Background: There are many scores and markers that predict poor outcome in patients with subarachnoid hemorrhage (SAH). However, parameters that can predict outcomes in patients with SAH with high specificity and sensitivity, which can be identified in the early postictal state and utilized as a clinical marker of early brain injury (EBI) have not been identified so far. Methods: Thirty-nine patients with SAH due to a saccular intracranial aneurysm rupture were reviewed. We retrospectively analyzed the relationships between patients’ baseline characteristics and patients’ outcomes to identify parameters that could predict patient outcomes in the early postictal state. Results: In the univariate analysis, older age (>65), loss of consciousness (LOC) at ictus, poor initial World Federation of Neurosurgical Societies (WFNS) grade (3–5), and delayed cerebral ischemia (DCI) were associated with poor outcome (GOS 1–3). Statistical analyses revealed that combined LOC at ictus and/or poor initial WFNS grade (3–5) was a more powerful surrogate marker of outcome (OR 15.2 [95% CI 3.1–75.5]) than either LOC at ictus or the poor initial WFNS grade (3–5) alone. Multivariate logistic regression analyses revealed that older age, combined LOC at ictus and/or poor initial WFNS grade, and DCI were independently associated with poor outcome. Conclusion: Combined LOC at ictus and/or poor initial WFNS grade (3–5) reflects the impact of EBI and was a useful surrogate marker of poor prognosis in SAH patients, independent of patients’ age and state of DCI.

Background: Previous studies have demonstrated the importance keeping thrombectomy procedure times ≤60 min., termed the ‘golden hour’. In the current study, we further investigate the significance of the ‘golden hour’ and the impact of procedural timing on clinical outcomes after mechanical thrombectomy. Methods: We performed an analysis of 319 consecutive mechanical thrombectomy patients at a single Comprehensive Stroke Center from April 2012 through February 2019. Bivariate analyses compared patients grouped according to procedure time ≤60 min. or >60 min. and time of stroke onset-to-endovascular therapy (OTE) ≤6 hours or >6 hours. Logistic regression was used to determine independent predictors of poor outcome at 90-days defined by modified Rankin Scale (mRS) scores of 3-6. Results: A procedure time ≤60 min. was associated with increased revascularization rates (88% vs. 67%; p<0.001) and a greater percentage of good outcomes at 90-days (47% vs. 31%; p=0.003). Multivariable logistic regression revealed that greater age (OR 1.03, 95% CI 1.004-1.051; p=0.023), higher admission NIHSS score (OR 1.10, 95% CI 1.038-1.159; p=0.001), and history of diabetes mellitus (OR 1.94, 95% CI 1.049-3.580; p=0.035) were independently associated with a greater odds of poor outcome. Modified TICI scale scores of 2C (OR 0.12, 95% CI 0.047-0.313; p<0.001) and 3 (OR 0.19, 95% CI 0.079-0.445; p<0.001) were associated with a reduced odds of poor outcome. Although not statistically significant on univariate analysis, OTE ≤6 hrs. was independently associated with a reduced odds of poor outcome (OR 0.41, 95% CI 0.212-0.809; p=0.010) in the final multivariate model (AUC 0.800). Procedure time ≤60 min. did not have a significant independent association with clinical outcome on multivariate analysis (p=0.095). Conclusions: Thrombectomy procedure times beyond 60 min. are associated with lower overall revascularization rates and worse 90 day functional outcomes when compared to faster thrombectomy procedures. However, thrombectomy procedure time was not predictive of outcome on multivariable logistic regression analysis. Our study emphasizes the significance of achieving revascularization despite the requisite procedure time.

