Background: Anemia following aneurysmal subarachnoid hemorrhage (aSAH) has been associated with poor outcome, but complications from transfusion have limited aggressive management of anemic patients. This study examined the relationship between hemoglobin levels, transfusion and outcome following aSAH. Methods: We performed a post-hoc analysis of the CONSCIOUS-1 trial. Poor outcome was defined as a 3-month modified Rankin Scale > 2. Minimum hemoglobin levels were evaluated as predictors of outcome using logistic regression analysis, ROC curve analysis, and LOWESS curves. Propensity score matching was used to assess the effect of transfusion on poor outcome in patients with minimum hemoglobin levels between 70-90 and 80-100 g/L. Results: Lower minimum hemoglobin levels were associated with poor outcome on both univariate (p<0.001) and multivariate (p=0.012) analysis. Area under the ROC curve for minimum hemoglobin was 0.673. Youden index analysis found a minimum hemoglobin threshold of 91.5 g/L maximally predictive for good functional outcome. Propensity score matching showed a trend towards poor outcome in transfused patients with minimum hemoglobin levels between 70-90 and 80-100 g/L (p=0.052 and 0.09). Conclusions: This work suggests that decreasing hemoglobin is an independent predictor of poor outcome following aSAH. However, there was a trend towards poor outcome in transfused patients. The optimal transfusion threshold should be evaluated by prospective trials.

BACKGROUND: Quantitative estimation of the hemorrhage volume associated with aneurysm rupture is a new tool of assessing prognosis. OBJECTIVE: To determine the prognostic value of the quantitative estimation of the amount of bleeding after aneurysmal subarachnoid hemorrhage, as well the relative importance of this factor related to other prognostic indicators, and to establish a possible cut-off value of volume of bleeding related to poor outcome. METHODS: A prospective cohort of 206 patients consecutively admitted with the diagnosis of aneurysmal subarachnoid hemorrhage to Hospital 12 de Octubre were included in the study. Subarachnoid, intraventricular, intracerebral, and total bleeding volumes were calculated using analytic software. For assessing factors related to prognosis, univariate and multivariate analysis (logistic regression) were performed. The relative importance of factors in determining prognosis was established by calculating their proportion of explained variation. Maximum Youden index was calculated to determine the optimal cut point for subarachnoid and total bleeding volume. RESULTS: Variables independently related to prognosis were clinical grade at admission, age, and the different bleeding volumes. The proportion of variance explained is higher for subarachnoid bleeding. The optimal cut point related to poor prognosis is a volume of 20 mL both for subarachnoid and total bleeding. CONCLUSION: Volumetric measurement of subarachnoid or total bleeding volume are both independent prognostic factors in patients with aneurysmal subarachnoid hemorrhage. A volume of more than 20 mL of blood in the initial noncontrast computed tomography is related to a clear increase in poor outcome risk.

Abstract Objective: Chronic obstructive pulmonary disease (COPD) has been associated with several complications and mortality in acutely ill patients. For patients with aneurysmal subarachnoid hemorrhage (aSAH), the association between COPD and clinical outcomes remains unclear. Methods: In this retrospective cohort study, we analyzed consecutive aSAH patients admitted to the West China Hospital between 2009 and 2019. Propensity score matching was performed to obtain the adjusted odds ratios (ORs) with 95% CI. The primary outcome was in hospital mortality.Results: Using a ten-year clinical database from a large university medical center, 5643 patients with aSAH were identified, of whom 377 (7.9%) also had COPD. After matching, 289 patients were included in COPD group and 1156 in non-COPD groups. COPD was associated with increased in-hospital mortality (OR 1.63, 95% CI 1.02-2.62) and poor functional outcome at discharge (OR 1.37, 95% CI 1.04-1.80). Similarly, patients with COPD had significantly longer length of hospital stay, higher odds of seizure (OR 2.05, 95% CI 1.04-4.04), pneumonia (OR 3.10, 95% CI 2.38-4.04), intracranial infection (OR 1.62, 95% CI 1.14-2.29), urinary tract infection (OR 1.59, 95% CI 1.16-2.20) and bloodstream infection(OR 3.27, 95% CI 1.74-6.15). Conclusions: Among aSAH patients, COPD is associated with increased mortality. COPD represents a significant risk factor for pneumonia and seizure.

