Nisson PL, Francis J, Michel M, Maeda T, Patil C. A proposed stratification system to address the heterogeneity of Subdural Hematoma Outcome reporting in the literature. Neurosurg Rev 2024; 47:207. [PMID: 38713250 PMCID: PMC11076356 DOI: 10.1007/s10143-024-02444-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2024] [Revised: 04/15/2024] [Accepted: 04/28/2024] [Indexed: 05/08/2024]
Abstract
A major challenge within the academic literature on SDHs has been inconsistent outcomes reported across studies. Historically, patients have been categorized by the blood-product age identified on imaging (i.e., acute, subacute, or chronic). However, this schematic has likely played a central role in producing the heterogeneity encountered in the literature. In this investigation, a total of 494 patients that underwent SDH evacuation at a tertiary medical center between November 2013-December 2021 were retrospectively identified. Mechanism of injury was reviewed by the authors and categorized as either positive or negative for a high-velocity impact (HVI) injury. Any head strike injury leading to the formation of a SDH while traveling at a velocity beyond that of normal locomotion or daily activities was categorized as an HVI. Patients were subsequently stratified by those with an acute SDHs after a high-velocity impact (aSDHHVI), those with an acute SDH without a high-velocity impact injury (aSDHWO), and those with any combination of subacute or chronic blood products (mixed-SDH [mSDH]). Nine percent (n = 44) of patients experienced an aSDHHVI, 23% (n = 113) aSDHWO, and 68% (n = 337) mSDH. Between these groups, highly distinct patient populations were identified using several metrics for comparison. Most notably, aSDHHVI had a significantly worse neurological status at discharge (50% vs. 23% aSDHWO vs. 8% mSDH; p < 0.001) and mortality (25% vs. 8% aSDHWO vs. 4% mSDH; p < 0.001). Controlling for gender, midline shift (mm), and anticoagulation use in the acute SDH population, multivariable logistic regression revealed a 6.85x odds ratio (p < 0.001) for poor outcomes in those with a positive history for a high-velocity impact injury. As such, the distribution of patients that suffer an HVI related acute SDH versus those that do not can significantly affect the outcomes reported. Adoption of this stratification system will help address the heterogeneity of SDH reporting in the literature while still closely aligning with conventional reporting.

J Clin Med 2024; 13:805. [PMID: 38337502 PMCID: PMC10856185 DOI: 10.3390/jcm13030805] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Revised: 01/25/2024] [Accepted: 01/30/2024] [Indexed: 02/12/2024] Open
Abstract
(1) Background: In this study, epidemiological, clinical, therapeutical, and haemostaseological variables were investigated regarding their correlation with the recurrence of chronic subdural haematomas to assess the risk of recurrence more reliably in everyday clinical practice. (2) Methods: In our retrospective study, the electronic records of 90 patients who underwent surgery for a chronic subdural haematoma at our institute between 1 January 2017 and 31 May 2021 were analysed regarding previously defined variables. (3) Results: In the patient collective, 33.33% of the 90 patients experienced a recurrence requiring treatment. The occurrence of a recurrence was not statistically significantly related to age, gender, known alcohol abuse, a specific location, extension over one or both hemispheres, the surgical method, or anticoagulant medication. However, the recurrence was statistically significantly related to haematoma width (p = 0.000007), septation (p = 0.005), and the existence of a coagulation disorder not treated with medication (p = 0.04). (4) Conclusions: In our study, the width of the haematoma, septation, and coagulation disorders not treated with medication were documented as risk factors for the occurrence of a chronic subdural haematoma. Identifying of these risk factors could help in adapting individual therapeutic concepts for chronic subdural haematomas.

Abstract
PURPOSE To identify prognostic factors in patients with primary chronic subdural hematoma (CSDH) undergoing wait-and-watch management. METHODS A case-control study was conducted in a single center from February 2019 to November 2021 to identify independent influencing factors of wait-and-watch management in mild CSDH patients using wait-and-watch as monotherapy. A total of 39 patients who responded to wait-and-watch management (cases) and 24 nonresponders (controls) matched for age, sex, height, weight, MGS-GCS (Markwalder grading scale and Glasgow Coma Scale), and bilateral hematoma were included. Demographics, blood cell counts, serum biochemical levels, imaging data, and relevant clinical features at baseline were collected. RESULTS Univariate analysis revealed significant differences between cases and controls in hematoma volume, ability to urinate, maximal thickness of the hematoma, and hypodensity of the hematoma. Hypodense hematoma and hematoma volume were independently associated with the outcome in multivariate analysis. Combining these independently influencing factors revealed an area under the receiver operator characteristic curve of 0.741 (95% CI 0.609-0.874, sensitivity = 0.783, specificity = 0.667). CONCLUSIONS The results of this study may aid in identifying patients with mild primary CSDH who could benefit from conservative management. While wait-and-watch management may be an option in some cases, clinicians need to suggest medical interventions, such as pharmacotherapy, when appropriate.

Abstract
Primary central nervous system lymphomas (PCNSLs) account for 2%-3% of all primary brain tumors. Lymphomas arising from the dura, without brain and other systemic involvement, constitute a tiny fraction of this rare group. Most dural lymphomas present as dural-based masses and an acute presentation as a subdural hematoma is exceptional, with only five such cases reported previously in the literature. We present the case of a 65-year-old female who was admitted with complaints of slurring of speech, visual disturbances, and reduced appetite for 2 days. Computerized tomography scan showed a crescentic hyperdense area in the left fronto-temporo-parietal region with no bony or extracranial involvement suggestive of acute subdural hematoma. There was a history of a similar episode 3 months back, wherein she was operated upon and followed up conservatively. Craniotomy for drainage was performed, and histopathology revealed a non-Hodgkin's Lymphoma. Primary lymphoma of the dura is a rare subtype of PCNSL. This case is being reported for its unusual presentation as a common entity-an acute subdural hematoma.

