Efficacy and safety of steroids for chronic subdural hematoma: A systematic review and meta-analysis. Surg Neurol Int 2023; 14:449. [PMID: 38213424 PMCID: PMC10783700 DOI: 10.25259/sni_771_2023] [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: 09/18/2023] [Accepted: 11/28/2023] [Indexed: 01/13/2024] Open
Abstract
Background Chronic subdural hematoma (CSDH) is a condition characterized by the accumulation of fluid, blood, and blood breakdown products between the brain's arachnoid and dura mater coverings. While steroids have been explored as a potential treatment option, their efficacy and safety remain uncertain. This meta-analysis and systematic review aimed to assess the impact of steroids on CSDH management, including mortality, recurrence, complications, and functional outcomes. Methods We conducted a comprehensive literature search in major electronic databases up to June 2023, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and Cochrane Handbook for Systematic Reviews and Interventions. Inclusion criteria encompassed adult patients with CSDH, the use of steroids as monotherapy or adjuvant therapy, and clearly defined outcomes. Randomized controlled trials and cohort studies meeting these criteria were included in the study. Results The initial search yielded 4315 articles, with 12 studies meeting the inclusion criteria. Our findings indicate a non-significant trend toward reduced mortality with steroids in combination with standard care (Odds ratios [OR] = 0.66, 95% confidence interval [CI] 0.20-2.18). However, substantial heterogeneity was observed (I2 = 70%). Sensitivity analysis, excluding influential studies, suggested a potential increased mortality risk associated with steroids (OR = 1.47, 95% CI 0.87-2.48). Steroids showed a possible benefit in reducing the recurrence of CSDH (OR = 0.58, 95% CI 0.20-1.67), but with significant heterogeneity (I2 = 89%). No clear advantage of steroids was observed in terms of functional outcomes at three months (modified Rankin scale scores). Furthermore, steroids were associated with a significantly higher incidence of adverse effects and complications (OR = 2.17, 95% CI 1.48-3.17). Conclusion Steroids may have a potential role in reducing CSDH recurrence but do not appear to confer significant advantages in terms of mortality or functional outcomes. However, their use is associated with a higher risk of adverse effects and complications. Given the limitations of existing studies, further research is needed to refine the role of steroids in CSDH management, considering patient-specific factors and treatment protocols.

Abstract
PURPOSE To identify prognostic factors with emphasis on chronic subdural hematoma (CSDH) architecture that determines short-term outcome of middle meningeal artery embolization (MMAE). METHODS Consecutive CSDH patients treated by MMAE (November 2019 and March 2022) were retrospectively analyzed. Four architectures were analyzed: homogeneous, laminar, separated, and trabecular types. Predictor variables from baseline CT were correlated with radiological endpoint (≥ 50% of hematoma volume reduction), time to reach the endpoint, and rate of volume reduction. RESULTS Study included 50 patients with 56 CSDHs (median age [first quartile, Q1; third quartile, Q3] 70.5 [60, 78.3] years; 36 were men). Separated type reached the endpoint at a lower rate on both bivariate (p = 0.02) and multivariate Cox model (0.034). Kaplan-Meier curves demonstrated that the median [Q1, Q3] time for 50% of the hematomas to reach the endpoint was 5 [4, 8], 4 [3, 5], 15 [15, 15], and 11 [4, 19] weeks for homogeneous, laminar, separated, and trabecular types, respectively. Linear mixed-effect model demonstrated a significant variation in the slope of hematoma volume reduction that was - 4.16 (95% confidence interval [CI] - 5.4, - 2.9), - 6.7 (95% CI - 8.35, - 5.1), - 2.03 (95% CI - 4.14, 0.08), and - 5.06 (95% CI - 6.8, - 3.32) ml per week for homogeneous, laminar, separated, and trabecular subtypes, respectively. CONCLUSION Separated CSDH is a poor prognostic type in achieving radiological endpoint and a slower rate of volume reduction. While, homogeneous and laminar types reached the endpoint faster than separated and trabecular types on short-term follow-up.

Abstract
Background: Chronic subdural hematoma (CSDH) represents the most common neurosurgical disease. Given the demographic shift toward an aging population, the overall incidence of this condition is increasing. Nevertheless, clarity in the pathophysiological process is yet to be made. Several etiological mechanisms have been proposed to initiate and consequently promote fluid collection in the subdural space. Traumatic injury of the bridging veins has long been considered the primum movens of the pathology but increasing evidence shows that trauma is not the only factor involved. Along with recent advances we sought to understand the role of the cerebrospinal fluid (CSF) in the buildup of the intense inflammatory reaction that characterizes CSDH. Methods: In the present study, we examined histological features of reactive membranes secondary to extracranial CSF leakage with CSDH-related membranes. Similarity and differences between the specimens were examined by means of light microscopy. Results: Histological similarities were consistently found between CSDH membranes and reactive membranes secondary to CSF leakage in the extracranial space. Activated histiocytes were highlighted in all specimens along with an intense inflammatory reaction. Conclusion: CSDH is most likely the result of a complex interaction among different pathophysiological events resulting from both traumatic and inflammatory etiologies. In the present work, we highlight how CSF leakage could be an early factor that leads to a cascade of events that culminates in CSDH formation.

