Study on prognosis of acutely ruptured intracranial aneurysms (SPARTA): a protocol for a multicentre prospective cohort study. BMC Neurol 2024; 24:68. [PMID: 38368355 PMCID: PMC10873988 DOI: 10.1186/s12883-024-03567-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Accepted: 02/12/2024] [Indexed: 02/19/2024] Open
Abstract
BACKGROUND Ruptured intracranial aneurysms resulting in subarachnoid haemorrhage can be treated by open surgical or endovascular treatment. Despite multiple previous studies, uncertainties on the optimal treatment practice still exists. The resulting treatment variation may result in a variable, potentially worse, patient outcome. To better inform future treatment strategies, this study aims to identify the effectiveness of different treatment strategies in patients with ruptured intracranial aneurysms by investigating long-term functional outcome, complications and cost-effectiveness. An explorative analysis of the diagnostic and prognostic value of radiological imaging will also be performed. METHODS This multi-centre observational prospective cohort study will have a follow-up of 10 years. A total of 880 adult patients with a subarachnoid haemorrhage caused by a ruptured intracranial aneurysm will be included. Calculation of sample size (N = 880) was performed to show non-inferiority of clip-reconstruction compared to endovascular treatment on 1 year outcome, assessed by using the ordinal modified Rankin Scale. The primary endpoint is the modified Rankin Scale score and mortality at 1 year after the initial subarachnoid haemorrhage. Patients will receive 'non-experimental' regular care during their hospital stay. For this study, health questionnaires and functional outcome will be assessed at baseline, before discharge and at follow-up visits. DISCUSSION Despite the major healthcare and societal burden, the optimal treatment strategy for patients with subarachnoid haemorrhage caused by ruptured intracranial aneurysms is yet to be determined. Findings of this comparative effectiveness study, in which in-between centre variation in practice and patient outcome are investigated, will provide evidence on the effectiveness of treatment strategies, hopefully contributing to future high value treatment standardisation.

Abstract
BACKGROUND Aneurysmal subarachnoid hemorrhage (aSAH) imaging has been shown to correlate with prognosis. However, no numerical index of bleeding severity has been established. This study aimed to propose a new simple scoring system for computed tomography imaging of aSAH and to confirm its effectiveness in retrospective and prospective studies. METHODS We devised an image evaluation system as an objective index. This system was established by scoring six items, with a maximum total of 19 points. Using this score, named the Shinshu Aneurysmal Subarachnoid Hemorrhage Score (S-score), we performed a retrospective study of 210 patients with aSAH at a single institution to confirm its efficacy. Age and World Federation of Neurosurgical Societies grades were adopted as other verification items, and the modified Rankin Scale was used for prognostic evaluation. A multicenter prospective study was then conducted to examine the function of the score by examining 214 patients with aSAH. RESULTS In the retrospective study, the threshold of the S-score between good and poor prognoses was 9/19 points. The area under the curve by receiver operating characteristic analysis of the S-score was 0.819, suggesting efficacy, with an odds ratio (OR) of 1.291 (1.077-1.547). In the prospective study, the judgment capability of the S-score was evaluated with a sensitivity of 0.674, specificity of 0.881, positive predictive value of 0.789, negative predictive value of 0.804, false-positive ratio of 0.119, false-negative ratio of 0.325, positive likelihood ratio of 6.072, and negative likelihood ratio of 1.369. S-score showed a significant difference in prognosis. The OR was 1.183 (1.009-1.388). CONCLUSIONS The scoring system could contribute to patient prognosis assessment. S-score and its prognostic formulas may serve as an objective source of information in the development of clinical medicine.