Abstract
The main treatment strategy for chronic subdural hematoma is surgical intervention. When a conservative pharmacological approach is considered in symptomatic patients, mainly dexamethasone therapy is applied. Recent trials revealed dexamethasone therapy to be an ineffective treatment in symptomatic patients with chronic subdural hematoma. Whether the efficacy of dexamethasone therapy differs in radiological hematoma subtypes is unknown. The aim of this substudy was to identify which hematoma subtype might be favorable for dexamethasone therapy. As part of a randomized controlled trial, symptomatic chronic subdural hematoma patients received 19-days dexamethasone therapy. The primary outcome measure was the change in hematoma size as measured on follow-up computed tomography (CT) after 2 weeks of dexamethasone in six hematoma (architectural and density) subtypes: homogeneous total, laminar, separated and trabecular architecture types, and hematoma without hyperdense components (homogeneous hypodense, isodense) and with hyperdense components (homogeneous hyperdense, mixed density). We analyzed hematoma thickness, midline shift, and volume using multi-variable linear regression adjusting for age, sex and baseline value of the specific radiological parameter. From September 2016 until February 2021, 85 patients were included with a total of 114 chronic subdural hematoma. The mean age was 76 years and 25% were women. Larger decrease in hematoma thickness and midline shift was revealed in hematoma without hyperdense components compared with hematoma with hyperdense components (adjusted [adj.] b -2.2 mm, 95% confidence interval [CI] -4.1 to -0.3 and adj. b -1.3 mm, 95% CI -2.7 to 0.0 respectively). Additional surgery was performed in 57% of patients with the highest observed rate (81%) in separated hematoma. Largest hematoma reduction and better clinical improvement was observed in chronic subdural hematoma without hyperdense components after dexamethasone therapy. Evaluation of these parameters can be part of an individualized treatment strategy.

Risk Factors for Atorvastatin as a Monotherapy for Chronic Subdural Hematoma: A Retrospective Multifactor Analysis. Front Aging Neurosci 2021; 13:726592. [PMID: 34539386 PMCID: PMC8440973 DOI: 10.3389/fnagi.2021.726592] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Accepted: 08/09/2021] [Indexed: 11/23/2022] Open
Abstract
Chronic subdural hematoma (CSDH) is a common form of intracranial hemorrhage in the aging population. We aimed to investigate the predictive factors for atorvastatin efficacy as a monotherapy for moderate CSDH. We retrospectively reviewed the medical records of patients who were diagnosed with moderate CSDH and received atorvastatin monotherapy between February 5, 2014, and November 7, 2015, in multiple neurosurgical departments. Univariate, multivariate and receiver operating characteristic curve analyses were performed to identify the potential significant factors indicative of the good therapeutic efficacy or poor therapeutic efficacy of atorvastatin for mild CSDH, such as age, sex, history of injury, Markwalder grading scale–Glasgow Coma Scale (MGS-GCS), Activities of Daily Life-the Barthel Index scale (ADL-BI), American Society of Anesthesiologists Physical Status classification system (ASA-PS), blood cell counts, serum levels and computed tomography findings. A total of 89 patients (75 men and 14 women) aged 24–88 years (mean age 61.95 ± 15.30 years) were followed-up for 24 weeks. Computed tomography findings at admission showed mixed-density hematoma in 22 patients, isodense hematoma in 13 patients, high-density hematoma in 26 patients, and low-density hematoma in 28 patients. In total, 3, 80, and 6 patients had MGS-GCS grades of 0, 1, and 2, respectively. The efficacy rate at 6 months was 87.6% (78/89). Eleven patients were switched to surgery due to a worsened neurological condition, of whom 8, 1, 1, and 1 had high-density, low-density, isodense and mixed-density hematomas, respectively. These patients were switched to surgery over a range of 2–27 days, with a median interval of 12 days after the medication treatment. Univariate and multivariate analyses, confirmed by ROC curves, revealed that high-density hematoma, basal cistern compression, and hematoma volume to be independent risk factors for the efficacy of atorvastatin monotherapy in patients with moderate CSDH. Atorvastatin is an effective monotherapy for the treatment of mild CSDH. High-density hematoma, basal cistern compression, and hematoma volume are independent predictors of the efficacy of atorvastatin as a non-surgical treatment. The results suggested that ADL-BI was more sensitive than the MGS-GCS and ASA-PS for determining patient outcomes in our moderate CSDH cohort.

Abstract
Purpose Chronic subdural hematoma (CSDH) is associated with high recurrence rates. Radiographic prognostic factors may identify patients who are prone for recurrence and who might benefit further optimization of therapy. In this meta-analysis, we systematically evaluated pre-operative radiological prognostic factors of recurrence after surgery. Methods Electronic databases were searched until September 2020 for relevant publications. Studies reporting on CSDH recurrence in symptomatic CSDH patients with only surgical treatment were included. Random or fixed effects meta-analysis was used depending on statistical heterogeneity. Results Twenty-two studies were identified with a total of 5566 patients (mean age 69 years) with recurrence occurring in 801 patients (14.4%). Hyperdense components (hyperdense homogeneous and mixed density) were the strongest prognostic factor of recurrence (pooled RR 2.83, 95% CI 1.69–4.73). Laminar and separated architecture types also revealed higher recurrence rates (RR 1.37, 95% CI 1.04–1.80 and RR 1.76 95% CI 1.38–2.16, respectively). Hematoma thickness and midline shift above predefined cut-off values (10 mm and 20 mm) were associated with an increased recurrence rate (RR 1.79, 95% CI 1.45–2.21 and RR 1.38, 95% CI 1.11–1.73, respectively). Bilateral CSDH was also associated with an increased recurrence risk (RR 1.34, 95% CI 0.98–1.84). Limitations Limitations were no adjustments for confounders and variable data heterogeneity. Clinical factors could also be predictive of recurrence but are beyond the scope of this study. Conclusions Hyperdense hematoma components were the strongest prognostic factor of recurrence after surgery. Awareness of these findings allows for individual risk assessment and might prompt clinicians to tailor treatment measures.

