Abstract
BACKGROUND Demographic changes are leading to an aging society with a growing number of patients relying on anticoagulation, and vitamin K antagonists (VKA) are still widely used. As mortality and functional outcomes are worse in case of VKA-associated hemorrhagic stroke, phenprocoumon treatment seems to be a negative prognostic factor in case of subarachnoid hemorrhage (SAH). The purpose of this study was to analyze whether phenprocoumon treatment does worsen the outcome after non-traumatic SAH. METHODS All patients treated for non-traumatic SAH between January 2007 and December 2016 in our institution were retrospectively analyzed. After exclusion of patients with anticoagulant or antiplatelet treatment other than phenprocoumon, we analyzed 1040 patients. Thirty-three patients (3%) of those were treated with continuous phenprocoumon. In total, 132 out of all 1007 patients without anticoagulant treatment of the remaining patients were matched as control group (ratio = 1:4). RESULTS Patients with phenprocoumon treatment were significantly older (66.5 years vs. 53.9 years; p < .0001), and admission status was significantly more often poor (66.7% vs. 41.8%, p = .007) compared to all patients without anticoagulant treatment. Further, bleeding pattern and rates of early hydrocephalus did not differ. Matched-pair analysis revealed a significant higher rate of angio-negative SAH in the study group (p = .001). Overall rates of hemorrhagic or thromboembolic complications did not differ (21.4% vs. 18.8%; NS) but were more often fatal, and 30-day mortality rate was significantly higher in the phenprocoumon group than in patients of the matched-pair control group (33% vs. 24%; p < .001). 30% of the phenprocoumon group and 37% of the matched-pair control group reached favorable outcome. However, poor outcome was strong associated with the reason for phenprocoumon treatment. CONCLUSION Patients with phenprocoumon treatment at the time of SAH are significantly older, admission status is worse, and 30-day mortality rates are significantly higher compared to patients without anticoagulant treatment. However, outcome at 6 months did not differ to the matched-pair control group but seems to be strongly associated with the underlying cardiovascular disease. Treatment of these patients is challenging and should be performed on an interdisciplinary base in each individual case. Careful decision-making regarding discontinuation and bridging of anticoagulation and close observation is mandatory.

Abstract
BACKGROUND To provide updated information on seizure events and patterns in patients with angiogram-negative subarachnoid hemorrhage based on the initial hemorrhage patterns: perimesencephalic subarachnoid hemorrhage (PMH) vs non-PMH. METHODS A review of online database literature from January 1990 to November 2017 was systematically performed. In case of heterogeneity <50%, a fixed effect model was used. Publication bias was determined using Begg funnel plot and the trim-and-fill method. RESULTS A total of 9 studies with 645 patients were included for final analysis after excluding one study without any seizure within either cohort. PMH patients had lower seizure rates (odds ratio, 0.393; 95% CI, 0.158-0.978) compared with non-PMH patients. The funnel plot showed a relatively asymmetric pattern, suggesting possible publication bias. After correction of the forest plot, the adjusted odds ratio was 0.362 (95% CI, 0.148-0.886), indicating significant relationships between PMH and lower incidence of seizure. CONCLUSION PMH is associated with lower seizure risk than non-PMH. However, possible publication bias could be a concern to the interpretation. Additional meta-analyses based on individual patient data from prospective large-scale studies are necessary.

Increasing Frailty Predicts Worse Outcomes and Increased Complications After Angiogram-Negative Subarachnoid Hemorrhages. World Neurosurg 2019; 134:e181-e188.

Abstract
BACKGROUND The effect of frailty on outcomes after angiogram-negative subarachnoid hemorrhages (ANSAH) is currently unknown. We investigated frailty's effects on ANSAH outcomes, including mortality and in-hospital complications. METHODS Patients from 2014 to 2018 with non-traumatic subarachnoid hemorrhage and cerebral angiograms with an unidentifiable hemorrhage source were retrospectively reviewed. The cohort was divided into non-frail (modified frailty index [mFI] = 0) and frail (mFI ≥1) groups based on pre-hemorrhage characteristics. Primary outcomes were mortality rate and discharge location. Multivariate logistic regression analyses determined predictors of ANSAH severity and primary endpoints. Receiver operating characteristic curves were used to discriminate risks for primary endpoints comparing mFI, Hunt and Hess and Fisher scores, and age. RESULTS We included 75 patients with a mean age of 55.4 ± 1.5 years, comprising 42 (56%) women, and 41 (54.7%) with perimesencephalic bleeds. A total of 32 of 75 (42.7%) patients were classified as frail. Frail individuals were 6.2 times less likely to be discharged home (odds ratio [OR] = 0.16; 95% confidence interval [CI]: 0.05-0.5; P = 0.001) and all mortalities occurred in frail patients (12.5% [n = 4 of 32]; P = 0.030). The only independent predictor of mortality was higher mFI (OR = 5.4; 95% CI: 1.5-19.1; P = 0.009), and lower mFI best predicted discharge home (OR = 0.39; 95% CI: 0.17-0.88; P = 0.023). Receiver operating characteristic analysis showed that mFI best predicted both mortality (area under the curve = 0.9718; P = 0.002) and discharge home (area under the curve = 0.7998; P < 0.001). CONCLUSIONS Frail ANSAH patients have poorer outcomes and increased mortality compared with non-frail patients. Although prospective study is needed, this information significantly impacts our understanding of ANSAH outcomes and frailty should be used for prognostication as it was a better predictor than Hunt and Hess or Fisher scores.

