Tranexamic acid for patients with aneurysmal subarachnoid hemorrhage: a systematic review and meta-analysis of 2991 patients. Int J Neurosci 2024; 134:763-776. [PMID: 36463556 DOI: 10.1080/00207454.2022.2148957] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2022] [Revised: 06/24/2022] [Accepted: 06/30/2022] [Indexed: 12/05/2022]
Abstract
OBJECTIVE We aimed to synthesize evidence from published clinical trials on the efficacy and safety of tranexamic acid (TXA) administration in patients with aneurysmal subarachnoid hemorrhage (aSAH). METHODS We followed the standard methods of the Cochrane Handbook of Systematic Reviews for interventions and the PRISMA statement guidelines 2020 when conducting and reporting this study. A computer literature search of PubMed, Scopus, Web of Science, and Cochrane Central Register of Controlled Trials was conducted from inception until 1 January 2022. We selected observational studies and clinical trials comparing TXA versus no TXA in aSAH patients. Data of all outcomes were pooled as the risk ratio (RR) with the corresponding 95% confidence intervals in the meta-analysis models. RESULTS Thirteen studies with a total of 2991 patients were included in the analysis. TXA could significantly cut the risk of rebleeding (RR 0.56, 95% CI 0.44 to 0.72) and mortality from rebleeding (RR 0.60, 95% CI 0.39 to 0.92, p = 0.02). However, TXA did not significantly improve the overall mortality, neurological outcome, delayed cerebral ischemia, or hydrocephalus (all p > 0.05). In terms of safety, no significant adverse events were reported. No statistical heterogeneity or publication bias was found in all outcomes. CONCLUSION In patients with aSAH, TXA significantly reduces the incidence of rebleeding and mortality from rebleeding. However, current evidence does not support any benefits in overall mortality, neurological outcome, delayed cerebral ischemia, or hydrocephalus.

Abstract
INTRODUCTION The ULTRA-trial investigated effectiveness of ultra-early administration of tranexamic acid (TXA) in subarachnoid hemorrhage (SAH) and showed that TXA reduces the risk of rebleeding without concurrent improvement in clinical outcome. Previous trials in bleeding conditions, distinct from SAH, have shown that time to start of antifibrinolytic treatment influences outcome. This post-hoc analysis of the ULTRA-trial investigates whether the interval between hemorrhage and start of TXA impacts the effect of TXA on rebleeding and functional outcome following aneurysmal SAH. PATIENTS AND METHODS A post-hoc comparative analysis was conducted between aneurysmal SAH patients of the ULTRA-trial, receiving TXA and usual care to those receiving usual care only. We assessed confounders, hazard ratio (HR) of rebleeding and odds ratio (OR) of good outcome (modified Rankin Scale 0-3) at 6 months, and investigated the impact of time between hemorrhage and start of TXA on the treatment effect, stratified into time categories (0-3, 3-6 and >6 h). RESULTS Sixty-four of 394 patients (16.2%) in the TXA group experienced a rebleeding, compared to 83 of 413 patients (19.9%) with usual care only (HR 0.86, 95% confidence interval (CI): 0.62-1.19). Time to start of TXA modifies the effect of TXA on rebleeding rate (p < 0.001), with a clinically non-relevant reduction observed only when TXA was initiated after 6 h (absolute rate reduction 1.4%). Tranexamic acid treatment showed no effect on good outcome (OR 0.96, 95% CI: 0.72-1.27) with no evidence of effect modification on the time to start of TXA (p = 0.53). DISCUSSION AND CONCLUSIONS This study suggests that the effect of TXA on rebleeding is modified by time to treatment, providing a protective, albeit clinically non-relevant, effect only when started after 6 h. No difference in functional outcome was seen. Routine TXA treatment in the aneurysmal SAH population, even within a specified time frame, is not recommended to improve functional outcome.

Protocol for a randomized, placebo-controlled, double-blind phase IIa study of the safety, tolerability, and symptomatic efficacy of the ROCK-inhibitor Fasudil in patients with Parkinson's disease (ROCK-PD). Front Aging Neurosci 2024; 16:1308577. [PMID: 38419648 PMCID: PMC10899319 DOI: 10.3389/fnagi.2024.1308577] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Accepted: 02/01/2024] [Indexed: 03/02/2024] Open
Abstract
Background The Rho-kinase (ROCK) inhibitor Fasudil has shown symptomatic and disease-modifying effects in Parkinson's disease (PD) models in vitro and in vivo. In Japan, Fasudil has been approved for the treatment of subarachnoid haemorrhage since 1995 and shows a favourable safety profile. Objectives/design To investigate the safety, tolerability, and symptomatic efficacy of ROCK-inhibitor Fasudil in comparison to placebo in a randomized, national, multicenter, double-blind phase IIa study in patients with PD. Methods/analysis We plan to include 75 patients with at least 'probable' PD (MDS criteria), Hoehn and Yahr stages 1-3, and age 30-80 years in 13 German study sites. Patients must be non-fluctuating and their response to PD medication must have been stable for 6 weeks. Patients will be randomly allocated to treatment with the oral investigational medicinal product (IMP) containing either Fasudil in two dosages, or placebo, for a total of 22 days. As primary analysis, non-inferiority of low/high dose of Fasudil on the combined endpoint consisting of occurrence of intolerance and/or treatment-related serious adverse events (SAEs) over 22 days will be assessed in a sequential order, starting with the lower dose. Secondary endpoints will include tolerability alone over 22 days and occurrence of treatment-related SAEs (SARs) over 22 and 50 days and will be compared on group level. Additional secondary endpoints include efficacy on motor and non-motor symptoms, measured on established scales, and will be assessed at several timepoints. Biomaterial will be collected to determine pharmacokinetics of Fasudil and its active metabolite, and to evaluate biomarkers of neurodegeneration. Ethics/registration/discussion After positive evaluation by the competent authority and the ethics committee, patient recruitment started in the 3rd quarter of 2023. ROCK-PD is registered with Eudra-CT (2021-003879-34) and clinicaltrials.gov (NCT05931575). Results of this trial can pave way for conducting extended-duration studies assessing both symptomatic efficacy and disease-modifying properties of Fasudil.

Front Neurol 2024; 14:1280047. [PMID: 38259653 PMCID: PMC10800534 DOI: 10.3389/fneur.2023.1280047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Accepted: 12/15/2023] [Indexed: 01/24/2024] Open
Abstract
Background Aneurysmal subarachnoid hemorrhage (aSAH) is a devastating stroke subtype with high morbidity and mortality. Although several studies have developed a prediction model in aSAH to predict individual outcomes, few have addressed short-term mortality in patients requiring mechanical ventilation. The study aimed to construct a user-friendly nomogram to provide a simple, precise, and personalized prediction of 30-day mortality in patients with aSAH requiring mechanical ventilation. Methods We conducted a post-hoc analysis based on a retrospective study in a French university hospital intensive care unit (ICU). All patients with aSAH requiring mechanical ventilation from January 2010 to December 2015 were included. Demographic and clinical variables were collected to develop a nomogram for predicting 30-day mortality. The least absolute shrinkage and selection operator (LASSO) regression method was performed to identify predictors, and multivariate logistic regression was used to establish a nomogram. The discriminative ability, calibration, and clinical practicability of the nomogram to predict short-term mortality were tested using the area under the curve (AUC), calibration plot, and decision curve analysis (DCA). Results Admission GCS, SAPS II, rebleeding, early brain injury (EBI), and external ventricular drain (EVD) were significantly associated with 30-day mortality in patients with aSAH requiring mechanical ventilation. Model A incorporated four clinical factors available in the early stages of the aSAH: GCS, SAPS II, rebleeding, and EBI. Then, the prediction model B with the five predictors was developed and presented in a nomogram. The predictive nomogram yielded an AUC of 0.795 [95% CI, 0.731-0.858], and in the internal validation with bootstrapping, the AUC was 0.780. The predictive model was well-calibrated, and decision curve analysis further confirmed the clinical usefulness of the nomogram. Conclusion We have developed two models and constructed a nomogram that included five clinical characteristics to predict 30-day mortality in patients with aSAH requiring mechanical ventilation, which may aid clinical decision-making.

