Background S100B has been described as a biologic marker of neuronal damage. The purpose of this study was to assess its prognostic value in patients with subarachnoid aneurysmal hemorrhage. Methods Seventy-four patients (32 men and 42 women; age, 48 +/- 11 yr) admitted within 48 h after subarachnoid hemorrhage onset and treated by surgical clipping or coiling within 2 days after admission were included. World Federation of Neurological Surgeons, Fisher, and Glasgow outcome scores at intensive care unit discharge and at 6 months were evaluated. Blood concentrations of S100B were determined at admission and daily up to day 8. Results The time course of S100B was increased in patients with high World Federation of Neurological Surgeons and Fisher scores. Patients who underwent surgical clipping had an S100B time course longer than that of those who underwent coiling. This difference remained true after stratification for World Federation of Neurological Surgeons and Fisher scores. The threshold of mean daily value of S100B predicting a poor outcome at 6 months was 0.4 microg/l (sensitivity = 0.50 [95% confidence interval (CI), 0.29-0.71], specificity = 0.87[corrected] [95% CI, 0.76-0.95]). In multivariate analysis, high World Federation of Neurological Surgeons score (odds ratio = 9.5 [95% CI, 3.1-29.4]), mean daily S100B value above 0.4 microg/l (odds ratio = 7.3 [95% CI, 2.3-23.6]), and age (odds ratio = 1.08 per year [95% CI, 1.01-1.15]) were independent predictors of a poor 6-month outcome (Glasgow outcome score 1-3). Conclusion Mean daily value of S100B assessed during the first 8 days is a prognostic tool complementary to initial clinical evaluation in subarachnoid hemorrhage patients.

Abstract BACKGROUND: The role and impact of systemic inflammatory response after aneurysmal subarachnoid hemorrhage remain to be elucidated. OBJECTIVE: To assess the time course and correlation of systemic inflammatory parameters with outcome and the occurrence of delayed ischemic neurological deficits (DINDs) after subarachnoid hemorrhage. METHODS: Besides the baseline characteristics, daily interleukin-6 (IL-6), procalcitonin, C-reactive protein levels, and leukocyte counts were prospectively measured until day 14 after subarachnoid hemorrhage. Occurrence of infectious complications and application of therapeutic hypothermia were assessed as confounding factors. The primary end point was outcome after 3 months, assessed by Glasgow Outcome Scale; the secondary end point was the occurrence of DINDs. RESULTS: During a 3-year period, a total of 138 patients were included. All inflammatory parameters measured were higher in patients with unfavorable outcome (Glasgow Outcome Scale score, 1-3). After adjustment for confounding factors, elevated IL-6 and leukocyte counts remained significant risk factors for unfavorable outcome. The odds ratio for log IL-6 was 4.07 (95% confidence interval, 1.18 to 14.03; P = .03) and for leukocyte counts was 1.24 (95% confidence interval, 1.06-1.46, P = .008). The analysis of the time course established that IL-6 was the only significantly elevated parameter in the early phase in patients with unfavorable outcome. Higher IL-6 levels in the early phase (days 3-7) were associated with the occurrence of DINDs. The adjusted odds ratio for log IL-6 was 4.03 (95% confidence interval, 1.21-13.40; P = .02). CONCLUSION: Higher IL-6 levels are associated with worse clinical outcome and the occurrence of DINDs. Because IL-6 levels were significantly elevated in the early phase, they might be a useful parameter to monitor.

Abstract Background This observational study was performed to show the impact of complications and interventions during neurocritical care on the outcome after aneurysmal subarachnoid hemorrhage (SAH). Methods We analyzed 203 cases treated for ruptured intracranial aneurysms, which were classified regarding clinical outcome after one year according to the modified Rankin Scale (mRS). We reviewed the data with reference to the occurrence of typical complications and interventions in neurocritical care units. Results Decompressive craniectomy (odds ratio 21.77 / 6.17 ; p < 0.0001 / p = 0.013), sepsis (odds ratio 14.67 / 6.08 ; p = 0.037 / 0.033) and hydrocephalus (odds ratio 3.71 / 6.46 ; p = 0.010 / 0.00095) were significant predictors for poor outcome and death after one year beside “World Federation of Neurosurgical Societies” (WFNS) grade (odds ratio 3.86 / 4.67 ; p < 0.0001 / p < 0.0001) and age (odds ratio 1.06 / 1.10 ; p = 0.0030 / p < 0.0001) in our multivariate analysis (binary logistic regression model). Conclusions In summary, decompressive craniectomy, sepsis and hydrocephalus significantly influence the outcome and occurrence of death after aneurysmal SAH.