ARQUIVOS DE NEURO-PSIQUIATRIA 2021; 79:759-765. [PMID: 34669812 DOI: 10.1590/0004-282x-anp-2020-0167] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Accepted: 12/07/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND Predictors of outcomes following endovascular treatment (ET) for aneurysmal subarachnoid hemorrhage (aSAH) are not well-defined. Identifying them would be beneficial in determining which patients might benefit from ET. OBJECTIVE To identify the predictive factors for poor outcomes following ET for aSAH. METHODS 120 patients with ruptured cerebral aneurysms underwent endovascular embolization between January 2017 and December 2018. Blood pressure variability was examined using the standard deviation of the 24-hour systolic blood pressure (24hSSD) and 24-hour diastolic blood pressure (24hDSD). Predictors were identified through univariate and multivariate regression analysis. All patients were followed up for three months. RESULTS At follow-up, 86 patients (71.7%) had good outcomes and 34 (28.3%) had poor outcomes. Patients with poor outcomes had significantly higher 24hSSD than those with good outcomes (19.3 ± 5.5 vs 14.1 ± 4.8 mmHg; P < 0.001). The 24hDSD did not differ significantly between patients with good outcomes and those with poor outcomes (9.5 ± 2.3 vs 9.9 ± 3.5 mmHg; P = 0.464). The following were significant risk factors for poor outcomes after endovascular embolization: age ≥ 65 years (odds ratio [OR] = 23.0; 95% confidence interval [CI]: 3.0-175.9; P = 0.002); Hunt-Hess grade 3-4 (OR = 6.8; 95% CI: 1.1-33.7; P = 0.039); Fisher grade 3-4 (OR = 47.1; 95% CI: 3.8-586.5; P = 0.003); postoperative complications (OR = 6.1; 95% CI: 1.1-34.8; P = 0.042); and 24hSSD ≥ 15 mmHg (OR = 14.9; 95% CI: 4.0-55.2; P < 0.001). CONCLUSION Elevated 24hSSD is a possibly treatable predictive factor for poor outcomes after ET for aSAH.

Abstract
Objective: The objective of the study was to evaluate the outcome and related factors in patients with aneurysmal subarachnoid hemorrhage (aSAH). Materials and Methods: Clinical data of 221 patients who were diagnosed with spontaneous SAH due to ruptured intracranial aneurysm and surgically treated at Vajira Hospital between January 2013 and May 2016 were retrospectively reviewed. Patient and aneurysm characteristics, clinical status at presentation, treatment, and status at discharge and 1 year after discharge were recorded. Outcomes 1 year after surgery were assessed using the Glasgow Outcome Scale (GOS). Patients were divided into two groups according to the GOS score: the favorable outcome group (GOS scores 4 and 5) and unfavorable outcome group (GOS scores 1–3). Results: Among the 221 study patients, 158 were classified in the favorable outcome group and 63 in the unfavorable outcome group. Patient age, Hunt and Hess grade, aneurysm size, use of Vitamin C solution irrigation in the subarachnoid space, and GOS score 1 year after surgery significantly differed between the two groups. Conclusions: Numerous factors analyzed in this study were significantly associated with 1-year outcome in surgically treated aSAH patients, including subarachnoid Vitamin C irrigation. Further study of subarachnoid Vitamin C irrigation is warranted.

Abstract
Background Physical restraint has been commonly indicated to patients with brain dysfunction in neurocritical care. The effect of physical restraints on outcomes of critically ill adults remains controversial as no randomized controlled trials have compared its safety and efficacy, and the association between physical restraint requirement and neurological outcome in patients with subarachnoid hemorrhage (SAH) has not been fully examined. The aim of this study was to examine the association between physical restraint requirement and neurological outcomes in patients with SAH. Methods A single-center, retrospective study was conducted on patients with acute phase SAH treated for > 72 h in the intensive care unit from 2014 to 2020. Patients were divided into three groups based on the amount of time required for physical restraint during the first 24–72 h after admission: no, intermittent, and continuous use of physical restraint. Unfavorable neurologic outcome, assessed using the modified Rankin scale upon hospital discharge, has been considered as primary end point. Results Overall, 101 patients were included in the study, with 52 patients (51.5%) having unfavorable neurological outcomes. Among them, 46 patients (45.5%) did not use physical restraint, and 55 (54.5%) patients used physical restraint during the first 24–72 h after admission: 26 (25.7%) intermittent and 29 (28.7%) continuous. Multivariable logistic regression analysis showed that continuous use of physical restraint during the first 24–72 h after admission was significantly associated with unfavorable neurological outcomes in patients with SAH (odds ratio, 3.54; 95% confidence interval, 1.05–13.06; p = 0.042) compared with no physical restraint. Conclusions Continuous use of physical restraint during the first 24–72 h after admission was more significantly associated with unfavorable neurological outcomes than no physical restraint among patients with SAH during the acute phase.

