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...

INTRODUCTION: Aneurysmal subarachnoid hemorrhage (aSAH) is frequently seen in emergency departments. Secondary injury, such as subarachnoid hemorrhage-associated myocardial injury (SAHMI), affects one third of survivors and contributes to poor outcomes. SAHMI is not attributed to ischemia from myocardial disease but can result in hypotension and arrhythmias. It is important that emergency nurses recognize which clinical presentation characteristics are predictive of SAHMI to initiate proper interventions...

BACKGOUND AND IMPORTANCE: Idiopathic hypertrophic cranial pachymeningitis (IHCP) is a rare fibrosing inflammatory process involving the dura mater. Currently, there is no consensus on the treatments for IHCP, and the usefulness of immunosuppressive agents as a first-line option remains controversial. Cerebral venous sinus occlusion (CVSO) and cerebral venous sinus thrombosis (CVST) secondary to IHCP, which may cause progressive intracranial hypertension and venous obstructive parenchymal lesions, make the diagnosis and treatment of IHCP more complicated...

OBJECTIVE: The number of patients with non-aneurysmal subarachnoid hemorrhage (naSAH) has increased over the last decade. Data regarding infarctions in naSAH are still limited. Aim of the study was to identify the rate of cerebral vasospasm (CVS)-dependent and CVS-independent infarctions and their influence on clinical outcomes. METHODS: Between 1999 and 2015, 250 patients suffering from naSAH were analyzed retrospectively. A delayed infarction was analyzed whether it was associated with CVS (CVS-dependent infarction) or not (CVS-independent)...

Stroke is a devastating complication after intracranial aneurysm clipping. Understanding the risk factors that prognosticate perioperative stroke may help to identify patients that would benefit from neuroprotective therapy. This study assesses patient-specific independent predictors of perioperative stroke in relation to surgical aneurysm clipping. Additionally, this study evaluates the postoperative complications of stroke. We performed a retrospective chart review of 437 patients with ruptured and unruptured intracranial aneurysms, which underwent surgical clipping from 2006 to 2013...

BACKGROUND AND PURPOSE: The risk factors for intraprocedural rupture (IPR) of unruptured intracranial aneurysms (UIAs) and the outcomes of IPR itself are unclear. This study was performed to identify the independent risk factors for and outcomes of IPR. MATERIALS AND METHODS: We retrospectively evaluated the medical records and radiologic data of 1375 patients (1406 UIAs) who underwent coil embolization from January 2001 to October 2016. RESULTS: IPR occurred in 20 aneurysms of 20 patients (1...

BACKGROUND: Bilateral vertebral artery dissection (VAD) may result in subarachnoid hemorrhage (SAH). However, a variety of factors contribute to the difficulties with treating SAH. We report a case of bilateral VAD with SAH, as well as a literature review. CASE DESCRIPTION: A 32-year-old woman developed headache. Computed tomography (CT) demonstrated diffuse SAH, and 3-dimensional CT indicated bilateral VAD. Her left vertebral artery was severely stenosed and the basilar artery was retrogradely flowed via the posterior communicating artery...