During embolectomy for acute stroke, transfemoral access to occluded vessel may be technically difficult. We aim to study the impact of difficult catheter access to target artery. Methods: Single center review of anterior circulation stroke patients enrolled in prospective trials/registries (MR Rescue, MERCI, DEFUSE) requiring recording of time from groin puncture to first device deployment(Tdep). Patients were divided according to Tdep quartiles (Q): patients in Q4 were considered as difficult access. We recorded recanalization (TICI≥2a), complete recanalization (TICI≥2b), infarct volume(24h DWI), day 5 NIHSS, and favorable outcome (3 months mRS≤2). Results: We included 196 patients, mean age 66±14, median NIHSS 16(IQR:12-21). Overall outcomes were: median Tdep 52 min (36-77), recanalization 89.1%, complete recanalization 59.4%, favorable outcome 43.8%. We observed a positive correlation between Tdep and day 5 NIHSS (r=0.27; p=0.01) or 3 months mRS (r=0.26; p<0.01). Patients with difficult access (Q4: Tdep>77 min) had similar baseline NIHSS (16 Vs 17 p=0.58), time from symptom to procedure start (433 Vs 371min; p=0.28) and occlusion location (ICA/M1/M2: 46.7/42.2/11.1% Vs 39.1/54.3/6.5%; p=0.31). However, patients in Q4 had: longer IA procedures (153 vs 112 min;p<0.01), lower complete recanalization (41% Vs 66%;p<0.01), larger infarcts (87 Vs 53cc; p<0.01), higher day 5 NIHSS (15 Vs 9;p<0.01), and less favorable outcome (29.2% Vs 49%; p=0.02). After adjusting by age and time to reperfusion, a regression model identified admission NIHSS (OR% 1.12: 95%CI 1.02-1.21; p<0.01), age (OR% 1.03: 95%CI 1.01-1.06; p=0.01) and Tdep (OR% 1.02 95%CI 1.01-1.03; p=0.01) as independent predictors of poor outcome. In univariate analysis age>69, male gender and left hemisphere stroke were associated with difficult access. The combined presence of the 3 factors increased by 3.5 fold the likelihood of difficult access (OR:3.55 95%CI 1.5-8.6: p<0.01) Conclusion: Delayed device access to target occluded artery independently predicts poor outcome. Identification of difficult access using clinical scores or imaging may lead to alternative strategies; brachial, radial or cervical approaches that could result in shortened procedural times and improved outcomes

The Impact

Background: Fever has been associated with worse clinical outcomes in aneurysmal subarachnoid hemorrhage (aSAH). However, the impact of the cause, severity, and duration of fever is not clear. We conducted this study to evaluate the impact of fever and subfebrile load and fever characteristics on functional outcome. Methods: We collected detailed information on fever onset, cause, severity, and duration during the ICU stay in a cohort of 586 consecutive patients with aSAH. Fever was defined as core body temperature ≥ 38.3°C. Subfebrile measurements were those between 37 and 38.2°C. Febrile and subfrebile loads were defined as number of hours with fever or subfebrile measurements. Poor outcome was defined as modified Rankin score (mRS) > 2. Univariate and multivariate logistic regression models were developed to define predictors of outcome using various categorizations of fever cause, severity, and duration. Results: 532/586 patients (90.9%) had fever for a mean of 2.1±3.0 days. Fever started within 24 hours in 69 (11.8%) and within 72 hours in 110 (18.8%). Poor outcome occurred in 175 patients (29.9%). On univariate analysis, days of fever, febrile load, fever onset within 24 hours, and fever onset within 72 hours were associated with poor outcome (all p<0.001), but subfebrile load was not (p=0.58). On multivariate model constructed with all variables associated with outcome on univariate analyses (including age, WFNS grade, modified Fisher grade) days of fever remained independently associated with poor outcome (OR 1.14 of poor outcome per day of fever, 95% CI 1.06-1.22; p=0.0006) displacing all other fever measures from the final model. Conclusions: The great majority of patients with aSAH are febrile during their ICU stay. Early onset of fever, number of hours with fever, and especially days of fever are associated with poor functional outcome. Conversely, the number of hours with elevated but subfebrile temperature does not influence clinical outcome. These data suggest that prolonged fever should be avoided, but subfebrile temperatures do not justify intervention.