Abstract
Chronic subdural hematoma (CSDH) is characterized by an encapsulated collection of old blood. Although CSDH has become the most frequent pathologic entity in daily neurosurgical practice, there are some unresolved research questions. In particular, the causes and recurrent risk factors of CSDH remain as an object of debate. The split of the dural border layer forms a few tiers of dural border cells over the arachnoid layer. Tissue plasminogen activator plays an important role as a key factor of defective coagulation. Historically, CSDH has often been treated via burr hole craniostomy using a closed drainage system. Several different operative strategies and peri-operative strategies such as the addition of burr holes, addition of cavity irrigation, position of drain, or postural position, have been described previously. Although the direction of the drainage tube, residual air, low intensity of T1-weighted images on MRI, and niveau formation have been reported as risk factors for recurrence, antiplatelet or anticoagulant drug use has not yet been verified as a risk factor. Recently, pharmaceutical strategies, including atorvastatin, significantly improved the neurological function in CSDH patients. Many case series, without randomization, have been reported; and given its promising result, several randomized clinical trials using pharmaceutical as well as operative and perioperative strategies were initiated to obtain sufficient data. In contrast, relatively fewer basic studies have achieved clinical applications in CSDH, although it is one of the most common clinical entities. Further scientific basic research may be essential for achieving a novel treatment strategy for CSDH.

Use of the Subdural Hematoma in the Elderly (SHE) Score to Predict 30-Day Mortality After Chronic Subdural Hematoma Evacuation. World Neurosurg 2021; 157:e294-e300. [PMID: 34648990 DOI: 10.1016/j.wneu.2021.10.072] [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: 07/19/2021] [Revised: 10/01/2021] [Accepted: 10/04/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND The Subdural Hematoma in the Elderly (SHE) score has been recently developed to assess the 30-day mortality in acute and chronic subdural hematomas in patients >65 years and has shown good reliability. We aimed to validate the SHE score's accuracy to predict 30-day mortality on a homogeneous cohort of patients undergoing surgical chronic subdural hematoma evacuation at our Institution. We also investigated whether the SHE score could reliably predict the occurrence of 30-day chronic subdural hematoma recurrence needing surgery. METHODS We included patients from our prospectively collected database from January 2018 to January 2021. Patients with the availability of the following information were enrolled: age, Glasgow Coma Scale score on admission, hematoma volume, medical history, and outcome at 30 days. The SHE score was calculated for each patient, and the association between greater scores and 30-day mortality was investigated and its ability to predict 30-day and disease recurrence. Statistical significance was assessed for P < 0.05. RESULTS Three hundred twenty-one patients were included. Of them, 40 (12.5%) displayed mortality within 30-day: specifically, 0% of the group of patients with SHE score = 0, 4.3% of SHE score = 1, 14.5% of SHE score = 2, 39.3% of SHE score = 3, and 37.5% of SHE score = 4, with a statistically significant linear trend between greater SHE scores and 30-day mortality rates (P < 0.001, area under the curve 0.75 [0.67-0.82]). No significant association of the SHE score with the risk of recurrence needing surgery was detected (P = 0.4). CONCLUSIONS The SHE score proved helpful in predicting 30-day mortality in patients with chronic subdural hematomas, but no utility was observed to predict disease recurrence.

Abstract
PURPOSE OF REVIEW The surgical management of trauma-related intracranial hemorrhage is characterized by marked heterogeneity. Large prospective randomized trials have generally been prohibited by the ubiquity of concordant pathology, diversity of trauma systems, and paucity of clinical equipoise among providers. RECENT FINDINGS To date, the results of retrospective studies and surgeon preference have driven the indications, modality, extent, and timing of surgical intervention in the global neurosurgical community. With advances in our understanding of the pathophysiology of hemorrhagic TBI and the advent of novel surgical techniques, a reevaluation of surgical indication, timing, and approach is warranted. In this way, we can work to optimize surgical outcomes, achieving maximal functional recovery while minimizing surgical morbidity.

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
Chronic subdural hematoma (CSDH) is a complex disease with an overall incidence of 1.7-20.6 per 100,000 persons per year and is more commonly encountered in the elderly population. The pathophysiologic cycle of CSDH formation and expansion involves traumatic and inflammatory components that promote the formation of membranes with permeable neovessels. Many drugs targeting different elements of this cycle are being actively investigated as potential therapeutic agents in CSDH. Burr hole craniostomy appears to be the most commonly used procedure for surgical evacuation, and outcomes are generally favorable. Recurrence can occur in 10%-20% of patients and is associated with several clinical and radiographic predictors. Middle meningeal artery embolization represents one of the latest additions to the therapeutic arsenal of cerebrovascular specialists in treating CSDH and is being critically evaluated in numerous ongoing clinical trials.

Abstract
Chronic subdural hematomas (CSDHs) frequently affect the elderly population. The postoperative recurrence rate of CSDHs is high, ranging from 3% to 20%. Both qualitative and quantitative analyses have been explored to investigate the mechanisms underlying postoperative recurrence. We surveyed the pathophysiology of CSDHs and analyzed the relative factors influencing postoperative recurrence. Here, we summarize various qualitative methods documented in the literature and present our unique computer-assisted quantitative method, published previously, to assess postoperative recurrence. Imaging features of CSDHs, based on qualitative analysis related to postoperative high recurrence rate, such as abundant vascularity, neomembrane formation, and patent subdural space, could be clearly observed using the proposed quantitative analysis methods in terms of mean hematoma density, brain re-expansion rate, hematoma volume, average distance of subdural space, and brain shifting. Finally, artificial intelligence (AI) device types and applications in current health care are briefly outlined. We conclude that the potential applications of AI techniques can be integrated to the proposed quantitative analysis method to accomplish speedy execution and accurate prediction for postoperative outcomes in the management of CSDHs.

Abstract
AIM Chronic subdural hematoma (CSDH) is typically in elderly and rarely in young people. To prevent complications and re-bleeding after surgical treatment of CSDH it is important to assess the risk factors as coagulation disorders especially in young patients (below 65 years) with no history of head trauma, alcohol abuse or anticoagulant therapy. PATIENTS AND METHODS This study consists of 16 patients (12 males, 4 females) with age ranging from 27 to 59 years (median 48,25 years) operated for CSDH. All patients are submitted to routine coagulation parameters pre-operatively and complete screening for unknown coagulation deficit in the follow-up. RESULTS Factor VII was altered in 6 out of 16 patients and one patient had the alteration of the Von Willebrand factor. Recurrence occurred in 4 out of 16 patients and all of these patients were positive for factor VII deficiency. Three pts were in therapy with ASA. No patients were alcoholists or suffered from hematological disease. CONCLUSION In this study we documented that the decreased activity of VII factor may play a role in the pathophysiology and recurrence of spontaneous CSDH in young adults. We suggest that for young patients aged under 65 y.o. suffered from CSDH the screening of coagulation factors is useful to planning a safely and correct surgical therapy.