OBJECTIVEDelayed cerebral ischemia (DCI) and aneurysm rebleeding contribute to morbidity and mortality in aneurysmal subarachnoid hemorrhage (aSAH); however, the relationship between their impacts on overall functional outcome is incompletely understood.METHODSThe authors conducted a cohort study of all aSAH during the study period from 2001 to 2016. Primary end points were overall functional outcome and ischemic aSAH sequelae, defined as delayed cerebral ischemia (DCI), DCI with infarction, symptomatic vasospasm (SV), and global cerebral edema (GCE). Outcomes were compared between the rebleed and nonrebleed cohorts overall and after propensity-score matching (PSM) for risk factors and treatment modality. Univariate and multivariate ordered logistic regression analyses for functional outcomes were performed in the PSM cohort to identify predictors of poor outcome.RESULTSFour hundred fifty-five aSAH cases admitted within 24 hours of aneurysm rupture were included, of which 411 (90%) experienced initial aneurysm ruptures only, while 44 (10%) had clinically confirmed rebleeding. In the overall cohort, rebleeding was associated with significantly worse functional outcome, longer intensive care unit length of stay (LOS), and GCE (all p < 0.01); treatment modality, overall LOS, DCI, DCI with infarction, and SV were nonsignificant. In the PSM analysis of 43 matched rebleed and 43 matched nonrebleed cases, only poor functional outcome and GCE remained significantly associated with rebleeding (p < 0.01 and p = 0.02, respectively). Multivariate regression identified that both rebleeding (HR 21.5, p < 0.01) and DCI (HR 10.1, p = 0.01) independently predicted poor functional outcome.CONCLUSIONSRebleeding and DCI after aSAH are highly morbid and potentially deadly events after aSAH, which appear to have independent negative impacts on overall functional outcome. Early rebleeding did not significantly affect the risk of delayed ischemic complications.

Background and Purpose: Systemic inflammation is recognized as a hallmark of stroke. We aimed to evaluate the prognostic value of various inflammatory factors using blood at admission in patients with aneurysmal subarachnoid hemorrhage. Methods: In a multicenter observational study of patients with aneurysmal subarachnoid hemorrhage, the counts of neutrophil, platelet, and lymphocyte were collected on admission. Patients were stratified based on neutrophil counts with propensity score matching to minimize confounding. We calculated the adjusted odds ratios with 95% CIs for the primary outcome of in-hospital mortality and hospital-acquired infections. Results: A total of 6041 patients were included in this study and 344(5.7%) of them died in hospital. Propensity score matching analyses indicated that compared with the lower neutrophil counts, higher neutrophil counts were associated with increased risk of in-hospital mortality (odds ratio, 1.53 [95% CI, 1.14–2.06]), hospital-acquired infections (odds ratio, 1.61 [95% CI, 1.38–1.79]), and delayed neurological ischemic deficits (odds ratio, 1.52 [95% CI, 1.09–1.97]). Moreover, out of all the inflammatory factors studied, neutrophil counts demonstrated the highest correlation with in-hospital mortality and hospital-acquired infections. Conclusions: Among patients with aneurysmal subarachnoid hemorrhage, high neutrophil counts at admission were associated with increased mortality and hospital-acquired infections. The neutrophil count is a simple, useful marker with prognostic value in patients with aneurysmal subarachnoid hemorrhage.

OBJECTIVETimely aneurysm occlusion and neurointensive care treatment are key principles in the management of aneurysmal subarachnoid hemorrhage (aSAH) to prevent secondary brain injury. Patients with early (EHA) and delayed hospital admission (DHA) were compared in terms of clinical presentation, treatment strategies, aSAH-related complications, and outcome.METHODSIn this retrospective study, consecutive aSAH patients were treated at a single neurovascular center between 2009 and 2019. Propensity score matching was performed to account for divergent baseline characteristics.RESULTSAmong 509 included patients, 55 were admitted more than 48 hours after ictus (DHA group). DHA patients were significantly younger (52 ± 11 vs 56 ± 14 years, p = 0.03) and had lower World Federation of Neurosurgical Societies scores (p < 0.01) than EHA patients. In 54.5% of the cases, DHA patients presented with neurological deterioration or aggravated symptoms. Propensity score matching revealed a higher vasospastic infarction rate in the DHA group (41.5%) than in the EHA group (22.6%) (p = 0.04). A similar portion of patients in both groups achieved favorable outcome at midterm follow-up (77.3% vs 73.6%, p = 0.87). DHA patients (62.3%) received conventional coiling more often than EHA patients (41.5%) (p = 0.03).CONCLUSIONSDHA patients are at an increased risk of cerebral infarction. Nevertheless, state-of-the-art neurointensive care treatment can result in a good clinical outcome.