Abstract
INTRODUCTION There are two treatment modalities for aneurysmal subarachnoid hemorrhage: endovascular treatment (EVT) and neurosurgical clipping. Results of economic evaluations are needed to gain insight into the relationship between clinical effectiveness and costs of these treatment modalities. This important information can inform both clinical decision-making processes and policymakers in facilitating Value-Based Healthcare. EVIDENCE ACQUISITION Databases (PubMed, Embase, Cochrane Library, the Centre for Reviews and Dissemination, EBSCO, and Web of Science) were searched for studies published until October 2020 that had performed economic evaluations in aneurysmal subarachnoid hemorrhage patients by comparing EVT with neurosurgical clipping. The quality of reporting and methodology of these evaluations was assessed using the associated instruments (i.e. CHEERS statement and CHEC-list, respectively). EVIDENCE SYNTHESIS A total of 6 studies met the inclusion criteria. All included studies reported both effects and costs, however five did not relate effects to costs. Only one study related effects directly to costs, thus conducted a full economic evaluation. The reporting quality scored 81% and the methodological quality scored 30%. CONCLUSIONS The quality of published cost-effectiveness studies on the treatment of aneurysmal subarachnoid hemorrhage is poor. Six studies reported both outcomes and costs, however only one study performed a full economic evaluation comparing EVT to neurosurgical clipping. Although the reporting quality was sufficient, the methodological quality was poor. Further research that relates health-related quality of life measures to costs of EVT and neurosurgical clipping is required - specifically focusing on both reporting and methodological quality. Different subgroup analyses and modeling could also enhance the findings.

Duration between aneurysm rupture and treatment and its association with outcome in aneurysmal subarachnoid haemorrhage. Sci Rep 2023; 13:1527. [PMID: 36707604 PMCID: PMC9883503 DOI: 10.1038/s41598-022-27177-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Accepted: 12/27/2022] [Indexed: 01/29/2023] Open
Abstract
Timely treatment of aneurysmal subarachnoid haemorrhage (aSAH) is key to prevent further rupture and poor outcome. We evaluated complications and outcome adjusting for time from haemorrhage to treatment. Retrospective analysis of aSAH patients admitted between 2006 and 2020. Data was collected using standardized case report forms. We compared risk factors using multivariable logistic regression. We included 853 patients, 698 (81.8%) were treated within 24 h. Patients with higher Hunt and Hess grades were admitted and treated significantly faster than those with lower grades (overall p-value < 0.001). Fifteen patients (1.8%) rebled before intervention. In the multivariable logistic analysis adjusting for timing, Barrow Neurological Institute score and intracerebral haemorrhage were significantly associated with rebleeding (overall p-value 0.006; OR 3.12, 95%CI 1.09-8.92, p = 0.03, respectively) but timing was not. Treatment > 24 h was associated with higher mortality and cerebral infarction in only the subgroup of lower grades aSAH (OR 3.13, 1.02-9.58 95%CI, p-value = 0.05; OR 7.69, 2.44-25.00, p-value < 0.001, respectively). Therefore treatment > 24 h after rupture is associated with higher mortality and cerebral infarction rates in lower grades aSAH. Delay in treatment primarily affects lower grade aSAH patients. Patients with lower grade aSAH ought to be treated with the same urgency as higher-grade aSAH.

Abstract
ABSTRACT BACKGROUND : Prompt aneurysm repair is essential to prevent rebleeding after aneurysmal subarachnoid hemorrhage. To date, most studies on this topic have focused on 1 set of predictors (eg, hospital or patient characteristics) and on 1 outcome (either time to aneurysm repair or mortality). The purpose of this study was to test a model that includes hospital and patient characteristics as predictors of time to aneurysm repair and mortality, controlling for disease severity and comorbidity, and considering time to aneurysm repair as a potential influence in these relationships. METHODS : A sample of aneurysmal subarachnoid hemorrhage patients with a principal procedure of clipping or coiling was selected (n = 387) from a statewide administrative database for cross-sectional retrospective analysis. The primary study outcome was in-hospital mortality. Independent variables were level of stroke center, age, race, sex, and type of aneurysm repair. Hierarchical logistic regression was used to estimate the probability of in-hospital death. RESULTS : Patients who underwent a coiling procedure were more likely to be treated within the first 24 hours of admission compared with those undergoing clipping (odds ratio, 0.54; 95% CI, 0.35-0.84; P = .01). Patients treated at a certified comprehensive stroke center (CSC) had a 72% reduction in odds of death compared with those treated at primary stroke centers (odds ratio, 0.28; 95% CI, 0.10-0.77; P = .01), after controlling for disease severity and comorbid conditions. Time to aneurysm repair was not significantly associated with mortality and did not influence the relationship between hospital and patient characteristics and mortality. CONCLUSION : Our results indicate that treatment at a CSC was associated with a lower risk of in-hospital mortality. Time to aneurysm repair did not influence mortality and did not explain the mortality benefit observed in CSCs. Research is needed to explore interdisciplinary hospital factors including nursing and nurse-sensitive interventions that may explain the relationship between CSCs and mortality outcomes.

Abstract
Background Delayed cerebral ischemia (DCI) is a primary cause of poor prognosis after aneurysmal subarachnoid hemorrhage (aSAH) and needs close medical attention in clinical practice. Homocysteine (Hcy) has been implicated in cerebrovascular diseases. This study aimed to investigate whether serum Hcy could help to predict the occurrence of DCI in aSAH patients, and compare its diagnostic value with traditional methods. Methods We enrolled 241 aSAH patients in this study. Serum Hcy levels were collected from each patient. The baseline information was reviewed and analyzed. The binary logistic regression was used to explore the relation of serum Hcy levels with occurrence of DCI, and diagnostic performance of serum Hcy for predicting DCI was evaluated using a receiver operating characteristic (ROC) curve. Results The admission serum Hcy levels were found significantly higher in aSAH patients with DCI than those without (P < 0.001). The serum Hcy levels were positively correlated with the World Federation of Neurosurgical Societies (WFNS) scores, modified Fisher scores as well as Hunt and Hess scores at admission. Multivariate analysis revealed that occurrence of DCI was associated with serum Hcy levels (Odds Ratio [OR] = 1.257; 95% Confidence Interval [CI], 1.133–1.396, P < 0.001), modified Fisher scores (OR = 1.871; 95%CI, 1.111–3.150, P = 0.018) and Hunt and Hess scores (OR = 2.581; 95%CI, 1.222–5.452, P = 0.013) after adjusting for the significant variables in univariate analysis. Meanwhile, serum Hcy levels achieved good performance for DCI prediction (area under the curve [AUC], 0.781; 95%CI, 0.723–0.831, P < 0.001). Conclusion Serum homocysteine might have the potential to be a useful and cost-effective biomarker for predicting the occurrence of DCI in aSAH patients.

Abstract
Introduction: Recent reports revealed that higher serum glucose-potassium ratio (GPR) levels at admission were significantly associated with poor outcomes at 3 months following aneurysmal subarachnoid hemorrhage (aSAH). This study aimed to investigate the association between GPR and the risk of rebleeding following aSAH. Methods: This single-center retrospective study of patients with aSAH was conducted in our hospital between January 2008 and December 2020. Patients meeting the inclusion criteria were divided into the rebleed group and the non-rebleed group. Univariate and multivariate analyses were implemented to assess the association between risk factors of rebleeding and outcomes. Results: A total of 1,367 patients experiencing aSAH, 744 patients who met the entry criteria in the study [mean age (54.89 ± 11.30) years; 60.50% female patients], of whom 45 (6.05%) developed rebleeding. The patients in the rebleed group had significantly higher GPR levels than those of patients without rebleeding [2.13 (1.56-3.20) vs. 1.49 (1.23-1.87); p < 0.001]. Multivariable analysis revealed that higher mFisher grade and GPR were associated with rebleeding [mFisher grade, odds ratios (OR) 0.361, 95% CI 0.166-0.783, p = 0.01; GPR, OR 0.254, 95% CI 0.13-0.495, p < 0.001]. The receiver operating characteristics (ROCs) analysis described that the suitable cut-off value for GPR as a predictor for rebleeding in patients with aSAH was determined as 2.09 (the area under the curve [AUC] was 0.729, 95% CI 0.696-0.761, p < 0.0001; the sensitivity was 53.33%, and the specificity was 83.98%). Pearson correlation analysis showed a significant positive correlation between GPR and mFisher grade, between GPR and Hunt-Hess grade (mFisher grade r = 0.4271, OR 0.1824, 95% CI 0.3665-0.4842, p < 0.001; Hunt-Hess grade r = 0.4248, OR 0.1836, 95% CI 0.3697-0.4854, p < 0.001). The patients in the poor outcome had significantly higher GPR levels than those of patients in the good outcome [1.87 (1.53-2.42) vs. 1.45 (1.20-1.80); p < 0.001]. Multivariable analysis demonstrated that GPR was an independent predictor for poor prognosis. The AUC of GPR was 0.709 (95% CI 0.675-0.741; p < 0.0001) (sensitivity = 77.70%; specificity = 55.54%) for poor prognosis. Conclusion: Higher preoperative serum GPR level was associated with Hunt-Hess grade, mFisher grade, rebleeding, and unfunctional outcome, and that they predicted preoperative rebleeding and the 90-days outcome of non-diabetic patients with aSAH, who had potentially relevant clinical implications in patients with aSAH.

