PURPOSE: In patients with aneurysmal subarachnoid hemorrhage (aSAH), acute cardiac dysfunction and triple-H-therapy, can lead to hypoxemia. Our aim was to assess impact of a protocoled fluid restrictive approach on hypoxemia in these patients. METHODS: We included prospectively ICU patients with aSAH admitted within 24h after the bleed. The study was divided into 2 phases. The first phase, from January to December 2012, was designated as control group (group C)...

BACKGROUND: Endovascular coil embolization and craniotomy with clip ligation are the two most commonly used treatments for ruptured cerebral aneurysm. While coiling maintains the advantages of brevity and complete avoidance of brain retraction and manipulation, clipping offers the benefits of decompression of the injured brain and lower aneurysm recurrence rates. A combined, immediately sequential treatment strategy for acutely ruptured cerebral aneurysm that simultaneously maximizes the advantages of both techniques, while minimizing their respective disadvantages, may be a useful paradigm...

OBJECTIVE Recent observational data suggest that ultra-early treatment of ruptured aneurysms prevents rebleeding, thus improving clinical outcomes. However, advances in critical care management of patients with ruptured aneurysms may reduce the rate of rebleeding in comparison with earlier trials, such as the International Cooperative Study on the Timing of Aneurysm Surgery. The objective of the present study was to determine if an ultra-early aneurysm repair protocol will or will not significantly reduce the number of incidents of rebleeding following aneurysmal subarachnoid hemorrhage (SAH)...

Postmortem computed tomography (PMCT) of the brain has an important role in detection of subarachnoid hemorrhage (SAH), which has a high mortality rate. However, a phenomenon known as "pseudo-SAH," or high-attenuation areas along the cisterns mimicking SAH, may be seen on CT. The aim of this study was to evaluate the diagnostic accuracy of brain PMCT for SAH and to identify the characteristics of pseudo-SAH. Findings on PMCT (sulcal effacement, asymmetry, maximum thickness of SAH signs, presence of acute/subacute intraventricular/intraparenchymal hemorrhage) and clinical history (left ventricular assist device [LVAD] implantation, anticoagulation therapy/coagulation disorder, global ischemia) were compared between subjects with true SAH and those with pseudo-SAH...

Subarachnoid hemorrhage (SAH) is a common and frequently life-threatening cerebrovascular disease, which is mostly related with a ruptured intracranial aneurysm. Its complications include rebleeding, early brain injury, cerebral vasospasm, delayed cerebral ischemia, chronic hydrocephalus, and also non neurological problems. Non-coding RNAs (ncRNAs), comprising of microRNAs (miRNAs), small interfering RNAs (siRNAs) and long non-coding RNAs (lncRNAs), play an important role in intracranial aneurysms and SAH. Here, we review the non-coding RNAs expression profile and their related mechanisms in intracranial aneurysms and SAH...

RATIONALE: Little is known about optic radiation (OR) injury following aneurysmal subarachnoid hemorrhage (SAH). In the current study, we report on a patient who showed a visual field defect and injury of the OR following aneurysmal SAH, using diffusion tensor tractography (DTT). PATIENT CONCERNS: At 4 weeks from onset, when a 62-year old female started rehabilitation, she complained of a visual field defect. Peripheral field defects were detected on both eyes using the Humphrey visual field test...

A 55-year-old man presented with difficulty breathing, chest pain, and disturbance of consciousness, and was transferred to our hospital. Initial whole body CT revealed a diffuse subarachnoid hemorrhage(SAH)with severe pulmonary edema that was considered neurogenic in origin. He received controlled ventilation under sedation and conservative care for the SAH. One day after the onset of the SAH, his left pupil suddenly became dilated to 6mm, with no reaction to light. Head CT showed no new bleeding. Subsequent CT angiogram revealed a right internal carotid-posterior communicating artery aneurysm(IC-PC AN)with a posterior-lateral projection; however, no vessel abnormality was observed in the left anterior or posterior circulations...