Object. This study was undertaken to determine the outcomes in an unselected group of patients treated with semiurgent surgical clipping of aneurysms following subarachnoid hemorrhage (SAH). Methods. A clinical management outcome audit was conducted to determine outcomes in a group of 391 consecutive patients who were treated with a consistent policy of ultra-early surgery (all patients treated within 24 hours after SAH and 85% of them within 12 hours). All neurological grades were included, with 45% of patients having poor grades (World Federation of Neurosurgical Societies [WFNS] Grades IV and V). Patients were not selected on the basis of age; their ages ranged between 15 and 93 years and 19% were older than 70 years. The series included aneurysms located in both anterior and posterior circulations. Eighty-eight percent of all patients underwent surgery and only 2.5% of the series were selectively withdrawn (by family request) from the prescribed surgical treatment. In patients with good grades (WFNS Grades I–III) the 3-month postoperative outcomes were independence (good outcome) in 84% of cases, dependence (poor outcome) in 8% of cases, and death in 9%. In patients with poor grades the outcomes were independence in 40% of cases, dependence in 15% of cases, and death in 45%. There was a 12% rate of rebleeding with all cases of rebleeding occurring within the first 12 hours after SAH; however, outcomes of independence were achieved in 46% of cases in which rebleeding occurred (43% mortality rate). Rebleeding was more common in patients with poor grades (20% experienced rebleeding, whereas only 5% of patients with good grades experienced rebleeding). Conclusions. The major risk of rebleeding after SAH is present within the first 6 to 12 hours. This risk of ultra-early re-bleeding is highest for patients with poor grades. Securing ruptured aneurysms by surgery or coil placement on an emergency basis for all patients with SAH has a strong rational argument.

✓ Vasospasm following aneurysmal subarachnoid hemorrhage (SAH) is correlated with the thickness of blood within the basal cisterns on the initial computerized tomography (CT) scan. To identify additional risk factors for symptomatic vasospasm, the authors performed a prospective analysis of 75 consecutively admitted patients who were treated for aneurysmal SAH. Five patients who died before treatment or were comatose postoperatively were excluded from the study. Of the remaining 70 patients, demographic (age, gender, and race) and clinical (hypertension, diabetes, coronary artery disease, smoking, alcohol abuse, illicit drug use, sentinel headache, Fisher grade, Hunt and Hess grade, World Federation of Neurological Surgeons grade, and ruptured aneurysm location) parameters were evaluated using multivariate logistic regression to determine factors independently associated with cerebral vasospasm. All patients were treated with hypervolemic therapy and administration of nimodipine as prophylaxis for vasospasm. Cerebral vasospasm was suspected in cases that exhibited (by elevation of transcranial Doppler velocities) neurological deterioration 3 to 14 days after SAH with no other explanation and was confirmed either by clinical improvement in response to induced hypertension or by cerebral angiography. The mean age of the patients was 50 years. Sixty-three percent of the patients were women, 74% were white, 64% were cigarette smokers, and 46% were hypertensive. Ten percent of the patients suffered from alcohol abuse, 19% from sentinel bleed, and 49% had a Fisher Grade 3 SAH. Twenty-nine percent of the patients developed symptomatic vasospasm. Multivariate analysis demonstrated that cigarette smoking (p = 0.033; odds ratio 4.7, 95% confidence interval [CI] 2.4–8.9) and Fisher Grade 3, that is, thick subarachnoid clot (p = 0.008; odds ratio 5.1, 95% CI 2–13.1), were independent predictors of symptomatic vasospasm. The authors make the novel observation that cigarette smoking increases the risk of symptomatic vasospasm after aneurysmal SAH, independent of Fisher grade.