Abstract
PURPOSE To evaluate the distribution and impact of ABO blood group on the baseline characteristics and clinical outcomes of patients presenting with aneurysmal subarachnoid haemorrhage (aSAH). METHODS Retrospective, single-centre study of patients admitted to a neurosurgical department in the UK, with a diagnosis of spontaneous subarachnoid haemorrhage between May 2014 and January 2020. Patients were categorised by ABO blood type and by Rhesus status. Clinical outcomes such as initial bleeding, rebleeding, delayed cerebral ischaemia (DIND) and venous thromboembolism were analysed in relation to the size of their association with ABO blood type. Hospital mortality rate, Glasgow Outcome Score (GOS) - at discharge and 3 months post-ictus, requirement for ventriculoperitoneal shunt insertion, discharge destination and inpatient length of stay were also considered. RESULTS Four-hundred twelve adult patients admitted with aSAH were included in our analysis. The distribution of ABO group or Rhesus status in our cohort did not differ significantly from the general population in the UK. Blood group A patients had a significantly increased risk of developing DIND, compared with non-blood group A patients (OR, 1.88 [95% CI: 1.10-3.21]). CONCLUSIONS ABO blood type appears to influence aSAH sequelae. Blood group A patients are at highest risk of DIND following aSAH.

Abstract
Sex differences in cerebral aneurysm occurrence and characteristics have been well described. Although sex differences in outcomes following ischemic stroke have been identified, the effect of sex on outcomes following hemorrhagic stroke, and in particular, aneurysm treatment has been less studied. We describe the current state of knowledge regarding the impact of sex on treatment and outcomes of cerebral aneurysms. Although prior studies suggest that aneurysm prevalence and progression may be related to sex, we did not find clear evidence that outcomes following subarachnoid hemorrhage vary based on sex. Last, we identify areas for future research that could enhance understanding of the role sex plays in this context.

Abstract
BACKGROUND Subarachnoid haemorrhage has an incidence of up to nine per 100,000 person-years. It carries a mortality of 30% to 45% and leaves 20% dependent in activities of daily living. The major causes of death or disability after the haemorrhage are delayed cerebral ischaemia and rebleeding. Interventions aimed at lowering blood pressure may reduce the risk of rebleeding, while the induction of hypertension may reduce the risk of delayed cerebral ischaemia. Despite the fact that medical alteration of blood pressure has been clinical practice for more than three decades, no previous systematic reviews have assessed the beneficial and harmful effects of altering blood pressure (induced hypertension or lowered blood pressure) in people with acute subarachnoid haemorrhage. OBJECTIVES To assess the beneficial and harmful effects of altering arterial blood pressure (induced hypertension or lowered blood pressure) in people with acute subarachnoid haemorrhage. SEARCH METHODS We searched the following from inception to 8 September 2020 (Chinese databases to 27 January 2019): Cochrane Stroke Group Trials register; CENTRAL; MEDLINE; Embase; five other databases, and five trial registries. We screened reference lists of review articles and relevant randomised clinical trials. SELECTION CRITERIA Randomised clinical trials assessing the effects of inducing hypertension or lowering blood pressure in people with acute subarachnoid haemorrhage. We included trials irrespective of publication type, status, date, and language. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data. We assessed the risk of bias of all included trials to control for the risk of systematic errors. We performed trial sequential analysis to control for the risks of random errors. We also applied GRADE. Our primary outcomes were death from all causes and death or dependency. Our secondary outcomes were serious adverse events, quality of life, rebleeding, delayed cerebral ischaemia, and hydrocephalus. We assessed all outcomes closest to three months' follow-up (primary point of interest) and maximum follow-up. MAIN RESULTS We included three trials: two trials randomising 61 participants to induced hypertension versus no intervention, and one trial randomising 224 participants to lowered blood pressure versus placebo. All trials were at high risk of bias. The certainty of the evidence was very low for all outcomes. Induced hypertension versus control Two trials randomised participants to induced hypertension versus no intervention. Meta-analysis showed no evidence of a difference between induced hypertension versus no intervention on death from all causes (risk ratio (RR) 1.60, 95% confidence interval (CI) 0.57 to 4.42; P = 0.38; I2 = 0%; 2 trials, 61 participants; very low-certainty evidence). Trial sequential analyses showed that we had insufficient information to confirm or reject our predefined relative risk reduction of 20% or more. Meta-analysis showed no evidence of a difference between induced hypertension versus no intervention on death or dependency (RR 1.29, 95% CI 0.78 to 2.13; P = 0.33; I2 = 0%; 2 trials, 61 participants; very low-certainty evidence). Trial sequential analyses showed that we had insufficient information to confirm or reject our predefined relative risk reduction of 20% or more. Meta-analysis showed no evidence of a difference between induced hypertension and control on serious adverse events (RR 2.24, 95% CI 1.01 to 4.99; P = 0.05; I2 = 0%; 2 trials, 61 participants; very low-certainty evidence). Trial sequential analysis showed that we had insufficient information to confirm or reject our predefined relative risk reduction of 20% or more. One trial (41 participants) reported quality of life using the Stroke Specific Quality of Life Scale. The induced hypertension group had a median of 47 points (interquartile range 35 to 55) and the no-intervention group had a median of 49 points (interquartile range 35 to 55). The certainty of evidence was very low. One trial (41 participants) reported rebleeding. Fisher's exact test (P = 1.0) showed no evidence of a difference between induced hypertension and no intervention on rebleeding. The certainty of evidence was very low. Trial sequential analysis showed that we had insufficient information to confirm or reject our predefined relative risk reduction of 20% or more. One trial (20 participants) reported delayed cerebral ischaemia. Fisher's exact test (P = 1.0) showed no evidence of a difference between induced hypertension and no intervention on delayed cerebral ischaemia. The certainty of the evidence was very low. Trial sequential analysis showed that we had insufficient information to confirm or reject our predefined relative risk reduction of 20% or more. None of the trials randomising participants to induced hypertension versus no intervention reported on hydrocephalus. No subgroup analyses could be conducted for trials randomising participants to induced hypertension versus no intervention. Lowered blood pressure versus control One trial randomised 224 participants to lowered blood pressure versus placebo. The trial only reported on death from all causes. Fisher's exact test (P = 0.058) showed no evidence of a difference between lowered blood pressure versus placebo on death from all causes. The certainty of evidence was very low. AUTHORS' CONCLUSIONS Based on the current evidence, there is a lack of information needed to confirm or reject minimally important intervention effects on patient-important outcomes for both induced hypertension and lowered blood pressure. There is an urgent need for trials assessing the effects of altering blood pressure in people with acute subarachnoid haemorrhage. Such trials should use the SPIRIT statement for their design and the CONSORT statement for their reporting. Moreover, such trials should use methods allowing for blinded altering of blood pressure and report on patient-important outcomes such as mortality, rebleeding, delayed cerebral ischaemia, quality of life, hydrocephalus, and serious adverse events.

