Secondary Ischemia Assessment in Murine and Rat Preclinical Subarachnoid Hemorrhage Models: A Systematic Review

Journal of the American Heart Association

BackgroundDelayed cerebral ischemia represents a significant contributor to death and disability following aneurysmal subarachnoid hemorrhage. The lack of standardized experimental setups and outcome assessments, particularly regarding secondary vasospastic/ischemic events, may be partly responsible for the translational failure.

Clinical Outcomes of Diffuse Angiogram?Negative Subarachnoid Hemorrhage Versus Aneurysmal Subarachnoid Hemorrhage: A Propensity Score?Matched Analysis

Journal of the American Heart Association

BackgroundThe outcome of diffuse angiogram‐negative subarachnoid hemorrhage (dan‐SAH) compared with aneurysmal SAH (aSAH) remains unclear. Propensity score matching resulted in matching 65 patients with dan‐SAH to 260 patients with aSAH, and clinical outcomes were compared between the groups. versus 0%,P=0.027), death (11.2%

Abstract WMP112: Neutrophil Extracellular Traps Occlude the Cerebrovasculature Causing Delayed Cerebral Ischemia After Subarachnoid Hemorrhage in Mice

Stroke Journal

Neutrophils are reported to be critical mediators of to poor outcome after subarachnoid hemorrhage (SAH). In this study, our hypothesis was that NETs cause vascular occlusion leading to delayed cerebral ischemia (DCI) and worse outcome after SAH. However, degrading NETs only marginally improved outcomes.

Abstract 087: Cocaine?Induced Acute Spinal Cord Ischemia Syndrome

Stroke: Vascular and Interventional Neurology

IntroductionAcute spinal cord ischemia syndrome (ASCIS) is a rare disease that is thought to comprise roughly only 1.2% The use of recreational cocaine in young adults is well known to be responsible for acute ischemic and hemorrhagic strokes in individuals who lack other vascular risk factors. of all strokes [1, 2].

Abstract TP169: Cannabidiol as a Therapy for Experimental Subarachnoid Hemorrhage

Stroke Journal

Subarachnoid hemorrhage (SAH), commonly caused by a ruptured aneurysm, carries a high rate of disability and death. Preclinical studies demonstrate SAH induces dysregulation of the cerebrovasculature and increases neuroinflammation, which contributes to early brain injury and delayed cerebral ischemia.

Abstract TP303: Perfluorocarbon Oxygent Limits Functional Impairment and Brain Damage Following Subarachnoid Hemorrhage

Stroke Journal

Introduction:Subarachnoid hemorrhage (SAH) is the deadliest form of hemorrhagic stroke. Post-SAH vasospasm induces brain tissue hypoxia-ischemia resulting in brain injury and functional impairments. At 48h after SAH, mice were tested for functional outcomes followed by blood collection through cardiac puncture.

Abstract 114: LACROSSE Trial: Lumbar Drainage Compared to External Ventricular Drainage in Aneurysmal Subarachnoid Hemorrhage, a Randomized Control Trial

Stroke Journal

Introduction:Delayed cerebral ischemia (DCI) is a leading cause of morbidity and mortality in aneurysmal subarachnoid hemorrhage (aSAH). The primary outcome was DCI, defined as an exclusionary change in GCS or new, none-treatment related infarcts on imaging. Stroke, Volume 55, Issue Suppl_1 , Page A114-A114, February 1, 2024.