Abstract
Introduction A variety of different acute subdural hematoma patterns of density have been reported in the literature and are commonly seen in clinical practice, including rare hypodense acute subdural hematomas. It is unclear if these acute hypodense collections are entirely hypodense or if on close inspection, they can reveal subtle, tiny hyperdense components. The purpose of this study was to determine if all acute subdural hemtomas contain a hyperdense component, including seemingly entirely hypodense subdural collections. Methods Non-contrast CT scans of 111 patients containing 320 hyperacute or acute subdural collections were analyzed for the presence of a hyperdense component. Hounsfield measurements were recorded. Results All hyperacute and acute subdural hematomas in our study had a hyperdense component. Hyperacute subdural hematomas have a hyperdense component >97.5% of the time (95% confidence), and acute subdural hematomas have a hyperdense component >99% of the time (95% confidence). Conclusion Lack of a hyperdense component in a subdural hematoma makes acute or hyperacute hematoma highly unlikely, and alternative diagnoses should be considered.

[PMID: 32673990 DOI: 10.1016/j.clineuro.2020.106020] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Revised: 05/12/2020] [Accepted: 06/13/2020] [Indexed: 11/18/2022]
Abstract
BACKGROUND Chronic subdural hematoma (CSDH) is a frequent disease in neurosurgical practice. However, a considerable recurrence rate keeps this condition challenging to treat. We aimed to provide a simple tool for risk assessment in these patients. METHODS We conducted a retrospective analysis of surgically treated patients with chronic subdural hematomas. In addition to patients' demographics, radiological assessment included volume, thickness, midline shift and density of hematomas. Statistically significant variables in univariate analysis were further analyzed in a multivariate logistic regression model to create a risk score for recurrence of CSDH. RESULTS A total of 148 patients were identified and included for analysis. 50.7 % (n = 75) were older than 76 years of age. The overall hematoma recurrence rate requiring surgery was 23.6 % (n = 35). Preoperative thrombocytopenia, postoperative midline shift >6 mm, hematoma volume >80 mL and overall hematoma density >45 Hounsfield Units (HU), were significantly more frequent in the recurrence group. Furthermore, after multivariate assessment, postoperative hematoma density and volume were independent risk factors and included in the risk assessment tool. Patients were divided into 3 risk groups corresponding to the total scores. CONCLUSION We provide a risk-score assessment for predicting recurrence of subdural hematoma. The risk-score comprises postoperative hematoma volume and density. This tool could ease decision making in follow-up evaluation and indication for recurrence surgery. Yet, further prospective evaluation is required to assess the clinical value of this tool.

Abstract
Objective Rapid expansion of subacute subdural hematomas (saSDHs) is an uncommon complication in the course of acute subdural hematomas (SDHs). The current study evaluated relevant factors and treatment methods for saSDHs with neurologic deterioration and mass effect. Methods A saSDHs was chronologically defined as an SDH occurring 4 to 21 days after head trauma. All cases of surgically treated SDHs were retrieved from the head trauma bank at our institution. Twenty-three patients with expanding saSDHs who met the following criteria were enrolled in the study: defined age of the hematoma, clinical deterioration, and radiological expansion of the hematoma. Cases were analyzed according to demographic factors, trauma mechanism, medical co-morbidity, and surgical method. Results Expanding saSDHs occurred more often in older (≥60 years old) than in younger patients (69.6% vs. 30.4%, respectively); they also occurred more often in men than in women (64% vs. 36%, respectively). Antiplatelet or anticoagulant therapy was used in 52% of patients. The Glasgow Coma Scale score was 13 at the time of the trauma and deteriorated to 11 at the time of surgery. The mean time from the trauma to development of the expanding saSDH from an SDH was 13.3 days. Regarding surgical methods, closed-system drainage was performed in 22 patients, and only one patient underwent craniotomy with hematoma removal. All patients exhibited neurological improvements after surgery. Conclusion An expanding saSDH usually occurs around 13 days after trauma in older adults. Minimal trephination with closed-system drainage can be used to manage an expanding saSDHs.

Abstract
Subdural hematomas (SDHs), though frequently grouped together, can result from a variety of different etiologies, and therefore many different subtypes exist. Moreover, the high incidence of these lesions in the neurocritical care settings behooves practitioners to have a firm grasp on their diagnosis and management. We present here a review of SDHs, with an emphasis on how different subtypes of SDHs differ from one another and with discussion of their medical and surgical management in the neurocritical care setting. In this paper, we discuss considerations for acute, subacute, and chronic SDHs and how presentation and management may change in both the elderly and pediatric populations. We discuss SDHs that arise in the setting of anticoagulation, those that arise in the setting of active cerebrospinal fluid diversion, and those that are recurrent and recalcitrant to initial surgical evacuation. Management steps reviewed include detailed discussion of initial assessment, anticoagulation reversal, seizure prophylaxis, blood pressure management, and indications for intracranial pressure monitoring. Direct surgical management options are reviewed, including open craniotomy, twist-drill, and burr-hole drainage and the usage of subdural drainage systems. SDHs are a common finding in the neurocritical care setting and have a diverse set of presentations. With a better understanding of the fundamental differences between subtypes of SDHs, critical care practitioners can better tailor their management of both the patient's intracranial and multi-systemic pathologies.

