Abstract
Introduction Hyperglycemia is a marker of poor prognosis in severe brain injuries. There is currently little data regarding the effects of intensive insulin therapy (IIT) on neurological recovery. Methods A sub-group analysis of the randomized-controlled CGAO-REA study (NCT01002482) in surgical intensive care units (ICU) of two university hospitals. Patients with severe brain injury, with an expected ICU length of stay ≥48 hours were included. Patients were randomized between a conventional glucose management group (blood glucose target between 5.5 and 9 mmol.L−1) and an IIT group (blood glucose target between 4.4 and 6 mmol.L−1). The primary outcome was the day-90 neurological outcome evaluated with the Glasgow outcome scale. Results A total of 188 patients were included in this analysis. In total 98 (52%) patients were randomized in the control group and 90 (48%) in the IIT group. The mean Glasgow coma score at baseline was 7 (±4). Patients in the IIT group received more insulin (130 (68 to 251) IU versus 74 (13 to 165) IU in the control group, P = 0.01), had a significantly lower morning blood glucose level (5.9 (5.1 to 6.7) mmol.L−1 versus 6.5 (5.6 to 7.2) mmol.L−1, P <0.001) in the first 5 days after ICU admission. The IIT group experienced more episodes of hypoglycemia (P <0.0001). In the IIT group 24 (26.6%) patients had a favorable neurological outcome (good recovery or moderate disability) compared to 31 (31.6%) in the control group (P = 0.4). There were no differences in day-28 mortality. The occurrence of hypoglycemia did not influence the outcome. Conclusions In this sub-group analysis of a large multicenter randomized trial, IIT did not appear to alter the day-90 neurological outcome or ICU morbidity in severe brain injured patients or ICU morbidity.

Abstract
Purpose An intracranial aneurysm, with or without subarachnoid hemorrhage (SAH), is a relevant health problem. The rupture of an intracranial aneurysm is a critical concern for individual health; even an unruptured intracranial aneurysm is an anxious condition for the individual. The aim of this guideline is to present current and comprehensive recommendations for the management of intracranial aneurysms, with or without rupture. Materials and Methods We performed an extensive literature search, using Medline. We met in person to discuss recommendations. This document is reviewed by the Task Force Team of the Korean Society of Interventional Neuroradiology (KSIN). Results We divided the current guideline for ruptured intracranial aneurysms (RIAs) and unruptured intracranial aneurysms (UIAs). The guideline for RIAs focuses on diagnosis and treatment. And the guideline for UIAs focuses on the definition of a high-risk patient, screening, principle for treatment and selection of treatment method. Conclusion This guideline provides practical, evidence-based advice for the management of patients with an intracranial aneurysm, with or without rupture.

Abstract
BACKGROUND AND PURPOSE Delayed cerebral ischemia and vasospasm are significant complications following SAH leading to cerebral infarction, functional disability, and death. In recent years, CTA and CTP have been used to increase the detection of delayed cerebral ischemia and vasospasm. Our aim was to perform comparative-effectiveness and cost-effectiveness analyses evaluating CTA and CTP for delayed cerebral ischemia and vasospasm in aneurysmal SAH from a health care payer perspective. MATERIALS AND METHODS We developed a decision model comparing CTA and CTP with transcranial Doppler sonography for detection of vasospasm and delayed cerebral ischemia in SAH. The clinical pathways were based on the "Guidelines for the Management of Aneurysmal Subarachnoid Hemorrhage: A Guideline for Healthcare Professionals from the American Heart Association/American Stroke Association" (2012). Outcome health states represented mortality and morbidity according to functional outcomes. Input probabilities of symptoms and serial test results from CTA and CTP, transcranial Doppler ultrasound, and digital subtraction angiography were directly derived from an SAH cohort by using a multinomial logistic regression model. Expected benefits, measured as quality-adjusted life years, and costs, measured in 2012 US dollars, were calculated for each imaging strategy. Univariable, multivariable, and probabilistic sensitivity analyses were performed to determine the independent and combined effect of input parameter uncertainty. RESULTS The transcranial Doppler ultrasound strategy yielded 13.62 quality-adjusted life years at a cost of $154,719. The CTA and CTP strategy generated 13.89 quality-adjusted life years at a cost of $147,097, resulting in a gain of 0.27 quality-adjusted life years and cost savings of $7622 over the transcranial Doppler ultrasound strategy. Univariable and multivariable sensitivity analyses indicated that results were robust to plausible input parameter uncertainty. Probabilistic sensitivity analysis results yielded 96.8% of iterations in the right lower quadrant, representing higher benefits and lower costs. CONCLUSIONS Our model results suggest that CTA and CTP are the preferred imaging strategy in SAH, compared with transcranial Doppler ultrasound, leading to improved clinical outcomes and lower health care costs.

