Validation of a Mathematical Model for Rupture Status of Spherical Intracranial Aneurysms Open
Purpose An accurate mathematical model of intracranial aneurysm (IA) mechanics is of great value for its potential utility in assessing probability of IA rupture. Such a model for spherical IAs has been developed which predicts a wall-thic…

531 Novel inflammatory gene expression changes occur within the occluded vasculature of large vessel ischemic stroke Open
Objectives/Goals: We hypothesized that the bulk transcriptomic profiling of blood collected from within the ischemic vasculature during an acute ischemic stroke with large vessel occlusion (LVO) will contain unique biomarkers that are diff…

Tumor Embolic Stroke: The Importance of Pathological Assessment of Clots after Thrombectomy Open
While tumor emboli are a rare cause of stroke in cancer patients, they highlight the importance of gross observations and pathological assessments in the evaluation of clots. In this case report, a 70-year-old male with type 2 diabetes mel…

Abstract 068: Basilar artery bifurcation anatomy as a determinant of recanalization and stroke outcome Open
Introduction Background: Thrombectomy improves outcomes in patients with basilar artery (BA) occlusion [1,2]. We hypothesized that the anatomic configuration of the BA bifurcation, classified as T‐ or Y‐shaped, may impact the outcome. Spec…

Basilar artery recanalization by proximal balloon occlusion and aspiration in a single vessel vertebrobasilar system: A case report Open
The authors present a case of a patient with a hypoplastic right vertebral artery (VA) ending in the posterior inferior cerebellar artery who sustained an acute onset basilar artery occlusion. A balloon-guided catheter was used to proximal…

An algorithm to improve lateralization accuracy of inferior petrosal sinus sampling: procedural nuances for complex patterns of venous drainage. Patient series Open
BACKGROUND Inferior petrosal sinus sampling (IPSS) is a useful technique in the diagnosis of Cushing’s disease (CD) when the imaging finding is negative or equivocal. Different authors have reported considerable variability in the ability …

Transesophageal echocardiogram in the evaluation of acute ischemic stroke of young adults Open
INTRODUCTION: Acute ischemic stroke (AIS) in the young age (≤50 years) is a major cause of disability. The underlying mechanism of AIS in this age group is usually different from elderly. Transthoracic echocardiography (TTE) is used to det…