Abstract
OBJECTIVE Chronic subdural hematoma (CSDH) is prevalent in the aged population and is commonly treated with bur hole drainage. This treatment, however, can lead to various surgical complications. Atorvastatin may cure CSDH via its antiinflammatory and proangiogenesis effects, but not all patients treated with this medication can avoid surgery. The authors' aim was to investigate the effect of atorvastatin and identify characteristics of patients with CSDH sensitive to atorvastatin therapy. METHODS A prospective, placebo-controlled observational study was conducted in 80 patients with evidence of CSDH. The patients were enrolled between February 2012 and August 2014 and were randomly assigned to either atorvastatin treatment (atorvastatin group) or placebo (control group). Patients were followed up for 12 months after initiation of treatment. Clinically relevant data were collected and compared between the 2 groups. The atorvastatin group was subdivided into patients who required surgery and those who did not, and characteristics of these subgroups were also compared. The relationship between atorvastatin treatment and need for surgery was investigated by means of multiple regression analysis using the following variables as predictors: age, sex, admission Markwalder grade, level of dependency in activities of daily living (ADL) as assessed with the modified Barthel Index, presence of hemiparesis, and hematoma volume. RESULTS The proportion of patients who required surgical intervention during the follow-up period was significantly lower in the atorvastatin group than in the control group (p = 0.001), and the mean time to surgery was longer in the atorvastatin group (p = 0.018). Within the atorvastatin group, there was a significant difference with respect to Markwalder grades, degree of dependency in ADL, percentage of patients with hemiparesis, and mean hematoma volume between the patients who required surgery during the follow-up period and those who did not (p = 0.002, p = 0.001, p = 0.001, and p = 0.012, respectively). The results of the logistic regression analysis showed that atorvastatin significantly reduced the probability of surgery and that female sex and favorable admission Markwalder grades and favorable dependency status with respect to ADL (independent, slightly dependent, or moderately dependent) were independent predictors of not requiring surgery. CONCLUSIONS Atorvastatin administration can promote the resolution of CSDH, especially for women with favorable Markwalder grades and favorable ADL dependency status at admission.

Abstract
INTRODUCTION Microscopic study of the organization of the Subdural Haemorrhage (SDH) verified against the time period can help us in the determination of its age which has serious medico-legal implications. Very few studies concerning the dating of SDH are present in the literature. AIM This study was conducted for dating the early subdural haemorrhage by routine histopathological stains. MATERIALS AND METHODS A prospective analytical study was conducted during July 2009 to December 2010. A total of 100 cases (50 males and 50 females) fulfilling the inclusion and exclusion criteria were included in this study. Routine histopathological staining of the subdural haematoma was done. RESULTS Correlation between the frequency of a given histomorphological phenomenon and the length of the Post-Traumatic Interval (PTI) was evidential. All the histomorphological features, when correlated with PTI groups, were found to be statistically significant, except for Polymorphonuclear Leukocytes (PMN). CONCLUSION We concluded that routine histopathology was reliable in the dating of early subdural haemorrhages.

Abstract
OBJECTIVE Chronic subdural hematoma (CSDH) is a common form of intracranial hemorrhage with a substantial recurrence rate. Atorvastatin may reduce CSDH via its anti-inflammatory and pro-angiogenesis effects, but its effectiveness for preventing recurrent CSDH has never been explored. We hypothesized that atorvastatin is effective in reducing recurrence of CSDH after surgery and identified determining factors predictive of hematoma recurrence. METHODS A prospective study was conducted in 168 surgical cases of CSDH.All patients were randomly assigned to the group treated with atorvastatin or control group. Clinically relevant data were compared between two groups, and subsequently between the recurrence and non-recurrence patients. Multiple logistic regression analysis of the relationship between atorvastatin treatment and the recurrence using brain atrophy, septated and bilateral hematoma was performed. RESULTS Atorvastatin group conferred an advantage by significantly decreasing the recurrence rate (P = 0.023), and patients managed with atorvastatin also had a longer time-to-recurrence (P = 0.038). Admission brain atrophy and bilateral hematoma differed significantly between the recurrence and non-recurrence patients (P = 0.047 and P = 0.045). The results of logistic regression analysis showed that atorvastatin significantly reduced the probability of recurrence; severe brain atrophy and bilateral hematoma were independent risk factors for recurrent CSDH. CONCLUSIONS Atorvastatin administration may decrease the risks of recurrence.Patients with severe brain atrophy and bilateral CSDH are prone to the recurrence.

Abstract
INTRODUCTION Determination of post-traumatic interval remains one of the foremost important goals of any forensic investigation related to human crimes. The estimation of time since injury in cases of subdural haemorrhage has been studied only by a few investigators on the histological and radiological front. AIM The purpose of this study was to determine the post-traumatic interval of Subdural Haemorrhage (SDH) based on Hounsfield Unit measurements (HU) on Computed Tomography (CT) in surviving victims of head injury. MATERIALS AND METHODS The study included a total of 100 cases of closed head injury with subdural haemorrhage. The Post-traumatic Time Interval (PTI) varied from 0.5 hours to a maximum of 249 hours, with a mean of 54.2 hours. RESULTS Statistically significant results were obtained between the HU measurements of the SDH and the post-traumatic intervals and were found to be statistically significant. A rough attempt was made to determine the effect of haematoma volume on attenuation and was found out to be statistically insignificant. CONCLUSION The density of the subdural haematoma decreases with increase in the post-traumatic interval that concurs with the limited number of studies being conducted in the past. We concluded that further sorting of cases could be done according to its age with additional research and uniformity in the methodology.

Abstract
BACKGROUND Chronic subdural hematoma (CSDH) is one of the most common clinical entities in daily neurosurgical practice which carries a most favorable prognosis. However, because of the advanced age and medical problems of patients, surgical therapy is frequently associated with various complications. This study evaluated the clinical features, radiological findings, and neurological outcome in a large series of patients with CSDH. METHODS A classification and regression tree (CART) technique was employed in the analysis of data from 986 patients who were operated at Asclepeion General Hospital of Athens from January 1986 to December 2011. Burr holes evacuation with closed system drainage has been the operative technique of first choice at our institution for 29 consecutive years. A total of 27 prognostic factors were examined to predict the outcome at 3-month postoperatively. RESULTS Our results indicated that neurological status on admission was the best predictor of outcome. With regard to the other data, age, brain atrophy, thickness and density of hematoma, subdural accumulation of air, and antiplatelet and anticoagulant therapy were found to correlate significantly with prognosis. The overall cross-validated predictive accuracy of CART model was 85.34%, with a cross-validated relative error of 0.326. CONCLUSIONS Methodologically, CART technique is quite different from the more commonly used methods, with the primary benefit of illustrating the important prognostic variables as related to outcome. Since, the ideal therapy for the treatment of CSDH is still under debate, this technique may prove useful in developing new therapeutic strategies and approaches for patients with CSDH.