Abstract
OBJECTIVE To report the case of an angiography-negative subarachnoid hemorrhage (SAH) in association with increased use of the sympathomimetic phentermine. SUMMARY A 45-year-old woman taking phentermine for weight loss presented with the "worst headache of her life," as well as nausea and some confusion. Her prior medical history was largely negative for pathology except for a 20-pack-year history of smoking. RESULTS Upon admission to an inpatient facility, the patient was normotensive with a Glasgow Coma Score of 15. She was found on computed tomography to have a diffuse SAH (Hunt and Hess grade 2, Fisher grade 3). Digital subtraction angiography, performed on hospital day 2, was negative for aneurysm. The patient convalesced in the intensive care unit for 8 days and was treated as a typical patient with SAH (i.e., vasospasm prophylaxis with nimodipine and atorvastatin, ad lib diet with strict attention to fluid balance to maintain euvolemia). A repeat angiographic study on hospital day 8 also did not reveal an aneurysm or other cause for her SAH. She was discharged thereafter with intensive smoking cessation education and counseled to discontinue phentermine. Upon follow-up 6 weeks later, the patient was without complaints or neurologic deficits and had resumed her previous activities and work. CONCLUSION Phentermine is a sympathomimetic agent found commonly in weight-loss products. Sympathomimetics have been linked to the development of hypertension, which can lead to cardiovascular and neurologic hemorrhages. We believe that the SAH in this patient was likely secondary to drug-induced hypertension or vasculopathy from the phentermine.

The 'Sphere': A Dedicated Bifurcation Aneurysm Flow-Diverter Device. Cardiovasc Eng Technol 2014; 5:334-347.

Abstract
We present flow-based results from the early stage design cycle, based on computational modeling, of a prototype flow-diverter device, known as the 'Sphere', intended to treat bifurcation aneurysms of the cerebral vasculature. The device is available in a range of diameters and geometries and is constructed from a single loop of NITINOL® wire. The 'Sphere' reduces aneurysm inflow by means of a high-density, patterned, elliptical surface that partially occludes the aneurysm neck. The device is secured in the healthy parent vessel by two armatures in the shape of open loops, resulting in negligible disruption of parent or daughter vessel flow. The device is virtually deployed in six anatomically accurate bifurcation aneurysms: three located at the Basilar tip and three located at the terminus bifurcation of the Internal Carotid artery (at the meeting of the middle cerebral and anterior cerebral arteries). Both steady state and transient flow simulations reveal that the device presents with a range of aneurysm inflow reductions, with mean flow reductions falling in the range of 30.6-71.8% across the different geometries. A significant difference is noted between steady state and transient simulations in one geometry, where a zone of flow recirculation is not captured in the steady state simulation. Across all six aneurysms, the device reduces the WSS magnitude within the aneurysm sac, resulting in a hemodynamic environment closer to that of a healthy vessel. We conclude from extensive CFD analysis that the 'Sphere' device offers very significant levels of flow reduction in a number of anatomically accurate aneurysm sizes and locations, with many advantages compared to current clinical cylindrical flow-diverter designs. Analysis of the device's mechanical properties and deployability will follow in future publications.

Abstract
OBJECTIVE Subarachnoid hemorrhage (SAH) is a particularly devastating type of stroke which is responsible for one third of all stroke-related years of potential life lost before age 65. Surgical treatment has been shown to decrease both morbidity and mortality after subarachnoid hemorrhage. We hypothesized that payer status other than private insurance is associated with lower allocation to surgical treatment for patients with SAH and worse outcomes. DESIGN We examined the association between insurance type and surgical treatment allocation and outcomes for patients with SAH while adjusting for a wide range of patient and hospital factors. We analyzed the Nationwide Inpatient Sample hospital discharge database using survey procedures to produce weighted estimates representative of the United States population. PATIENTS We studied 21047 discharges, representing a weighted estimate of 102595 patients age 18 and above with a discharge diagnosis of SAH between 2003 and 2008. MEASUREMENTS Multivariable logistic and generalized linear regression analyses were used to assess for any associations between insurance status and surgery allocation and outcomes. MAIN RESULTS Despite the benefits of surgery 66% of SAH patients did not undergo surgical treatment to prevent rebleeding. Mortality was more than twice as likely for patients with no surgical treatment compared to those who received surgery. Medicare patients were significantly less likely to receive surgical treatment. CONCLUSIONS Nearly two thirds of patients with SAH don't receive operative care, and Medicare patients were significantly less likely to receive surgical treatment than other patients. Bias against the elderly and those with chronic illness and disability may play a part in these findings. A system of regionalized care for patients presenting with SAH may reduce disparities and improve appropriate allocation to surgical care and deserves prospective study.

Abstract
BACKGROUND Readmission within 30 days is increasingly evaluated as a measure of quality of care. There are few data on the rates of readmission after subarachnoid hemorrhage (SAH). OBJECTIVE We sought to determine the predictors of 30-day readmission in patients with SAH. METHODS We prospectively identified 283 patients with SAH admitted between 2006 and 2012. Readmission was determined by means of an automated query with confirmation in the electronic medical record. RESULTS Overall, 21 (8 %) patients were readmitted for infection (n = 8), headache (n = 5), hydrocephalus (n = 4), cardiovascular causes (n = 2), medication-related complications (n = 1), and cerebral ischemia (n = 1). Readmission was associated with longer intensive care unit (ICU) length of stay (LOS) (15.4 [13.4-19.3] vs. 12.2 [8.2-18.5] days, P = 0.02), hospital LOS (22.2 [17.4-23.0] vs. 16.8 [12.0-24.1] days, P = 0.01), and placement of an external ventricular drain (EVD, OR 3.9, 95 % CI 1.3-12.0, P = 0.01). Readmission was not associated with admission neurologic grade, NIH Stroke scale at 14 days, modified Rankin scale at 3 months, history of cardiovascular disease, or radiographic cerebral infarction (P > 0.1). CONCLUSIONS Demographics, severity of neurologic injury, radiographic cerebral infarction, and outcomes were not associated with readmission after SAH. Markers of a more complicated hospital course (ICU and hospital LOS, EVD placement) were associated with 30-day readmission. Most readmissions were for infections acquired after discharge. Readmission within 30 days is difficult to predict, and, since the most common reason was infection acquired after discharge, it may be difficult to prevent without an integrated health system and coordinated care.