e21007 Background: There is a lack of data to guide the management of resectable bronchopulmonary carcinoid tumors (BCTs). Methods: The NCDB database was retrospectively reviewed to analyze the roles of surgery, chemotherapy and radiation. Patients with a diagnosis of clinically staged T1-2/N0-1 typical carcinoid (TC) and atypical carcinoid (AC) between 2004-2012 were included. Kaplan-Meier methods and multivariable analysis were performed. Results: A total of 2148 patients (TC 1874 & AC 274; T1/1648 & T2/500) were identified. The median age was 59 (range 18-89). There was a female (69.7%) and right lung (56.9%) predominance. Fifty-three patients received pneumonectomy, 68 chemotherapy, and 84 radiation therapy. The impact of age, histology (TC vs. AC), medical comorbidities (Charlson/Deyo score 0 vs. ≥1) and type of surgery [sublobar resection (SR) vs. lobectomy vs. lobectomy with mediastinal lymph node dissection (L/MLND)] were subsequently examined. AC, older age, and comorbidities were associated with shorter overall survival (OS) by both univariate and multivariable analysis. Patients who underwent lobectomy had longer OS (119 months) than those with SR (109 months) or L/MLND (115 months). However, this association was not significant by multivariable analysis with age incorporated as either a categorical ( < 60 vs. ≥60) or a continuous variable (Table). In the subgroup analysis of patients with T1, T2, TC and AC respectively, type of surgical resection was not significantly associated with OS by multivariable analysis. Conclusions: Patients with resectable BCTs have excellent OS. Atypical histology, older age, and comorbidities predicted inferior OS. There were insufficient data to support the use of perioperative chemotherapy or radiation therapy. Lobectomy was associated with prolonged OS by univariate analysis but this was not significant in the multivariable model, suggesting that SR is a reasonable approach for patients who cannot tolerate lobectomy. MLND did not seem to provide additional survival benefits. [Table: see text]

2063 Background: Gangliogliomas (GG) represent less than 1% of primary brain tumors in adults. Little is known regarding prognostic features, clinical characteristics or the impact of treatment on patient (pt) outcomes. Methods: In this IRB approved retrospective study, our neuro-oncology longitudinal database was screened for pts with GG from 1992-2012. 67 adult pts (age>18) were identified. Results: 60 pts presented with low grade GG and 7 with anaplastic GG. The median age at diagnosis was 27 years (18-59). 22 pts developed recurrent disease (18 low grade and 4 high grade) with a median time to recurrence of 87 weeks from surgery. 7 of the pts with low grade GG had malignant transformation to a malignant tumor (anaplastic GG or GBM). 22 pts received radiation therapy, 16 at diagnosis. 14 pts received chemotherapy at recurrence. Pts with incomplete resections or higher grade tumors were more likely to receive chemotherapy or radiation. The median overall survival (OS) time for these pts was not reached with a median follow-up time of 4.6 years. The 2-, 5- and 10-year OS were 98%, 87%, and 76%. Factors on univariate analysis that were significantly associated with OS were KPS at presentation (HR 10.1; 95% CI 2.6, 39.1; p = 0.0008), extent of resection (EOR) (biopsy vs gross total; HR 12.1; 95% CI 2.3, 63.6; p = 0.003), histologic grade (Grade 1-2 vs Grade 3-4; HR 0.06; 95% CI 0.01, 0.3; p = 0.0002), and seizure control following surgery (Engel I vs Engel 2-3; HR 0.1; 95% CI 0.01, 0.9; p = 0.02). Factors on univariate analysis that were significantly associated with progression free survival (PFS) were EOR (biopsy vs gross total; HR 4.0; 95% CI 1.4, 11.9; p = 0.01) and histologic grade (Grade 1-2 vs .Grade 3-4; HR 0.3; 95% CI 0.08, 0.8; p = 0.02). On multivariate analysis, EOR is most significant for PFS (p = 0.01), while tumor grade is most significant for OS (p = 0.004). Conclusions: While GG have an excellent prognosis, malignant histological grade, diagnosis with a biopsy only, poor initial KPS, and presence of seizures following surgery could indicate a worse prognosis. The role of chemotherapy and radiation therapy for incompletely resected or inaccessible low grade GG is unclear.