BACKGROUND: Heparanase, a mammalian endo-β-D-glucoronidase that specifically degrades heparan sulfate, has been implicated in inflammation and ischemic stroke. However, the role of heparanase in neuroinflammatory response in subarachnoid hemorrhage (SAH) has not yet been investigated. This study was designed to examine the association between heparanase expression and neuroinflammation during subarachnoid hemorrhage. METHODS: Rats were subjected to SAH by endovascular perforation, and the expression of heparanase was determined by Western blot analysis and immunofluorescence in the ipsilateral brain cortex at 24 h post-SAH...

Recent genome-wide association studies (GWAS) have identified numerous single nucleotide polymorphisms (SNPs) associated with coagulation system, including hemostatic factors and hematological phenotypes. However, few articles described the relationships between these SNPs and the risk of hemorrhagic stroke. The aim of our study was to evaluate the roles of these SNPs as risk factors and survival predictors for hemorrhagic stroke. Thirteen SNPs from GWAS in coagulation system were genotyped in a Chinese Han population including 1000 patients with hemorrhagic stroke (intracerebral hemorrhage, ICH = 743; subarachnoid hemorrhage, SAH = 257) and 1044 population-based controls...

The pathogenesis of cerebral/renal salt-wasting syndrome remains unknown. We herein present a case of salt-wasting syndrome with a natural killer-cell neoplasm without cerebral invasion. A 78-year-old man with hemophagocytic syndrome received two cycles of chemotherapy that did not induce tumor lysis syndrome, but repeatedly caused polyuria and natriuresis. The expression of tumor necrosis factor-α in the neoplasm led us to hypothesize that an oncolysis-induced cytokine storm may have caused renal tubular damage and salt wasting...

Aneurysm rebleeding following initial endovascular management is uncommon, and the factors associated with its occurrence are poorly defined. We retrospectively analyzed a consecutive series of patients presenting with aneurysmal subarachnoid hemorrhage who underwent endovascular management to determine factors associated with rebleeding. Rebleeding occurred in 7/183 (3.8%) patients, 6 of which had an adjacent hematoma on initial neuroimaging. Aneurysms were located on the ACoA (n=5), PCoA (n=1), and MCA (n=1)...

BACKGROUND: If acute severe headache disappears early after its onset, the question arises whether subarachnoid hemorrhage (SAH) should still be ruled out. We studied the initial time-course and minimal duration of headache in a consecutive series of neurologically intact patients with spontaneous SAH. METHODS: We included patients admitted between 2012 and 2015 within 48h after spontaneous SAH with a normal level of consciousness and no focal deficits. We retrieved data on headache severity, measured with a Numeric Rating Scale (NRS), <48h after ictus...

BACKGROUND: Hemangioblastomas (HGBs) are the most common primary intra-axial posterior fossa tumor in adults. Although spontaneous hemorrhage of these tumors is exceedingly rare, despite their vascular nature, we describe a case of recurrent hemorrhage with associated tonsillar herniation, and demonstrate that a surgical approach can provide a suitable outcome. CASE DESCRIPTION: A 54-year-old female with von Hippel-Lindau (VHL) syndrome presented with acute loss of consciousness and Glasgow Coma Scale (GCS) was 4...

OBJECT: Posterior inferior cerebellar artery (PICA) aneurysms are heterogeneous, uncommon lesions that can be treated in many fashions. Many previous series have focused on a specific aneurysm subset or treatment paradigm. The aim of this study was to present a comprehensive approach for all PICA aneurysms and analyze outcomes by PICA location. METHODS: All PICA aneurysms treated from 2012 until present were reviewed retrospectively and classified by location. Angiographic and clinical outcome were assessed...

BACKGROUND: Clopidogrel/aspirin antiplatelet therapy is routinely administered 7 to 10 days prior to pipeline aneurysm treatment. Our study assessed the safety and efficacy of a 600mg loading dose of clopidogrel 24 hours before PED treatment. METHODS: We performed a retrospective cohort study involving patients treated with pipeline from October 2010 to May 2016. 39.7%(n=158) patients were dispensed a loading dose of 650mg of aspirin plus at least 600mg of clopidogrel 24 hours preceding PED deployment; 60...