Abstract
Introduction Takotsubo cardiomyopathy (TCM) is a life-threatening systemic consequence early after subarachnoid hemorrhage (SAH), but precise hemodynamics and related outcomes have not been studied. The purpose of this study was to investigate TCM-induced cardiac function by transpulmonary thermodilution and its impact on clinical outcome of SAH. Methods We retrospectively analyzed 46 consecutive postoperative SAH patients who developed TCM. Patients were divided into two groups of echocardiographic left ventricular ejection fraction (LVEF) <40% (TCM with left ventricular (LV) dysfunction) and LVEF ≥40% (TCM without LV dysfunction). Cardiac function index (CFI) and extravascular lung water index (ELWI) were monitored by transpulmonary thermodilution in parallel with serial measurements of echocardiographic parameters and blood biochemical markers. Results Transpulmonary thermodilution-derived CFI was significantly correlated with LVEF (r = 0.82, P < 0.0001). The CFI between days 0 and 7 was significantly lower in patients with LV dysfunction (LVEF <40%) than in patients with LVEF ≥40% (P < 0.05). CFI had a better ability than cardiac output to detect cardiac dysfunction (LVEF <40%) (area under the curve = 0.85 ± 0.02; P < 0.001). A CFI value <4.2 min−1 had a sensitivity of 82% and specificity of 84% for detecting LVEF <40%. CFI <4.2 min−1 was associated with delayed cerebral ischemia (DCI) (odds ratio (OR) = 2.14, 95% confidence interval (CI) = 1.33 to 2.86; P = 0.004) and poor 3-month functional outcome on a modified Rankin Scale of 4 to 6 (OR = 1.87, 95% CI = 1.06 to 3.29; P = 0.02). An extravascular lung water index (ELWI) >14 ml/kg after day 4 increased the risk of poor functional outcome at 3-month follow-up (OR = 2.10, 95% CI = 1.11 to 3.97; P = 0.04). Conclusions Prolonged cardiac dysfunction and pulmonary edema increased the risk of DCI and poor 3-month functional outcome in postoperative SAH patients with TCM. Serial measurements of CFI and ELWI by transpulmonary thermodilution may provide an easy bedside method of detecting early changes in cardiopulmonary function to direct proper post-SAH treatment.

Abstract
Critically ill neurologic patients are common in the hospital practice of neurology and are often in extreme states requiring accurate and specific information. Imaging, especially using advanced imaging techniques, can provide an important means of garnering this information. This article focuses on the clinical utilization of selective imaging methods that are commonly used in critically ill neurologic patients to render diagnoses, to monitor effects of treatment, or have contributed to a better understanding of pathophysiology in the intensive care unit.

Abstract
Middle cerebral artery (MCA) aneurysms are common entities, and those of the bifurcation are the most frequently encountered sublocation of MCA aneurysm. MCA bifurcation (MBIF) aneurysms commonly present with subarachnoid hemorrhage (SAH), are devastating, and are often lethal. At the present time, the treatment of ruptured MBIF aneurysms entails either endovascular or open microneurosurgical methods to permanently secure the aneurysm(s). The purpose of this report is to review the current available data regarding the relative superiority of endovascular versus open microneurosurgical clipping for the treatment of ruptured middle cerebral artery bifurcation aneurysms.

Abstract
Until recently, endovascular management of intracranial aneurysms has focused on mechanical and hemodynamic aspects: characterizing aneurysm morphology by angiogram, mechanical obstruction by detachable coils, and flow diversion with endovascular stents. Although now common practice, these interventions only ward off aneurysm rupture. The source of the problem, disease of the vessel wall itself, remains. New imaging technology and treatment modalities, however, are offering great promise to the field. In this review, we outline several new developments in the recent literature and pose potential adaptations toward cerebral aneurysms using them. The incidence, presentation, and contemporary endovascular treatment for aneurysms are first reviewed to lay the groundwork for new adaptations. Nanoparticles, including ultrasmall supraparagmenetic iron oxide particles (USPIOs), are next explored as a novel mechanism of predicting aneurysm wall instability and as an agent themselves for aneurysm occlusion. Cellular transplant grafts, bone marrow-derived stem cells (BM-MSCs), and endothelial progenitor cells (EPCs) are then investigated, with the role of cellular differentiation, chemokine secretion, and integration into the injured vascular wall receiving particular emphasis. Several promising translational papers are next discussed, with review of multiple studies that show benefit in aneurysm treatment and endovascular stenting using these agents as adjuncts. We next adapt these research findings into several potential applications we feel may be promising directions for the aspiring researcher. These new treatments may one day strengthen the arsenal of the endovascular neurosurgeon.

