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. In murine studies (n=30), the endovascular perforation model was predominantly used, while rat studies primarily employed intracisternal blood injection to mimic subarachnoid hemorrhage.

ECG Changes in Intracranial Hemorrhage

All About Cardiovascular System and Disorders

ECG Changes in Intracranial Hemorrhage ECG changes are fairly common in intracranial hemorrhage. Giant T inversions with QT interval prolongation may be seen in intracranial hemorrhage even without associated myocardial damage [1]. But the number of persons with lobar hemorrhage in that study was only 17%. Am Heart J.

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.

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. 60.12];P=0.042), or delayed cerebral ischemia (12.3% 4.64];P<0.001), presence of intraventricular hemorrhage (OR, 3.58 [95% CI, 1.72–7.46];P=0.001), versus 0%,P=0.027), death (11.2%

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. Stroke, Volume 55, Issue Suppl_1 , Page ATP303-ATP303, February 1, 2024.