OBJECTIVE Delayed cerebral ischemia (DCI) has a major impact on the outcome of patients suffering from aneurysmal subarachnoid hemorrhage (SAH). The aim of this study was to assess the influence of an additional intracerebral hematoma (ICH) on the occurrence of DCI. METHODS The authors conducted a single-center retrospective analysis of cases of SAH involving patients treated between 2006 and 2011. Patients who died or were transferred to another institution within 10 days after SAH without the occurrence of DCI were excluded from the analysis. RESULTS Additional ICH was present in 123 (24.4%) of 504 included patients (66.7% female). ICH was classified as frontal in 72 patients, temporal in 24, and perisylvian in 27. DCI occurred in 183 patients (36.3%). A total of 59 (32.2%) of these 183 patients presented with additional ICH, compared with 64 (19.9%) of the 321 without DCI (p = 0.002). In addition, DCI was detected significantly more frequently in patients with higher World Federation of Neurosurgical Societies (WFNS) grades. The authors compared the original and modified Fisher Scales with respect to the occurrence of DCI. The modified Fisher Scale (mFS) was superior to the original Fisher Scale (oFS) in predicting DCI. Furthermore, they suggest a new classification based on the mFS, which demonstrates the impact of additional ICH on the occurrence of DCI. After the different scales were corrected for age, sex, WFNS score, and aneurysm site, the oFS no longer was predictive for the occurrence of DCI, while the new scale demonstrated a superior capacity for prediction as compared with the mFS. CONCLUSIONS Additional ICH was associated with an increased risk of DCI in this study. Furthermore, adding the presence or absence of ICH to the mFS improved the identification of patients at the highest risk for the development of DCI. Thus, a simple adjustment of the mFS might help to identify patients at high risk for DCI.

Abstract INTRODUCTION Changes in serum sodium levels are common following aneurysmal subarachnoid hemorrhage (aSAH), and may be linked to increased morbidity. In this exploratory analysis we assessed whether fluctuations in serum sodium levels after aSAH have an association with clinical outcomes and/or delayed cerebral ischemia (DCI). METHODS We performed a retrospective analysis of data from CONSCIOUS-1 (n = 413), a randomized controlled trial of clazosentan treatment in patients with aSAH. Patient serum sodium levels were checked daily during the hospital stay up to day 14. Mean-per-day fluctuations in serum sodium were calculated by summing the absolute deviation of serum sodium at day 2–14 from day 1 base-line divided by the total number of days with lab values. Logistic regression and LOWESS smoothing curves were used to determine association between serum sodium deviation and poor outcome at 3 months (defined as modified Rankin Scale, mRS> 2) or DCI. RESULTS >Mean-per-day deviation of serum sodium from baseline was associated with poor outcome on univariate analysis (P = 0.028), and maintained statistical significance after correcting for age and World Federation of Neurological Surgeons (WFNS) grade (P = 0.044). A LOWESS smoothing curve showed an increased risk of DCI for patients with greater deviations from their baseline sodium values. Multivariate regression, including WFNS and Fisher Scale grades, demonstrated absolute variation in sodium values to be associated with DCI (P = 0.045). CONCLUSION In this study, greater deviations in serum sodium values independently predicted poor outcome and the development of DCI.