Objective: Early identification for the need of tracheostomy (TT) in aneurysmal subarachnoid hemorrhage (aSAH) patients remains one of the main challenges in clinical practice. Our study aimed to establish and validate a nomogram model for predicting postoperative TT in aSAH patients.Methods: Patients with aSAH receiving active treatment (interventional embolization or clipping) in our institution between June 2012 and December 2018 were retrospectively included. The effects of patients' baseline information, aneurysm features, and surgical factors on the occurrence of postoperative TT were investigated for establishing a nomogram in the training cohort with 393 patients. External validation for the nomogram was performed in the validation cohort with 242 patients.Results: After multivariate analysis, higher age, high neutrophil-to-lymphocyte ratio (NLR), high World Federation of Neurological Surgeons Scale (WFNS), and high Barrow Neurological Institute (BNI) grade were left in the final logistic regression model. The predictive power of the model was excellent in both training cohort and validation cohort [area under the curve (AUC): 0.924, 95% confidence interval [CI]: 0.893–0.948; AUC: 0.881, 95% CI: 0.833–0.919]. A nomogram consisting of these factors had a C-index of 0.924 (95% CI: 0.869–0.979) in the training cohort and was validated in the validation cohort (C-index: 0.881, 95% CI: 0.812–0.950). The calibration curves suggested good match between prediction and observation in both training and validation cohorts.Conclusion: Our study established and validated a nomogram model for predicting postoperative TT in aSAH patients.

Object Subarachnoid hemorrhage (SAH) results in the expression of inflammatory and extracellular matrix (ECM)–related genes and various G protein–coupled receptors. In the present study, the authors evaluated the time course and sequence of the transduction pathways, p38 mitogen-activated protein kinase (MAPK) and extracellular signal-regulated kinase–1 and 2 (ERK1/2), and associated transcription factor activation as well as gene regulation and associated protein levels. Methods Subarachnoid hemorrhage was induced in rats by injecting 250 μl of blood into the suprachiasmatic cistern, and gene regulation in the cerebral arteries was examined at various points in time following SAH by using quantitative polymerase chain reaction (PCR) and immunohistochemistry. Results Immunohistochemical findings demonstrated that SAH phosphorylates and activates p38 and ERK1/2 as well as the downstream transcription factors Elk-1 and activating transcription factor–2. The pattern of activation consists of a rapid phase within the first few hours and a late phase that occurs from 24 to 48 hours. Activation is followed by an increase in the transcription of the inflammatory and ECM-related genes (IL6, TNFα, IL1β, CXCL1, CXCL2, CCL20, MMP8, MMP9, MMP13, and iNOS), as demonstrated using real-time PCR. For MMP13 and iNOS, the changes in transcription were translated into functional proteins, as revealed on immunohistochemistry. Conclusions Activation of the p38 and ERK1/2 signaling pathways and their downstream transcription factors can explain the increase in the transcription of the genes studied. This increase and the subsequent augmentation in protein levels suggest that the inflammatory response may in part explain the remodeling that occurs in cerebral arteries following SAH.

Subarachnoid hemorrhage (SAH) represents a small portion of cerebrovascular disease but a disproportionally large percentage of the morbidity and mortality. The overall prognosis depends on the volume of the initial bleeding, rebleeding, and the degree of delayed cerebral ischemia. The presence of cardiac manifestations and neurogenic pulmonary edema at the initial presentation indicates a higher degree of severity and systemic complications. This review covers the pathophysiology, stabilization and assessment, diagnosis and treatment, and disposition and outcomes of SAH. Figures show common saccular aneurysm locations, a noncontrast head computed tomographic scan of an SAH, an angiogram and surgical clipping of a broad-based anterior communicating aneurysm, and a three-dimensional reconstruction angiogram of a complex anterior communicating aneurysm with additional imaging of endoscopic stent-assisted coiling of the same aneurysm. Tables list the natural history of unruptured aneurysms and the annual risk of rupture, common clinical features and syndromes related to aneurysm location, the World Federation of Neurologic Surgeons grading system, the Hunt and Hess grading systems, and the Fisher scale. This review contains 4 highly rendered figures, 5 tables, and 144 references. Key words: aneurysm rupture, cerebral aneurysm, cerebral vasospasm, Fisher scale, Glasgow Coma Scale assessment, Hunt and Hess grading criteria, subarachnoid hemorrhage, World Federation of Neurologic Surgeons grading scale  Key Advances CT angiography is an emerging technology that has the diagnostic advantage of being non-invasive.  The diagnostic accuracy of CTA varies widely and when compared to the standard digital subtraction angiography (DSA) the sensitivity and specificity range from 77% to 100% and 87%-100% respectively. The 2012 AHA guidelines and the 2011 Neurocritical care society (NCS) consensus guidelines recommend that from the time of symptom onset to securing of the aneurysm, the blood pressure be controlled with a titratable agent with a goal systolic blood pressure of less than 160mmHg or a MAP of less than 110mmHg. Cardiac abnormalities are common following acute SAH.  Subendocardial ischemia may result from autonomic stimulation from the brain and circulating catecholamine surge, resulting in an abnormal ECG in 50% to 100% of patients with SAH in the acute phase depending on severity. The International Subarachnoid Aneurysm Trial ISAT was a landmark study that looked at aSAH repair comparing surgical clipping with endoscopic coiling and demonstrated a mortality benefit with coiling in the right patient population.

