The diagnostic yield of repeat computed tomography angiography in cases of spontaneous subarachnoid haemorrhage after negative initial digital subtraction angiography. Pol J Radiol 2024; 89:e179-e186.

Abstract
Purpose It is currently unclear how useful repeat computed tomography angiography (CTA) is in spontaneous subarachnoid haemorrhage (SAH) patients after negative initial digital subtraction angiography (DSA). The purpose of this study is to assess the yield of repeat CTA for the detection of causative vascular lesions in patients with SAH in whom there has been a negative initial DSA. Material and methods This observational retrospective study was carried out from January 2013 to July 2022 at a single institution. Analysis of the SAH pattern on unenhanced CT showed that patients were divided into perimesencephalic SAH and diffuse SAH groups. A repeat CTA was performed on all spontaneous SAH patients who had a nega-tive initial CTA and DSA within a 2-week period. An interventional neuroradiologist and a diagnostic radiologist examined all images to search for causative vascular abnormalities. Results Forty-seven patients were included in our study, with a median age of 55 years and a range of 28-81 years. Thirty-seven had diffuse SAH (66%), and 16 had perimesencephalic SAH (34%). The repeat CTA revealed 2 causa-tive vascular lesions (a right PICA aneurysm and a mycotic aneurysm) in 2 separate patients (yield of 4.3%), both of whom had diffuse SAH (yield of 6.5%). In retrospect, none of these vascular lesions were evident in the initial CTA and DSA. No evidence of re-bleeding was observed in the follow-up period. Conclusions It is beneficial to repeat CTA when evaluating patients with diffuse SAH who initially present with nega-tive initial DSA. For occult aneurysms, the diagnostic yield of the follow-up CTA is 6.5%.

Abstract
Spontaneous non-aneurysmal subarachnoid haemorrhage (NAPMSAH) (addressing point 1) is a relatively rare occurrence in clinical settings as it is rarely misdiagnosed and usually involves a significantly better prognosis than the classical aneurysmal pattern. We hereby focused on a comprehensive analysis of this distinct pathological entity with the purpose of analysing possible pathophysiological entities, outcomes and treatment options involving this diagnosis with a focus on demographical, epidemiological and clinical data. The clinical setting includes focal neurological signs related to the anatomical structures, while computer tomography followed by tomographic angiography are the most common diagnosis tools, with a typical hyperdense lesion involving the midbrain, fourth ventricle and subthalamic areas without an angiographic correspondent, such as an aneurysmal pathology. Further investigations can also be used to highlight this diagnosis, such as interventional angiography or magnetic resonance imaging. Given the rarity of this condition and its relatively better prognosis, treatment options usually remain conservative. In the present review, the main characteristics of NAPMSAH are discussed.

Abstract
Background Despite having an overall benign course, non‐traumatic non‐aneurysmal subarachnoid hemorrhage (naSAH) is still accompanied by a risk of clinical complications and poor outcomes. Risk factors and mechanisms of complications and poor outcomes after naSAH remain unknown. Our aim was to explore the effect of stress‐induced hyperglycemia (SIH) on complication rates and functional outcomes in naSAH patients. Methods We retrospectively reviewed patients with naSAH admitted to our institution between 2013 and 2018. SIH was identified according to previous criterion. Symptomatic vasospasm, delayed cerebral infarction, and hydrocephalus were identified as main complications. Outcomes were reviewed using a modified Rankin Scale (mRS) at discharge, 3 months, and 12 months. A statistical analysis was conducted to reveal the associations of SIH with complications and outcomes. Results A total of 244 naSAH patients were included in the cohort with 74 (30.3%) SIH. After adjusting for age, gender, hypertension, Hunt and Hess (HH) grade, modified Fisher Scale (mFS), intraventricular hemorrhage (IVH), and subarachnoid blood distribution, SIH was significantly associated with symptomatic vasospasm (p < 0.001, 12.176 [4.904–30.231]), delayed cerebral infarction (p < 0.001, 12.434 [3.850–40.161]), hydrocephalus (p = 0.008, 5.771 [1.570–21.222]), and poor outcome at 12 months (p = 0.006, 5.506 [1.632–18.581]), whereas the correlation between SIH and poor outcome at discharge (p = 0.064, 2.409 [0.951–6.100]) or 3 months (p = 0.110, 2.029 [0.852–4.833]) was not significant. Incorporation of SIH increased the area under curve (AUC) of ROC in the combined model for predicting symptomatic vasospasm (p = 0.002), delayed cerebral infarction (p = 0.024), hydrocephalus (p = 0.037), and 12‐month poor outcome (p = 0.087). Conclusions SIH is a significant and independent risk factor for symptomatic vasospasm, delayed cerebral infarction, hydrocephalus, and long‐term poor outcome in naSAH patients. Identifying SIH early after naSAH is important for decision‐making and treatment planning.

Abstract
Distinguishing the aneurysmal from nonaneurysmal subarachnoid hemorrhage (SAH) may be difficult as acute bleeding in the subarachnoid space is a common denominator. It is believed that toxic effects of breakdown products of acute bleed, including hemoglobin, contribute to the morbidity and mortality of this condition; and that early drainage will potentially reduce them. This series focuses on our local experience with the application of external cerebrospinal fluid (CSF) drainage in the management of a series of cases confirmed to be nonaneurysmal SAH and its effects on the outcome. The objective of this report is to observe the usefulness of external CSF drainage in the management of nonaneurysmal SAH. Five consecutive cases over four years were reviewed and reported as a case series. The main points we focused on were presentation, diagnostic findings on imaging, CSF drainage, and outcome up to six months. All the patients presented with headaches described as sudden, and only one had significant impairment of consciousness Glasgow Coma Scale (GCS) 10/15. Three out of the five patients had a premorbid hypertensive condition of unclear control status. We also observed that three out of the five had a low-pressure pretruncal/perimesencephalic pattern of bleed, whereas two had the typical high-pressure SAH pattern. CT angiography (CTA) was negative in all. Four had lumbar drainage, while one had external ventricular drainage. All were discharged within three weeks and functioned optimally at six months. CSF drainage in managing nonaneurysmal SAH is achievable with minimal access procedures, including lumbar drain (LD) and external ventricular drainage (EVD), which may have further reduced the low morbidity normally associated with this condition.

Abstract
Aim: To determine the risk factors affecting outcome at the end of 90 days of post-angiogram-negative subarachnoid hemorrhage (SAH). Methods: Non-traumatic SAH cases were reviewed from the case records of patients who had reported to the Department of Neurology of a tertiary care hospital and 50 angio-negative SAH cases were included after excluding all the cases with known cause of hemorrhage after doing computed tomography angiography (CTA)/digital subtraction angiography (DSA). The presence of hypertension, diabetes mellitus, coronary artery disease (CAD), history of alcohol and smoking, and various scales like Hunt and Hess Scale (HHS), World Federation of Neurological Surgeons (WFNS), and Fisher scale had been recorded at admission. The outcome was assessed at 90 days post-SAH using the Modified Rankin Scale (mRS). Statistical analyses: The association between the outcome and the factors was assessed using the Pearson Chi-Square test and the risk factors/predictors of outcome were assessed using logistic regression. Results: The following variables were important risk factors for predicting poor outcome of angio-negative SAH (mRS 3 to 6): hypertension (P = 0.011), diabetes mellitus (P = 0.032), being an alcoholic (P = 0.019), HHS grade 4 to 5 (P < 0.01), and WFNS grade 4 to 5 (P < 0.01). On multivariate regression analysis, hypertension (P = 0.032) was an independent predictor of unfavorable outcome. Conclusions: At time of admission, presence of hypertension, diabetes mellitus, history of alcohol consumption, and poor grades of HHS and WFNS scale are predictors of poor outcome of angio-negative SAH.