Abstract
INTRODUCTION Embolization of the middle meningeal artery (MMA) has emerged as a minimally invasive means of managing subdural hematoma. The purpose of this study was to systematically review the literature on the safety and effectiveness of this treatment and to share our clinical experience. METHODS This review was registered with PROSPERO. PubMed, CINAHL, EMBASE, and the Cochrane Library were searched using MeSH (Medical Subject Headings) terms for MMA embolization and chronic subdural hematoma (CSDH) from January 2000 to November 2018. All articles in the English language literature describing MMA embolization for CSDH were included, irrespective of study design. Consecutive patients who underwent MMA embolization at our hospital between January 2017 and June 2018 comprised our clinical experience. RESULTS Fifteen studies with 193 procedures were included in the review. Ninety-five cases (49.2%) involved primary MMA embolization; 88 embolizations (45.6%) for recurrent CSDH and 10 (5.2%) for prophylaxis after surgical evacuation were performed. Recurrence after MMA embolization requiring further treatment occurred in 7 cases (3.6%). All other patients had symptomatic relief with no further recurrence. No procedure-related complications were reported. Polyvinyl alcohol was the most commonly used material. Our series included 8 patients treated with Onyx. All had symptom relief and significant reduction in hematoma size; no recurrences or procedure-related complications were observed. CONCLUSIONS MMA embolization of CSDH is safe and effective for CSDH treatment based on a documented recurrence rate of 3.6% and lack of reported complications.

Abstract
BACKGROUND Anticoagulants(ACs) and antiplatelet aggregation agents(AAAs) seem to be correlated to a higher incidence of chronic subdural hematoma(CSDH) but whether or not they contribute to its recurrence is debated. Few data are available on clinical outcomes and indications for the management of this therapy are not so well defined. We investigated the role of ACs and AAAs in modifying patients clinical outcomes treated for CSDH, especially for re-bleedings. METHODS This retrospective study, enrolled patients treated for CSDH. Patients characteristics were recorded including drugs used (antiplatelet/anticoagulant) and clinical conditions (Modified Rankin Scale-mRS) upon admission. Patients underwent surgery(burrhole vs minicraniectomy) with subdural drainage positioning. Clinical/radiological follow-ups were performed at one and six months. Chi square/Fisher exact test were used to compare variables and stepwise backward logistic regression analysis was used for defining their impact on complications, risk of re-bleeding and reoperation. RESULTS 230 patients (45 on ACs, 76 on AAAs and 9 on both)were enrolled. Higher mRS scores were significantly associated with a higher risk of general complications (OR = 3.78, CI 95% 1.66- 8.62, p=0.002), higher risk of rebleeding (OR =15.82, CI 95% 4.33-57.90, p <0.001) and re- operation (OR=11.39, CI 95% 3.35-37.56, p<0.0001). No statistically significant association was found between AAAs or ACs and complications or re- bleedings or risk of reoperation. CONCLUSIONS AAAs and ACs alone do not seem to worsen the clinical outcome or increase re- bleedings. mRS may be a predicting factor, since patients with higher scores showed a worse outcome and an increased risk of re-bleeding, general complications and reoperation.

Abstract
BACKGROUND Antiplatelet therapy in patients with chronic subdural hematoma (cSDH) presents significant neurosurgical challenges. Given the lack of guidelines regarding perioperative management with antiplatelet therapy, it is difficult to balance the patient's increased cardiovascular risk and prevalence of cSDH. OBJECTIVE To better understand the risk and recurrence rates related to resuming low-dose acetylsalicylic acid (ASA) by evaluating our patients' resumption of low-dose ASA at various times after burr-hole drainage of the hematoma. METHODS In our retrospective study, 140 consecutive patients taking low-dose ASA undergoing surgical evacuation of cSDH were included. Data included baseline characteristics and rates of recurrence, morbidity, and mortality. A multivariate logistic regression model analyzed the association between ASA resumption time and recurrence rates. RESULTS No statistically significant association was observed between early postoperative resumption of low-dose ASA and recurrence of cSDH (odds ratio, 1.01; 95% confidence interval, 1.001-1.022; P = .06). Corresponding odds ratios and risk differences for restarting ASA treatment on postoperative days 1, 7, 14, 21, 28, 35, or 42 were estimated at 1.53 and 5.9%, 1.42 and 5.1%, 1.33 and 4.1%, 1.23 and 3.2%, 1.15 and 2.2%, 1.07 and 1.1%, and 1.01 and 0.2%, respectively (P > .05). Cardiovascular event rates, surgical morbidity, and mortality did not significantly differ between patients with or without ASA therapy. CONCLUSION Given the few published studies regarding ASA use in cranial neurosurgery, our findings elucidate one issue, showing comparable recurrence rates with early or late resumption of low-dose ASA after burr-hole evacuation of cSDH. ABBREVIATIONS ASA, acetylsalicylic acidCAD, coronary artery diseaseCI, confidence intervalcSDH, chronic subdural hematomaGCS, Glasgow Coma ScalemRS, modified Rankin ScaleOR, odds ratioRD, risk difference.