Abstract
Background In patients with spontaneous subarachnoid haemorrhage (SAH), a vascular cause for the bleed is not always found on initial investigations. This study aimed to systematically evaluate the delayed investigation strategies and clinical outcomes in these cases, often described as “non-aneurysmal” SAH (naSAH). Methods A systematic review was performed in concordance with the PRISMA checklist. Pooled proportions of primary outcome measures were estimated using a random-effects model. Results Fifty-eight studies were included (4473 patients). The cohort was split into perimesencephalic naSAH (PnaSAH) (49.9%), non-PnaSAH (44.7%) and radiologically negative SAH identified on lumbar puncture (5.4%). The commonest initial vascular imaging modality was digital subtraction angiography. A vascular abnormality was identified during delayed investigation in 3.9% [95% CI 1.9–6.6]. There was no uniform strategy for the timing or modality of delayed investigations. The pooled proportion of a favourable modified Rankin scale outcome (0–2) at 3–6 months following diagnosis was 92.0% [95% CI 86.0–96.5]. Complications included re-bleeding (3.1% [95% CI 1.5–5.2]), hydrocephalus (16.0% [95% CI 11.2–21.4]), vasospasm (9.6% [95% CI 6.5–13.3]) and seizure (3.5% [95% CI 1.7–5.8]). Stratified by bleeding pattern, we demonstrate a higher rate of delayed diagnoses (13.6% [95% CI 7.4–21.3]), lower proportion of favourable functional outcome (87.2% [95% CI 80.1–92.9]) and higher risk of complications for non-PnaSAH patients. Conclusion This study highlights the heterogeneity in delayed investigations and outcomes for patients with naSAH, which may be influenced by the initial pattern of bleeding. Further multi-centre prospective studies are required to clarify optimal tailored management strategies for this heterogeneous group of patients.

Abstract
OBJECTIVE To evaluate the incidence of hydrocephalus and implanted shunts in angiogram-negative subarachnoid hemorrhage (SAH) according to hemorrhage patterns: perimesencephalic SAH (PMH) versus non-PMH. METHODS The online database literature from January 1990 to November 2017 was systematically reviewed. A fixed-effect model was used when heterogeneity was <50%. A Begg funnel plot was used to assess publication bias. An additional trim and fill method was used to estimate the number of missing studies. A subgroup analysis with studies, which defined angiogram-negative SAH using repeated angiography or computed tomography angiography, was further performed. RESULTS A total of 28 articles including 2577 patients were enrolled. Patients with PMH showed a significantly decreased incidence of hydrocephalus (odds ratio [OR], 0.269; 95% confidence interval [CI], 0.208-0.348) and shunts (OR, 0.263; 95% CI, 0.169-0.411) than did patients without PMH. A subgroup analysis of 7 studies with 675 patients showed less hydrocephalus in patients with PMH than in patients without PMH (OR, 0.358; 95% CI, 0.161-0.793), with possible publication bias. Shunt procedures were marginally less common in patients with PMH compared with those patients without PMH (OR, 0.490; 95% CI, 0.236-1.018) with possible publication bias. After correction of the forest plot, the adjusted OR was 0.617 (95% CI, 0.251-1.513) for hydrocephalus and 0.618 (95% CI, 0.310-1.232) for shunts, suggesting no significant relationships between PMH and the risk of hydrocephalus or shunting. CONCLUSIONS Hydrocephalus and shunts were more evident in non-PMH than PMH. However, subgroup analyses did not show significant associations between PMH and lower risks of these events after correction for possible publication bias. Further meta-analyses based on individual patient data are necessary.

Abstract
OBJECTIVE To report clinical outcomes of delayed cerebral ischemia (DCI) and vasospasm in angiogram-negative subarachnoid hemorrhage (SAH) according to hemorrhage patterns, perimesencephalic hemorrhage (PMH) and non-PMH. METHODS Online databases from January 1990 to December 2017 were systematically reviewed. A fixed-effects model was used to control heterogeneity. To resolve publication bias, the trim and fill method was used to estimate number of missing studies and adjusted odds ratio (OR). Subgroup analysis of data from studies that defined angiogram-negative subarachnoid hemorrhage by angiography repeated at least twice or computed tomography angiography was performed. RESULTS Among 24 studies including 2083 patients, 23/985 patients (2.3%) with PMH and 144/1098 patients (13.1%) with non-PMH had DCI, indicating that patients with PMH experienced significantly lower DCI than patients with non-PMH (OR = 0.219; 95% confidence interval [CI], 0.144-0.334). Regarding vasospasm, 99/773 patients (12.8%) with PMH and 231/922 patients (25.1%) with non-PMH exhibited vasospasm, indicating that patients with PMH experienced significantly lower vasospasm than patients with non-PMH (OR = 0.445; 95% CI, 0.337-0.589). Funnel plots show asymmetry indicating possible publication bias. After trimming 10 studies for DCI and 7 for vasospasm, the adjusted ORs remained significant between PMH and lower risks of DCI and vasospasm. Subgroup analysis of 789 patients in 8 studies showed a lower risk of DCI (OR = 0.268; 95% CI, 0.151-0.473) and vasospasm (OR = 0.346; 95% CI, 0.221-0.538) in patients with PMH. CONCLUSIONS PMH showed a significantly lower risk of DCI and vasospasm than non-PMH. Clinical outcomes of angiogram-negative subarachnoid hemorrhage, based on meta-analysis of individual patient data, need to be investigated.