Repeat Catheter Angiography in Patients with Aneurysmal-Pattern Angiographically Negative Subarachnoid Hemorrhage. Neurocrit Care 2021; 36:52-60. [PMID: 34184178 DOI: 10.1007/s12028-021-01247-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2020] [Accepted: 03/30/2021] [Indexed: 10/21/2022]
Abstract
BACKGROUND A significant proportion of patients with subarachnoid hemorrhage have a normal cerebral angiogram. Patients with angiographically negative subarachnoid hemorrhage (anSAH) with either perimesencephalic- (panSAH) or aneurysmal-pattern hemorrhage (aanSAH, also known as diffuse anSAH) have an excellent prognosis, but only if underlying vascular abnormalities are completely excluded. The rate of occult aneurysms in patients with aanSAH varies widely across studies. The purpose of this study was to quantify the value of repeat DSA in these patients. METHODS We reviewed the records of all patients initially diagnosed with aanSAH after a screening DSA at a single tertiary neurovascular referral center from January 2006-April 2018. Patients with panSAH and traumatic SAH were excluded. We also performed a systematic review and meta-analysis of positive second DSAs in previously published case series of patients with aanSAH who underwent two serial DSAs. For meta-analysis, PubMed Central, MEDLINE and Cochrane Library databases were searched for pertinent studies up to November 2019. The rate of aneurysm detection on repeat angiography was extracted from each study. Pooled rates for positive second angiogram were calculated as untransformed proportions in a binary random-effects model meta-analysis. Inter-study heterogeneity was calculated using an I2 statistic. RESULTS Three of 27 patients (11.1%) with aanSAH and at least two DSAs were subsequently found to have a cerebral aneurysm in our institutional dataset. Twenty-six studies in our systematic review met inclusion criteria, and the pooled rate of positive second angiogram was 10.4% (95% CI 7.3%-13.5%, P < 0.001). Substantial inter-study heterogeneity was observed in the meta-analysis (I2 = 61.7%, P < 0.001). CONCLUSIONS One in 10 patients with aanSAH has an occult ruptured aneurysm. A second-look DSA should be strongly considered in these cases.

Abstract
BACKGROUND Subarachnoid hemorrhage (SAH) from an intracranial aneurysmal rupture is the most common nontraumatic etiology for SAH, but up to 15% of patients with SAH have no identifiable source. OBJECTIVE To assess familial predisposition to spontaneous nonaneurysmal SAH (naSAH) and to evaluate whether family history affects the severity of presentation and prognosis of this condition. METHODS We conducted a retrospective analysis of all spontaneous SAH with negative digital subtraction angiography from 2004 to 2018. Patients were divided into 2 groups: patients with first- or second-degree relatives with intracranial aneurysms and patients with no family history. Univariate and multivariate regression analyses were used to study patient presentation, radiographic patterns of hemorrhage, and clinical outcome. RESULTS A total of 100 patients met the inclusion criteria. There were no individuals with family history of naSAH. A total of 15 patients (15%) had at least one family member with an intracranial aneurysm, of which 12 (12%) presented as SAH. Patients without family history had a higher percentage of perimesencephalic presentation, whereas those with family history had a higher percentage of nonperimesencephalic SAH presentation (47% vs 13%, odds ratio [OR] 0.17 [95% CI 0.04, 0.81]). CONCLUSION We found a high rate of family history of intracranial aneurysms in patients who presented with naSAH. Although there was no difference in clinical outcome in patients with and without family history, there appears to be a higher percentage of nonperimesencephalic radiographic patterns of SAH in those with family history, suggesting possible different etiologies of these hemorrhages.

Abstract
Objective
Despite the technological advancement in imaging, digital subtraction angiography (DSA) remains gold standard imaging modality for spontaneous subarachnoid hemorrhage (SAH). But even after DSA, around 15% of SAH remains elusive for the cause of the bleed. This is an institutional review to solve the mystery, “when is second DSA really indicated?”
Methods
In a retrospective review from January 2015 to December 2017, we evaluated cases of spontaneous SAH with initial negative DSA with repeat DSA after 6 weeks to rule out vascular abnormality. The spontaneous SAH was confirmed on noncontrast computed tomography (NCCT) and divided into two groups of perimesencephalic SAH (PM-SAH) or nonperimesencephalic SAH (nPM-SAH). The outcome was assessed by a modified Rankin’s score (mRS) at 6 months postictus.
Results
During the study period, we had 119 cases of initial negative DSA and 98 cases (82.3%) underwent repeat DSA after 6 weeks interval. A total of 53 cases (54.1%) had PM-SAH and 45 cases (45.9%) had nPM-SAH. Repeat DSA after 6 weeks showed no vascular abnormality in 53 cases of PM-SAH and in 2 (4.4%) out of 45 cases of nPM-SAH. At 6 months postictus, all cases of PM-SAH and 93% of nPM-SAH had mRS of 0.
Conclusion
We recommend, a repeat DSA is definitely not required in PM-SAH, but it should be done for all cases of nPM-SAH, before labeling them as nonaneurysmal SAH. Although the overall outcome for nonaneurysmal spontaneous SAH is better than aneurysmal SAH, nPM-SAH has poorer eventual outcome compared to PM-SAH.

Abstract
Objectives: Subarachnoid hemorrhage (SAH) with negative angiographic findings has a heterogeneous nature with variations in clinical course and outcome as compared to the aneurysmal SAH. It makes up to 15% of the spontaneous SAH and is characterized by milder clinical presentation. The purpose of this study was the analyses of risk factors, clinical observations, radiologic characteristics, and outcome in patients with nonaneurysmal SAH (NA-SAH). Patients and Methods: In a retrospective design, 77 consecutive patients with NA-SAH were recruited from May 2008, to October 2018. All patients underwent conventional cerebral angiography. We stratified patients into two groups based on the distribution of blood on their CT scan into perimesencephalic (PM) and non-PM (NPM) SAH. We performed the Outcome using Glasgow Coma Scale (GCS) and modified Rankin scale (favorable mRS 0–2 vs. unfavorable mRS 3–6). Data were analyzed using IBM® SPSS® Statistics V22.0. Results: The mean age at presentation was 48.5 ± 8.4 years with male predominance (71.4%). About 76.7% of the patients had headache and vomiting, most of the patients (75.3%) presented with GCS 15 at initial clinical presentation (61.03%) had NPM versus (38.96%) with PM characters in computed tomography scans. Fourteen (17.9%) patients developed hydrocephalus and 12 (15.3%) needed external ventricular drain placement, while none of the patients needed permanent shunt placement. However, all patients had a favorable clinical and functional outcome at discharge and at late follow-up (up to 3 months). Conclusions: NA-SAH does not affect the short- and long-term prognosis. In our results, the pattern of bleeding affects the initial presentation, clinical course, and complications. The clinical and functional outcomes in the majority of our patients were comparable in both groups with good prognosis. Hypertension, smoking, and elevated venous pressure, such as a history of deep venous thrombosis and asthma might be considered as a risk factor.