Effects of case volume and comprehensive stroke center capabilities on patient outcomes of clipping and coiling for subarachnoid hemorrhage. J Neurosurg 2021; 134:929-939.

Abstract
OBJECTIVEImproved outcomes in patients with subarachnoid hemorrhage (SAH) treated at high-volume centers have been reported. The authors sought to examine whether hospital case volume and comprehensive stroke center (CSC) capabilities affect outcomes in patients treated with clipping or coiling for SAH.METHODSThe authors conducted a nationwide retrospective cohort study in 27,490 SAH patients who underwent clipping or coiling in 621 institutions between 2010 and 2015 and whose data were collected from the Japanese nationwide J-ASPECT Diagnosis Procedure Combination database. The CSC capabilities of each hospital were assessed by use of a validated scoring system based on answers to a previously reported 25-item questionnaire (CSC score 1–25 points). Hospitals were classified into quartiles based on CSC scores and case volumes of clipping or coiling for SAH.RESULTSOverall, the absolute risk reductions associated with high versus low case volumes and high versus low CSC scores were relatively small. Nevertheless, in patients who underwent clipping, a high case volume (> 14 cases/yr) was significantly associated with reduced in-hospital mortality (Q1 as control, Q4 OR 0.71, 95% CI 0.55–0.90) but not with short-term poor outcome. In patients who underwent coiling, a high case volume (> 9 cases/yr) was associated with reduced in-hospital mortality (Q4 OR 0.69, 95% CI 0.53–0.90) and short-term poor outcomes (Q3 [> 5 cases/yr] OR 0.75, 95% CI 0.59–0.96 vs Q4 OR 0.65, 95% CI 0.51–0.82). A high CSC score (> 19 points) was significantly associated with reduced in-hospital mortality for clipping (OR 0.68, 95% CI 0.54–0.86) but not coiling treatment. There was no association between CSC capabilities and short-term poor outcomes.CONCLUSIONSThe effects of case volume and CSC capabilities on in-hospital mortality and short-term functional outcomes in SAH patients differed between patients undergoing clipping and those undergoing coiling. In the modern endovascular era, better outcomes of clipping may be achieved in facilities with high CSC capabilities.

Abstract
OBJECTIVE As shown in a previous study, aneurysm location seems to influence prognosis in patients with subarachnoid hemorrhage (SAH). We compared patients with ruptured aneurysms of anterior and posterior circulation, undergoing coil embolization, concerning differences in outcome and prognostic factors. METHODS Patients with SAH were entered into a prospectively collected database. We retrospectively identified 307 patients with aneurysms of the anterior circulation (anterior cerebral artery, carotid bifurcation, and middle cerebral artery) and 244 patients with aneurysms of the posterior circulation (aneurysms of the basilar artery, posterior inferior cerebellar artery, posterior communicating artery and posterior cerebral artery). All patients underwent coil embolization. The outcome was assessed using the modified Rankin Scale (mRS; favorable [mRS 0-2] vs. unfavorable [mRS 3-6]) 6 months after SAH. RESULTS In interventionally treated aneurysms of the anterior and posterior circulation, statistically significant risk factors for poor outcome were worse admission status and severe cerebral vasospasm. If compared with patients with ruptured aneurysms of the anterior circulation, patients with aneurysms of the posterior circulation had a significantly poorer admission status, and suffered significantly more often from an early hydrocephalus. Nonetheless, there were no differences in outcome or mortality rate between the two patient groups. CONCLUSION Patients with a ruptured aneurysm of the posterior circulation suffer more often from an early hydrocephalus and have a significantly worse admission status, possibly related to the untreated hydrocephalus. Nonetheless, the outcome and the mortality rate were comparable between ruptured anterior and posterior circulation aneurysms, treated by coil embolisation. Therefore, despite the poorer admission status of patients with ruptured posterior circulation aneurysms, treatment of these patients should be considered.