Abstract
Chronic subdural haematoma (CSDH) is an encapsulated collection of blood and fluid on the surface of the brain. Historically considered a result of head trauma, recent evidence suggests there are more complex processes involved. Trauma may be absent or very minor and does not explain the progressive, chronic course of the condition. This review focuses on several key processes involved in CSDH development: angiogenesis, fibrinolysis and inflammation. The characteristic membrane surrounding the CSDH has been identified as a source of fluid exudation and haemorrhage. Angiogenic stimuli lead to the creation of fragile blood vessels within membrane walls, whilst fibrinolytic processes prevent clot formation resulting in continued haemorrhage. An abundance of inflammatory cells and markers have been identified within the membranes and subdural fluid and are likely to contribute to propagating an inflammatory response which stimulates ongoing membrane growth and fluid accumulation. Currently, the mainstay of treatment for CSDH is surgical drainage, which has associated risks of recurrence requiring repeat surgery. Understanding of the underlying pathophysiological processes has been applied to developing potential drug treatments. Ongoing research is needed to identify if these therapies are successful in controlling the inflammatory and angiogenic disease processes leading to control and resolution of CSDH.

Abstract
BACKGROUND Twist drill craniostomy (TDC) is a minimally invasive and cost-effective technique to treat chronic subdural hematomas (CSDHs). Predictors for treatment success such as imaging characteristics, hematoma volume, and drainage volume are not established; thus, they are purpose of this analysis. MATERIAL AND METHODS We retrospectively evaluated all data of patients with CSDH undergoing TDC in our institution between January 2010 and December 2013. We analyzed imaging characteristics (extension and composition), volumetrically calculated pre- and postoperative hematoma volumes, measured drainage volume, and clinical course. Primary treatment success was defined as sufficient if definitive treatment was achieved via a single TDC (TDC-1) and insufficient if more than one TDC was needed. The need for open surgical evacuation was defined as treatment failure. RESULTS Data of 233 patients undergoing 387 TDCs were available for our study. A total of 67% of TDCs treated CSDHs effectively, whereas the remainder required further open surgical evacuation. Via use of the median-split-method, we found that sufficient treatment was achieved more frequently in smaller hematomas (P < 0.05). Treatment effectiveness was neither correlated with hematoma image characteristics (presence of membranes: P = 0.11, extent of chronification: P = 0.55) nor with the respective drainage volume (P = 0.95). Residual hematoma volume was consistently greater than expected by drainage calculation (P < 0.05). CONCLUSIONS TDC is an effective treatment option for CSDH. Sufficient treatment with single TDC was more common in smaller hematomas with an associated smaller residual hematoma. Failure of brain re-expansion after TDC may increase the treatment failure rates. In these cases, an open surgical evacuation might accelerate treatment and clinical recovery.

Abstract
BACKGROUND Chronic subdural haematomas (cSDHs) have shown an increasing incidence in an ageing population over the last 20 years, while unacceptable recurrence rates of up to 30 % persist. The recurrence rate of cSDH seems to be related to the excessive neoangiogenesis in the parietal membrane, which is mediated via vascular endothelial growth factor (VEGF). This is found to be elevated in the haematoma fluid and is dependent on eicosanoid/prostaglandin and thromboxane synthesis via cyclo-oxygenase-2 (COX-2). With this investigator-initiated trial (IIT) it was thought to diminish the recurrence rate of operated-on cSDHs by administering a selective COX-2 inhibitor (Celecoxib) over 4 weeks' time postoperatively in comparison to a control group. METHOD The thesis of risk reduction of cSDH recurrence in COX-2-inhibited patients was to be determined in a prospective, randomised, two-armed, open phase-II/III study with inclusion of 180 patients over a 2-year time period in four German university hospitals. The treated- and untreated-patient data were to be analysed by Fisher's exact test (significance level of alpha, 0.05 [two-sided]). RESULTS After screening of 246 patients from January 2009 to April 2010, the study had to be terminated prematurely as only 23 patients (9.3 %) could be enrolled because of on-going non-steroid anti-rheumatic (NSAR) drug treatment or contraindication to Celecoxib medication. In the study population, 13 patients were treated in the control group (six women, seven men; average age 66.8 years; one adverse event (AE)/serious adverse event (SAE) needing one re-operation because of progressive cSDH (7.7 %); ten patients were treated in the treatment group (one woman, nine men; average age 64.7 years; five AEs/SAEs needing two re-operations because of one progressive cSDH and one wound infection [20 %]). Significance levels are obsolete because of insufficient patient numbers. CONCLUSIONS The theoretical advantage of COX-2 inhibition in the recurrent cSDH could not be transferred into the treatment of German cSDH patients as 66.6 % of the patients showed strict contraindications for Celecoxib. Furthermore, 55 % of the patients were already treated with some kind of COX-2 inhibition and, nevertheless, developed cSDH. Thus, although conceptually appealing, an anti-angiogenic therapy with COX-2 inhibitors for cSDH could not be realised in this patient population due to the high prevalence of comorbidities excluding the administration of COX2 inhibitors.

Abstract
Different surgical procedures have been used in the management of chronic subdural hematoma (CSDH). Nowadays treatment with burr hole is more preferable than craniotomy in most clinics. We present two cases of CSDH, which caused neurological deficits. In both cases cortical membranectomy was performed following craniotomy. After this procedure, significant improvement was observed in patients neurological deficits. We recommend that craniotomy and subtotal membranectomy may be a more adequate choice in such cases. This report underlined that craniotomy is still an acceptable, safe, efficient and even a better procedure in selected patients with CSDH.