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.

Elevated C-reactive protein and white blood cell count at admission predict functional outcome after non-aneurysmal subarachnoid hemorrhage. J Neurol 2018; 265:2944-2948. [PMID: 30317466 DOI: 10.1007/s00415-018-9091-5] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2018] [Revised: 10/08/2018] [Accepted: 10/10/2018] [Indexed: 12/30/2022]
Abstract
INTRODUCTION Patients with non-aneurysmal subarachnoid hemorrhage (SAH) are considered to have an overall benign course of disease compared to patients suffering from aneurysmal SAH. Nevertheless, a small but significant number of such patients might only achieve unfavorable outcome. Therefore, the purpose of the present study was to determine if routine laboratory markers of acute phase response are associated with unfavorable outcome in patients with non-aneurysmal SAH. METHODS From 2006 to 2017, 154 patients suffering from non-aneurysmal SAH were admitted to our institution. Patients were stratified according to the distribution of cisternal blood into patients with perimesencephalic SAH (pSAH) versus non-perimesencephalic SAH (npSAH). C-reactive protein (CRP) and white blood cells (WBC) assessments were performed within 24 h of admission as part of routine laboratory workup. Outcome was assessed according to the modified Rankin Scale (mRS) after 6 months and stratified into favorable (mRS 0-2) vs. unfavorable (mRS 3-6). RESULTS The multivariate regression analysis revealed "CRP > 5 mg/l" (p = 0.004, OR 143.7), "WBC count > 12.1 G/l" (p = 0.006, OR 47.8), "presence of IVH" (p = 0.02, OR 13.5), "poor-grade SAH" (p = 0.01, OR 45.2) and "presence of CVS" (p = 0.003, OR 149.9) as independently associated with unfavorable outcome in patients with non-aneurysmal SAH. CONCLUSION Elevated C-reactive protein and WBC count at admission were associated with unfavorable outcome after non-aneurysmal SAH.

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.

Abstract
OBJECTIVE More nonaneurysmal subarachnoid hemorrhage (NaSAH) are found in clinical practice. However, the precise mechanisms in which d-dimer level is associated with clinical condition in patients with NaSAH remain unclear. But even more, the data assessing the risk of clinical course in the patients with NaSAH are scarce. Our objective was to investigate whether d-dimer levels correlated with complication and outcome in patients with NaSAH. METHODS Between February 2013 and May 2017, 92 patients suffering from NaSAH were treated in our hospital. Patient characteristics, radiologic features, laboratory findings, complications, and outcomes were analyzed retrospectively. Patients were stratified into the perimesencephalic (PM) subarachnoid hemorrhage (SAH) group and the nonperimesencephalic (NPM) SAH group according to the bleeding type, and the NPM-SAH group was further divided into 2 subgroups into the NPM-elevated group and the NPM-normal group based on the value of the d-dimer. After statistical analysis, the NPM-SAH and PM-SAH groups were compared; the same was true for the NPM-elevated group and the NPM-normal group. RESULTS The rate of complications in the NPM-SAH group was higher than in the PM-SAH group, including early hydrocephalus, delayed cerebral ischemia, clinical vasospasm, pneumonia, and hyponatremia. Our results showed that d-dimer levels in patients with NPM-SAH were more elevated than in those with PM-SAH. Further analysis of subgroups demonstrated that patients with elevated d-dimer levels had a higher incidence of complications than those with normal d-dimer levels, especially the risks of shunt-dependent hydrocephalus and pneumonia. In addition, disability, and even death, could be seen in patients with higher levels of d-dimer, but the long-term outcomes were not particularly obvious between these groups. CONCLUSIONS Elevated d-dimer levels on admission were significantly associated with complication in patients with NPM-SAH. In addition to conventional radiologic diagnosis, d-dimer levels can increase the ability of a rapid differential diagnosis between NPM-SAH and PM-SAH.

Risk factors for shunt dependency in patients suffering from spontaneous, non-aneurysmal subarachnoid hemorrhage. Neurosurg Rev 2018; 42:139-145. [PMID: 29594703 DOI: 10.1007/s10143-018-0970-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2017] [Revised: 03/14/2018] [Accepted: 03/20/2018] [Indexed: 10/17/2022]
Abstract
Patients presenting with spontaneous, non-aneurysmal subarachnoid hemorrhage (SAH) achieve better outcomes compared to patients with aneurysmal SAH. Nevertheless, some patients develop shunt-dependent hydrocephalus during treatment course. We therefore analyzed our neurovascular database to identify factors determining shunt dependency after non-aneurysmal SAH. From 2006 to 2016, 131 patients suffering from spontaneous, non-aneurysmal SAH were admitted to our department. Patients were stratified according to the distribution of cisternal blood into patients with perimesencephalic SAH (pSAH) versus non-perimesencephalic SAH (npSAH). Outcome was assessed according to the modified Rankin Scale (mRS) at 6 months and stratified into favorable (mRS 0-2) versus unfavorable (mRS 3-6). A multivariate analysis was performed to identify predictors of shunt dependency in patients suffering from non-aneurysmal SAH. Overall, 18 of 131 patients suffering from non-aneurysmal SAH developed shunt dependency (14%). In detail, patients with npSAH developed significantly more often shunt dependency during treatment course, when compared to patients with pSAH (p = 0.02). Furthermore, patients with acute hydrocephalus, presence of intraventricular hemorrhage, presence of clinical vasospasm, and anticoagulation medication prior SAH developed significantly more often shunt dependency, when compared to patients without (p < 0.0001). However, "acute hydrocephalus" was the only significant and independent predictor for shunt dependency in all patients with non-aneurysmal SAH in the multivariate analysis (p < 0.0001). The present study identified acute hydrocephalus with the necessity of CSF diversion as significant and independent risk factor for the development of shunt dependency during treatment course in patients suffering from non-aneurysmal SAH.

Cerebral Vasospasm-Dependent and Cerebral Vasospasm-Independent Cerebral Infarctions Predict Outcome After Nonaneurysmal Subarachnoid Hemorrhage: A Single-Center Series with 250 Patients. World Neurosurg 2017; 106:861-869.e4. [PMID: 28711533 DOI: 10.1016/j.wneu.2017.07.017] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2017] [Revised: 06/30/2017] [Accepted: 07/03/2017] [Indexed: 12/28/2022]
Abstract
OBJECTIVE The number of patients with nonaneurysmal subarachnoid hemorrhage (naSAH) has increased during the last decade. Data regarding infarctions in naSAH are still limited. The aim of this study was to identify the rate of cerebral vasospasm (CVS)-dependent and CVS-independent infarctions and their influence on clinical outcomes. METHODS Between 1999 and 2015, 250 patients suffering from naSAH were analyzed retrospectively. A delayed infarction was analyzed whether it was associated with CVS (CVS-dependent infarction) or not (CVS-independent). RESULTS A total of 36 patients (14%) had cerebral infarctions. CVS was detected in 54 patients (22%), and 15 (6%) of them developed infarctions (CVS-dependent). Infarctions without signs of CVS (CVS-independent) occurred in 21 patients (8%). Overall, 86% of the patients had favorable outcome. Patients without cerebral infarctions had the best outcome (91% favorable outcome, 5% mortality rate). Patients with CVS-independent infarctions (57%) as well as patients with CVS-dependent infarctions (53%) had a favorable outcome less often. The mortality rate was also significantly greater in patients with CVS-independent (19%) and CVS-dependent infarctions (33%). A further independent predictor was anticoagulative therapy, which increased during study period and was associated with nonperimesencephalic blood distribution. CONCLUSIONS CVS-dependent and independent infarctions occur in naSAH and contribute to unfavorable outcomes. Whereas CVS-independent infarctions occur in any subgroup, CVS-dependent infarctions seem to be associated with blood pattern (Fisher 3). Anticoagulative therapy seems to be not only a predictor for worse outcome but also for nonperimesencephalic SAH. Accordingly, the proportion of perimesencephalic and nonperimesencephalic SAH changed during the study period (from 2.2:1 to 1:1.7).