Abstract
Objective Rebleeding is recognized as the main cause of mortality after intracranial aneurysm rupture. Though timely intervention can prevent poor prognosis, there is no agreement on the surgical priority and choosing medical treatment for a short period after rupture. The aim of this study was to investigate the risk factors related to the rebleeding after admission and establish predicting models for better clinical decision-making. Methods The patients with ruptured intracranial aneurysms (RIAs) between January 2018 and September 2020 were reviewed. All patients fell to the primary and the validation cohort by January 2020. The hemodynamic parameters were determined through the computational fluid dynamics simulation. Cox regression analysis was conducted to identify the risk factors of rebleeding. Based on the independent risk factors, nomogram models were built, and their predicting accuracy was assessed by using the area under the curves (AUCs). Result A total of 577 patients with RIAs were enrolled in this present study, 86 patients of them were identified as undergoing rebleeding after admission. Thirteen parameters were identified as significantly different between stable and rebleeding aneurysms in the primary cohort. Cox regression analysis demonstrated that six parameters, including hypertension [hazard ratio (HR), 2.54; P = 0.044], bifurcation site (HR, 1.95; P = 0.013), irregular shape (HR, 4.22; P = 0.002), aspect ratio (HR, 12.91; P < 0.001), normalized wall shear stress average (HR, 0.16; P = 0.002), and oscillatory stress index (HR, 1.14; P < 0.001) were independent risk factors related to the rebleeding after admission. Two nomograms were established, the nomogram including clinical, morphological, and hemodynamic features (CMH nomogram) had the highest predicting accuracy (AUC, 0.92), followed by the nomogram including clinical and morphological features (CM nomogram; AUC, 0.83), ELAPSS score (AUC, 0.61), and PHASES score (AUC, 0.54). The calibration curve for the probability of rebleeding showed good agreement between prediction by nomograms and actual observation. In the validation cohort, the discrimination of the CMH nomogram was superior to the other models (AUC, 0.93 vs. 0.86, 0.71 and 0.48). Conclusion We presented two nomogram models, named CMH nomogram and CM nomogram, which could assist in identifying the RIAs with high risk of rebleeding.

Abstract
Mortality after aneurysmal subarachnoid hemorrhage (aSAH) is augmented by rebleeding and delayed cerebral ischemia (DCI). A range of assays evaluating the dynamic process of blood coagulation, from activation of clotting factors to fibrinolysis, has emerged and a comprehensive review of hemostasis and fibrinolysis following aSAH may reveal targets of treatment. We conducted a systematic review of existing literature assessing coagulation and fibrinolysis following aSAH, but prior to treatment. PubMed, Embase, and Web of Science were searched on November 18, 2020, without time boundaries. In total, 45 original studies were eventually incorporated into this systematic review, divided into studies presenting data only from conventional or quantitative assays (n = 22) and studies employing dynamic assays (n = 23). Data from conventional or quantitative assays indicated increased platelet activation, whereas dynamic assays detected platelet dysfunction possibly related to an increased risk of rebleeding. Secondary hemostasis was activated in conventional, quantitative, and dynamic assays and this was related to poor neurological outcome and mortality. Studies systematically investigating fibrinolysis were sparse. Measurements from conventional or quantitative assays, as well as dynamic fibrinolysis assays, revealed conflicting results with normal or increased lysis and changes were not associated with outcome. In conclusion, dynamic assays were able to detect reduced platelet function, not revealed by conventional or quantitative assays. Activation of secondary hemostasis was found in both dynamic and nondynamic assays, while changes in fibrinolysis were not convincingly demonstrable in either dynamic or conventional or quantitative assays. Hence, from a mechanistic point of view, desmopressin to prevent rebleeding and heparin to prevent DCI may hold potential as therapeutic options. As changes in fibrinolysis were not convincingly demonstrated and not related to outcome, the use of tranexamic acid prior to aneurysm closure is not supported by this review.

Ultra-Early Induction of General Anesthesia for Reducing Rebleeding Rates in Patients with Aneurysmal Subarachnoid Hemorrhage. J Stroke Cerebrovasc Dis 2021; 30:105926. [PMID: 34171637 DOI: 10.1016/j.jstrokecerebrovasdis.2021.105926] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2021] [Revised: 05/16/2021] [Accepted: 05/24/2021] [Indexed: 01/02/2023] Open
Abstract
OBJECTIVE Rebleeding of aneurysmal subarachnoid hemorrhage (aSAH) is one of the significant risk factors for poor clinical outcome. The rebleeding risk is the highest during the acute phase with an approximate rebleeding rate of 9-17% within the first 24 h. Theoretically, general anesthesia can stabilize a patient's vital signs; however, its effectiveness as initial management for preventing post-aSAH rebleeding remains unclear. The purpose of this study was to determine the feasibility and safety of ultra-early general anesthesia induction for reducing the rebleeding rates among patients with aSAH. MATERIALS AND METHODS We retrospectively evaluated patients with aSAH who were admitted to our department between January 2013 and December 2019. All the patients underwent ultra-early general anesthesia induction as initial management regardless of their severity. We evaluated the rebleeding rate before definitive treatment, factors influencing rebleeding, and general anesthesia complications. RESULTS We included 191 patients with two-third of them having a poor clinical grade (World Federation of Neurological Society [WFNS] grade IV or V). The median duration from admission to general anesthesia induction was 22 min. Rebleeding before definitive treatment occurred in nine patients (4.7%). There were significant differences in the Glasgow Coma Scale score (p = 0.047), WFNS grade (p = 0.02), and dissecting aneurysm (p <0.001) between the rebleeding and non-rebleeding patients. There were no cases of unsuccessful tracheal intubation or rebleeding during general anesthesia induction. CONCLUSION Ultra-early general anesthesia induction could be performed safely in patients with aSAH, regardless of the WFNS grade; moreover, it resulted in lower rebleeding rate than that reported in previous epidemiological reports.

Cerebral hypoperfusion necessitating additional bypass following hunterian ligation of the internal carotid artery despite reassuring intraoperative challenges: Video case report. Surg Neurol Int 2021; 12:22.

Abstract
Background: Hunterian ligation has been adapted for complex intracranial aneurysm repair when other, more modern techniques are insufficient. Before drastic alteration of cerebral blood flow dynamics, intraoperative challenges and consideration of blood flow dynamics must be completed to ensure adequate perfusion postligation. On satisfaction, ligation may proceed; however, subtle changes related to hypoperfusion may not be immediately observed during intraoperative challenge under general anesthesia and/or before onset of the vasospasm window. Case Description: In this report, we describe a patient who presented with a Hunt-Hess Grade III subarachnoid hemorrhage (SAH), with a right internal carotid artery (ICA) occlusion and a ruptured giant left ICA aneurysm. Endovascular treatment of the aneurysm was aborted because the nominal, 9 mm diameter of the ICA was too large for any intracranial balloon or stent. Three days later, she underwent a left-sided “insurance” extracranial-tointracranial arterial bypass (EIAB) using the superficial temporal artery simultaneously with hunterian ligation of the left ICA following reassuring results on intraoperative occlusion challenge. Over several days, her neurologic condition declined concurrent with the vasospasm window, and a right-sided EIAB was required to augment vascular supply. Following a protracted hospital course, the patient became progressively more independent and is currently residing in an assisted living facility. Conclusion: We illustrate an ultimately successful microsurgical treatment option in the setting of acute SAH that highlights the importance of cerebrovascular reserve and blood flow replacement in the setting of a compromised circle of Willis, especially during the vasospasm window.