Abstract
Objective Magnetic resonance imaging (MRI) of chronic subdural hematoma (CSDH) detects various patterns, which can be attributed to many factors. The purpose of this study was to measure the level of interleukin-6 (IL-6), interleukin-8 (IL-8), and highly specific protein [beta-trace protein (βTP)] for cerebrospinal fluid (CSF) in CSDHs, and correlate the levels of these markers with the MRI findings. Methods Thirty one patients, treated surgically for CSDH, were divided on the basis of MRI findings into hyperintense and non-hyperintense groups. The concentrations of IL-6, IL-8, and βTP in the subdural fluid and serum were measured. The βTP was considered to indicate an admixture of CSF to the subdural fluid if βTP in the subdural fluid (βTPSF)/βTP in the serum (βTPSER)>2. Results The mean concentrations of IL-6 and IL-8 of the hyperintense group (n=17) of T1-WI MRI were 3975.1±1040.8 pg/mL and 6873.2±6365.4 pg/mL, whereas them of the non-hyperintense group (n=14) were 2173.5±1042.1 pg/mL and 2851.2±6267.5 pg/mL (p<0.001 and p=0.004). The mean concentrations of βTPSF and the ratio of βTPSF/βTPSER of the hyperintense group (n=13) of T2-WI MRI were 7.3±2.9 mg/L and 12.6±5.4, whereas them of the non-hyperintense group (n=18) were 4.3±2.3 mg/L and 7.5±3.9 (p=0.011 and p=0.011). Conclusion The hyperintense group on T1-WI MRI of CSDHs exhibited higher concentrations of IL-6 and IL-8 than non-hyperintense group. And, the hyperintese group on T2-WI MRI exhibited higher concentrations of βTPSF and the ratio of βTPSF/βTPSER than non-hyperintense group. These findings appear to be associated with rebleeding and CSF admixture in the CSDHs.

Abstract
Object
The etiology of chronic subdural hematoma (CSDH) in nongeriatric patients (≤ 60 years old) often remains unclear. The primary objective of this study was to identify spinal CSF leaks in young patients, after formulating the hypothesis that spinal CSF leaks are causally related to CSDH.
Methods
All consecutive patients 60 years of age or younger who underwent operations for CSDH between September 2009 and April 2011 at Bern University Hospital were included in this prospective cohort study. The patient workup included an extended search for a spinal CSF leak using a systematic algorithm: MRI of the spinal axis with or without intrathecal contrast application, myelography/fluoroscopy, and postmyelography CT. Spinal pathologies were classified according to direct proof of CSF outflow from the intrathecal to the extrathecal space, presence of extrathecal fluid accumulation, presence of spinal meningeal cysts, or no pathological findings. The primary outcome was proof of a CSF leak.
Results
Twenty-seven patients, with a mean age of 49.6 ± 9.2 years, underwent operations for CSDH. Hematomas were unilateral in 20 patients and bilateral in 7 patients. In 7 (25.9%) of 27 patients, spinal CSF leakage was proven, in 9 patients (33.3%) spinal meningeal cysts in the cervicothoracic region were found, and 3 patients (11.1%) had spinal cysts in the sacral region. The remaining 8 patients (29.6%) showed no pathological findings.
Conclusions
The direct proof of spinal CSF leakage in 25.9% of patients suggests that spinal CSF leaks may be a frequent cause of nongeriatric CSDH.

Abstract
OBJECTIVE Chronic subdural hematoma (CSDH) is one of the most common types of intra-cranial hemorrhages usually associated with trauma. Surgical treatment is the treatment of choice and burr hole trephination (BHT) is widely performed. The recurrence rate in the patients with CSDH is 3.7-30%. This study investigated the risk factors associated with the recurrence of patients with CSDH who underwent BHT. METHODS One hundred twenty-five patients with CSDH underwent BHT. Eight of 125 patients (6.4%) underwent reoperation for recurrent CSDH. We retrospectively analyzed demographic, clinical and radiological findings, catheter tip location and drainage duration as the risk factors for the recurrence of CSDH. RESULTS Recurrence of CSDH in the high- or mixed-density groups was significantly higher than those in the low- or iso-density groups (p<0.001). Placement of catheter tip at the temporoparietal area was associated with a significantly higher recurrence rate of CSDH than placement at the frontal area (p=0.006) and the brain re-expansion rate (BRR) was much lower than placement at the frontal area (p<0.001). CONCLUSION The operation may be delayed in high- and mixed-density groups, unless severe symptoms or signs are present. In addition, placing the catheter tip at the frontal area helps to reduce the incidence of postoperative recurrence of CSDH and to increase the BRR.

Abstract
Chronic subdural hematoma (CSDH) is a relatively common disorder in neurosurgery on elderly patients, though the mechanism that causes the disease remains unclear. Studies have suggested that local anticoagulation and inflammatory changes may be important in its pathogenesis. Most studies have used a basic bivariate statistical analysis to assess complex immunological responses in patients with this disorder, hence a more sophisticated multivariate statistical approach might be warranted. Our objective was to assess the association and correlation between the pro- and anti-inflammatory responses in a cohort of patients with chronic subdural hematoma (n=57) using an exploratory and confirmatory factor analysis. Thirteen assigned pro-inflammatory (TNF-α, IL-1β, IL-2, IL-2R, IL-6, IL-7, IL-12, IL-15, IL-17, CCL2, CXCL8, CXCL9 and CXCL10) and five assigned anti-inflammatory (IL-1RA, IL-4, IL-5, IL-10 and IL-13) cytokines from blood and hematoma fluid samples were examined. Exploratory factor analysis indicated two major underlying immunological processes expressed by the cytokines in both blood and hematoma fluid, but with a different pattern and particularly regarding the cytokines IL-13, IL-6, IL-4 and TNF-α. Scores from confirmatory factor analysis models exhibited a higher correlation between pro- and anti-inflammatory activities in blood (r=0.98) than in hematoma fluid samples (r=0.92). However, correlations of inflammatory processes between blood and hematoma fluid samples were lower and non-significant. A structural equation model showed a significant association between increased anti-inflammatory activity in hematoma fluid samples and a lower risk of recurrence, but this relationship was not statistically significant in venous blood samples. Moreover, these findings indicate that anti-inflammatory activities in the hematoma may play a role in the risk of a recurrence of CSDH.