Abstract
Abstract
BACKGROUND
The angiogram-negative subarachnoid hemorrhage (SAH) literature includes patients with perimesencephalic hemorrhage, which is recognized to have a much better outcome than aneurysmal SAH.
OBJECTIVE
To evaluate the clinical outcomes of Nonperimesencephalic Angiogram-Negative SAH (NPAN-SAH).
METHODS
A prospective, spontaneous SAH database of 1311 patients that accrued between April 2006 and December 2014 was screened. All patients with NPAN-SAH and 2 consecutive negative cerebral angiograms were included.
RESULTS
We identified 191 (11%) from a total of 1311 patients with spontaneous SAH. Amongst angiogram-negative patients, 83 (4.9%) were adjudicated to have NPAN-SAH. Patient characteristics were similar across the groups, except NPAN-SAH patients were more likely to be men and had higher rates of diabetes. In a multivariable logistic regression model, NPAN-SAH patients were less likely to develop vasospasm, after adjusting for Fisher grade, sex, and diabetes (odds ratio [OR]: 0.197, 95% confidence interval [CI; 0.07-0.55], P = .002). In another adjusted model accounting for Hunt and Hess clinical grade, NPAN-SAH patients were also less likely to develop vasospasm (OR: 0.2, 95% CI [0.07-0.57], P = .002). We found no statistical significance between 2 groups for rebleed, developing hydrocephalus, seizures, or delayed cerebral ischemia. NPAN-SAH patients were equally associated with poor functional outcome (modified Rankin scale ≥3; OR: 1.16, 95% CI [0.615-2.20], P = .6420), and death (OR: 1.22, 95% CI [0.362-4.132], P = .7455) compared to aneurysmal SAH.
CONCLUSION
Although the risk of vasospasm may be lower, patients with NPAN-SAH are equally associated with delayed cerebral ischemia, poor outcome, and death as compared to patients with aneurysmal SAH. Furthers studies may be necessary to further clarify these findings

Abstract
Background. The ideal management of SAH patients with negative initial DSA findings remains unresolved. Objective. (i) To present risk factors, clinical courses, and outcomes in different types of SAH patients with negative DSA findings; (ii) to explore the differences of basal vein between aSAH patients and NASAH patients; and (iii) to evaluate the value of repeated DSA for these patients. Methods. All SAH patients with negative initial DSA findings between 2013 and 2015 in our hospital were enrolled and were further categorized as perimesencephalic SAH (PMN-SAH) or nonperimesencephalic SAH (nPMN-SAH). Risk factors, clinical courses, outcomes, and the basal vein drainage patterns were compared. Results. A total of 137 patients were enrolled in the present study. The PMN-SAH group had better GOS and mRS values at 1-year follow-up. Moreover, the nPMN-SAH group had a higher rate of complications. The basal vein drainage pattern showed significant difference when comparing each of the NASAH subtypes with aSAH groups. There was a significant higher rate of a responsible aneurysm in nPMN-SAH group upon repeated DSA. Conclusions. SAH patients with negative initial DSA findings had benign clinical courses and outcomes. Repeated DSA studies are strongly advised for patients with the nPMN-SAH pattern.

Abstract
BACKGROUND Nontraumatic spontaneous subarachnoid hemorrhage (SAH) is associated with a high mortality. This study was conducted to investigate the epidemiological features of nontraumatic spontaneous SAH in China. METHODS From January 2006 to December 2008, the clinical data of patients with nontraumatic SAH from 32 major neurosurgical centers of China were evaluated. Emergent digital subtraction angiography (DSA) was performed for the diagnosis of SAH sources in the acute stage of SAH (≤3 days). The results and complications of emergent DSA were analyzed. Repeated DSA or computed tomography angiography (CTA) was suggested 2 weeks later if initial angiographic result was negative. RESULTS A total of 2562 patients were enrolled, including 81.4% of aneurysmal SAH and 18.6% of nonaneurysmal SAH. The total complication rate of emergent DSA was 3.9% without any mortality. Among the patients with aneurysmal SAH, 321 cases (15.4%) had multiple aneurysms, and a total of 2435 aneurysms were detected. The aneurysms mostly originated from the anterior communicating artery (30.1%), posterior communicating artery (28.7%), and middle cerebral artery (15.9%). Among the nonaneurysmal SAH cases, 76.5% (n = 365) had negative initial DSA, including 62 cases with peri-mesencephalic nonaneurysmal SAH (PNSAH). Repeated DSA or CTA was performed in 252 patients with negative initial DSA, including 45 PNSAH cases. Among them, the repeated angiographic results remained negative in 45 PNSAH cases, but 28 (13.5%) intracranial aneurysms were detected in the remaining 207 cases. In addition, brain arteriovenous malformation (AVM, 7.5%), Moyamoya disease (7.3%), stenosis or sclerosis of the cerebral artery (2.7%), and dural arteriovenous fistula or carotid cavernous fistula (2.3%) were the major causes of nonaneurysmal SAH. CONCLUSIONS DSA can be performed safely for pathological diagnosis in the acute stage of SAH. Ruptured intracranial aneurysms, AVM, and Moyamoya disease are the major causes of SAH detected by emergent DSA in China.

Abstract
Objective To compare the clinical evolution of perimesencephalic subarachnoid
hemorrhage and non-perimesencephalic subarachnoid hemorrhage. Methods The study was conducted retrospectively in a tertiary hospital center in the
north region of Portugal. Included patients had no identifiable cause for
subarachnoid hemorrhage. Several epidemiologic, clinical and imaging aspects
were statistically analyzed, taking into account the differences in
perimesencephalic subarachnoid hemorrhage and non-perimesencephalic
subarachnoid hemorrhage. Results Sixty-two patients met the inclusion criteria (46.8% - perimesencephalic
subarachnoid hemorrhage; 53.2% - non-perimesencephalic subarachnoid
hemorrhage). Demographic and clinical background characteristics were
similar in both groups. Complications were more frequent in patients with
non-perimesencephalic subarachnoid hemorrhage - 84.8% of the patients had at
least one complication versus 48.3% in perimesencephalic subarachnoid
hemorrhage. Vasospasm, infection and hydrocephaly were the most common
complications (each was detected more frequently in the
non-perimesencephalic subarachnoid hemorrhage group than in
perimesencephalic subarachnoid hemorrhage group). Two patients died, both
had a non-perimesencephalic subarachnoid hemorrhage. The median inpatient
time was longer in the non-perimesencephalic subarachnoid hemorrhage group
(21 versus 14 days). No incidents of rebleeding were reported during the
follow-up period (mean time of 15 ± 10.3 months). Conclusion Perimesencephalic subarachnoid hemorrhage and non-perimesencephalic
subarachnoid hemorrhage are two different entities that have different
clinical outcomes, namely in terms of complication rate and median inpatient
time. The management of these patients should respect this difference to
improve treatment and optimize health care resources.