Abstract
BACKGROUND Rebleeding after aneurysmal subarachnoid hemorrhage (aSAH) confers a poor prognosis; however, risk factors and differential outcomes associated with early rebleeding in the first 24 h after symptom presentation are incompletely understood. METHODS A retrospective cohort study of all aSAH presenting to our institution between 2001 and 2016 was performed. Early rebleeding events were defined as clinical neurologic decline with radiographically confirmed acute intracranial hemorrhage within 24 h after symptom presentation. Univariate and multivariate logistic regression analyses were used to assess clinical associations, with a specific focus on baseline Glasgow Coma Score (GCS), World Federation of Neurosurgical Societies (WFNS), and modified Fisher scores. RESULTS Of 471 aSAH cases, 33 (7%) experienced early rebleeding. Multivariate regression identified extraventricular drain (EVD) placement (OR = 2.16, P = 0.04) and WFNS 3-5 (OR = 2.69, P = 0.02) as significant predictors of early rebleeding. Good functional outcomes were observed in 8 patients with early rebleeding (24%), all of whom underwent aneurysm treatment. Higher SAH grade prior to rebleeding (WFNS 3-5) was significantly associated with increased odds of an unfavorable functional outcome (OR = 8.09, P < 0.01). Anticoagulation, aneurysm size and location were not significantly associated with either early rebleeding incidence or functional outcome. CONCLUSIONS Early rebleeding in aSAH is associated with unfavorable functional outcomes. EVD placement and higher SAH grade on presentation appear to be significantly and independently associated with increased risk of rebleeding within first 24 h, as well as unfavorable long-term functional outcome; however, the clinical benefit of hyper-acute aneurysm treatment requires further investigation.

Abstract
BACKGROUND Recurrent bleeding from an intracranial aneurysm after subarachnoid hemorrhage (SAH) is associated with unfavorable outcome. Recurrent bleeding before aneurysm occlusion can be performed occurs in up to one in five patients and most often happens within the first 6 h after the primary hemorrhage. Reducing the rate of recurrent bleeding could be a major factor in improving clinical outcome after SAH. Tranexamic acid (TXA) reduces the risk of recurrent bleeding but has thus far not been shown to improve functional outcome, probably because of a higher risk of delayed cerebral ischemia (DCI). To reduce the risk of ultraearly recurrent bleeding, TXA should be administered as soon as possible after diagnosis and before transportation to a tertiary care center. If TXA is administered for a short duration (i.e., < 24 h), it may not increase the risk of DCI. The aim of this paper is to present in detail the statistical analysis plan (SAP) of the ULTRA trial (ULtra-early TRranexamic Acid after Subarachnoid Hemorrhage), which is currently enrolling patients and investigating whether ultraearly and short-term TXA treatment in patients with aneurysmal SAH improves clinical outcome at 6 months. METHODS/DESIGN The ULTRA trial is a multicenter, prospective, randomized, open, blinded endpoint, parallel-group trial currently ongoing at 8 tertiary care centers and 16 of their referral centers in the Netherlands. Participants are randomized to standard care or to receive TXA at a loading dose of 1 g, immediately followed by 1 g every 8 h for a maximum of 24 h, in addition to standard care, as soon as SAH is diagnosed. In the TXA group, TXA administration is stopped immediately prior to treatment (coil or clip) of the causative aneurysm. Primary outcome is the modified Rankin Scale (mRS) score at 6 months after SAH, dichotomized into good (mRS 0-3) and poor (mRS 4-6) outcomes, assessed blind to treatment allocation. Secondary outcomes include case fatalities at 30 days and at 6 months and causes of poor clinical outcome. Safety outcomes are recurrent bleeding, DCI, hydrocephalus, per-procedural complications, and other complications such as infections occurring during hospitalization. Data analyses will be according to this prespecified SAP. TRIAL REGISTRATION Netherlands Trial Register, NTR3272. Registered on 25 January 2012. ClinicalTrials.gov, NCT02684812.

Abstract
BACKGROUND Little is known regarding functional outcome following poor-grade (World Federation of Neurosurgical Societies grades IV and V) aneurysmal subarachnoid hemorrhage (aSAH), especially in individuals treated aggressively in the early phase after ictus. METHODS We provided patients with aSAH with ultra-early definitive treatment, coiling or clipping, within 6 hours from arrival as per protocol. We classified the patients into 3 groups according to their computed tomography findings: Group 1, intraventricular hemorrhage with obstructive hydrocephalus; Group 2, massive intracerebral hemorrhage with brain herniation; and Group 3, neither Group 1 nor Group 2. We retrospectively evaluated patients with poor-grade aSAH who were admitted to our department between January 2013 and December 2016. We evaluated functional outcome at 6 months, defining modified Rankin Scale (mRS) scores of 0-2 as good and those of 3-6 as poor outcomes. RESULTS A good functional outcome was observed in 39.4% (28/71) of all cases. All-cause mortality at 6 months was 15.5% (11/71). A good outcome in Group 3 was significantly higher than that in the other two groups (Group 1 and 2 vs. Group 3, 20.8% vs. 48.9%, p = 0.02), even after adjustment with a multiple logistic regression analysis (odds ratio 6.1, 95% confidence interval 1.1 to 34.8). CONCLUSIONS Approximately 40% of patients with poor-grade aSAH became functionally independent, and approximately half of the patients with poor-grade aSAH who had neither intraventricular hemorrhage with obstructive hydrocephalus nor with brain herniation had good functional outcomes. Although further trials are required to confirm our results, ultra-early surgery may be considered for patients with poor-grade aSAH.

Abstract
OBJECTIVE Aneurysm rebleeding is a major cause of death and morbidity in patients with aneurysmal subarachnoid hemorrhage (SAH). Recognizing the predictors of rebleeding might help to identify patients who will benefit from acute management. This study was performed to investigate the predictors of aneurysm rebleeding and their impact on clinical outcomes in the preoperative, intraoperative, and postoperative periods. METHODS The incidence of rebleeding, demographic data, and clinical data from 4933 patients with aneurysmal SAH beginning in the year 2000 were retrospectively analyzed in the Nagasaki SAH Registry Study. The authors performed multiple logistic regression analyses to identify the risk factors contributing to rebleeding and outcome after SAH. RESULTS Preoperative rebleeding occurred in 7.2% of patients. Patient age (p = 0.01), multiple aneurysms (p < 0.01), aneurysm size (p < 0.0001), and heart disease (p = 0.03) were significantly associated with preoperative rebleeding. Conversely, intraoperative rebleeding occurred in 11.2% of patients. Aneurysm location (anterior communicating artery [ACoA]), family history (p = 0.02), preoperative rebleeding (p < 0.01), and clipping/coiling (p < 0.0001) were significantly associated with intraoperative rebleeding. Interaction analysis showed that clipping significantly affected intraoperative rebleeding at the ACoA (OR 4.00; 95% CI 1.82-8.80; p < 0.001). Postoperative rebleeding occurred in 2.4% of patients. Coiling/clipping (p < 0.0001) and intraoperative rebleeding (p < 0.01) were significantly associated with postoperative rebleeding. Rebleeding in all time periods examined significantly contributed to the clinical outcome after SAH. CONCLUSIONS Aneurysm rebleeding after SAH has specific characteristics in the preoperative, intraoperative, and postoperative periods, and all of these characteristics contribute to the clinical outcome. The ACoA has a higher risk of intraoperative rebleeding, and endovascular coiling could be a good candidate in terms of techniques for preventing intraoperative rebleeding, although complete aneurysm obliteration should be accomplished.

Abstract
BACKGROUND The benefit of surgical treatment of ruptured aneurysms is well established. OBJECTIVE To determine whether ultra-early ruptured aneurysm treatment leads to not only improved outcomes but also reduced hospitalization cost. METHODS Using 2008-2011 Nationwide Inpatient Sample data, we analyzed demographic, clinical, and hospital factors for nontraumatic subarachnoid hemorrhage (SAH) patients who were "directly" admitted to the treating hospital where they underwent intervention (clipping/coiling). Patients treated on the day of admission (day 0) formed the ultra-early cohort; others formed the deferred treatment cohort. All Patient Refined Diagnosis-Related Groups were also included in regression analyses. RESULTS A total of 17 412 patients were directly admitted to a hospital following nontraumatic SAH where they underwent intervention (clipping/coiling). Mean patient age was 53.87 yr (median 53.00, standard deviation 14.247); 68.3% were women (n = 11 893). A total of 6338 (36.4%) patients underwent treatment on the day of admission (ultra-early). Patients who underwent treatment on day 0 had significantly more routine discharge dispositions than those treated >admission day 0 (P < .0001). In regression analysis, treatment on day 0 was protective against other than routine discharge disposition outcome (P < .0001; odds ratio 0.657; 95% confidence interval 0.614-0.838). Total cost incurred by hospitals was $4.36 billion. Mean cost of hospital charges in the ultra-early cohort was $239 126.05, which was significantly lower than that for the cohort treated >day 0 ($272 989.56, P < .001), Mann-Whitney U-test). Performance of an intervention on admission day 0 was protective against higher hospitalization cost (P < .0001; odds ratio 0.811; 95% confidence interval 0.732-0.899). CONCLUSION Ultra-early treatment of ruptured aneurysms is significantly associated with better discharge disposition and decreased hospitalization cost.