Introduction: Sex is a known predictor of outcome after acute ischemic stroke. However, the effect of sex on outcome after subarachnoid hemorrhage (SAH) is not well studied. Methods: Five studies from the SAH International Trialists repository were included (4 randomized trials and 1 prospective study). Patients were divided into groups based on sex. The primary outcome was favorable outcome which was defined as Glasgow Outcome Score (GOS) of 4 or 5 and the secondary outcome was delayed cerebral ischemia (DCI). Binary logistic regression was done to assess the association between sex and outcomes. Results: A total of 8015 patients (2186 males and 5829 females) were included. Female patients were older (mean age 53 vs 50 years, p<0.001) and had more severe neurological deficit on presentation (median World Federation of Neurosurgical Societies [WFNS] grade 2 vs.1; p<0.001). Favorable outcome was achieved less frequently in females in univariate analysis (51% vs. 62%; p<0.001). In a multivariable model adjusted for age, WFNS, Fisher score, aneurysm location, and aneurysm size, female was associated with lower odds of favorable outcome (OR= 0.82; 95% CI:0.73-0.92). DCI occurred more frequently in females (25% vs. 18%; p<0.001). In addition, women had higher risk of DCI after adjusting for potential confounders (women vs. men, OR 1.43; 95%CI: 1.26-1.63). We did not find an interaction between age and sex for both favorable outcome and clinical vasospasm. Conclusion: Female patients had worse functional outcome and higher risk of DCI after subarachnoid hemorrhage when compared to men.

Object After aneurysmal subarachnoid hemorrhage (SAH), conflicting results concerning an association between the APOE genotype and impaired outcome have been reported. The authors tested prospectively whether APOE ε2 or ε4 allele–containing genotypes (ε2+ and ε4+) affect outcome after SAH. Methods Previous disease histories and clinical and radiological variables were recorded for 105 patients who were admitted within 48 hours after SAH. Fifteen patients (14%) had the ε2+ genotype and 31 (17%) had ε4+ genotypes. Factors predicting poor outcome according to the Glasgow Outcome Scale and cerebral infarction visible on CT scans obtained at 3 months after SAH were tested with multiple logistic regression analyses. Results Apolipoprotein E ε2 or ε4–containing genotypes were not associated with outcome, occurrence of cerebral infarction, or with any of their predictors, either in univariate or multivariate analysis. Poor outcome was predicted independently by the occurrence of intraventricular bleeding and intracerebral hematoma as well as by elevated levels of both plasma glucose and D-dimer, and delayed cerebral ischemia (p < 0.05 for each factor), and in univariate analysis only by clinical condition on admission and patient age. Cerebral infarction was predicted independently according to clinical condition on admission (p < 0.05), amount of subarachnoid blood (p < 0.01), duration of intraoperative parent artery clipping (p < 0.01), and body mass index (p < 0.05). In the univariate analysis only cerebral infarction was also predicted by patient age, intracerebral hematoma, and delayed cerebral ischemia. Conclusions Severity of bleeding for the most part predicts outcome after SAH; APOE polymorphisms seem to have no prognostic value for outcome after SAH. This result was in accordance with the findings from the largest ischemic stroke studies.

Abstract Background The role of reactive thrombocytosis in non-aneurysmal subarachnoid hemorrhage (NA-SAH) is largely unexplored to date. Therefore, the impact of a quantitative thrombocyte dynamic in patients with NA-SAH and its clinical relevance were analyzed in the present study. Methods In this retrospective analysis, 113 patients with nontraumatic and NA-SAH treated between 2003 and 2015 at our institution were included. World Federation of Neurosurgical Societies admission status, cerebral vasospasm, delayed infarction, hydrocephalus, need for ventriculoperitoneal (VP) shunt, and Fisher grade were analyzed for their association with reactive thrombocytosis. Results Reactive thrombocytosis was not associated with hydrocephalus (p ≥ 0.05), need for VP shunt implantation (p ≥ 0.05), cerebral vasospasm (p ≥ 0.05), or delayed cerebral ischemia (p ≥ 0.05). Conclusion Our study is the first to investigate the role of thrombocyte dynamics, reactive thrombocytosis, and the clinical course of NA-SAH patients. Our analysis showed no significant impact of thrombocyte count on NA-SAH sequelae.