Abstract
Inflammation and the coagulation system may influence the genesis of chronic subdural hematoma (CSDH). The appearance of CSDH on computed tomography (CT) varies with the stage of the hematoma. This study investigated the pathogenesis and the recurrence of CSDH by comparing cytokine levels with the CT features of CSDH in 26 patients with 34 CSDHs who underwent single burr-hole surgery at our hospital between October 2004 and November 2006. The hematoma components removed during the procedure were examined, and the hematoma serum levels of cytokines measured such as thrombomodulin (TM), interleukin-6 (IL-6), tumor necrosis factor-α (TNFα), and interleukin-10 (IL-10). Using CT, mixed density hematomas were distinguished from other homogeneous hematomas, and found that the TM level was significantly higher in mixed density hematomas than in homogeneous hematomas (p = 0.043). Mixed density hematomas were classified into three subtypes (laminar, separated, and trabecular hematomas). The TM level was significantly higher in laminar and separated hematomas than in other hematomas (p = 0.01). The levels of IL-6, TNFα, and IL-10 were extremely high, but showed no significant differences in relation to the CT features. Mixed density hematomas had high recurrence rate, as reported previously, and TM level was high in mixed density hematomas such as laminar and separated mixed density hematomas. The present findings suggest that the types of CSDH associated with high TM levels tend to have higher recurrence rate.

Abstract
Objective Density of the chronic subdural hematoma (cSDH) is variable. It often appears to be mixed density. Multiple densities of cSDH may result from multiple episodes of trauma. We investigated the frequency of mixed density and the causes of head injuries representing each density. Methods We could collect 242 cases of chronic SDH. The cSDHs were classified into four groups; hypodensity, homogeneous isodensity, layered type, and mixed type on the basis of CT scans. Results The density of cSDH was isodense in 115 patients, hypodense in 31 patients, mixed in 79 cases, and layered in 17 cases. The cSDH was on the left side in 115 patients, on the right side in 70 patients, and bilateral in 40 patients. The history of trauma was identifiable in 122 patients. The etiology could be identified in 67.7% of the hypodense hematomas, while it was obscure in 59.5% of the mixed hematomas. Conclusion Mixed density of cSDH results from multiple episodes of trauma, usually in the aged. It is hard to remember all the trivial traumas for the patients with the mixed density cSDHs. Although there were membranes within the mixed density hematomas, burr-holes were usually enough to drain the hematomas.

Abstract
Background and Purpose In the last decade there has been an increasing use of antiplatelet/anticoagulant agents in the elderly. The aim of the study was to evaluate the association between exposure to anticoagulant/antiplatelet therapy and chronic subdural haematoma-CSDH. Methods Single institution case-control study involving 138786 patients older than 60 years who visited our academic tertiary care Emergency Department from January 1st 2001 to December 31st 2010. 345 patients with CSDH (cases) were identified by review of ICD-9 codes 432.1 and 852.2x. Case and controls were matched with a 1∶3 ratio for gender, age (±5 years), year of admission and recent trauma. A conditional logistic model was built. A stratified analysis was performed with respect to the presence (842 patients) or absence (536 patients) of recent trauma. Results There were 345 cases and 1035 controls. Both anticoagulant and antiplatelet agents were associated with an increased risk of CSDH with an OR of 2.46 (CI 95% 1.66–3.64) and 1.42 (CI 95% 1.07–1.89), respectively. OR was 2.70 (CI 95% 1.75–4.15), 1.90 (CI 95% 1.13–3.20), and 1.37(CI 95% 0.99–1.90) for patients receiving oral anticoagulants, ADP-antagonists, or Cox-inhibitors, respectively. History of recent trauma was an effect modifier of the association between anticoagulants and CSDH, with an OR 1.71 (CI 95% 0.99–2.96) for patients with history of trauma and 4.30 (CI 95% 2.23–8.32) for patients without history of trauma. Conclusions Anticoagulant and antiplatelet therapy have a significant association with an increased risk of CSDH. This association, for patients under anticoagulant therapy, appears even stronger in those patients who develop a CSDH in the absence of a recent trauma.

Abstract
OBJECTIVE To investigate the reason for and the course of the double-layer appearance in the postoperative computed tomographies (CTs) of chronic subdural hematoma (CSDHs). METHODS We reviewed CSDH cases that were operated on during the last 3 years, between January 2008 and December 2010. We checked the preoperative, early postoperative, and late postoperative CTs of these patients. We investigated the relationship between the formation of a double-layer appearance and the prognoses and demographic characteristics of the patients. RESULTS Our database included 119 cases. A double-layer appearance was found in the postoperative CTs of 34 cases. The mean age of double-layer cases was older (72.5 ± 12.1) than that of the remaining 85 cases (63.1 ± 17.8). We did not find any relationship between the double-layer appearance and the reoperation/recurrence/death rates. CONCLUSIONS The double-layer appearance after evacuation of a CSDH might be caused by enlargement of the subarachnoid space and is not related to the presence of any residual hematoma. This appearance is not considered as a reason for reoperation.

Abstract
No class I evidence exists about the optimal treatment of chronic subdural hematoma (CSDH). The aim of this study was to evaluate current practice of CSDH patients with different neurological grades, and probable ambivalence towards various treatment paradigms, especially primary treatment with high-dose corticosteroids, among vascular neurologists and neurosurgeons. A questionnaire survey containing 4 questions, 1 consisting of cases, was sent to every vascular neurologist (n = 83) and neurosurgical centre (n = 15) in the Netherlands. The various treatment options were related to the treating physician, geographical distribution, both in general and for individual case. Sixty-two percent of surveys were returned. The proportion of patients primarily treated with corticosteroids was 17.5 % in 2009 and 20.5 % in 2010. Surgery by either burr holes or craniotomy was favoured by 61.1 % as primary treatment, and conservative treatment with corticosteroids by 22.4 %. Case studies revealed that surgery was preferred in case of severe neurological symptoms, whereas wait-and-see policy was preferred in case of mild symptoms without midline shift, of which 28 % would administer corticosteroids. Variety in answers was obtained in less pronounced cases. In the Netherlands, neurologists and neurosurgeons appear to favour surgery in CSDH patients as primary treatment, especially in severe cases. An ambivalent approach towards treatment protocols was shown, especially in patients with mild symptoms, regardless of hematoma size. A regimen of high-dose corticosteroids only, is preferred by about a quarter and predominantly in milder cases, and might depend on geographical distribution. These results suggest the need for a well-designed randomized trial.