Abstract
OBJECTIVEFluctuations in patient serum sodium levels are common after aneurysmal subarachnoid hemorrhage (aSAH), but their effect on patient outcome is not well described in the literature. The goal of this work was to better characterize the relationship between fluctuations in serum sodium levels, outcome, and the development of delayed cerebral ischemia (DCI) after aSAH.METHODSThe authors performed a post hoc analysis of data from the Clazosentan to Overcome Neurological Ischemia and Infarction Occurring After Subarachnoid Hemorrhage (CONSCIOUS-1) trial. Patients had their serum sodium values recorded daily for 14 days post-aSAH. Average and average absolute daily differences in sodium levels were calculated for each patient based on 3 reference points: admission sodium levels, a normal sodium level (defined as 140 mmol/L), and the previous day’s sodium level. These variables were also calculated for the classic “vasospasm window” (days 3–12) post-aSAH. A stepwise logistic regression model, locally weighted scatterplot smoothing curves, and receiver operator characteristic curve analysis were used to evaluate the relationship between alterations in serum sodium levels and clinical outcome or the development of DCI after aSAH. Poor outcome was defined as a modified Rankin Scale (mRS) score of > 2 at 3 months.RESULTSThe average daily difference in sodium values from baseline (p < 0.001), average daily difference from a normal sodium level (p < 0.001), average absolute daily difference from a normal sodium level (p = 0.015), and average absolute daily difference from the previous day’s sodium level (p = 0.017) were significant predictors of poor outcome in a stepwise multivariate regression model. There was a trend toward significance for average absolute daily difference from admission sodium levels during the vasospasm window as an independent predictor of DCI (p = 0.052). There was no difference in the predictive capacity for DCI when sodium fluctuations from post-aSAH days 1–14 were compared with those from the classic vasospasm window (days 3–12).CONCLUSIONSFluctuations in serum sodium levels may play a role in clinical outcome and the development of DCI after aSAH. The timing of these fluctuations appears to have no significant effect on the development of DCI.

Abstract
ObjectiveDelayed cerebral ischemia (DCI) is strongly associated with poor outcome after subarachnoid hemorrhage (SAH). Cerebral vasospasm is a major contributor to DCI and requires special attention. To evaluate the effect of vasospasm management on SAH outcome, we performed a pooled analysis of 2 observational SAH cohorts.MaterialsData from 2 institutional databases with consecutive patients with SAH treated between 2005 and 2012 were pooled. The effect of 2 institutional standards of conservative and endovascular vasospasm treatment (EVT) on the rates of DCI (new cerebral infarcts not visible on the post-treatment imaging) and unfavorable outcome (modified Rankin Scale score >2) at 6 months follow-up was analyzed.ResultsThe final analysis included 1,057 patients with SAH. There was no difference regarding demographic (age and sex), clinical (Hunt & Hess grades, acute hydrocephalus, treatment modality, and infections), and radiographic (Fisher grades and aneurysm location) characteristics of the populations. However, there was a significant difference in the rate (24.4% [121/495] vs 14.4% [81/562], p < 0.0001) and timing (first treatment on day 6 vs 8.9 after SAH, p < 0.0001) of EVT. The rates of DCI (20.8% vs 29%, p = 0.0001) and unfavorable outcome (44% vs 50.6%, p = 0.04) were lower in the cohort with more frequent and early EVT. Multivariate analysis confirmed independent effect of EVT standard on DCI risk and outcome.ConclusionsA preventive strategy utilizing frequent and early EVT seems to reduce the risk of DCI in patients with SAH and improve their functional outcome. We recommend prospective evaluation of the value of preventive EVT strategy on SAH.Classification of evidenceThis study provides Class III evidence that for patients with SAH, a frequent and early EVT to treat vasospasm reduces the risk of DCI and improves functional outcome.

Abstract
OBJECTIVE Patients suffering from aneurysmatic Subarachnoid Hemorrhage (SAH) may present with a variety of symptoms. The aim of this study is to evaluate the spectrum of misdiagnoses and to analyze the significance of delay of correct diagnosis on the clinical outcome. METHODS The data was collected prospectively from 2003 to 2013. Patients diagnosed with disease different from aneurysmal SAH by the initially treating physician, and admitted to our department with a delay of at least 24 h after the beginning of the symptoms, were included in this study. We analyzed the various diagnoses that were ascertained instead of SAH and which medical specialty had provided them. RESULTS Overall 704 patients were treated with acute SAH. The inclusion criteria were matched in 76 patients (13.7%). Eleven specialties were involved in the initial patients' treatment. The time interval between initial symptoms and neurosurgical admission varied enormously. Statistically, higher Hunt & Hess score did not lead to an earlier diagnosis (p = 0.56) nor did localisation of the aneurysm (p = 0.75). Lower Fisher score was led to delayed diagnosis (p = 0.02). Delay of diagnosis was not significantly associated with the outcome (p = 0.08) whereas Hunt & Hess grade on admission was a strong predictor for bad outcome (p = 0.00001) as was cerebral vasospasm on the first angiogram (p < 0.05). CONCLUSION A straightforward diagnosis of SAH despite diffuse and unspecific symptoms is crucial for the successful treatment of these patients, especially with high grade SAH.

Abstract
Background Recurrent bleeding is one of the major causes of morbidity and mortality in patients with aneurysmal subarachnoid hemorrhage (aSAH). Antifibrinolytic therapy is known to reduce recurrent bleeding, however, its beneficial effect on outcome remains unclear. The effect of treatment with tranexamic acid (TXA) until aneurysm treatment on clinical outcome is evaluated. Methods Patients with an aSAH from two high-volume tertiary referral treatment centers in the Netherlands, Academic Medical Center (AMC) and Radboud University Medical Center (RUMC), between January 2012 and December 2015 were included. Patients were classified into one of two groups; standard treatment or TXA treatment. Demographic and clinical characteristics, in-hospital complications and clinical outcome were compared between the two groups. Multivariate logistic regression was used to adjust for the influence of treatment center and baseline differences. Results Standard treatment was given in 509 patients, and 119 patients received additional TXA therapy before aneurysm occlusion. Patients treated with TXA did not experience less recurrent bleeding adjusted or unadjusted for treatment center (adjusted odds ratio [aOR] 0.80, 95% confidence interval [95% CI]: 0.37–1.73). In-hospital mortality, was significantly lower in the TXA group than the standard care group (adjusted OR [aOR] 0.42, 95% CI: 0.20–0.85). Poor outcome (mRS 4–6) assessed after six months was not different between treatment groups (aOR 1.05, 95% CI: 0.64–1.74). Conclusions Pooled data from two high-volume treatment centers did not show improved clinical outcome after additional TXA treatment in aSAH patients. However, TXA treatment was associated with a decrease in mortality.

Abstract
Background and purpose: Emerging evidence suggests that systemic inflammation is associated with the pathophysiological process of delayed cerebral ischemia (DCI) after aneurysmal subarachnoid hemorrhage (aSAH). This study aimed to investigate the association of white blood cell (WBC) count and neutrophil-to-lymphocyte ratio (NLR) with the occurrence of DCI in SAH patients. Methods: A total of 122 patients diagnosed with aSAH within 72 h of onset were retrospectively enrolled. The count of WBC, neutrophil count (NC), and lymphocyte (LC) was collected on admission. Computed tomography perfusion was performed within 7 days after SAH. The occurrence of DCI was recorded during the hospitalization. Results: Among enrolled patients, 43 (35.2%) developed DCI during hospitalization. Patients who developed DCI had a higher count of WBC, NC, and NLR as well as a lower count of LC. NC and NLR were independently associated with the occurrence of DCI, while NLR was the best predictive parameter according to the receiver operating characteristic curve. Moreover, there was a strong correlation between NLR and mean cerebral blood flow, mean transit time and mean time to peak. Conclusion: Leukocytosis is an early pathology of SAH, and NLR may be a practical predictor for the occurrence of DCI in SAH patients.