Abstract
OBJECTIVE This study investigates the effect of aneurysm circulation on mortality and patient outcomes after aneurysmal subarachnoid hemorrhage (SAH) within the United States. METHODS A retrospective cohort study was conducted using the Nationwide Inpatient Sample (NIS), a part of the Healthcare Cost and Utilization Project (HCUP), with ICD-10 codes for non-traumatic SAH between 2015-2016. Aneurysms were stratified as either anterior or posterior circulation. Multivariate logistic regression was used to find the impact of selected variables on the odds of mortality. RESULTS The NIS reported 1,892 cases of non-traumatic SAH within the study period that were predominantly anterior circulation (82.6%), female (68.6%), white (57.7%), with mean age of 59.07 years, and in-hospital mortality of 21.4%. Anterior circulation aneurysms were associated with lower severity of initial illness (p = 0.014) but higher likelihood of vasospasm (p = 0.0006) than those of the posterior circulation. In a multivariate logistic regression analysis, mortality was associated with posterior circulation aneurysms (OR: 1.42; CI 95% 1.005-20.10, p = 0.047), increasing age (OR: 1.035; 95% CI 1.022-1.049; p < 0.0001), and shorter hospital stays (OR: 0.7838; 95% CI 0.758-0.811; p < 0.0001). Smoking history (OR: 0.825; 95% CI 0.573-1.187, p > 0.05) and vasospasm (OR: 1.005; 95% CI 0.648-1.558; p > 0.05) were not significantly associated with higher odds of mortality. CONCLUSIONS Mortality following aneurysmal SAH is associated with posterior circulation aneurysms, and increasing age, but not smoking history or vasospasm. These findings may be useful for prognostication and counseling patients and families.

Abstract
BACKGROUND The Subarachnoid Hemorrhage International Trialists (SAHIT) repository is a collection of randomized clinical trials, prospective observational studies, and hospital registries that was used to create a predictive model of unfavorable outcome/mortality following aneurysmal SAH. OBJECTIVE To externally validate the SAHIT model using Barrow Ruptured Aneurysm Trial (BRAT) data, which was not included in the SAHIT repository. METHODS This is a post hoc analysis of the prospective, randomized BRAT. Three models were created: (1) Core (age, hypertension, World Federation of Neurosurgical Societies grade), (2) neuroimaging (aneurysm size/location, Fisher score), and (3) full model (model 1 and 2 plus treatment type). The performance of the models was evaluated by measures of model discrimination (area under the curve [AUC]) and model calibration (goodness of fit test, calibration in-the-large, calibration slope). RESULTS A total of 338 patients (average age 54 years; 67.7% good clinical grade; average aneurysm size 6.7 mm; 84.1% anterior circulation) were included. Due to a large number of crossovers, more aneurysms were clipped than coiled (67.5% vs 32.5%, respectively). A total of 10.1% of the patients died and 29.6% experienced an unfavorable outcome. For unfavorable outcome, the AUCs for the three models were: 0.728, 0.732, and 0.734, respectively. For mortality, the AUCs for the three models were: 0.721, 0.739, and 0.744, respectively. Overall, all models showed good calibration, and the measures of calibration fell within 95% CI of those produced in the SAHIT study. CONCLUSION Using the BRAT data, we have externally validated the SAHIT model for predicting unfavorable outcome and mortality after SAH. The model may be used to counsel patients and families on prognosis following aneurysmal SAH.

Abstract
BACKGROUND AND PURPOSE In patients with SAH, the amount of blood is strongly associated with clinical outcome. However, it is commonly estimated with a coarse grading scale, potentially limiting its predictive value. Therefore, we aimed to develop and externally validate prediction models for clinical outcome, including quantified blood volumes, as candidate predictors. MATERIALS AND METHODS Clinical and radiologic candidate predictors were included in a logistic regression model. Unfavorable outcome was defined as a modified Rankin Scale score of 4-6. An automatic hemorrhage-quantification algorithm calculated the total blood volume. Blood was manually classified as cisternal, intraventricular, or intraparenchymal. The model was selected with bootstrapped backward selection and validated with the R 2, C-statistic, and calibration plots. If total blood volume remained in the final model, its performance was compared with models including location-specific blood volumes or the modified Fisher scale. RESULTS The total blood volume, neurologic condition, age, aneurysm size, and history of cardiovascular disease remained in the final models after selection. The externally validated predictive accuracy and discriminative power were high (R 2 = 56% ± 1.8%; mean C-statistic = 0.89 ± 0.01). The location-specific volume models showed a similar performance (R 2 = 56% ± 1%, P = .8; mean C-statistic = 0.89 ± 0.00, P = .4). The modified Fisher models were significantly less accurate (R 2 = 45% ± 3%, P < .001; mean C-statistic = 0.85 ± 0.01, P = .03). CONCLUSIONS The total blood volume-based prediction model for clinical outcome in patients with SAH showed a high predictive accuracy, higher than a prediction model including the commonly used modified Fisher scale.