Abstract
BACKGROUND Chronic subdural hematoma (CSDH) is commonly seen in neurosurgical practice, and the incidence is increasing. Treatment results are highly variable with respect to recurrences and complications. OBJECTIVE To report our single-center experience with the surgical treatment of CSDH in patients on preoperative corticosteroids and to assess possible predictors of outcome. METHODS The medical reports of 496 consecutive patients with CSDHs treated with burr hole craniostomy were analyzed retrospectively. Patient demographics, medication, hematoma, treatment characteristics, and laboratory values were scored in relation to outcome. Data were analyzed with the χ(2) test, independent t test, and multivariate backward regression. RESULTS Mean age was 71.5 ± 13.3 years (range, 18.6-95.4 years); the male-to-female ratio was 3:1. A decreased Glasgow Coma Scale (GCS) was observed in 63.1%, and GCS motor score on admission was < 6 in 25.2%. Recurrence and mortality rates were 11.9% and 5.3%, respectively. Multivariate analysis showed a longer period of preoperative dexamethasone administration (odds ratio [OR], 0.93 per day; P = .02), GCS motor score within 1 week after surgery of 6 (OR, 0.54; P = .02), postoperative complications (OR, 5.3; P < .001), and a left-sided hematoma (OR, 0.42; P = 0.010) to be significantly related to recurrence risk. CONCLUSION The present data suggest that in surgical treatment of CSDH with burr hole craniostomy, extended preoperative corticosteroid administration is associated with a lower recurrence rate. The use of corticosteroids does not seem to be related to a higher incidence of complications and treatment-related death compared with the current literature.

Abstract
BACKGROUND Chronic subdural haematoma (cSDH) is a common disease in neurosurgical practise, especially in elderly patients. This is of growing importance as the number of elderly people in the population is increasing steadily. There are scarce data focussing especially on elderly patients with cSDH. This study intended to evaluate the outcome and peri-operative risks in elderly patients with cSDH. METHODS We retrospectively reviewed medical records of 322 consecutive patients aged ≥65 years treated at our department between 2002 and 2009 focussing on outcome, aetiology, peri-operative risks, recurrence rate, and co-factors such as concomitant diseases and therapy with anticoagulants. The surgical procedure included burr-hole craniostomy followed by insertion of a subdural drain in each case. The outcome was classified according to the Karnofsky performance status (KPS) and modified Rankin Scale (mRS) score. Patients were divided into three groups according to age (group I: age 65-74 years, group II: 75-84 years, group III: 85-94 years). RESULTS Three hundred twenty-two patients underwent burr-hole craniostomy for cSDH in 399 surgical procedures. The mean age was 76 ± 7.9 years. After surgery, the mean neurological status improved in all three groups. Overall favourable outcome (mRS 0-2) was achieved in 83 % in group I, 68 % in group II and 51 % in group III, respectively. The rate of recurrence was lower in group III (7.5 %) compared to groups I (21.5 %) and II (27.37 %, p = 0.004). Overall, complication rates and peri-operative mortality (2.75 %) did not differ significantly between the age groups. CONCLUSION The data of the current study suggest that treatment of cSDH is safe in elderly patients. Patients aged above 85 years carry a greater risk for peri-operative complications, i.e. aSDH, and therefore have to be examined and monitored meticulously in order to prevent complications.

Abstract
INTRODUCTION Recurrence of chronic subdural haematoma (CSDH) occurs in up to 30% of patients. The rate of recurrence is higher in bilateral versus unilateral CSDH and the reason for this has not been fully elucidated. There are few quantitative studies of temporal changes in brain re-expansion after haematoma evacuation. The aim of this study is to use a simple volumetric image analysis method to quantify temporal changes of postoperative brain re-expansion in unilateral and bilateral CSDH. METHODS We reviewed computed tomography (CT) scans of 20 consecutive patients (16 men, 4 women; median age, 73.5 years) with CSDH (unilateral, n=10; bilateral, n=10) who underwent surgery (burr hole drainage on one or both sides) at our institutions during the period from June 2006 to August 2008. Haematoma volume was quantified preoperatively and on postoperative days 14 and 30 by computer-based image analysis (PACS Web 1000 System) of CT scans. We then calculated the brain re-expansion rate (BRR) for postoperative days 14 and 30. RESULTS Haematoma volume remained significantly higher (p<0.001) in bilateral versus unilateral CSDHs at both postoperative time points, and the BRR was significantly greater (p<0.001) in unilateral versus bilateral CSDH at both time points. CONCLUSION Results of this quantitative analysis provide definitive evidence for a poor BRR in bilateral compared to unilateral CSDH. This impairment may result in shifting of the brain and shearing of blood vessels, resulting in a higher recurrence rate.