Abstract
BACKGROUND Successful endovascular management of aneurysmal subarachnoid hemorrhage (aSAH) requires timely access to substantial resources. Prior studies suggest an association between time to treatment and patient outcome. Patients treated at safety-net hospitals are thought to be particularly vulnerable to disparities in access to interventions that require substantial technologic resources. We hypothesized that patients with aSAH treated at safety-net hospitals are at greater risk for delayed access to endovascular treatment. METHODS Adults undergoing endovascular coiling procedures between 2002 and 2011 in the Nationwide Inpatient Sample were included. Hospitals in the quartile with the highest proportion of Medicaid or uninsured patients were defined as safety-net hospitals. A multivariate model including patient-level and hospital-level factors was constructed to permit analysis of delays in endovascular treatment (defined as time to treatment >3 days). RESULTS Analysis included 7109 discharges of patients with aSAH undergoing endovascular coil embolization procedures from 2002 to 2011. Median time to coil embolization in all patients was 1 day; 10.1% of patients waited >3 days until treatment. In multivariate analysis, patients treated at safety-net hospitals were more likely to have a prolonged time to coil embolization (odds ratio = 1.32, P < 0.01) compared with patients treated at low-burden hospitals. CONCLUSIONS After controlling for patient and hospital factors, individuals with aSAH treated at safety-net hospitals from 2002 to 2011 were more likely to have a delay to endovascular coil embolization than individuals treated at non-safety-net hospitals. This disparity could affect patient outcomes.

Abstract
Fibrinolysis is a physiologic component of hemostasis that functions to limit clot formation. However, after trauma or surgery, excessive fibrinolysis may contribute to coagulopathy, bleeding, and inflammatory responses. Antifibrinolytic agents are increasingly used to reduce bleeding, allogeneic blood administration, and adverse clinical outcomes. Tranexamic acid is the agent most extensively studied and used in most countries. This review will explore the role of fibrinolysis as a pathologic mechanism, review the different pharmacologic agents used to inhibit fibrinolysis, and focus on the role of tranexamic acid as a therapeutic agent to reduce bleeding in patients after surgery and trauma.

Abstract
BACKGROUND AND PURPOSE To identify predictors of in-hospital mortality in patients with aneurysmal subarachnoid hemorrhage and to estimate their impact. METHODS Retrospective analysis of prospective data from a nationwide multicenter registry on all aneurysmal subarachnoid hemorrhage cases admitted to a tertiary neurosurgical department in Switzerland (Swiss SOS [Swiss Study on Aneurysmal Subarachnoid Hemorrhage]; 2009-2015). Both clinical and radiological independent predictors of in-hospital mortality were identified, and their effect size was determined by calculating adjusted odds ratios (aORs) using multivariate logistic regression. Survival was displayed using Kaplan-Meier curves. RESULTS Data of n=1866 aneurysmal subarachnoid hemorrhage patients in the Swiss SOS database were available. In-hospital mortality was 20% (n=373). In n=197 patients (10.6%), active treatment was discontinued after hospital admission (no aneurysm occlusion attempted), and this cohort was excluded from analysis of the main statistical model. In the remaining n=1669 patients, the rate of in-hospital mortality was 13.9% (n=232). Strong independent predictors of in-hospital mortality were rebleeding (aOR, 7.69; 95% confidence interval, 3.00-19.71; P<0.001), cerebral infarction attributable to delayed cerebral ischemia (aOR, 3.66; 95% confidence interval, 1.94-6.89; P<0.001), intraventricular hemorrhage (aOR, 2.65; 95% confidence interval, 1.38-5.09; P=0.003), and new infarction post-treatment (aOR, 2.57; 95% confidence interval, 1.43-4.62; P=0.002). CONCLUSIONS Several-and among them modifiable-factors seem to be associated with in-hospital mortality after aneurysmal subarachnoid hemorrhage. Our data suggest that strategies aiming to reduce the risk of rebleeding are most promising in patients where active treatment is initially pursued.

Abstract
Objective To review the published literature on the clinical application of cerebral microdialysis (CMD) in aneurysmal subarachnoid hemorrhage (SAH) patients and to summarize the evidence relating cerebral metabolism to pathophysiology, secondary brain injury, and outcome. Methods Study selection: Two reviewers identified all manuscripts reporting on the clinical use of CMD in aneurysmal SAH patients from MEDLINE. All identified studies were grouped according to their focus on brain metabolic changes during the early and subacute phase after SAH, their association with mechanisms of secondary brain injury and outcome. Results The review demonstrated: (1) limited literature is available in the very early phase before the aneurysm is secured. (2) Brain metabolic changes related to early and delayed secondary injury mechanisms may be used in addition to other neuromonitoring parameters in the critical care management of SAH patients. (3) CMD markers of ischemia may detect delayed cerebral ischemia early (up to 16 h before onset), underlining the importance of trend analysis. (4) Various CMD-derived parameters may be associated with patient outcome at 3–12 months, including CMD-lactate-to-pyruvate-ratio, CMD-glucose, and CMD-glutamate. Conclusion The clinical use of CMD is an emerging area in the literature of aneurysmal SAH patients. Larger prospective multi-center studies on interventions based on CMD findings are needed.

Abstract
The purpose of this article is to provide the reader, a seasoned radiologist, a budding resident, or a curious practitioner, the background necessary to accurately and swiftly interpret a head computed tomography in the emergency setting. At the very least, being able to generate a reasonable differential diagnosis is the aim and will be accomplished by describing not only features of classic neurologic emergencies but also the possible traps to which one may fall prey. Images will be used to illustrate cases, and the reader will be instructed when other imaging modalities may be required to clarify diagnoses.

World Neurosurg 2017; 107:588-596. [PMID: 28823655 DOI: 10.1016/j.wneu.2017.08.005] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2017] [Revised: 07/28/2017] [Accepted: 08/01/2017] [Indexed: 10/19/2022]
Abstract
OBJECTIVE Distal anterior cerebral artery (DACA) aneurysms are rare, and their treatment by either surgical clipping or endovascular treatment poses technical difficulties. Earlier studies have reported higher complication rates in DACA aneurysms compared with other aneurysms in the circle of Willis. Therefore, endovascular management of DACA aneurysms still remains a challenge. The aim of this report is to review clinical presentation, angiographic presentation of DACA aneurysms, complications, and outcome of their endovascular treatment in our institutional experience. METHODS A retrospective review of 186 patients with intracranial aneurysms treated with endovascular management from September 2009 to December 2013 in the Max Superspecialty Hospital, New Delhi, India, 11 patients (5.9%) with 12 DACA aneurysms were studied retrospectively. We report the clinical presentations, cerebral angiographic findings, endovascular treatment, complications, and outcomes. The clinical and angiographic outcomes were assessed using modified Rankin scales and the Raymond scale, respectively. RESULTS Of 11 patients, 54.5% were female and 45.5% were male; the mean age was 48.4 years (range, 33-65 years). All patients had subarachnoid hemorrhage that indicated ruptured DACA aneurysm. All the DACA aneurysms were small. Postcoiling angiograms showed complete occlusion in 9 patients. Two patients had intraprocedural aneurysm rupture but without any clinical sequelae, and 1 patient had thrombus formation, which was thrombolysed at the end of coiling. All patients had good outcomes. CONCLUSIONS Our experience with 11 patients showed that endovascular management of small DACA aneurysms, though associated with higher intraprocedural events, is associated with good outcome.