Abstract
Associations between the angiotensin II type 1 receptor (AGTR1) gene A1166C polymorphism and hypertension, aortic abdominal aneurysms (as a risk factor) as well as cardiovascular disorders (as a risk factor and an outcome predictor) have been demonstrated. We aimed to investigate the role of this polymorphism as risk factors and outcome predictors in primary intracerebral hemorrhage (PICH) and aneurysmal subarachnoid hemorrhage (aSAH). We have prospectively recruited 1078 Polish participants to the study: 261 PICH patients, 392 aSAH patients, and 425 unrelated control subjects. The A1166C AGTR1 gene polymorphism was studied using the tetra-primer ARMS-PCR method. Allele and genotype frequencies were compared with other ethnically different populations. The A1166C polymorphism was not associated with the risk of PICH or aSAH. Among the aSAH patients the AA genotype was associated with a good outcome, defined by a Glasgow Outcome Scale of 4 or 5 (p<0.02). The distribution of A1166C genotypes in our cohort did not differ from other white or other populations of European descent. In conclusion, we found an association between the A1166C AGTR1 polymorphism and outcome of aSAH patients, but not with the risk of PICH or aSAH.

Abstract
Delayed cerebral ischemia (DCI) is a feared and significant medical complication following aneurysmal subarachnoid hemorrhage (aSAH). It occurs in about 30% of patients surviving the initial hemorrhage, mostly between days 4 and 10 after aSAH. Clinical deterioration attributable to DCI is a diagnosis of exclusion and especially difficult to diagnose in patients who are comatose or sedated. The latter are typically patients with a high grade on the World Federation of Neurosurgical Societies scale (WFNS grade 4-5), who represent approximately 40-70% of the patient population with ruptured aneurysms. In this group of patients, the incidence of DCI is often underestimated and higher when compared to low WFNS grade patients. To overcome difficulties in diagnosing DCI, which is especially relevant in sedated and comatose patients, the article reports the most recent recommendation for definition of DCI and discusses their advantages and problematic issues in neurocritical care practice. Finally, appropriate neuromonitoring techniques and their clinical impact in high-grade SAH patients are summarized.

Abstract
Subarachnoid hemorrhage following intracranial aneurysmal rupture is a major cause of morbidity and mortality. Several factors may affect the probability of rupture, such as tobacco and alcohol use; size, shape, and location of the aneurysm; presence of intraluminal thrombus; and even the sex of the patient. However, few data correlate such findings with the timing of aneurysmal rupture. The authors report 2 cases of middle-age women with headache and MRI findings of incidental aneurysms. Magnetic resonance imaging showed evidence of surrounding parenchymal edema, and in one case there was a clear increase in edema during follow-up, suggesting a progressive inflammatory process that culminated with rupture. These findings raise the possibility that bleb formation and an enlargement of a cerebral aneurysm might be associated with an inflammatory reaction of the aneurysm wall resulting in perianeurysmal edema and subsequent aneurysmal rupture. There may be a temporal link between higher degree of edema and higher risk for rupture, including risk for immediate rupture.

Abstract
Background: A noncontrast computed tomography (CT) scan remains the initial radiological investigation of choice for a patient with suspected aneurysmal subarachnoid hemorrhage (aSAH). This initial scan may be used to derive key information about the underlying aneurysm which may aid in further management. The interpretation, however, is subject to the skill and experience of the interpreting individual. The authors here evaluate the interpretation of such CT scans by different individuals at different levels of training, and in two different specialties (Radiology and Neurosurgery). Methods: Initial nonontrast CT scan of 35 patients with aSAH was evaluated independently by four different observers. The observers selected for the study included two from Radiology and two from Neurosurgery at different levels of training; a resident currently in mid training and a resident who had recently graduated from training of each specialty. Measured variables included interpreter's suspicion of presence of subarachnoid blood, side of the subarachnoid hemorrhage, location of the aneurysm, the aneurysm's proximity to vessel bifurcation, number of aneurysm(s), contour of aneurysm(s), presence of intraventricular hemorrhage (IVH), intracerebral hemorrhage (ICH), infarction, hydrocephalus and midline shift. To determine the inter-observer variability (IOV), weighted kappa values were calculated. Results: There was moderate agreement on most of the CT scan findings among all observers. Substantial agreement was found amongst all observers for hydrocephalus, IVH, and ICH. Lowest agreement rates were seen in the location of aneurysm being supra or infra tentorial. There were, however, some noteworthy exceptions. There was substantial to almost perfect agreement between the radiology graduate and radiology resident on most CT findings. The lowest agreement was found between the neurosurgery graduate and the radiology graduate. Conclusion: Our study suggests that although agreements were seen in the interpretation of some of the radiological features of aSAH, there is still considerable IOV in the interpretation of most features among physicians belonging to different levels of training and different specialties. Whether these might affect management or outcome is unclear.