Object At present, the administration of prophylactic antiepileptic medication following aneurysmal subarachnoid hemorrhage (SAH) is controversial, and the practice is heterogeneous. Here, the authors sought to inform clinical decision making by identifying factors associated with the occurrence of seizures following aneurysm rupture. Methods Exploratory analysis was performed on 413 patients enrolled in CONSCIOUS-1 (Clazosentan to Overcome Neurological Ischemia and Infarction Occurring after Subarachnoid Hemorrhage), a prospective randomized trial of clazosentan for the prevention of angiographic vasospasm. The association among clinical, laboratory, and radiographic covariates and the occurrence of seizures following SAH were determined. Covariates with a significance level of p < 0.20 on univariate analysis were entered into a multivariate logistic regression model. Receiver operating characteristic (ROC) curve analysis was used to define optimal predictive thresholds. Results Of the 413 patients enrolled in the study, 57 (13.8%) had at least 1 seizure following SAH. On univariate analysis, a World Federation of Neurosurgical Societies grade of IV–V, a greater subarachnoid clot burden, and the presence of midline shift and subdural hematomas were associated with seizure activity. On multivariate analysis, only a subarachnoid clot burden (OR 2.76, 95% CI 1.39–5.49) and subdural hematoma (OR 5.67, 95% CI 1.56–20.57) were associated with seizures following SAH. Using ROC curve analysis, the optimal predictive cutoff for subarachnoid clot burden was determined to be 21 (of a possible 30) on the Hijdra scale (area under the curve 0.63). Conclusions A greater subarachnoid clot burden and subdural hematoma are associated with the occurrence of seizures after aneurysm rupture. These findings may help to identify patients at greatest risk for seizures and guide informed decisions regarding the prescription of prophylactic anticonvulsive therapy.

Objective: With the aging of the world population, the number of elderly patients suffering from aneurysmal subarachnoid hemorrhage (aSAH) is gradually growing. We aim to investigate the potential association between plasma ALT level and clinical complications of elderly aSAH patients, and explore its predictive value for clinical outcomes of elderly aSAH patients. Methods: Between January 2013 and March 2018, 152 elderly aSAH patients were analyzed in this study. Clinical information, imaging findings and laboratory data were reviewed. According to the Glasgow Outcome Scale (GOS), clinical outcomes at 3 months were classified into favorable outcomes (GOS 4-5) and poor outcomes (GOS 1-3). Logistic regression analysis was used to assess the indicators associated with poor outcomes, and receiver curves (ROC) and corresponding area under the curve (AUC) were used to detect the accuracy of the indicator. Results: A total of 48 (31.6 %) elderly patients with aSAH had poor outcome at 3 months. In addition to ICH, IVH, Hunt-Hess 4 or 5 Grade and Modified Fisher 3 or 4 Grade, plasma ALT level was also strongly associated with poor outcome of elderly aSAH patients. After adjusting for other covariates, plasma ALT level remained independently associated with pulmonary infection (OR 1.05; 95% CI 1.00–1.09; P = 0.018), cardiac complications (OR 1.05; 95% CI 1.01–1.08; P = 0.014) and urinary infection (OR 1.04; 95% CI 1.00–1.08; P = 0.032). Besides, plasma ALT level had a predictive ability in the occurrence of systemic complications (AUC 0.676; 95% CI: 0.586– 0.766; P<0.001) and poor outcome (AUC 0.689; 95% CI: 0.605–0.773; P<0.001) in elderly aSAH patients. Conclusion: Plasma ALT level of elderly patients with aSAH was significantly associated with systemic complications, and had additional clinical value in predicting outcomes. Given that plasma ALT levels on admission could help to identify high-risk elderly patients with aSAH, these findings are of clinical relevance.