Abstract
OBJECTIVEAneurysmal rebleeding before definitive obliteration of the aneurysm is a cause of mortality and morbidity. There are limited data on the role of short-term antifibrinolytic therapy among patients undergoing endovascular intervention.METHODSAll consecutive patients receiving endovascular therapy for their ruptured saccular aneurysm at the authors' institution between 2000 and 2011 were included in this study. These patients underwent endovascular coiling of their aneurysm within 72 hours of admission. In patients receiving ε-aminocaproic acid (EACA), the EACA administration was continued until the time of the endovascular procedure. Complications and clinical outcomes of endovascular treatment after aneurysmal subarachnoid hemorrhage (aSAH) were compared between EACA-treated and untreated patients.RESULTSDuring the 12-year study period, 341 patients underwent endovascular coiling. Short-term EACA treatment was administered in 146 patients and was withheld in the other 195 patients. EACA treatment did not change the risk of preinterventional rebleeding in this study (OR 0.782, 95% CI 0.176–3.480; p = 0.747). Moreover, EACA treatment did not increase the rate of thromboembolic events. On the other hand, patients who received EACA treatment had a significantly longer duration of hospital stay compared with their counterparts who were not treated with EACA (median 19 days, interquartile range [IQR] 12.5–30 days vs median 14 days, IQR 10–23 days; p < 0.001). EACA treatment was associated with increased odds of shunt requirement (OR 2.047, 95% CI 1.043–4.018; p = 0.037) and decreased odds of developing cardiac complications (OR 0.138, 95% CI 0.031–0.604; p = 0.009) and respiratory insufficiency (OR 0.471, 95% CI 0.239–0.926; p = 0.029). Short-term EACA treatment did not affect the Glasgow Outcome Scale score at discharge, 6 months, or 1 year following discharge.CONCLUSIONSIn this study, short-term EACA treatment in patients who suffered from aSAH and received endovascular aneurysm repair did not decrease the risk of preinterventional rebleeding or increase the risk of thrombotic events. EACA did not affect outcome. Randomized clinical trials are required to provide robust clinical recommendation on short-term use of EACA.

Abstract
Background Subarachnoid hemorrhage (SAH) is associated with higher mortality in the acute phase than other stroke types. There is a particular risk of early and devastating re-bleeding. Patients therefore need urgent assessment in a neurosurgical department, and the shorter the time from symptom onset to diagnosis the better. Case presentation The Norwegian Acute Stroke Pre-hospital Project (NASPP) has developed a Mobile Stroke Unit (MSU) model, which is staffed with anesthesiologists also trained in pre-hospital clinical assessment of acute stroke patients and interpretation of computerized tomography (CT). The MSU was operated on-call from the local dispatch center in a rural area 45–160 km away from a neurosurgical department. Two patients presented with clinical symptoms and signs compatible with SAH. In both cases, the CT examination confirmed the diagnosis of SAH. Both were transported directly from patient location to the regional neurosurgical department, saving at least 2–2.5 h of pre-neurosurgical time. Conclusion The Norwegian MSU model staffed with anesthesiologists can rapidly establish an exact diagnosis of SAH, which in a rural area significantly reduces time to neurosurgical care. Trial registration Study data are retrospectively registered in ClinicalTrail.gov.

Abstract
Aneurysmal subarachnoid hemorrhage (SAH) is a neurological emergency with high risk of neurological decline and death. Although the presentation of a thunderclap headache or the worst headache of a patient's life easily triggers the evaluation for SAH, subtle presentations are still missed. The gold standard for diagnostic evaluation of SAH remains noncontrast head computed tomography (CT) followed by lumbar puncture if the CT is negative for SAH. Management of patients with SAH follows standard resuscitation of critically ill patients with the emphasis on reducing risks of rebleeding and avoiding secondary brain injuries.

Abstract
BACKGROUND Aneurysmal rebleed is the most dreaded complication following subarachnoid hemorrhage. Being a cause of devastating outcome, the stratification of risk factors can be used to prioritize patients, especially at high volume centers. METHOD A total of 99 patients with aneurysmal rebleed were analyzed in this study both prospectively and retrospectively from August 2010 to July 2014. In the control group, 100 patients were selected randomly from the patient registry. A total of 25 variables from the demographic, historical, clinical and radiological data were compared and analyzed by univariate and multivariate logistic regression analysis. RESULTS Significant independent predictors of aneurysm rebleed were the presence of known hypertension (p = 0.023), diastolic blood pressure of >90 mmHg on admission (p = 0.008); presence of loss of consciousness (p = 0.013) or seizures (p = 0.002) at first ictus; history of warning headaches (p = 0.005); higher Fisher grade (p < 0.001); presence of multiple aneurysms (p = 0.021); irregular aneurysm surface (0.002). CONCLUSIONS Identification of high risk factors can help in stratifying patients in the high risk group. The risk stratification strategy with early intervention can prevent rebleeds. This in turn may translate into better outcomes of patients with intracranial aneurysms.

Abstract
OBJECTIVE Aneurysmal rebleeding is a major cause of morbidity and mortality after aneurysmal subarachnoid hemorrhage (aSAH); however, limited data on severity of rebleeding and outcomes after severe rebleeding are available. We aimed to determine predictors of good outcome and mortality after severe rebleeding. MATERIALS AND METHODS In a multicenter poor-grade aneurysm study, 60 patients with severe rebleeding, defined as new hemorrhage with poor clinical condition caused by rebleeding, were identified. Good functional outcome was defined as a modified Rankin scale (mRS) of ≤2, and mortality was defined as a mRS of 6. Multivariate logistic analyses were used to determine predictors of good outcome and mortality. RESULTS Of the 58 patients included in this report, 24 (41.3%) patients experienced rebleeding within 24h after ictus. 42 (72.4%) patients had died at 12 months. The rate of good outcome increased from 5.2% at discharge to 13.8% at 6 months and 19.0% at 12 months. In multivariate analysis, World Federation of Neurosurgical Societies (WFNS) grade IV after rebleeding (P=0.007) and aggressive treatment (P=0.039) were independently associated with good outcome. A higher modified Fisher grade before rebledding (P=0.040), larger aneurysms (P=0.005), and lower Glasgow coma score after rebleeding (P=0.003) were independently associated with increased mortality. CONCLUSIONS A better clinical condition after rebleeding were independently associated with good outcome and inversely associated with morality after severe rebleeding. Despite high mortality of rebleeding, patients with WFNS grade IV treated with aggressive treatment were more likely to have good outcomes regardless of their condition before rebleeding.

Abstract
OPINION STATEMENT Non-traumatic intracranial hemorrhage (i.e. intracerebral hemorrhage [ICH] and subarachnoid hemorrhage [SAH]) are more life threatening and least treatable despite being less common than ischemic stroke. Elevated blood pressure (BP) is a strong predictor of poor outcome in both ICH and SAH. Data from a landmark clinical trial INTERACT 2, wherein 2839 participants enrolled with spontaneous ICH were randomly assigned to receive intensive (target systolic BP <140 mmHg) or guideline recommended BP lowering therapy (target systolic BP <180 mmHg), showed that intensive BP lowering was safe, and more favorable functional outcome and better overall health-related quality of life were seen in survivors in the intensive treatment group. These results contributed to the shift in European and American guidelines towards more aggressive early management of elevated BP in ICH. In contrast, the treatment of BP in SAH is less well defined and more complex. Although there is consensus that hypertension needs to be controlled to prevent rebleeding in the acute setting, induced hypertension in the later stages of SAH has questionable benefits.

Abstract
Aneurysmal subarachnoid haemorrhage is a neurological syndrome with complex systemic complications. The rupture of an intracranial aneurysm leads to the acute extravasation of arterial blood under high pressure into the subarachnoid space and often into the brain parenchyma and ventricles. The haemorrhage triggers a cascade of complex events, which ultimately can result in early brain injury, delayed cerebral ischaemia, and systemic complications. Although patients with poor-grade subarachnoid haemorrhage (World Federation of Neurosurgical Societies 4 and 5) are at higher risk of early brain injury, delayed cerebral ischaemia, and systemic complications, the early and aggressive treatment of this patient population has decreased overall mortality from more than 50% to 35% in the last four decades. These management strategies include (1) transfer to a high-volume centre, (2) neurological and systemic support in a dedicated neurological intensive care unit, (3) early aneurysm repair, (4) use of multimodal neuromonitoring, (5) control of intracranial pressure and the optimisation of cerebral oxygen delivery, (6) prevention and treatment of medical complications, and (7) prevention, monitoring, and aggressive treatment of delayed cerebral ischaemia. The aim of this article is to provide a summary of critical care management strategies applied to the subarachnoid haemorrhage population, especially for patients in poor neurological condition, on the basis of the modern concepts of early brain injury and delayed cerebral ischaemia.
