E-020 Between a Rock and a Hard Place: The Use of Self-expanding Stents for the Endovascular Treatment of Acute Ischemic Stroke due to Recalcitrant Emergency Large Vessel Occlusion in the Era of Stent-retrievers: Single-center Experience and Early Results
ConclusionInitial results suggest that acute intracranial stenting may be beneficial in a subset of patients who present with an ELVO and who have failed recanalization by means of mechanical thrombectomy with stent-retrievers and/or thromboaspiration with large bore intracranial catheters.DisclosuresJ.

E-043 Reversible Cerebral Vasoconstriction Syndrome: Non-invasive Imaging Findings and Angiographic Evaluation
We present indirect findings on non-invasive imaging, such as transient cerebral edema, convexal subarachnoid hemorrhage, intraparenchymal hemorrhage and cerebral. Direct signs of single or multivessel arterial vasoconstriction are seen on CTA, MRA and confirmed on DSA. Reversibility of the vasoconstriction is demonstrated after intra-arterial administration of calcium channel blocker. Conditions such as diffuse atherosclerotic arterial narrowing, vasculitis, posterior reversible encephalopathy, cerebral edema secondary to venous congestion and vasospasm secondary to aneurysmal subarachnoid hemorrhage were among the pathol...