Abstract
BACKGROUND AND PURPOSE Aneurysmal-type subarachnoid hemorrhage is a serious disease with high morbidity and mortality. When no aneurysm is found, the patient remains at risk for rebleeding. Negative findings for SAH on angiography range from 2% to 24%. Most previous studies were based on conventional 2D imaging. 3D rotational angiography depicts more aneurysms than 2D angiography. The purpose of this study was to evaluate the yield of repeat 3D rotational angiography in patients with aneurysmal-type SAH with negative initial 3D rotational angiography findings and to classify the initial occult aneurysms. MATERIALS AND METHODS Between March 2013 and January 2016, 292 patients with SAH and an aneurysmal bleeding pattern were admitted. Of these 292 patients, 30 (10.3%; 95% CI, 7.3%-14.3%) had initial negative 3D rotational angiography findings within 24 hours. These patients underwent a second 3D rotational angiography after 7-10 days. RESULTS In 8 of 30 patients (26.7%; 95% CI, 14.0%-44.7%) with initial negative 3D rotational angiography findings, a ruptured aneurysm was found on repeat 3D rotational angiography. Three of 8 initial occult aneurysms were very small (1-2 mm), 2 were supraclinoid carotid artery dissecting aneurysms (2 and 8 mm), 2 were small (1 and 3 mm) basilar perforator aneurysms, and 1 was a 3-mm vertebral artery dissecting aneurysm. CONCLUSIONS In 10% of patients with aneurysmal-type SAH, initial 3D rotational angiography findings were negative, and in 1 in 4, repeat 3D rotational angiography demonstrated a ruptured aneurysm. Initial occult aneurysms were dissecting aneurysms of perforators or main arteries or were very small (1-2 mm) or both. Our results indicate that repeat 3D rotational angiography is mandatory in patients with initial 3D rotational angiography findings negative for aneurysmal-type SAH.

Abstract
OBJECT
Subarachnoid hemorrhage (SAH) is usually caused by a ruptured intracranial aneurysm, but in some patients no source of hemorrhage can be detected. More recent data showed increasing numbers of cases of spontaneous nonaneurysmal SAH (NASAH). The aim of this study was to analyze factors, especially the use of antithrombotic medications such as systemic anticoagulation or antiplatelet agents (aCPs), influencing the increasing numbers of cases of NASAH and the clinical outcome.
METHODS
Between 1999 and 2013, 214 patients who were admitted to the authors’ institution suffered from NASAH, 14% of all patients with SAH. Outcome was assessed according to the modified Rankin Scale (mRS) at 6 months. Risk factors were identified based on the outcome.
RESULTS
The number of patients with NASAH increased significantly in the last 15 years of the study period. There was a statistically significant increase in the rate of nonperimesencephalic (NPM)-SAH occurrence and aCP use, while the proportion of elderly patients remained stable. Favorable outcome (mRS 0–2) was achieved in 85% of cases, but patients treated with aCPs had a significantly higher risk for an unfavorable outcome. Further analysis showed that elderly patients, and especially the subgroup with a Fisher Grade 3 bleeding pattern, had a high risk for an unfavorable outcome, whereas the subgroup of NPM-SAH without a Fisher Grade 3 bleeding pattern had a favorable outcome, similar to perimesencephalic (PM)-SAH.
CONCLUSIONS
Over the years, a significant increase in the number of patients with NASAH has been observed. Also, the rate of aCP use has increased significantly. Risk factors for an unfavorable outcome were age > 65 years, Fisher Grade 3 bleeding pattern, and aCP use. Both “PM-SAH” and “NPM-SAH without a Fisher Grade 3 bleeding pattern” had excellent outcomes. Patients with NASAH and a Fisher Grade 3 bleeding pattern had a significantly higher risk for an unfavorable outcome and death. Therefore, for further investigations, NPM-SAH should be stratified into patients with or without a Fisher Grade 3 bleeding pattern. Also, cases of spontaneous SAH should be stratified into NASAH and aneurysmal SAH.

Abstract
BACKGROUND A recently published prospective study identified an impaired outcome of patients with non-perimesencephalic (NPM) subarachnoid hemorrhage (SAH). Our objective was to analyze the long-term outcome of patients with subsequent rehabilitation after NPM SAH. METHODS A comparison of patients with NPM SAH receiving subsequent in-patient rehabilitation was done at discharge (using the modified Rankin scale (mRS)), short-term outcome after 6 months (mRS), and prospectively using a questionnaire (short-form health survey with 36 questions (SF-36)), which was sent to 66 patients. RESULTS Thirty-seven patients answered the SF-36, on average 6.3 years after ictus (range 1.5-14 years). After NPM SAH, the mRS is impaired. Patients with subsequent rehabilitation had a significant better improvement until short-term follow-up. Until long-term outcome, the psychological items were non-significantly reduced, whereas all physical items (physical functioning, role limitations because of physical health problems, bodily pain, and general health perceptions) were significantly decreased compared to the standard population. In patients with subsequent rehabilitation, all items were only non-significantly reduced. About 16% of the patients developed secondary neurological and/or psychiatric diseases. CONCLUSIONS The quality of life (QoL) is decreased after NPM SAH. In the long-term follow-up, a significant reduction in physical items was identified. Due to subsequent in-patient rehabilitation after NPM SAH, the impairment can be improved significantly until short-term follow-up. Whereas patients with NPM SAH had a significantly decreased QoL at long-term follow-up, for patients with rehabilitation, the QoL was only slightly (non-significantly) reduced. Therefore, patients should receive subsequent rehabilitation after NPM SAH to improve the functional short-term outcome (mRS) and long-term QoL. www.clinicaltrials.gov (Identifier No. NCT02334657).

Abstract
OBJECTIVE Recent data have shown increasing numbers of non-aneurysmal subarachnoid hemorrhage (NASAH). However, data are limited and often only small series have been published. Our objective was to analyze the rate of cerebral vasospasm (CVS), delayed cerebral infarction (DCI), and their influence on the clinical outcome, especially in patients with diffuse Fisher 3 bleeding pattern NASAH (Fi3). METHODS Between 1999 and 2014, 225 patients had NASAH. CVS, DCI, and outcome (according to the modified Rankin Scale at 6 months) were analyzed retrospectively. Patients were stratified according to the bleeding type. After univariate analysis a multivariate analysis was performed and NASAH Fi3 was also compared with aneurysmal SAH Fi3. RESULTS Patient characteristics and the outcome of perimesencephalic (PM) and non-PM (NPM) SAH were similar. Excluding Fi3, PM and NPM without Fi3 had similar patient characteristics, clinical course, and outcome. In particular, the Fi3 subgroup had a significantly increased risk of CVS, DCI, unfavorable outcome, hydrocephalus, and death. Early hydrocephalus was associated with Fi3 and intraventricular hemorrhage. The multivariate regression model showed the variables elderly patients, Fi3, and early hydrocephalus as independent and significant predictors for an unfavorable outcome. A further comparison of NASAH Fi3 with aneurysmal SAH Fi3 showed similar characteristics, CVS rate, and mortality. CONCLUSIONS Patients with NASAH without a Fi3 bleeding pattern had a similar excellent outcome to patients with PM-SAH. Patients with Fi3 had a high risk for early hydrocephalus, CVS, DCI, and an unfavorable outcome, similar to patients with aneurysmal SAH. After multivariate analysis, early hydrocephalus, elderly patients, and Fi3 were identified as negative prognostic factors. Therefore, patients with Fi3 are at risk and need careful clinical observation.