Abstract
Aim High blood pressure is observed frequently in patients with subarachnoid hemorrhage who present to the emergency department. Although extremely high blood pressure is known to predict poor outcomes in patients with spontaneous intracerebral hemorrhage, the relationship between high blood pressure and outcomes has been studied less frequently in patients with subarachnoid hemorrhage. Methods A retrospective study was carried out to evaluate whether high blood pressure observed in the emergency department was predictive of poor outcomes in patients with subarachnoid hemorrhage. Three-hundred and twelve subarachnoid hemorrhage patients who were admitted to our institution were quadrichotomized based on their initial systolic blood pressure: <140 mmHg (n = 60), 140-184 mmHg (n = 144), 185-219 mmHg (n = 64), and ≥220 mmHg (n = 44). Demographics including subarachnoid hemorrhage severity (World Federation of Neurosurgical Societies grade) and outcome variables evaluated with the modified Rankin scale 30 days after admission were compared among the four blood pressure groups. Furthermore, an effort was made to delineate a threshold value of systolic blood pressure predictive of outcomes by receiver operating characteristic curve analysis. Results The frequency of grade V subarachnoid hemorrhage in the ≥220 mmHg group (55%) was significantly higher than in the other three blood pressure groups. The frequency of patients scoring 5-6 on the modified Rankin scale in the ≥220 mmHg group (54%) was significantly higher than in the other three blood pressure groups. The cut-off systolic blood pressure value predicting poor outcomes (modified Rankin scale 5-6) determined by receiver operating characteristic curve analysis was 189 mmHg. Conclusions The higher proportion of grade V patients may be responsible for the worse outcomes in the group with systolic blood pressure ≥220 mmHg. Initial systolic blood pressure ≥220 mmHg may be a crude indicator of poor outcomes in patients with subarachnoid hemorrhage.

Abstract
OBJECTIVES Limited evidence supports the use of hemodynamic variables that correlate with delayed cerebral ischemia or pulmonary edema after aneurysmal subarachnoid hemorrhage. The aim of this study was to identify those hemodynamic variables that are associated with delayed cerebral ischemia and pulmonary edema after subarachnoid hemorrhage. DESIGN A multicenter prospective cohort study. SETTING Nine university hospitals in Japan. PATIENTS A total of 180 patients with aneurysmal subarachnoid hemorrhage. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Patients were prospectively monitored using a transpulmonary thermodilution system in the 14 days following subarachnoid hemorrhage. Delayed cerebral ischemia was developed in 35 patients (19.4%) and severe pulmonary edema was developed in 47 patients (26.1%). Using the Cox proportional hazards model, the mean global end-diastolic volume index (normal range, 680-800 mL/m) was the independent factor associated with the occurrence of delayed cerebral ischemia (hazard ratio, 0.74; 95% CI, 0.60-0.93; p = 0.008). Significant differences in global end-diastolic volume index were detected between the delayed cerebral ischemia and non-delayed cerebral ischemia groups (783 ± 25 mL/m vs 870 ± 14 mL/m; p = 0.007). The global end-diastolic volume index threshold that best correlated with delayed cerebral ischemia was less than 822 mL/m, as determined by receiver operating characteristic curves. Analysis of the Cox proportional hazards model indicated that the mean global end-diastolic volume index was the independent factor that associated with the occurrence of pulmonary edema (hazard ratio, 1.31; 95% CI, 1.02-1.71; p = 0.03). Furthermore, a significant positive correlation was identified between global end-diastolic volume index and extravascular lung water (r = 0.46; p < 0.001). The global end-diastolic volume index threshold that best correlated with severe pulmonary edema was greater than 921 mL/m. CONCLUSIONS Our findings suggest that global end-diastolic volume index impacts both delayed cerebral ischemia and pulmonary edema after subarachnoid hemorrhage. Maintaining global end-diastolic volume index slightly above normal levels has promise as a fluid management goal during the treatment of subarachnoid hemorrhage.

Abstract
Subarachnoid hemorrhage (SAH) is a devastating neurological disorder. Patients with aneurysmal SAH develop secondary complications that are important causes of morbidity and mortality. Aside from secondary neurological injuries, SAH has been associated with nonneurologic medical complications, such as neurocardiogenic injury, neurogenic pulmonary edema, hyperglycemia, and electrolyte imbalance, of which cardiac and pulmonary complications are most common. The related mechanisms include activation of the sympathetic nervous system, release of catecholamines and other hormones, and inflammatory responses. Extracerebral complications are directly related to the severity of SAH-induced brain injury and indicate the clinical outcome in patients. This review provides an overview of the extracerebral complications after SAH. We also aim to describe the manifestations, underlying mechanisms, and the effects of those extracerebral complications on outcome following SAH.

Abstract
Cerebral aneurysms pose a threat to patients because of their risk of rupture causing subarachnoid hemorrhage, and the goal of treatment is the exclusion of the aneurysm from the circulation to prevent bleeding (in the case of unruptured aneurysms) or rebleeding. This article analyzes the general technical factors associated with the endovascular treatment of cerebral aneurysms. It discusses issues with transarterial access; imaging of aneurysm size, morphology, and regional anatomy to determine the endovascular plan; the techniques for the major endovascular aneurysm devices; and periprocedural management issues to reduce potential treatment-related complications.