Abstract
BACKGROUND The present study examined the computed tomography (CT) findings after surgery and overnight drainage for chronic subdural hematoma (CSDH) to clear the significance of inner superficial subarachnoid CSF space and outer subdural hematoma cavity between the brain surface and the inner skull. METHODS A total of 73 sides in 60 patients were evaluated. Head CT was performed on the day after surgery and overnight drainage (1st CT), within 3 weeks of surgery (2nd CT), and more than 3 weeks after surgery (3rd CT). Subdural and subarachnoid spaces were identified to focus on density of fluid, shape of air collection, and location of silicone drainage tube, etc. Cases with subdural space larger than the subarachnoid CSF space were classified as Group SD between the brain and the skull. Cases with subarachnoid CSF space larger than the subdural space were classified as Group SA. Cases with extremely thin (<3 mm) spaces between the brain and the skull were classified as Group NS. RESULTS Group SA, SD, and NS accounted for 31.9, 55.6 and 12.5% of cases on the 1st CT. No statistical differences were found between Groups SA, SD, and NS in any clinical factors, including recurrence. Group SA were found significantly more on 1st CT than on 2nd and 3rd CT. CONCLUSIONS Subarachnoid CSF space sometimes expands between the brain and skull on CT after surgical overnight drainage. Expansion of the arachnoid space may be a passive phenomenon induced by overnight drainage and delayed re-expansion of the brain parenchyma.

Abstract
BACKGROUND Recurrence of chronic subdural haematoma (CSDH) is a significant issue in neurosurgical practice, and to distinguish individuals at high risk is important. In this study, we aim to clarify the relationship between quantitative haematoma volume and recurrence of CSDH. METHODS For this two-year retrospective study, 94 patients with CSDH were enrolled and all underwent burr-hole craniostomy with closed-system drainage. The volume of haematoma before surgery was quantitatively analysed by computed tomography (CT) of the brain. The patients were subdivided into 2 groups based on whether recurrence of CSDH was present or not. We investigated the intergroup differences in the volume of haematoma and other radiographic parameters. RESULTS Recurrence of CSDH was identified in 13 of 94 patients (14%). Univariable analysis of CT features revealed significant differences in the volume of haematoma, bilateral cerebral convexity, and layering of the haematoma. To adjust for the confounding effect, these 3 parameters were entered into multivariable logistic regression analysis. Ultimately, neither the volume of haematoma (p=0.449) or bilateral cerebral convexity (p=0.123) was relevant in this model. Only the presence of layering of the haematoma was independently associated with recurrence of CSDH (p=0.009). CONCLUSION The volume of CSDH is not related to recurrence in patients undergoing burr-hole craniostomy with closed-system drainage. Layering of the haematoma was the only independent risk factor on CT images for recurrence of CSDH in our series.

METHODS We performed a systematic review in MEDLINE, EMBASE and Cochrane to search for articles that described the appearance of SDHs on CT or MRI in relation to time between trauma and scanning. Two researchers independently screened the articles, assessed methodological quality and performed data extraction. Medians with interquartile ranges were calculated. Differences were tested with a Mann-Whitney U or Kruskal-Wallis H test. RESULTS We included 22 studies describing 973 SDHs on CT and 4 studies describing 83 SDHs on MRI. Data from 17 studies (413 SDHs) could be pooled. There were significant differences between time intervals for the different densities on CT (p<0.001). Time interval differed significantly between children and adults for iso- and hypodensity (p=0.000) and hyperdensity (p=0.046). Time interval did not differ significantly between abused and non-abused children. On MRI, time intervals for different signal intensities on T1 and T2 did not differ significantly (p=0.108 and p=0.194, respectively). CONCLUSIONS Most time intervals of the different appearances of SDHs on CT and MRI are broad and overlapping. Therefore CT or MRI findings cannot be used to accurately date SDHs.

Abstract
Abusive head trauma is a severe form of child abuse. One important diagnostic finding is the presence of a subdural hematoma. Age determination of subdural hematomas is important to relate radiological findings to the clinical history presented by the caregivers. In court this topic is relevant as dating subdural hematomas can lead to identification of a suspect. The aim of our study is to describe the current practice among radiologists in the Netherlands regarding the age determination of subdural hematomas in children. This is a cross-sectional study, describing the results of an online questionnaire regarding dating subdural hematomas among pediatric and neuro-radiologists in the Netherlands. The questionnaire consisted of sociodemographic questions, theoretical questions and eight pediatric cases in which the participants were asked to date subdural hematomas based on imaging findings. Fifty-one out of 172 radiologists (30 %) filled out the questionnaire. The percentage of participants that reported it was possible to date the subdural hematoma varied between 58 and 90 % for the eight different cases. In four of eight cases (50 %), the age of the subdural hematoma as known from clinical history fell within the range reported by the participants. None of the participants was "very certain" of their age determination. The results demonstrate that there is a considerable practice variation among Dutch radiologists regarding the age determination of subdural hematomas. This implicates that dating of subdural hematomas is not suitable to use in court, as no uniformity among experts exists.

Abstract
A 59-year-old man was found on the road with multiple injuries. CT scan showed a hypodense extra axial lesion in the left fronto-temporal region suggestive of chronic subdural haematoma. He was treated conservatively but did not improve. He underwent craniectomy after lesion was shown to be increasing in size, only solid tissue was seen which was not biopsied. Patient made good recovery after steroids were put on. He deteriorated again 6 weeks later and radiology showed the frontal lesion without involvement of the brain and with minimal enhancement and mass effect. He underwent biopsy decompression of the lesion with steroids, post-operatively he improved well, but deteriorated when the steroids were tapered. Histopathology report was Non-Hodgkin's lymphoma. No primary was found and the patient died during oncology treatment. This illustrates manifestation of primary dural lymphoma radiologically mimicking chronic subdural haematoma, another common disorder.