Abstract
BACKGROUND Multiple investigations are usually performed in patients with spontaneous SAH who have negative initial angiography. This study aimed to evaluate the most appropriate use of additional imaging studies and how this may be influenced by the findings of the initial CT. METHODS A retrospective analysis was performed on a prospectively collected cohort of patients referred with spontaneous SAH and negative initial angiography. The patients were divided into four categories based upon the distribution of blood on the initial CT: perimesencephalic (pSAH), diffuse (dSAH), sulcal (sSAH) and CT negative (CSF positive for xanthochromia) (nCT-pLP). The number and nature of the subsequent imaging investigations were reviewed, and the results were correlated with the findings of the presenting CT. RESULTS One hundred fourteen patients were included in the study. Repeat imaging found five relevant abnormalities. Three cases of vasculitis were diagnosed on the first DSA following a negative CTA. A case of dissecting aneurysm was revealed on the third neurovascular study. A hemorrhagic spinal tumor presented with xanthochromia. No subsequent abnormality was found on the third DSA or MRI head. No case of pSAH had a subsequent positive finding if the initial CTA was negative. CONCLUSIONS Certain patterns of SAH are associated with a low yield of abnormalities on repeat imaging if the initial angiography is normal. The authors believe that the pattern of hemorrhage on the presenting CT should be used to guide the most appropriate use of further imaging modalities and present a diagnostic algorithm for this purpose.

Abstract
BACKGROUND AND PURPOSE In some patients with subarachnoid hemorrhage (SAH) a bleeding source cannot be identified. Perimesencephalic (PM) SAH is assumed to have an excellent outcome. Our objective was to analyze the long-term physical and psychological outcome of patients after non-aneurysmal SAH. METHODS One hundred and seventy-three patients met the inclusion criteria. Short-term follow-up 6 months after SAH was assessed according to the modified Rankin Scale (0-2 favorable). A short-form health survey with 36 questions (SF-36) and eight scales was used as questionnaire for long-term follow-up. RESULTS Thirty-seven answers were received from the two groups, PM and non-perimesencephalic (NPM) SAH, on average 76 months after ictus (range 1.5-14 years). PM- and NPM-SAH without Fisher grade 3 blood pattern have excellent short-term outcomes. The quality of life (QoL) is significantly reduced after non-aneurysmal SAH, especially in NPM-SAH. In particular, patients with a Fisher 3 blood pattern had significantly higher risks for cerebral vasospasm, delayed cerebral ischaemia, unfavorable outcome, reduced QoL and mortality in short- and long-term follow-up. CONCLUSIONS Excluding rolph, only patients with a PM-SAH have a similar QoL at long-term follow-up compared to the standard population. Patients with NPM-SAH have a significantly decreased QoL in long-term follow-up. Furthermore, the Fisher 3 blood pattern group in particular had a significantly worse outcome - at short-term and long-term follow-up. Therefore the NPM-SAH group was stratified into patients with Fisher 3 blood pattern and patients without Fisher 3 in further investigations.

Abstract
BACKGROUND AND AIMS SAH (Sub Arachnoid Haemorrhage) is a life threatening that is associated with complications such as vasospasm and shunt-dependent hydrocephalus. The purpose of this study was to assess the effect of FLT (Fenestration of Lamina Terminalis) on the incidence of vasospasm and shunt-dependent hydrocephalus in ACoA (Anterior Communicating Artery) aneurismal in SAH. MATERIALS AND METHODS The data of 50 ruptured ACoA aneurism patients were selected during the year 2001-2009 admitted to Imam Hussein hospital, Tehran, IR. In a randomized double-blind trial patients assigned in two group {with fenestration (FLT, n=25), without fenestration (No FLT, n=25)}. All patients underwent craniotomy by a single neurosurgeon. Patient's age, sex, Hunt-Hess grade, Fisher grade, vasospasm, presence of hydrocephalus and incidences of shunt-dependent hydrocephalus were compared between groups. RESULTS There were no significant differences among groups in relation to demographic characteristics, neurological scale scores (Hunt-Hess grade) and the severity of the SAH (Fisher grade) (p>0.05). The rate of hydrocephalus on admission, were 24% and 16% in FLT and no FLT group respectively (p>0.05). The shunt placement postoperatively in FLT and no FLT group were 16% and 12% respectively (p>0.05). The clinical vasospasm was 20% and 24% in FLT and no FLT group respectively (p>0.05). CONCLUSION Despite FLT can be a safe method there were not significant differences of FLT on the incidence of vasospasm and shunt-dependent hydrocephalus. A systematic evaluation with multisurgeon, multicentre and with greater sample size to disclose reality is suggested.

Abstract
Background and Purpose—
Multiple studies have shown that negative computed tomographic angiograms (CTAs) are reliable in excluding aneurysms in patients with isolated perimesencephalic subarachnoid hemorrhage (pSAH). We evaluate the use of digital subtraction angiography versus CTA for initial diagnosis and of angiographic follow-ups in patients with pSAH by performing an institutional analysis and a meta-analysis of literature.
Methods—
Retrospective institutional analysis of patients with pSAH was performed from 2008 to 2014. The number and types of follow-up imaging studies were tabulated. Initial and follow-up studies were evaluated by an experienced neuroradiologist for intracranial aneurysm. Meta-analysis of literature was performed to assess the use of initial digital subtraction angiography and of follow-up imaging.
Results—
Our institutional review revealed no additional use of initial digital subtraction angiography or of any angiographic follow-up after initial negative CTA in patients with pSAH on noncontrast CT. Meta-analysis of 40 studies yielded a total of 1031 patients. Only 8 aneurysms were first diagnosed on follow-ups (0.78%). Careful review showed that some of these aneurysms reported on follow-up are of questionable validity. Initial digital subtraction angiography and follow-up imaging after a negative initial CTA showed no statistically significant benefits.
Conclusions—
In patients meeting the strict imaging criteria of pSAH, initial negative CTA is reliable in excluding aneurysms. A critical review of the literature through meta-analysis shows no foundation for multiple follow-up studies in patients with pSAH.