Abstract
Intracranial aneurysms (IA) are weakened outpouchings of the arterial wall in the cerebrovasculature. Rupture of an IA often leads to devastating consequences. The early identification of IA patients is crucial for management of their condition. A genetic variant at rs10230207, located nearby the HDAC9, TWIST1, and FERD3L genes, is associated with IA. HDAC9 is a class IIa histone deacetylase that mediates vascular smooth muscle cell dysfunction. TWIST1 is a mechanosensitive transcription factor and its expression is reduced in unstable carotid atherosclerotic plaques. In this study, the expression of the HDAC9, TWIST1, and FERD3L genes was characterized and associated with the presence of the rs10230207 genetic variant. Allelic discrimination and gene expression analysis were performed using lymphoblasts from 85 population controls and 109 IA patients. Subjects that were heterozygous (GT) within rs10230207 were 4.32 times more likely to have an IA than those that were homozygous for the reference allele (GG; 95%CI 1.23 to 14.16). Subjects that were homozygous (TT) were 8.27 times more likely to have an IA than those that were GG (95%CI 2.45 to 27.85). While the presence of the risk allele was not associated with changes in FERD3L gene expression, the risk allele was associated with increased HDAC9 and decrease in TWIST1 mRNA expression. The significant inverse correlation between HDAC9 and TWIST1 gene expression suggests that changes in the expression of both of genes may contribute to the formation of IAs.

Abstract
OBJECTIVESubarachnoid hemorrhage (SAH) is treated with either surgical clipping or endovascular coiling, though the latter is the preferred treatment method given its more favorable functional outcomes. However, neuropsychological functioning after treatment is rarely taken into account. In this meta-analysis, the authors synthesized relevant data from the literature and compared neuropsychological functioning in patients after coiling and clipping of SAH. They hypothesized that the coiled patients would outperform the clipped patients; that group differences would be greater with higher posterior circulation rupture rates, in older patients, and in more recent publications; that group differences would be smaller with greater rates of middle cerebral artery (MCA) rupture; and that anterior communicating artery (ACoA) rupture rates would not influence effect sizes.METHODSThe MEDLINE, Embase, and PsycINFO databases were searched for clinical studies that compared neuropsychological functioning after either endovascular coiling or surgical clipping for SAH. Hedge's g and 95% confidence intervals were calculated using random effects models. Patients who had undergone coiling or clipping were compared on test performance in 8 neuropsychological domains: executive functions, language, attention/processing speed, verbal memory, visual memory, spatial memory, visuospatial functions, and intelligence. Patients were also compared with healthy controls, and meta-regressions were used to explore the relation between effect sizes and publication year, delay between treatment and neuropsychological testing, mean patient age, and rates of posterior circulation, ACoA, and MCA ruptures.RESULTSThirteen studies with 396 clipped cases, 314 coiled cases, and 169 healthy controls were included in the study. The coil-treated patients outperformed the clip-treated patients on executive function (g = 0.17, 95% CI 0.08–0.25) and language tests (g = 0.23, 95% CI 0.07–0.39), and all patients were impaired relative to healthy controls (g ranged from −0.93 to −0.29). Coiled patients outperformed clipped patients to a greater degree in more recent publications, over longer posttreatment testing delays, and among older patients. Higher rates of posterior circulation and MCA aneurysms were associated with smaller group differences, while ACoA rupture rates did not influence effect sizes.CONCLUSIONSCoiling of SAH may promote superior neuropsychological functioning under certain circumstances and could have applications for the specialized care of SAH patients.