Abstract
Patients with nonaneurysmal perimesencephalic subarachnoid hemorrhage (NAPSAH) have no discernible source for the bleeding and generally are considered to have a benign condition. Correctly diagnosing these patients is essential because a missed aneurysm can have catastrophic consequences. Those presenting with NAPSAH have a low risk of complications and better outcome than patients presenting with aneurysmal subarachnoid hemorrhage; however, a limited body of literature suggests that not all of these patients are able to return to their premorbid functional status. Clinical screens of cognitive status, such as the mini-mental status examination, suggest good recovery of these patients, although these tests may lack sensitivity for identifying deficits in this patient population. More comprehensive neuropsychologic testing in some studies has identified deficits in a wide range of cognitive domains at long-term follow-up in patients with NAPSAH. Because these patients often do not lose consciousness (and thus do not have substantial transient global ischemia) and they do not undergo a procedure for aneurysm repair, the cognitive sequelae can be explained by the presence of blood in the subarachnoid space. NAPSAH presents an opportunity to understand the effects of subarachnoid blood in a clinical setting.

Abstract
Object
When patients present to the emergency department (ED) with acute headache concerning for subarachnoid hemorrhage (SAH) and a lumbar puncture (LP) shows blood in the CSF, it is difficult to distinguish the results of a traumatic LP from those of SAH. CT angiography (CTA) is often performed, but the long-term outcome for patients with a positive LP and normal neurovascular imaging remains uncertain. The primary objective of this study was to determine whether patients who presented to the ED with acute headache and had red blood cells (RBCs) in their CSF on LP but negative cerebrovascular imaging suffered subsequent SAH.
Methods
A case series study of consecutive adult ED patients who incurred charges for LP between 2001 and 2009 was performed from 2010 through 2011. Inclusion criteria were: headache, > 5 RBCs/mm3 in CSF, noncontrast head CT with no evidence of hemorrhage, and cerebrovascular CTA or MRA without aneurysm or vascular lesion within 2 weeks of the ED visit. Patients with less than 6 months of available follow-up were excluded. The primary outcomes were 1) subsequent nontraumatic SAH and 2) new vascular lesion. Secondary outcomes were complications related to SAH, or LP or angiography.
Results
Of 4641 ED patients billed for an LP, 181 patients (mean age 42 years) were included in this study. Over a median follow-up of 53 months, 0 (0%) of 181 patients (95% CI 0%–2.0%) had a subsequent SAH or new vascular lesion identified. Although not the primary outcome, there was 1 patient who was ultimately diagnosed with vasculitis. Eighteen (9.9%) of 181 patients (95% CI 6.0%–15.3%) had an LP-related complication and 0 (0%) of 181 patients (95% CI 0%–2.0%) had an angiography-related complication.
Conclusions
Patients who present to the ED with acute headache concerning for SAH and have a finding of bloody CSF on LP but negative findings on cerebrovascular imaging are at low risk for subsequent SAH and thus are likely to be safe for discharge. Replacement of the CT/LP with a CT/CTA diagnostic algorithm merits further investigation.

Suboptimal interventional conditions for the occlusion of ruptured intracranial aneurysms do not increase periprocedural complications and poor clinical outcomes. Acta Neurochir (Wien) 2014; 156:1267-72.

Abstract
BACKGROUND AND OBJECTIVE Occluding a ruptured intracranial aneurysm as early as possible may entail certain periprocedural conditions that compromise the outcome. The aim of the present study was to evaluate the effectiveness, safety, and clinical outcome of endovascular coiling procedures performed on an emergency basis under potentially suboptimal conditions, and to compare results with those from scheduled procedures under potentially optimal conditions. METHODS Interventions performed on 66 SAH patients were retrospectively analysed by classifying them into two groups: under emergency (within three hours from diagnosis or during non-standard working hours) or scheduled conditions. A binary logistic regression analysis was also performed to identify characteristics associated with poor outcomes. RESULTS No differences in effectiveness, periprocedural complications, or clinical outcomes were found between the two groups. Rebleeding was detected in 4.8 % of the emergency interventions and 2.2 % of the scheduled interventions. Multivariate analysis identified age and Hunt and Hess grade, but no conditions of treatment, as the factors associated to poor outcome. CONCLUSION Suboptimal interventional conditions for occluding ruptured intracranial aneurysms, such as performing procedures outside of standard working hours or within three hours of diagnosis, do not result in increased periprocedural complications and poor clinical outcomes compared with scheduled procedures under potentially optimal conditions. These results suggest the need for treatment to be provided as soon as possible.

Abstract
The earliest recorded application of therapeutic hypothermia in medicine spans about 5000 years; however, its use has become widespread since 2002, following the demonstration of both safety and efficacy of regimens requiring only a mild (32°C-35°C) degree of cooling after cardiac arrest. We review the mechanisms by which hypothermia confers neuroprotection as well as its physiological effects by body system and its associated risks. With regard to clinical applications, we present evidence on the role of hypothermia in traumatic brain injury, intracranial pressure elevation, stroke, subarachnoid hemorrhage, spinal cord injury, hepatic encephalopathy, and neonatal peripartum encephalopathy. Based on the current knowledge and areas undergoing or in need of further exploration, we feel that therapeutic hypothermia holds promise in the treatment of patients with various forms of neurologic injury; however, additional quality studies are needed before its true role is fully known.

