556 Venous Sinus Stenting versus Ventriculoperitoneal Shunting: Comparing Treatment Costs for Idiopathic Intracranial Hypertension

Austin Michael Hilvert, Fatima Gauhar, Michael R. Longo, Anthony E. Bishay et autres

INTRODUCTION: Venous sinus stenting (VSS) has emerged as an effective treatment option for idiopathic intracranial hypertension (IIH), offering a less invasive alternative to traditional ventriculoperitoneal shunting (VPS). Prior studies have reported comparable efficacy between the two procedures, with some suggesting superior headache …

156 Comparative Analysis of Incidence and Hemorrhage Risk in Radiation-Induced versus Sporadic Cerebral Cavernous Malformations

Anthony E. Bishay, George W. Koutsouras, Alexander Lyons, Sujanaya Narayanan et autres

INTRODUCTION: Radiation-induced cerebral cavernous malformations (XRT-CCMs) are increasingly recognized as a late complication of cranial irradiation. While they share imaging features with sporadic CCMs (non-XRT-CCMs), early data suggest they may exhibit a more aggressive clinical course, particularly regarding hemorrhage risk and need …

Outcomes of venous sinus stenting versus ventriculoperitoneal shunting for fulminant idiopathic intracranial hypertension: a dual-center analysis

Lohit Velagapudi, Michael R. Longo, Austin Michael Hilvert, Fatima Gauhar et autres

OBJECTIVE: Venous sinus stenting (VSS) has emerged as a promising and less invasive treatment alternative to CSF diversion for patients with idiopathic intracranial hypertension (IIH). Fulminant IIH (fIIH) is a rare manifestation of IIH, affecting 2%-3% of IIH patients and characterized by …

Abstract 485: Outcomes of Mechanical Thrombectomy in Patients with Pre‐Stroke Disability: Subgroup Analysis from the EXCELLENT Registry

Nitin Goyal, Raul G. Nogueira, A. H. Siddiqui, Tommy B. Andersson et autres

Introduction Patients with pre‐existing disability, defined by a baseline modified Rankin Scale (mRS) score of 2‐4, are often excluded or underrepresented in mechanical thrombectomy (MT) clinical trials for acute ischemic stroke due to large vessel occlusions (LVOs). As MT becomes more widely …

The reactivity penumbra as a novel metric of ischemic symptomatology in patients with intracranial cerebrovascular disease

Caleb Han, Wesley T. Richerson, Maria Garza, Melanie Leguizamon et autres

Motivation: Quantitation of cerebrovascular reactivity (CVR) impairment from hypercapnic MRI stimuli is complicated by differences in imaging parameters, stimuli, and vendors. Goal(s): To evaluate if the volume of CVR impairment represents a reactivity penumbra that correlates directly with recent ischemic symptoms. Approach: …

Cerebrovascular Reactivity Response Times Following Revascularization Surgery in Patients with Moyamoya

Wesley T. Richerson, Alex A. Bhogal, Caleb Han, Maria Garza et autres

Motivation: Blood-oxygenation-level-dependent cerebrovascular reactivity (BOLD-CVR) is increasingly used to assay impairment in moyamoya disease, however BOLD-CVR response to surgery has not been fully characterized with a fixed inspiration stimulus. Goal(s): To fully characterize the temporal BOLD-CVR response to revascularization surgery in MMD …

Venous sinus stenting versus ventriculoperitoneal shunting: Comparing perioperative costs for idiopathic intracranial hypertension

Austin Michael Hilvert, Fatima Gauhar, M. J. Longo, Keyan A. Peterson et autres

IntroductionVenous sinus stenting (VSS) is an effective, less invasive alternative to ventriculoperitoneal shunting (VPS) for idiopathic intracranial hypertension (IIH). While efficacy is comparable, with some evidence favoring VSS for headache control, perioperative costs remain under-characterized due to reliance on reimbursement rates rather …

The hidden cost of being uninsured: Stroke mortality after mechanical thrombectomy

Alexander T. Lyons, Jordan Davis, Anthony E. Bishay, Akshay Bhamidipati et autres

INTRODUCTION: The impact of insurance status on mortality and functional outcomes has yet to be examined in Mechanical Thrombectomy (MT) patients, despite research on socioeconomic status. OBJECTIVE: Herein we describe the effects of insurance status on MT outcomes while controlling for other …

Fluoroscopic Shape and Pose Tracking of Catheters With Custom Radiopaque Markers

Jared Lawson, Rohan V Chitale, Nabil Simaan

Safe navigation of steerable and robotic catheters in the cerebral vasculature requires awareness of the catheter's shape and pose. Currently, a significant perception burden is placed on interventionalists to mentally reconstruct and predict catheter motions from biplane fluoroscopy images. Efforts to track …

Cost-Effectiveness Analysis of Early Minimally Invasive Removal of Intracerebral Hemorrhage

Janel Hanmer, Jonathan F. Arnold, Alex J. Hall, Jason W. Allen et autres

BACKGROUND: Supratentorial intracerebral hemorrhage (ICH) is common and often devastating. In a randomized controlled trial, ICH evacuation with minimally invasive trans-sulcal parafascicular surgery (MIPS) improved functional outcomes at 180 days compared with medical management (MM), primarily in patients with lobar hemorrhages. The …

280 A Transcriptome-Wide Association Study of Intracranial Aneurysm Identifies Novel Risk Genes and Overlapping Genetic Architecture With Other Vascular Disorders

Gunther W. Wong, Xavier Bledsoe, Eric R. Gamazon, Rohan V Chitale

INTRODUCTION: Intracranial aneurysms (IAs) are common cerebrovascular lesions with well-documented heritability. Numerous genome-wide association studies (GWAS) have attempted to define IA genetic architecture. However, linking individual risk SNPs from these studies to genes and causal pathways is challenging. To address this, transcriptome-wide …