Abstract Object The timing of definitive management of ruptured intracranial aneurysms has been the subject of considerable debate, although the benefits of early surgery (until 72 hours postictus) are widely accepted. The aim of the present study is to evaluate the potential benefit of ultra-early surgery (until 24 hours) when compared with early surgery, in those patients who were treated by surgical clipping at the Neurosurgery Department of the Coimbra Hospital and University Centre. Methods A 17-year database of consecutive ruptured and surgically treated intracranial aneurysms was analyzed. Outcome was measured by the Glasgow Outcome Scale (GOS). Baseline characteristics were analyzed by the Fisher exact test, the chi-squared and Mann-Whitney tests. Logistic regression was used to assess the impact of good grade according to the World Federation of Neurological Surgeons (WFNS) scale and ultra-early surgery in a good GOS outcome. Results 343 patients who were submitted to surgical clipping in the first 72 hours post-ictus were included, 165 of whom have undergone ultra-early surgery. Demographics and preoperative characteristics of ultra-early and early surgery patients were similar. Good-grade patients according to the WFNS scale submitted to ultra-early surgery demonstrated an improved GOS at discharge and at 6 months. Poor-grade patients according to the WFNS scale submitted to ultra-early surgery demonstrated an improved GOS at discharge. Conclusions Ultra-early surgery for aneurysmal subarachnoid hemorrhage patients improves outcome mainly on good-grade patients. Efforts should be made on the logistics of emergency departments to consider achieving treatment on this timeframe as a standard of care.

OBJECTIVEThe objective of this study was to measure the concentration of nimodipine in CSF and plasma after intraventricular injection of a sustained-release formulation of nimodipine (EG-1962) in patients with aneurysmal subarachnoid hemorrhage (SAH).METHODSPatients with SAH repaired by clip placement or coil embolization were randomized to EG-1962 or oral nimodipine. Patients were classified as grade 2–4 on the World Federation of Neurosurgical Societies grading scale for SAH and had an external ventricular drain inserted as part of their standard of care. Cohorts of 12 patients received 100–1200 mg of EG-1962 as a single intraventricular injection (9 per cohort) or they remained on oral nimodipine (3 per cohort). Plasma and CSF were collected from each patient for measurement of nimodipine concentrations and calculation of maximum plasma and CSF concentration, area under the concentration-time curve from day 0 to 14, and steady-state concentration.RESULTSFifty-four patients in North America were randomized to EG-1962 and 18 to oral nimodipine. Plasma concentrations increased with escalating doses of EG-1962, remained stable for 14 to 21 days, and were detectable at day 30. Plasma concentrations in the oral nimodipine group were more variable than for EG-1962 and were approximately equal to those occurring at the EG-1962 800-mg dose. CSF concentrations of nimodipine in the EG-1962 groups were 2–3 orders of magnitude higher than in the oral nimodipine group, in which nimodipine was only detected at low concentrations in 10% (21/213) of samples. In the EG-1962 groups, CSF nimodipine concentrations were 1000 times higher than plasma concentrations.CONCLUSIONSPlasma concentrations of nimodipine similar to those achieved with oral nimodipine and lasting for 21 days could be achieved after a single intraventricular injection of EG-1962. The CSF concentrations from EG-1962, however, were at least 2 orders of magnitude higher than those with oral nimodipine. These results supported a phase 3 study that demonstrated a favorable safety profile for EG-1962 but yielded inconclusive efficacy results due to notable differences in clinical outcome based on baseline disease severity.Clinical trial registration no.: NCT01893190 (ClinicalTrials.gov).