Abstract
The aim of this paper was to report an unusual case of a 30-year-old woman admitted to the emergency department for a subarachnoid spinal haemorrhage. Clinical presentation was typical and the initial CT-scan did not show any intracranial lesions. Diagnosis was then confirmed by a full-spinal MRI that revealed a cervical radiculomedullary artery aneurysm. The diagnosis was also confirmed by an arteriography that showed a left C6 radiculomedullary artery aneurysm. Surgical management was performed and included a direct approach of the vascular lesion using an anterolateral cervicotomy and occlusion of the parent vessel. Histological examination confirmed the typical aspect of the aneurysm. The postoperative course was uneventful and the patient was discharged from hospital at day 15. This type of vascular lesion is very uncommon and requires a prompt diagnosis. Initial MRI can confirm the presence of a subarachnoid haemorrhage related to the aneurysm, which can be also visualized by an arteriography. Management of these vascular disorders requires a multidisciplinary specialized spine-team and is commonly performed using a direct surgical approach.

Abstract
The aims of this study were to develop a new coil, gellan sulfate core platinum coil (GSCC), that delivers tenascin-C (TNC) to an aneurysm (GSCC-TNC) and to evaluate the effects on intra-aneurysmal organization. We performed in vitro adsorption tests of TNC to gellan sulfate (GS). GSCC-TNC was produced by immersing GSCC in TNC solution under the following conditions (TNC concentration 10, 50, or 100 μg/mL; TNC immersion time 15, 30, or 60 min) by monitoring intra-aneurysmal organization in a rat blind-ended aneurysm model. In addition, 20 rats randomly underwent implantation of a platinum coil or the GSCC-TNC produced under optimum conditions into an aneurysm, whose organization effects were compared in a blind fashion at 2 weeks post-surgery. GS demonstrated a high affinity to TNC in a dose-dependent fashion (affinity constant = 1.79 × 10(10) (M(-1))). GSCC immersed in 10 μg/mL of TNC solution for 30 and 60 min induced similar and better organization of aneurysmal cavity compared with that for 15 min (the ratio of the organized areas in an aneurysmal cavity-15 min, 27.2 ± 11.8 %; 30 min, 75.6 ± 11.9 %; 60 min, 82.6 ± 19.7 %, respectively) with the preservation of the aneurysmal wall structure, while higher TNC concentrations caused the destruction of the aneurysmal wall. GSCC-TNC produced under 10 μg/mL of TNC solution for 30 min showed a significantly better organization of aneurysms compared with bare platinum coils in rats. A newly developed coil, GSCC-TNC, may be effective for improving intra-aneurysmal organization after coil embolization.

Abstract
BACKGROUND Anemia is a prevalent condition in critically ill patients and red blood cell transfusions are frequent. Although transfusions at low hemoglobin levels have been shown to be associated with equivalent or better outcomes than higher hemoglobin thresholds, clinical equipoise persists in patients with traumatic brain injury considering their susceptibility to secondary cerebral insults such as those from hypoxemia. METHODS Our objectives are to estimate the frequency of red blood cell transfusion in patients with traumatic brain injury and to evaluate transfusion thresholds, determinants and outcomes associated with transfusion strategies.We will conduct a systematic review of cohort studies and randomized controlled trials of patients with traumatic brain injury. We will search MEDLINE, Embase, BIOSIS and the Cochrane Library for eligible studies. Two independent reviewers will screen all identified references. Studies including adult patients with traumatic brain injury reporting data on red blood cell transfusions will be eligible. We will collect data on baseline demographics, trauma characteristics, hemoglobin thresholds, blood transfusions and clinical outcomes (mortality, length of stay, complications, and so on). Two independent reviewers will extract data using a standardized form. We will pool cumulative incidences using DerSimonian and Lair random-effect models after a Freeman-Tukey transformation to stabilize variances. We will pool risk ratios or mean differences with random-effect models and Mantel-Haenszel or inverse variance methods in order to evaluate the association between red blood cell transfusion and potential determinants or outcomes. Sensitivity and subgroup analysis according to timing of red blood cell transfusion, traumatic brain injury severity, year of conduction of the study, risk of bias, notably, are planned. DISCUSSION We expect to observe high heterogeneity in the proportion of transfused patients across studies and that the global proportion will be similar to the frequency observed in the general medical critically ill population. Our systematic review will allow us to better describe and understand current transfusion practices in patients with traumatic brain injury, a clinical population in which liberal transfusions are still advocated in the absence of evidence-based data.

Abstract
Aneurysmal subarachnoid hemorrhage (SAH) may be associated with acute cardiopulmonary complications, like neurogenic pulmonary edema (NPE) and Takotsubo-like cardiomyopathy (TCM). These dysfunctions seem to result from a neurogenically induced overstimulation of the sympathetic nervous system through the brain-heart connection and often complicate poor grade aneurysmal SAH. The optimal treatment modality and timing of intervention in this clinical setting have not been established yet. Early endovascular therapy seems to be the fitting treatment in this particular group of patients, in which surgical clipping is often contraindicated due to the added risk of craniotomy. Herein we describe the case of a woman admitted to the emergency department with aneurysmal SAH complicated by NPE-TCM, in which early endovascular coiling was successfully performed. Our case, characterized by a favorable outcome, further supports the evidence that early endovascular treatment should be preferred in this peculiar clinical scenario.