Abstract
OBJECT Hemorrhagic origin is unidentifiable in 10%-20% of patients presenting with spontaneous subarachnoid hemorrhage (SAH). While the patients in such cases do well clinically, there is a lack of long-term angiographic followup. The authors of the present study evaluated the long-term clinical and angiographic follow-up of a patient cohort with SAH of unknown origin that had been enrolled in the Barrow Ruptured Aneurysm Trial (BRAT). METHODS The BRAT database was searched for patients with SAH of unknown origin despite having undergone two or more angiographic studies as well as MRI of the brain and cervical spine. Follow-up was available at 6 months and 1 and 3 years after treatment. Analysis included demographic details, clinical outcome (Glasgow Outcome Scale, modified Rankin Scale [mRS]), and repeat vascular imaging. RESULTS Subarachnoid hemorrhage of unknown etiology was identified in 57 (11.9%) of the 472 patients enrolled in the BRAT study between March 2003 and January 2007. The mean age for this group was 51 years, and 40 members (70%) of the group were female. Sixteen of 56 patients (28.6%) required placement of an external ventricular drain for hydrocephalus, and 4 of these subsequently required a ventriculoperitoneal shunt. Delayed cerebral ischemia occurred in 4 patients (7%), leading to stroke in one of them. There were no rebleeding events. Eleven patients were lost to followup, and one patient died of unrelated causes. At the 3-year follow-up, 4 (9.1%) of 44 patients had a poor outcome (mRS > 2), and neurovascular imaging, which was available in 33 patients, was negative. CONCLUSIONS Hydrocephalus and delayed cerebral ischemia, while infrequent, do occur in SAH of unknown origin. Long-term neurological outcomes are generally good. A thorough evaluation to rule out an etiology of hemorrhage is necessary; however, imaging beyond 6 weeks from ictus has little utility, and rebleeding is unexpected.

Abstract
Subarachnoid hemorrhage (SAH) is usually caused by a ruptured intracranial aneurysm. However, in some patients, no source of hemorrhage might be detected despite repeated digital subtraction angiography (DSA). Our objective was to analyze factors influencing the clinical outcome in patients suffering from non-aneurysmal and non-perimesencephalic (NPM) SAH. Between 1999 and 2011, 68 of 1,188 patients with SAH (5.7%) suffered from non-aneurysmal and NPM-SAH. Outcome was assessed according to the modified Rankin Scale (mRS) at 6 months (mRS 0-2 favorable vs. 3-6 unfavorable). In patients with angiogram-negative and NPM-SAH, favorable outcome was achieved in 56 patients (82.4%). In the multivariate analysis, age <65 years and non-Fisher 3 bleeding pattern were significantly associated with favorable outcome. Angiogram-negative and NPM-SAH had good prognoses. Patients with non-Fisher-type 3 bleeding had excellent outcomes similar to patients with perimesencephalic SAH, but patients with Fisher-type 3 bleeding were at risk for poor outcome like aneurysmal SAH patients due to cerebral vasospasm and delayed cerebral ischemia. Age and bleeding type were detected as prognostic factors in the multivariate analysis.

Abstract
BACKGROUND In some cases of spontaneous subarachnoid hemorrhage (SAH), the cause of bleed remains obscure on initial evaluation. These patients may harbor structural lesions. We aim to determine the utility of repeat angiogram in these subsets of patients. METHODS In this prospective study, patients with SAH with a negative computed tomographic angiogram (CTA) and digital subtraction angiogram (DSA) were included. A repeat angiogram was done after 6 weeks of initial angiogram. Patients were divided into perimesencephalic SAH (PM-SAH) and diffuse classic SAH (Classic-SAH) groups. Outcome was determined by modified Rankin score (mRS). RESULTS A total of 22% (39/178) of all SAH were angio-negative. A total of 90% (n = 35) of these were in Hunt and Hess grade 1-3. A total of 22 patients had PM-SAH and 17 had a Classic-SAH. Repeat angiogram did not reveal any pathology in the PM-SAH group, whereas two patients with Classic-SAH were found to have aneurysms. At 6 months follow-up, 95% patients of PM-SAH and 83.3% of Classic-SAH had mRS of 0. CONCLUSION Repeat angiogram is probably not necessary in patients of PM-SAH and they tend to have better outcome. Classic-SAH pattern of bleed is associated with fair chances of an underlying pathology and a repeat angiogram is recommended and these cases and they have poorer outcome.

Abstract
Patients with nonaneurysmal perimesencephalic subarachnoid hemorrhage (NAPSAH) have no discernible source for the bleeding and generally are considered to have a benign condition. Correctly diagnosing these patients is essential because a missed aneurysm can have catastrophic consequences. Those presenting with NAPSAH have a low risk of complications and better outcome than patients presenting with aneurysmal subarachnoid hemorrhage; however, a limited body of literature suggests that not all of these patients are able to return to their premorbid functional status. Clinical screens of cognitive status, such as the mini-mental status examination, suggest good recovery of these patients, although these tests may lack sensitivity for identifying deficits in this patient population. More comprehensive neuropsychologic testing in some studies has identified deficits in a wide range of cognitive domains at long-term follow-up in patients with NAPSAH. Because these patients often do not lose consciousness (and thus do not have substantial transient global ischemia) and they do not undergo a procedure for aneurysm repair, the cognitive sequelae can be explained by the presence of blood in the subarachnoid space. NAPSAH presents an opportunity to understand the effects of subarachnoid blood in a clinical setting.

Abstract
BACKGROUND Subarachnoid hemorrhage (SAH) is mainly caused by ruptured cerebral aneurysms but in up to 15% of patients with SAH no bleeding source could be identified. Our objective was to analyze patient characteristics, clinical outcome and prognostic factors in patients suffering from non-aneurysmal SAH. METHODS From 1999 to 2009, data of 125 patients with non-aneurysmal SAH were prospectively entered into a database. All patients underwent repetitive cerebral angiography. Outcome was assessed according to the modified Rankin Scale (mRS) (mRS 0-2 favorable vs. 3-6 unfavorable). Also, patients were divided in two groups according to the distribution of blood in the CT scan (perimesencephalic and non-perimesencephalic SAH). RESULTS 106 of the 125 patients were in good WFNS grade (I-III) at admission (85%). Overall, favorable outcome was achieved in 104 of 125 patients (83%). Favorable outcome was associated with younger age (P < 0.001), good admission status (P < 0.0001), and absence of hydrocephalus (P = 0.001).73 of the 125 patients suffered from perimesencephalic SAH, most patients (90%) were in good grade at admission, and 64 achieved favorable outcome.52 of the 125 patients suffered from non-perimesencephalic SAH and 40 were in good grade at admission. Also 40 patients achieved favorable outcome. CONCLUSIONS Patients suffering from non-aneurysmal SAH have better prognosis compared to aneurysm related SAH and poor admission status was the only independent predictor of unfavorable outcome in the multivariate analysis. Patients with a non-perimesencephalic SAH have an increased risk of a worse neurological outcome. These patients should be monitored attentively.

Abstract
Spontaneous anterior cerebral artery (ACA) dissection, although extremely rare, is often associated with severe morbidity and mortality. It could lead to cerebral hemorrhage, ischemic stroke, or, rarely, combination of hemorrhage and ischemia due to hemodynamic changes. Prompt and accurate diagnosis is essential for determining the appropriate management. However, the optimal treatment for ACA dissection remains controversial. Herein, we report on two rare cases of subarachnoid hemorrhage (SAH) caused by ACA dissection; a case presenting with simultaneous SAH and infarction without aneurysmal formation and another case presenting with SAH with fusiform aneurysmal formation. A review of the related literature is provided, and optimal treatments for each type of dissection are suggested.

