical trial registration https://clinicaltrials.gov/ct2/show/NCT02783339.

P-031 End artery location of thrombus predicts poor neurological outcome despite successful thrombectomy for anterior circulation stroke
ConclusionsDespite similar vascular territories, concurrent occlusion of the MCA and ACA segments results in worse clinical outcomes compared to more proximal ICA occlusion. The likely explanation for fast progression of infarct in the MCA+ACA group is the higher likelihood of end-artery involvement and lower contribution of collateral flow. Reperfusion of both territories; however, does add to the risk of symptomatic post-procedural hemorrhage.Disclosures S. Eshraghi: None. S. Saperian: None. A. Alawieh: None. B. Howard: None. J.

E-156 Rescue stenting with self-expandable and balloon-mounted stents for acute large vessel stroke after failed mechanical thrombectomy presumable due to underlying intracranial atherosclerosis: systematic review
ConclusionOur study shows decent functional independence in patients with acute large vessel stroke who received any rescue stenting after failed mechanical thrombectomy presumable due to underlying intracranial atherosclerosis. The subgroup of patients who received SES presented the higher estimated pooled proportion of functional independence. Mortality, symptomatic intracranial hemorrhage, and all ICH were comparable in all groups. The study is limited by high heterogenicity, and unavailability of studies that directly compared to best medical treatment or a specific type of stent. Rescue stenting should be directly com...