Abstract
Introduction Elevated brain potassium levels ([K+]) are associated with neuronal damage in experimental models. The role of brain extracellular [K+] in patients with poor-grade aneurysmal subarachnoid hemorrhage (aSAH) and its association with hemorrhage load, metabolic dysfunction and outcome has not been studied so far. Methods Cerebral microdialysis (CMD) samples from 28 poor grade aSAH patients were analyzed for CMD [K+] for 12 consecutive days after ictus, and time-matched to brain metabolic and hemodynamic parameters as well as corresponding plasma [K+]. Statistical analysis was performed using a generalized estimating equation with an autoregressive function to handle repeated observations of an individual patient. Results CMD [K+] did not correlate with plasma [K+] (Spearman’s ρ = 0.114, P = 0.109). Higher CMD [K+] was associated with the presence of intracerebral hematoma on admission head computed tomography, CMD lactate/pyruvate ratio >40 and CMD lactate >4 mmol/L (P < 0.05). In vitro retrodialysis data suggest that high CMD [K+] was of brain cellular origin. Higher CMD [K+] was significantly associated with poor 3-month outcome, even after adjusting for age and disease severity (P < 0.01). Conclusions The results of this pilot study suggest that brain extracellular [K+] may serve as a biomarker for brain tissue injury in poor-grade aSAH patients. Further studies are needed to elucidate the relevance of brain interstitial K+ levels in the pathophysiology of secondary brain injury after aSAH.

Abstract
BACKGROUND Specific morphological factors contribute to the hemodynamics of the anterior communicating artery (AComA). No study has examined the role of the A2 segment on AComA aneurysm presence and rupture. OBJECTIVE To examine the possibility that the ratio between A1 and A2 segments (A1-2 ratio) represents an independent risk factor for presence and rupture of AComA aneurysms (AComAAs). METHODS A retrospective review of an institutional aneurysm database was performed; patients with ruptured and unruptured AComAAs were identified. Two control groups were selected: group A (posterior circulation aneurysms) and group B (patients without intracranial aneurysms or other vascular malformations). Measurements of A1 and A2 diameters were obtained from digital subtraction angiography (64.1% of 3-D rotational digital subtraction angiography), and the A1-2 ratio calculated. RESULTS From January 2009 to April 2011, 156 patients were identified (52 AComAAs, 54 control group A, and 50 control group B). Mean age at the time of presentation was 56.09 years. Compared with both control groups, patients with AComAAs had greater A1 diameter (P < .01) and A1-2 ratio (P < .001) and smaller A2 diameter (P < .01). The A1-2 ratio correlated positively with the presence of AComAAs (P < .001). Ruptured AComAAs were smaller than unruptured ones (5.91 mm vs 9.25 mm, P = .02) and associated with a higher A1-2 Ratio (P = .02). The presence of a dominant A1 did not predict AComAA rupture (P = .15). The A1-2 ratio correlated positively with the presence of ruptured AComAAs (P = .04). CONCLUSION A1-2 ratio correlates positively with the presence and rupture of AComAAs and may facilitate treatment decision in cases of small, unruptured AComAAs.

Abstract
OBJECTIVE Nonconvulsive seizures (NCSz) are frequent following acute brain injury and have been implicated as a cause of secondary brain injury, but mechanisms that cause NCSz are controversial. Proinflammatory states are common after many brain injuries, and inflammation-mediated changes in blood-brain barrier permeability have been experimentally linked to seizures. METHODS In this prospective observational study of aneurysmal subarachnoid hemorrhage (SAH) patients, we explored the link between the inflammatory response following SAH and in-hospital NCSz studying clinical (systemic inflammatory response syndrome [SIRS]) and laboratory (tumor necrosis factor receptor 1 [TNF-R1], high-sensitivity C-reactive protein [hsCRP]) markers of inflammation. Logistic regression, Cox proportional hazards regression, and mediation analyses were performed to investigate temporal and causal relationships. RESULTS Among 479 SAH patients, 53 (11%) had in-hospital NCSz. Patients with in-hospital NCSz had a more pronounced SIRS response (odds ratio [OR]=1.9 per point increase in SIRS, 95% confidence interval [CI]=1.3-2.9), inflammatory surges were more likely immediately preceding NCSz onset, and the negative impact of SIRS on functional outcome at 3 months was mediated in part through in-hospital NCSz. In a subset with inflammatory serum biomarkers, we confirmed these findings linking higher serum TNF-R1 and hsCRP to in-hospital NCSz (OR=1.2 per 20-point hsCRP increase, 95% CI=1.1-1.4; OR=2.5 per 100-point TNF-R1 increase, 95% CI=2.1-2.9). The association of inflammatory biomarkers with poor outcome was mediated in part through NCSz. INTERPRETATION In-hospital NCSz were independently associated with a proinflammatory state following SAH as reflected in clinical symptoms and serum biomarkers of inflammation. Our findings suggest that inflammation following SAH is associated with poor outcome and that this effect is at least in part mediated through in-hospital NCSz.
