E-045 Early neurological improvement is independent predictor of favorable outcome following thrombectomy for basilar artery occlusion
ConclusionENI is an independent predictor of favorable clinical outcome after BAO thrombectomy. Single pass successful recanalization is associated with higher likelihood of ENI.Disclosures S.

E-107 Carotid artery stenting in patients with symptomatic non-stenotic carotid artery disease - a case series
ConclusionsIn this case series performed over a 10-year period at a high-volume stroke center we show that CAS is safe and efficient in patients with SyNC. Previous studies have established safety and effectiveness of CES in patients presenting with SyNC, however there is a paucity of reports in the literature regarding the effect of CAS in this patient population. Recent guidelines have brought specific attention to high-risk plaque characteristics which suggest that plaque instability plays a major role in the onset of ischemic events, regardless of lumen narrowing. Advanced imaging techniques, such as Optical Coherence ...

O-025 The Superiority of Thrombectomy over IV rtPA Monotherapy May be Associated with Thrombus Length - Results of the THERAPY Trial
ConclusionExtensive thrombus burden presents a challenge for stroke intervention, posing greater risk of complications and poor clinical outcome. However, this effect is dampened when IAT is the interventional modality, leading to a more favorable prognosis over IV-rtPA alone. This study finding supports the use of aspiration thrombectomy in treatment of extended thrombi, demonstrating relative advantages over thrombolytic monotherapy, and enables better clinical outcomes.DisclosuresR. von Kummer: 2; C; Penumbra, Inc.

E-055 Endovascular Therapy for Patients with Acute Large MCA Territory Ischemia: Its Effect on the Risk of Subsequent Development of Deep Venous Thrombosis
ConclusionsIn patients with acute large MCA territory ischemia, endovascular recanalization therapy appeared to decrease the risk of developing subsequent DVT or PE. However, a larger sample size is needed to demonstrate statistical significance. Interestingly, majority of DVT were developed on the side of the extremity contralateral to the affected cerebral hemisphere.DisclosuresZ. Li: None. M. Cox: None.

Thromboembolic infarction caused by an unknown patent foramen ovale 30  years after VA shunt insertion: a case report and review of the literature
ConclusionsThromboembolic events due to a PFO are rare but possible life-threatening complication after VA shunt insertion. Therefore, preoperative cardiac diagnostic might be clinically relevant prior to a VA shunt implantation to avoid such complications.

P83 The relationship of functional outcome after mechanical thrombectomy and serum glucose is partially mediated by edema formation
ConclusionEdema formation explains 15% of the total adverse effects of high blood glucose levels. Major pathways might include other direct effects of high blood glucose, such as altered vessel wall and thrombus characteristics and higher thrombogenicity of the cerebral blood flow.ReferencesThorén, M., et al.

Early reperfusion and clinical outcomes in patients with M2 occlusion: pooled analysis of the PROACT II, IMS, and IMS II studies.
Conclusions A positive correlation between successful early reperfusion and clinical outcome could not be demonstrated for patients with M2 occlusion. Irrespective of reperfusion status, such patients have better outcomes than those with more proximal occlusions, with more than 50% achieving functional independence at 3 months.

E-127 intra-arterial thrombolysis for central retinal artery occlusion: a systematic review and meta-analysis
ConclusionIAT therapy for CRAO remains controversial. Pooled analysis of the retrospective studies supports IAT therapy whereas a single RCT does not support intervention. Other authors have suggested significant methodological concerns for the EAGLE study calling into question its conclusions that conflict with favorable studies of presumably lower levels of evidence.7 Additional study, potentially with stricter IAT time to treatment criteria may be warranted.ReferencesAhn SJ.