Background: Several clinical studies have indicated the efficacy of cilostazol, a selective inhibitor of phosphodiesterase 3, in preventing cerebral vasospasm after aneurysmal subarachnoid hemorrhage (SAH). They were not double-blinded trial resulting in disunited results on assessment of end points among the studies. The randomized, double-blind, placebo-controlled study was performed to assess the effectiveness of cilostazol on cerebral vasospasm. Methods: Patients with aneurysmal SAH admitted within 24 h after the ictus who met the following criteria were enrolled in this study: SAH on CT scan was diffuse thick, diffuse thin, or local thick, Hunt and Hess score was less than 4, administration of cilostazol or placebo could be started within 48 h of SAH. Patients were randomly allocated to placebo or cilostazol after repair of a ruptured saccular aneurysm by aneurysmal neck clipping or endovascular coiling, and the administration of cilostazol or placebo was continued up to 14 days after initiation of treatment. The primary end point was the occurrence of symptomatic vasospasm (sVS), and secondary end points were angiographic vasospasm (aVS) evaluated on digital subtraction angiography, vasospasm-related new cerebral infarction evaluated on CT scan or MRI, and clinical outcome at 3 months of SAH as assessed by Glasgow Outcome Scale, in which poor outcome was defined as severe disability, vegetative state, and death. All end points were evaluated with blinded assessment. Results: One hundred forty eight patients were randomly allocated to the cilostazol group (n = 74) or the control group (n = 74). The occurrence of sVS was significantly lower in the cilostazol group than in the control group (10.8 vs. 24.3%, p = 0.031), and multiple logistic analysis showed that cilostazol use was an independent factor reducing sVS (OR 0.293, 95% CI 0.099-0.568, p = 0.027). The incidence of aVS and vasospasm-related cerebral infarction were not significantly different between the groups. Poor outcome was significantly lower in the cilostazol group than in the control group (5.4 vs. 17.6%, p = 0.011), and multiple logistic analyses demonstrated that cilostazol use was an independent factor that reduced the incidence of poor outcome (OR 0.221, 95% CI 0.054-0.903, p = 0.035). Severe adverse events due to cilostazol administration did not occur during the study period. Conclusions: Cilostazol administration is effective in preventing sVS and improving outcomes without severe adverse events. A larger-scale study including more cases was necessary to confirm this efficacy of cilostazol.

✓ Plasma glucose levels were studied in 616 patients admitted within 72 hours after subarachnoid hemorrhage (SAH). Glucose levels measured at admission showed a statistically significant association with Glasgow Coma Scale scores, Botterell grade, deposition of blood on computerized tomography (CT) scans, and level of consciousness at admission. Elevated glucose levels at admission predicted poor outcome. A good recovery, as assessed by the Glasgow Outcome Scale at 3 months, occurred in 70.2% of patients with normal glucose levels (≤ 120 mg/dl) and in 53.7% of patients with hyperglycemia (> 120 mg/dl) (p = 0.002). The death rates for these two groups were 6.7% and 19.9%, respectively (p = 0.001). The association was still maintained after adjusting for age (> or ≤ 50 years) and thickness of clot on CT scans (thin or thick) in the subset of patients who were alert/drowsy at admission. Increased mean glucose levels between Days 3 and 7 also predicted a worse outcome; good recovery was observed in 132 (73.7%) of 179 patients who had normal mean glucose levels (≤ 120 mg/dl) and 160 (49.7%) of 322 who had elevated mean glucose levels (> 120 mg/dl) (p < 0.0001). Death occurred in 6.7% and 20.8% of the two groups, respectively (p < 0.0001). It is concluded that admission plasma glucose levels can serve as an objective prognostic indicator after SAH. Elevated glucose levels during the 1st week after SAH also predict a poor outcome. However, a causal link between hyperglycemia and outcome after delayed cerebral ischemia, although suggested by experimental data, cannot be established on the basis of this study.