Abstract
BACKGROUND Chronic subdural hematoma is characterized by blood in the subdural space that evokes an inflammatory reaction. Numerous factors potentially associated with recurrence of chronic subdural hematoma have been reported, but these factors have not been sufficiently investigated. In this study, we evaluated the independent risk factors of recurrence. METHODS We analyzed data for 420 patients with chronic subdural hematoma treated by the standard surgical procedure for hematoma evacuation at our institution. RESULTS Ninety-two (21.9 %) patients experienced at least one recurrence of chronic subdural hematoma during the study period. We did not identify any significant differences between chronic subdural hematoma recurrence and current antiplatelet therapy. The recurrence rate was 7 % for the homogeneous type, 21 % for the laminar type, 38 % for the separated type, and 0 % for the trabecular type. The rate of recurrence was significantly lower in the homogeneous and trabecular type than in the laminar and separated type. We performed a multivariate logistic regression analysis and found that postoperative midline shifting (OR, 3.6; 95 % CI, 1.618-7.885; p = 0.001), diabetes mellitus (OR, 2.2; 95 % CI, 1.196-3.856; p = 0.010), history of seizure (OR, 2.6; 95 % CI, 1.210-5.430; p = 0.014), width of hematoma (OR, 2.1; 95 % CI, 1.287-3.538; p = 0.003), and anticoagulant therapy (OR, 2.7; 95 % CI, 1.424-6.960; p = 0.005) were independent risk factors for the recurrence of chronic subdural hematoma. CONCLUSIONS We have shown that postoperative midline shifting (≥5 mm), diabetes mellitus, preoperative seizure, preoperative width of hematoma (≥20 mm), and anticoagulant therapy were independent predictors of the recurrence of chronic subdural hematoma. According to internal architecture of hematoma, the rate of recurrence was significantly lower in the homogeneous and the trabecular type than the laminar and separated type.

Abstract
BACKGROUND There are few identified risk factors for traumatic brain injuries such as subdural hematoma (SDH). The aim of the present study was to investigate whether low cognitive performance in young adulthood is associated with SDH later in life. A second aim was to investigate whether this risk factor was associated with education and physical fitness. METHODS AND FINDINGS Word recollection, logical, visuospatial, and technical performances were tested at a mean age of 18.5 years in a prospective nation-wide cohort of 440,742 men. An estimate of global intelligence was calculated from these four tests. Associations between cognitive performance, education, physical fitness, and SDH during follow-up were explored using Cox regression analyses. During a median follow-up of 35 years, 863 SDHs were diagnosed in the cohort. Low global intelligence was associated with an increased risk of SDH during follow-up (hazard ratio [HR]: 1.33, per standard deviation decrease, 95% CI = 1.25-1.43). Similar results were obtained for the other measures of cognitive performance (HR: 1.24-1.33, p<0.001 for all). In contrast, a high education (HR: 0.27, comparing more than 2 years of high school and 8 years of elementary school, 95% CI = 0.19-0.39), and a high level of physical fitness (HR: 0.76, per standard deviation increase, 95% CI = 0.70-0.83), was associated with a decreased risk of suffering from a SDH. CONCLUSIONS The present findings suggest that reduced cognitive function in young adulthood is strongly associated with an increased risk of SDH later in life. In contrast, a higher level of education and a higher physical fitness were associated with a decreased risk of SDH.

Abstract
BACKGROUND Seizures are important neurologic complications of chronic subdural hematoma (CSDH). A better understanding of risk factors of seizures following CSDH is needed to identify the patient who will require treatment. METHODS This one-year retrospective study enrolled 100 adult CSDH patients. Baseline prognostic variables were analyzed by Cox's proportional hazards model after a minimum of 18 months of follow-up. RESULTS Seizures occurred in 11 CSDH patients, including acute symptomatic seizures in 6.0% (6/100) and unprovoked seizures in 5.0% (5/100). None progressed to status epilepticus during hospitalization. After a minimum of 18 months of follow-up, the mean Glasgow Outcome Scores (GOSs) were 4.1 ± 1.4 and 4.7 ± 0.7 for patients with and without seizures, respectively. Cox's proportional hazards model showed that only the mean GCS on admission (P = 0.004, OR = 0.78, 95% CI = 0.67-0.93) was independently associated with seizures, and a decrease of one mean GCS increased the seizure rate by 21.6%. CONCLUSION Lower mean GCS on admission is independently predictive of seizures, most of which occur within the first three months after CSDH.

Abstract
BACKGROUND Chronic subdural haematoma causes serious morbidity and mortality. It recurs after surgical evacuation in 5-30% of patients. Drains might reduce recurrence but are not used routinely. Our aim was to investigate the effect of drains on recurrence rates and clinical outcomes. METHODS We did a randomised controlled trial at one UK centre between November, 2004, and November, 2007. 269 patients aged 18 years and older with a chronic subdural haematoma for burr-hole drainage were assessed for eligibility. 108 were randomly assigned by block randomisation to receive a drain inserted into the subdural space and 107 to no drain after evacuation. The primary endpoint was recurrence needing redrainage. The trial was stopped early because of a significant benefit in reduction of recurrence. Analyses were done on an intention-to-treat basis. This study is registered with the International Standard Randomised Controlled Trial Register (ISRCTN 97314294). FINDINGS Recurrence occurred in ten of 108 (9.3%) people with a drain, and 26 of 107 (24%) without (p=0.003; 95% CI 0.14-0.70). At 6 months mortality was nine of 105 (8.6%) and 19 of 105 (18.1%), respectively (p=0.042; 95% CI 0.1-0.99). Medical and surgical complications were much the same between the study groups. INTERPRETATION Use of a drain after burr-hole drainage of chronic subdural haematoma is safe and associated with reduced recurrence and mortality at 6 months.

