Cerebrospinal Fluid from Aneurysmal Subarachnoid Hemorrhage Patients Leads to Hydrocephalus in Nude Mice.

Neurocrit Care 2020 Jul 1. Epub 2020 Jul 1.

Department of Neurosurgery, University of Michigan, 3552 Taubman Center, 1500 E. Medical Center Drive, Ann Arbor, MI, 48109, USA.

Objective: Our prior studies have found that intracerebroventricular injection of blood components can cause hydrocephalus and choroid plexus epiplexus cell activation in rats. To minimize the cross-species reaction, the current study examines whether intraventricular injection of acellular components of cerebrospinal fluid (CSF) from subarachnoid hemorrhage patients can cause hydrocephalus and epiplexus macrophage activation in nude mice which lack a T cell inflammatory response.

Methods: Adult male nude mice received intraventricular injections of acellular CSF from subarachnoid hemorrhage patients or a control patient. Read More

BACKGROUND Cerebral arteriovenous malformations (AVMs) are considered to be abnormalities of congenital origin, presumably arising due to a disorder in the process of embryogenesis, in the phase of differentiation of premature vascular domes into mature arteries, capillaries, and veins. The end result of that process is the formation of direct arteriovenous communications, without intervening capillary beds. CASE REPORT We report the case of a 6-year-old female who suffered an abrupt deterioration of her level of consciousness due to a subarachnoid hemorrhage located in the basal cisterns. Read More

Department of Neurosurgery, National Institute of Mental Health and Neuro Sciences, Bengaluru, 560029, India.

Introduction: Diagnosis of the rupture of an intracranial aneurysm (IA) relies on sophisticated neuro-imaging studies, and molecular biomarkers to identify an IA or predict its rupture are still unavailable.

Objective: Our objective was to determine the plasma microRNA (miRNA) expression profile in patients with ruptured IA presenting as aneurysmal subarachnoid hemorrhage (aSAH) and identify potential biomarkers of aneurysmal rupture.

Methods: Plasma miRNA profiling was carried out using quantitative real-time polymerase chain reaction (qRT-PCR) in 20 patients with aSAH and 20 age- and sex-matched healthy controls. Read More

Optic Nerve Sheath Diameter is not Related to Intracranial Pressure in Subarachnoid Hemorrhage Patients.

Neurocrit Care 2020 Apr 21. Epub 2020 Apr 21.

Neuroscience Intensive Care Unit, Department of Anesthesia and Critical Care, Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico, Milan, Italy.

Background: Intracranial pressure (ICP) monitoring is essential after subarachnoid hemorrhage (SAH) to prevent secondary brain insults and to tailor individualized treatments. Optic nerve sheath diameter (ONSD), measured using ultrasound (US), could serve as a noninvasive bedside tool to estimate ICP, avoiding the risks of hemorrhage or infection related to intracranial catheters. The aims of this study were twofold: first, to explore the reliability of US for measuring ONSD; second, to establish whether the US-ONSD can be considered a proxy for ICP in SAH patients early after bleeding.