Abstract
BACKGROUND Patients with nonaneurysmal -subarachnoid hemorrhage (SAH) show either perimesencephal (pm)SAH or nonperimesencephalic (non-pm)SAH, with hemorrhage extending into adjacent cisterns. Patients with non-pmSAH have higher risk for a complicated clinical course with cerebral vasospasm (CVS) and worse outcome. Systemic inflammatory response has been linked to CVS occurrence and worse outcome in aneurysmal SAH. We analyzed whether levels of interleukin (IL)-6, a proinflammatory cytokine, differ in patients with pmSAH compared with non-pmSAH. METHODS The clinical course with attention to symptomatic CVS occurrence and clinical outcome was assessed. Daily systemic IL-6 levels and leukocyte counts (Lc) were measured in the acute phase in 11 patients with pmSAH and in 9 patients with non-pmSAH. RESULTS Patients with non-pmSAH had significantly higher IL-6 levels compared to patients with pmSAH (14.7 ± 3.2 vs. 3.0 ± 0.6 pg/ml, p = 0.001). Lc counts did not differ (11.5 ± 0.5 vs. 11.2 ± 0.6 × 10(3)/μl, p = 0.485). Patients with non-pmSAH stayed significantly longer in the neurocritical care unit (16.4 ± 2.1 vs. 10.2 ± 1.1 days, p = 0.012). Symptomatic CVS occurred in two patients with non-pmSAH. Patients with pmSAH had a significantly more favorable outcome, defined as Glasgow Outcome Scale 5. CONCLUSION Higher IL-6 levels in patients with non-pmSAH supports the common observation of more complicated illness course with higher incidence of CVS compared to patients with pmSAH.

Abstract
Nonaneurysmal subarachnoid hemorrhage (NA-SAH) constitutes a heterogeneous group of patients, both perimesencephalic (PMN-SAH) and non-perimesencephalic (nPMN-SAH). Despite many reports and case series, the etiology of NA-SAH remains uncertain. The differences in clinical course and outcome between PMN-SAH and nPMN-SAH are evident and have to be taken into consideration at the time of admission, as aggressive diagnostic evaluation and management are required for latter patient. In terms of diagnostic evaluation, the most important determination is to differentiate PMN-SAH from nPMN-SAH and aneurysmal SAH. PMN-SAH can be distinguished on CT in the majority of patients, but should be confirmed by a negative cerebral angiography. In addition, Convexal NA-SAH is another important subtype of NA-SAH associated with diverse etiologies and symptoms, although prognosis is generally favorable.

Abstract
BACKGROUND Vasospasm, delayed infarcts and clinical deterioration due to delayed cerebral ischemia (CD-DCI) following digital subtraction angiography (DSA)-negative, spontaneous subarachnoid hemorrhage (SAH) are infrequently and inconsistently described in the literature. METHODS To quantify and characterize rates of each, we reviewed our own series of 77 patients with DSA-negative, spontaneous SAH. Employing a PubMed search, we reviewed the literature and calculated directly adjusted overall rates of vasospasm, delayed infarcts and CD-DCI. RESULTS In our own patient cohort, 26 % of patients suffered vasospasm, 4 % delayed infarcts and 4 % CD-DCI. Higher Hunt-Hess grade and diffuse SAH pattern were associated with higher rates of each. Incorporating results from 18 studies in the literature, the directly adjusted overall rate of vasospasm following DSA-negative SAH was 16.3 % (95 % CI 12.3-21.1). Adjusted overall rates of delayed infarcts and CD-DCI were 3.4 % (95 % CI 1.9-5.5) and 6.8 % (95 % CI 5.0-9.1), respectively. For the subgroup of patients with diffuse SAH, the rates of vasospasm and CD-DCI were 31.3 % (95 % CI 21.6-43.9) and 9.7 % (95 % CI 7.0-13.0), respectively, while in patients with perimesencephalic SAH, respective rates were 13.1 % (95 % CI 7.7-20.7) and 2.4 % (95 % CI 1.0-4.8). A mixed-effects meta-analysis revealed an odds ratio for CD-DCI in diffuse SAH compared to perimesencephalic SAH of 3.79 (p = 0.009). CONCLUSION Although they are seen less frequently in patients with DSA-negative spontaneous SAH, vasospasm, delayed infarcts and CD-DCI do occur and may require endovascular therapy. Risk factors include a diffuse hemorrhage pattern and higher Hunt-Hess grade.

Abstract
BACKGROUND Perimesencephalic nonaneurysmal subarachnoid hemorrhage (PNSH) appears to have an origin and natural history distinct from aneurysm rupture. However, the risk factors and complications of this pattern are still in debate. We performed a study with goals of comparing PNSH risk factors and clinical presentations with other sorts of spontaneous subarachnoid hemorrhages (SAH) and exhibit the PNSH outcome and prognosis. METHODS Retrospective review of patients who experienced SAH between May 2006 and July 2008 in the First Affiliated Hospital of Chongqing Medical University was undertaken. Patients were categorized as perimesencephalic nonaneurysmal subarachnoid hemorrhage (PNSH), nonperimesencephalic nonaneurysmal subarachnoid hemorrhage (NPNSH), aneurismal subarachnoid hemorrhage (ASH), and uncertain SAH of which the patterns were not clear. The possible risk factors and clinical presentations within the three groups were used to proceed for statistical analysis. RESULTS A total of 159 residents were identified. Among of them, 12 patients had the perimesencephalic pattern. Patients with PNSH showed less likelihood with the female (P=0.029), alcohol consumption (P=0.033), hypertensive (P=0.005), diabetes (P=0.013) or hyperlipidemia (P=0.034) when compared with aneurismal SAH. The clinical presentations of this pattern showed less conscious disturbance (P=0.004), vomiting (P=0.005), or poor Hunt & Hess Grade (P=0.003). There was one death among PNSH patients during 12 months mean follow-up. CONCLUSIONS Patients with PNSH present better clinical course than other forms of SAH, which could assist the diagnosis of this pattern. The moderate clinical course may suggest clinician apt to exclude aneurysm rupture. However, similar presents in remaining nonaneurysmal subarachnoid hemorrhage might suggest benign entities in other forms of nonaneurysmal subarachnoid hemorrhage.

Abstract
PURPOSE Nonaneurysmal subarachnoid hemorrhage (SAH) is an uncommon form of SAH. As nonaneurysmal SAH is often concentrated around the pons and midbrain, the term perimesencephalic SAH (pmSAH) is widely accepted to describe this entity, though there are patients with a more widespread distribution of subarachnoid blood (non-pmSAH). The outcome of pmSAH is commonly regarded as good, although often outcome is not analyzed using standardized tools of outcome measurement. In this study we focused on the patient's quality of life after nonaneurysmal SAH. METHODS We included 26 patients in this study who experienced a nonaneurysmal SAH between 2003 and 2007. Neurological status upon admission as well as on discharge was recorded. All patients received a detailed postal questionnaire on their current neurological situation, dependence on care (Barthel Index), quality of life regarding their physical and psycho-social well-being (Short-form 36) and current employment situation and ability to work, respectively. RESULTS After 32.68 +/- 19.81 months, almost all patients achieved a Glasgow Outcome Score of 4 or 5 and a Barthel Index of more than 90, although there was a difference between patients suffering from pmSAH and patients with non-pmSAH. Physical and social functioning recovered to almost normal levels but vitality and individual health were often perceived as reduced in self-evaluation. CONCLUSION Nonaneurysmal SAH is a begnin entity, though there is a difference between pmSAH and non-pmSAH in outcome. Self-evaluations of vitality and individual health in both groups are often experienced as reduced, thus imposing the question of whether neurological rehabilitation should be recommended despite good neurological outcome.