Abstract
The incidence of seizures in patients undergoing burr-hole crainiostomy with closed-system drainage for chronic subdural hematoma (CSDH) is low. The post-operative use of anticonvulsants is, thus, controversial. In this study, we tried to correlate pre-operative computed tomographic (CT) appearance of the CSDH with the need for post-operative seizure prophylaxis. From April 1998 to November 2001, 128 cases of CSDH surgically treated at our hospital were studied. All patients underwent burr-hole craniostomy with closed system drainage. All CSDHs were classified as low-density, isodense, and mixed-density lesions according to CT findings. The incidence of early post-operative seizures (within 3 weeks of surgery) among all patients was 5.4% (7/128). In the subgroups by lesion density, the incidences were 6.2% (1/16) in the low-density group, 2.4% (2/83) in the isodense group, and 13.7% (4/29) in the mixed-density group (all p < 0.05). The mean age among the seven patients (five males and two females) who had seizures was 71 years. The locations of the CSDHs among the 128 patients were the left side of the brain in 53 (41.4%) patients, right side in 45 (35.2%), and bilateral in 30 (23.4%) patients. Among the seven patients who suffered from post-operative seizures, five (71.4%) had left side CSDHs, one (14.2%) had a right side CSDH, and one (14.2%) had bilateral CSDHs. We concluded that the post-operative seizure rate appeared high in the group with mixed-density type lesions on CT, and in those with left unilateral CSDH. We suggest the use of prophylactic anticonvulsants for patients with mixed-density lesions on pre-operative CT.

Abstract
OBJECTIVE Chronic subdural hematoma is a very common condition seen usually in the later stages of life. Treatment, although apparently simple, is associated with some morbidity and mortality with a potential for recurrence. This is especially important as the average life span of humanity increases all over the world. METHODS A retrospective analysis of 647 cases of chronic subdural hematomas treated in NIMHANS was done. The aim of this study was to determine the factors responsible for the morbidity, mortality, and recurrence in patients with chronic subdural hematomas. RESULTS The patients were mostly men in the sixth and seventh decade of life and presented with headache, cognitive decline, or focal deficits. CT scan was done in all cases. 94% of the patients underwent evacuation of the hematoma. There was a mortality rate of 5%, and there was a recurrence of 21%. Statistical analysis for factors both for mortality and morbidity were done. CONCLUSIONS It was seen that statistically significant factors determining mortality were age, GCS at presentation, and associated illnesses like cardiac and renal failure. The statistically significant factors for recurrence are the presence of a thick subdural membrane visualized during surgery and brain, remaining at a depth at the end of evacuation of hematoma. Use of a subdural drain significantly reduced recurrences. The chronicity of the hematoma was not a factor determining mortality or morbidity. Drains were seen to significantly reduce recurrence in younger patients with better GCS and when the subdural membrane is seen at surgery and the brain remains at a depth at the end of hematoma evacuation.

Abstract
Unconscious patients are frequently referred to radiology departments for computed tomography (CT) of the brain. The objectives of these examinations are to define the underlying cause of impaired consciousness and in some cases to determine the severity of associated brain injury. There is often little history available to guide the clinician or radiologist, particularly in patients referred from the casualty department. In this review, we present the typical CT appearances of adult patients presenting with loss of consciousness for CT examination. We focus on the most common abnormalities that are identified in everyday radiological practice, emphasize important diagnostic signs that may enable a confident diagnosis to be made and discuss when further imaging may be warranted.

Abstract
PURPOSE To test the hypothesis that chronic subdural hematoma (CSDH) enlarges by the causative factors, this study has performed. MATERIALS AND METHODS In 10 patients with CSDH, coagulation factors in venous blood taken at the time of surgery and hematomic contents aspirated from the CSDH were studied, using both laboratory assays and microscopy. RESULTS When compared to the range of normal plasma, the hematoma fluids demonstrated a marked reduction in factor II, V, VII, VIII, and X, moderate reduction of factors IX and XI, and slight reduction of factor XII. Activated protein C and antithrombin III levels were decreased. The FDP (Fibrinogen Degradation Product) levels in chronic subdural hematoma were extremely high. The endothelial cells of the macrocapillaries (also called ''sinusoid'') showed numerous gap junctions between adjacent endothelial cells and a thinness or absence of the basement membrane, suggesting that the macrocapillaries are very fragile and susceptible to bleeding. CONCLUSION Excessive coagulation in the hematoma, predominantly via the extrinsic clotting pathway, local hyperfibrinolysis, transmitted pulsations, and characteristics of the macrocapillaries play an important role in the leakage of blood and the enlargement of CSDH.

Abstract
OBJECTIVE Mixed-density convexity subdural hematoma and interhemispheric subdural hematoma suggest nonaccidental head injury. The purpose of this retrospective observational study is to investigate subdural hematoma on noncontrast computed tomography in infants with nonaccidental head injury and to compare these findings in infants with accidental head trauma for whom the date of injury was known. PATIENTS AND METHODS Two blinded, independent observers retrospectively reviewed computed tomography scans with subdural hematoma performed on the day of presentation on 9 infant victims of nonaccidental head injury (mean age: 6.8 months; range: 1-25 months) and on 38 infants (mean age: 4.8 months; range: newborn to 34 months) with accidental head trauma (birth-related: 19; short fall: 17; motor vehicle accident: 2). RESULTS Homogeneous hyperdense subdural hematoma was significantly more common in children with accidental head trauma (28 of 38 [74%]; nonaccidental head trauma: 3 of 9 [33%]), whereas mixed-density subdural hematoma was significantly more common in cases of nonaccidental head injury (6 of 9 [67%]; accidental head trauma: 7 of 38 [18%]). Twenty-two (79%) subdural hematomas were homogeneously hyperdense on noncontrast computed tomography performed within two days of accidental head trauma, one (4%) was homogeneous and isodense compared to brain tissue, one (4%) was homogeneous and hypodense, and four (14%) were mixed-density. There was no statistically significant difference in the proportion of interhemispheric subdural hematoma, epidural hematoma, calvarial fracture, brain contusion, or subarachnoid hemorrhage. CONCLUSIONS Homogeneous hyperdense subdural hematoma is more frequent in cases of accidental head trauma; mixed-density subdural hematoma is more frequent in cases of nonaccidental head injury but may be observed within 48 hours of accidental head trauma. Interhemispheric subdural hematoma is not specific for inflicted head injury.