Abstract
OBJECTIVE Overlapping surgery is a controversial subject in medicine today; however, few studies have examined the outcomes of this practice. The authors analyzed outcomes of patients with acutely ruptured saccular aneurysms who were treated with microsurgical clipping in a prospectively collected database from the Barrow Ruptured Aneurysm Trial. Acute and long-term outcomes for overlapping versus nonoverlapping cases were compared. METHODS During the study period, 241 patients with ruptured saccular aneurysms underwent microsurgical clipping. Patients were separated into overlapping (n = 123) and nonoverlapping (n = 118) groups based on surgical start/stop times. Outcomes at discharge and at 6 months, 1 year, 3 years, and 6 years after surgery were analyzed. RESULTS Patient variables (e.g., age, smoking status, cardiovascular history, Hunt and Hess grade, Fisher grade, and aneurysm size) were similar between the 2 groups. Aneurysm locations were similar, with the exception of the overlapping group having more posterior circulation aneurysms (18/123 [15%]) than the nonoverlapping group (8/118 [7%]) (p = 0.0495). Confirmed aneurysm obliteration at discharge was significantly higher for the overlapping group (109/119 [91.6%]) than for the nonoverlapping group (95/116 [81.9%]) (p = 0.03). Hospital length of stay, discharge location, and proportions of patients with a modified Rankin Scale (mRS) score > 2 at discharge and up to 6 years postoperatively were similar. The mean and median mRS, Glasgow Outcome Scale, Mini-Mental State Examination, National Institutes of Health Stroke Scale, and Barthel Index scores at all time points were not statistically different between the groups. CONCLUSIONS Compared with nonoverlapping surgery, overlapping surgery was not associated with worse outcomes for any variable at any time point, despite the complexity of the surgical management in this patient population. These findings should be considered during the discussion of future guidelines on the practice of overlapping surgery.

Abstract
OBJECTIVE Patients with non-traumatic rupture of an aneurysm located at the anterior communicating artery (ACoA) often experience cognitive disabilities. It is unknown whether location of aneurysm also affects the possibility for improvement in functional independence compared to patients with an aneurysmal subarachnoid hemorrhage (a-SAH) located elsewhere. The aim was to explore the association between location of aneurysm (ACoA versus other) and level of functional independence, measured by Functional Independence Measure (FIM), at discharge from rehabilitation. Additionally, age and FIM at admission were explored. METHOD Historical cohort study among 107 patients with a-SAH based on data from a clinical database and a population-based register. Data were analyzed using multivariable logistic regression. RESULTS Patients with ACoA were admitted with poorer cognitive FIM (median 6 (IQR 5-14) compared to patients with aneurysms located elsewhere (median 12 (IQR 6-23) (p = 0.0129); no difference at discharge. No association between aneurysm location and functional independence was observed. Higher age was associated with poorer outcome in bowel management OR 0.54 (95% CI 0.31-0.92), bladder management OR 0.59 (95% CI 0.35-0.98), comprehension OR 0.53 (95% CI 0.30-0.94), and memory OR 0.48 (95% CI 0.25-0.93). Overall, FIM at admission was associated with functional independence at discharge with the exception of stair walking and bladder management which did not reach statistical significance. CONCLUSION ACoA was not associated with poorer level of functional independence compared to patients with a-SAH located elsewhere. Higher age was associated with poorer outcome in continence, comprehension, and memory, whereas higher FIM was associated with better functional independence across items at discharge.

Abstract
BACKGROUND AND PURPOSE To systematically review and meta-analyse the data on impact of timing of endovascular treatment in aneurysmal subarachnoid haemorrhage (SAH) to determine if earlier treatment is associated with improved clinical outcomes and reduced case fatality. METHODS We searched MEDLINE, Cochrane database, EMBASE and Web of Science to identify studies for inclusion. The measures of effect utilised were unadjusted/adjusted ORs. Effect estimates were combined using random effects models for each outcome (poor outcome, case fatality); heterogeneity was assessed using the I2 index. Subgroup and sensitivity analyses were performed to account for heterogeneity and risk of bias. RESULTS 16 studies met the inclusion criteria. Treatment <1 day was associated with a reduced odds of poor outcome compared with treatment >1 day (OR=0.40 (95% CI 0.28 to 0.56; I2=0%)) but not when compared with treatment at 1-3 days (OR=1.16 (95% CI 0.47 to 2.90; I2=81%)). Treatment at <2 days and at <3 days were associated with similar odds of poor outcome compared with later treatment (OR=1.20 (95% CI 0.70 to 2.05; I2=73%; OR=0.71 (95% CI 0.36 to 1.37; I2=71%)). Early treatment was associated with similar odds of case fatality compared with later treatment, regardless of how early/late treatment were defined (OR=1.80 (95% CI 0.88 to 3.67; I2=34%) for treatment <1 day vs days 1-3; OR=1.71 (95% CI 0.72 to 4.03; I2=54%) for treatment <2 days vs later; OR=0.90 (95% CI 0.31 to 2.68; I2=48%) for treatment <3 days vs later). CONCLUSIONS In only 1 of the analyses was there a statistically significant result, which favoured treatment <1 day. The inconsistent results and heterogeneity within most analyses highlight the lack of evidence for best timing of endovascular treatment in SAH patients.

Abstract
Background and Purpose—
Cerebral infarction after aneurysmal subarachnoid hemorrhage is a significant cause of substantial morbidity and mortality. Because early and delayed cerebral infarction after aneurysmal subarachnoid hemorrhage may be mediated by different processes, we evaluated whether aneurysm-securing methods contributed to infarcts and whether long-term outcomes differ between early and delayed infarcts.
Methods—
A post hoc analysis of the CONSCIOUS-1 study (Clazosentan to Overcome Neurological Ischemia and Infarction Occurring After Subarachnoid Hemorrhage) was performed. Using multivariate logistic regression analysis and propensity matching, independent clinical risk factors associated with infarctions were identified, and the contribution of cerebral infarcts to long-term outcomes was evaluated.
Results—
Within the cohort of 413 subjects, early infarcts were present in 76 subjects (18%), whereas delayed infarcts occurred in 79 subjects (19%), and 36 subjects (9%) had new infarctions that were present on both early and delayed imaging. Propensity score matching revealed a significantly higher proportion of early infarcts after clipping (odds ratio, 4.62; 95% confidence interval, 1.99–11.57;
P
=0.00012). Multivariate logistic regressions identified clipping as an independent risk factor for early cerebral infarction (odds ratio, 0.26; 95% confidence interval, 0.15–0.48;
P
<0.001), and angiographic vasospasm was an independent risk factor for delayed cerebral infarction (odds ratio, 1.79; 95% confidence interval, 1.03–3.13;
P
=0.039). Early infarcts were a significant independent risk factor for poor long-term outcomes at 3 months (odds ratio, 2.34; 95% confidence interval, 1.18–4.67;
P
=0.015).
Conclusions—
Clipping is an independent risk factor for the development of early cerebral infarcts, whereas delayed cerebral infarcts are associated with angiographic vasospasm. Early cerebral infarcts are stronger predictors of worse outcome than delayed infarction.

Loss of Consciousness at Onset of Aneurysmal Subarachnoid Hemorrhage is Associated with Functional Outcomes in Good-Grade Patients. World Neurosurg 2016; 98:308-313. [PMID: 27818312 DOI: 10.1016/j.wneu.2016.10.099] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2016] [Accepted: 10/20/2016] [Indexed: 12/31/2022]
Abstract
BACKGROUND Transient loss of consciousness (LOC) is one of the most common presentations of aneurysmal subarachnoid hemorrhage (SAH) and may be an indicator of early brain injury. In this study, we examined the association of LOC and functional outcomes in patients with good-grade SAH. METHODS We searched the Subarachnoid Hemorrhage International Trialists Repository for patients who presented with LOC at ictus of SAH. A propensity score analysis was performed on good-grade patients (defined as World Federation of Neurosurgical Societies grade 1-3) to balance selected covariates between those with and without LOC. The primary outcome was Glasgow Outcome Score (GOS) at 3 months (with poor outcome defined as a GOS of 1-3). Secondary outcomes were delayed cerebral ischemia (DCI), rebleed, length of hospital stay, and time to death. RESULTS A propensity score-matching algorithm identified 336 patients (168 with and 168 without LOC at ictus). The proportion of patients with poor functional outcome at 3 months was significantly higher in the cohort with LOC at ictus compared with the matched cohort without LOC at ictus (30% vs. 19%; P = 0.02). There was a nonsignificant trend toward greater mortality in the patients with LOC at ictus (19% vs. 13%; P = 0.14). There were no significant differences in the secondary outcomes between the 2 cohorts. CONCLUSIONS LOC at ictus of SAH is associated with a higher rate of unfavorable functional outcomes but not of mortality, DCI, or rebleed in patients with good-grade SAH. Future studies should further investigate the putative mechanisms through which LOC mediates early brain injury in SAH.