Abstract
In the United States, roughly one of every 100 children is subjected to some form of neglect or abuse; inflicted injury is responsible for approximately 1,200 deaths per year. Child physical abuse may manifest as virtually any injury pattern known to medicine. Some of the injuries observed in battered children are relatively unique to this population (especially when observed in infants) and therefore are highly suggestive of nonaccidental, or inflicted, injury. Worrisome injuries include rib fracture, metaphyseal fracture, interhemispheric extraaxial hemorrhage, shear-type brain injury, vertebral compression fracture, and small bowel hematoma and laceration. As noted, however, virtually any injury may be inflicted; therefore, careful consideration of the nature of the injury, the developmental capabilities of the child, and the given history are crucial to determine the likelihood that an injury was inflicted. The majority of these injuries are readily detectable at imaging, and radiologic examination forms the mainstay of evaluation of child physical abuse. Detection of metaphyseal fracture (regarded as the most specific radiographically detectable injury in abuse) depends on high-quality, small field-of-view radiographs. The injury manifests radiographically as a lucent area within the subphyseal metaphysis, extending completely or partially across the metaphysis, roughly perpendicular to the long axis of the bone. Acute rib fractures (which in infants are strongly correlated with abuse) appear as linear lucent areas. They may be difficult to discern when acute; thus, follow-up radiography increases detection of these fractures. For skull injuries, radiography is best for detecting fractures, but computed tomography and magnetic resonance imaging best depict intracranial injury.

Abstract
Non-accidental head injury (NAHI) is a major cause of neurological disability and death during infancy. Radiological imaging plays a crucial role in evaluating craniospinal injury, both for guiding medical management and the forensic aspects of abusive trauma. The damage sustained is varied, complex and may be accompanied by an evolving pattern of brain injury secondary to a cascade of metabolic and physiological derangements. Regrettably, many cases are poorly or incompletely evaluated leading to diagnostic errors and difficulties in executing subsequent child care or criminal proceedings. It is evident, from cases referred to the authors, that imaging protocols for NAHI are lacking (or only loosely adhered to, if present) in many centres throughout the U.K. Future research in this field will also be hampered if there is a lack of consistent and reliable radiological data. There is no nationally agreed protocol for imaging NAHI. We propose such a protocol, based upon a wide experience in the medical management of child abuse and extensive involvement in the medicolegal aspects of NAHI.

Abstract
This article reviews the essential primary and secondary injuries attributable to traumatic brain injury (TBI) which causes one third of all injury deaths in the United States. Motor vehicle crashes, falls, assaults, guns, sports, and recreational activities are the major causes of TBI. Secondary peak incidences of TBI occur in infants and children and the elderly. Conditions that increase risk for accidents include alcoholism, prior head injury, prior meningitis, seizure disorders, mental retardation, and psychiatric disorders. However, gunshot wounds to the head are steadily increasing and since 1990 have caused more deaths each year than motor vehicle accidents. The incidence, severity, etiology, and specific types of injuries have been assessed in clinicopathologic studies of head injuries. The pathologic features of both the primary and secondary lesions attributed to TBI should be understood by anyone caring for head-injured patients. The computed tomography (CT) and magnetic resonance (MR) images mirror the pathologic abnormalities found in head trauma. Radiologists must accurately interpret the CT and MR images of injured patients. Forensic pathologists have long appreciated the characteristic focal lesions, such as coup and contracoup contusions, that occur in falls or vehicle accidents, but the understanding of diffuse injuries has been more elusive. Understanding the nature of the focal and diffuse injuries is critical to understanding the morbidity and mortality of brain injury.

Abstract
The clinical, radiological, and operative factors of recurrent chronic subdural hematoma (CSDH) were retrospectively analyzed in 116 patients with CSDH in 134 hemispheres, treated by one burr hole surgery. The correlation of recurrence was evaluated with personal and clinical factors such as age, sex, history of head injury, and interval from onset of initial symptoms to hospitalization; laboratory findings such as bleeding tendency and liver function; computed tomography (CT) findings such as hematoma density and brain atrophy; and operative findings such as additional procedures and postoperative residual air. The recurrence group (RG) included 10 hemispheres (7.5%) in 10 patients (8.6%). The interval from onset of symptoms to hospitalization was significantly shorter in the RG than in the nonrecurrence group (NRG). Headache was more frequently seen in the RG than in the NRG. Density of hematoma on CT was classified into five types: Low, iso, and high density, niveau, and mixed, and the incidence of recurrence was 0%, 2.3%, 17.2%, 12.5%, and 6.5%, respectively. Larger amounts of residual air in the postoperative hematoma cavity were associated with recurrence of CSDH. CSDH that progresses rapidly in the acute stage and appears as high density on preoperative CT is associated with a high incidence of recurrence. Intraoperative air invasion to the hematoma cavity should be avoided to prevent recurrence.

Abstract
OBJECT A wide variation in postoperative drainage volumes is observed during treatment of chronic subdural hematoma (CSDH) with twist-drill or burr-hole craniostomy and closed-system drainage. In this study the authors investigate the causes of the variation, the clinical significance thereof, and its influence on treatment outcome. METHODS A total of 175 cases were investigated between January 1991 and December 1997. Of these, 145 patients had surgery for CSDH, of whom 30 had bilateral lesions. The cases of CSDH were divided into five subtypes (low-density, isodense, high-density, mixed-density, and layering types) on the basis of the brain computerized tomography (CT) findings. Burr-hole craniostomies with closed-system drainage were performed in all patients and the drainage was maintained for 5 days, during which daily amounts of fluid were measured. The mean drainage volume over 5 days was 320 ml, with the largest volume (413 ml) seen in the low-density type and the smallest (151 ml) in the mixed-density type of CSDH. There were recurrences in six patients (seven instances, 4%). The mixed-density type had the highest recurrence rate (8.6%), whereas there was no recurrence for the low-density type. There were no recurrences in 81 patients in whom the total drainage volumes for 5 days were more than 200 ml, but there were recurrences in six (seven instances) of 94 patients in whom the total drainage volume was less than 200 ml. CONCLUSIONS The postoperative drainage volumes varied greatly because of differences in the outer membrane permeability of CSDH, and such variation seems to be related to the findings on the CT scans obtained preoperatively. Patients with CSDH in whom there is less postoperative drainage than expected should be carefully observed, with special attention paid to the possibility of recurrence.