Abstract
BACKGROUND We endeavored to analyze patients of subacute and chronic subdural hematomas studied in a 4-year period at the Sher-i-Kashmir Institute of Medical Sciences, Kashmir, India. METHODS The study was a retrospective analysis of 1181 patients of subdural hematomas. Demographic characteristics, clinico-radiologic features, operative modalities, and outcome were studied. Acute subdural hematomas were excluded from the study. RESULTS The mean age was 60.4 ± 12.4 and males outnumbered females. Chronic subdural collections were more common than subacute subdural hematomas and left side predominated. Two burr holes with closed-system drainage was used in most patients. Incidence of postoperative seizures is very low. Overall recurrence rates were low; however, multilocular hematomas had the highest incidence of recurrence. Morbidity and mortality were 7.53% and 2.96%, respectively. Preoperative neurologic grade correlated with outcome. CONCLUSIONS Subdural hematomas are common in elderly males. Preoperative neurologic grade dictates the outcome. Multilocular hematomas have a higher chance of recurrence. Craniotomy should be reserved for recurrent hematomas, and there may be a scope of craniotomy for multilocular chronic subdural hematomas at the outset. Antiepileptic prophylaxis is not routinely recommended.

Abstract
The main aim of this study was to investigate the influence of perioperative anticoagulation on the clinical course and outcome of 144 patients who underwent surgery for chronic subdural hematoma (CSDH). The outcome was categorized according to the modified Rankin Scale (mRS), Barthel Index and postoperative quality of life (QoL) scale. There was a significant correlation between preoperative aspirin medication and reoperation (Mann-Whitney U-test, p<0.05). Moreover, dosage and duration of postoperative low-molecular-weight heparin (LMWH) administration were associated with a higher risk of reoperation (Mann-Whitney U-test, p<0.01) and a worse outcome on the mRS (Mann-Whitney U-test, p<0.05). Intraoperative treatment with prothrombin complex concentrate led to a poor outcome on the mRS (Craddock-Flood test, p<0.05). Reoperation is the strongest predictive factor of a poor QoL after surgical treatment of CSDH. Both preoperative and postoperative anticoagulation treatment may affect reoperation rate and, thus, postoperative QoL.

Abstract
Seventy-one patients from northern Sweden were diagnosed with chronic subdural haematomas (CSDH) and treated at the Department of Neurosurgery at Umeå University Hospital over 12 months. Fifty-four patients with CSDH had a history of head trauma (trauma group), while 17 patients had no previous head trauma (non-trauma group). In the non-trauma group 71% of patients were treated with anticoagulants or antiplatelet aggregation agents (AAA) compared to 18% in the trauma group. Considering only AAA, 59% of the non-trauma patients were treated with these drugs versus 17% of patients in the trauma group. The recurrence rate for all patients was 17%. These findings confirm that the use of anticoagulants and AAA is over-represented in patients with non-traumatic CSDH. In our study, recurrence was not associated with previous use of anticoagulants or AAA.

Abstract
Abstract
OBJECTIVE
Most symptomatic chronic subdural hematomas are treated by subdural drainage. However, a subperiostal (i.e., extracranial) passive closed-drainage system in combination with double burr hole trepanation is used at our institution. Therefore, we wanted to analyze our results and compare them with the alternate treatment strategies reported in the current literature.
METHODS
In a retrospective single-center study, we analyzed the data of all patients undergoing double burr hole trepanation with a subperiostal passive closed-drainage system. Data analysis included general patient data, complications, postoperative seizure rate, and outcome.
RESULTS
One hundred forty-seven patients underwent surgery for 183 symptomatic chronic subdural hematomas. The perioperative mortality rate was 3.4%. Hematoma persistence or recurrence occurred in 13.1% of the cases. The postoperative seizure rate was 6.6%, and the infection rate was 1.6%, including 3 cases of superficial wound infection and 1 case with deep infection. The reintervention rate was 9.3%, including trepanation in 8.2% of the patients and craniotomy in 1.1%. The overall complication rate was 10.9%.
CONCLUSION
Double burr hole trepanation combined with a subperiostal passive closed-drainage system is a technically easy, highly effective, safe, and cost-efficient treatment strategy for symptomatic chronic subdural hematomas. The absence of a drain in direct contact with the hematoma capsule may moderate the risk of postoperative seizure and limit the secondary spread of infection to intracranial compartments.

Abstract
BACKGROUND AND PURPOSE Diffusion tensor imaging (DTI) was introduced as a good technique to evaluate structural abnormalities in the white matter. In this study, we used DTI to examine anisotropic changes of the pyramidal tracts displaced by chronic subdural hematoma (CSDH). MATERIALS AND METHODS Twenty-six patients with unilateral CSDH underwent DTI before and after surgery. We measured fractional anisotropy (FA) values in pyramidal tracts of bilateral cerebral peduncles and calculated the ratio of the FA value on the lesion side to that on the contralateral side (FA ratio) and compared the ratios with motor weakness. Moreover, the relationships between FA ratios and clinical factors such as age, sex, midline shift, interval from trauma, and hematoma attenuation on CT were evaluated. RESULTS FA values of pyramidal tracts on the lesion side were significantly lower than those on the contralateral side (0.66 +/- 0.07 versus 0.74 +/- 0.05, P < .0001). The FA ratio was correlated to the severity of motor weakness (r(2) = 0.32, P = .002). FA ratios after surgery improved significantly compared with those before surgery (0.96 +/- 0.08 versus 0.89 +/- 0.07, P = .0004). Intervals from trauma and the midline shift were significantly associated with decreased FA ratios (P = .0008 and P = .037). CONCLUSIONS In patients with CSDH, a reversible decrease of FA in the affected pyramidal tract on DTI was correlated to motor weakness. These anisotropic changes were considered to be caused by a reversible distortion of neuron fibers and vasogenic edema due to the hematoma.

Abstract
OBJECT The purpose of this study was to clarify whether cerebrospinal fluid (CSF) leakage into the subdural space is involved in the genesis of chronic subdural hematoma (CSDH) and subdural hygroma (SH) and to clarify whether this leakage of CSF into the subdural space influences the postoperative recurrence rate of CSDH and SH. METHODS In this prospective observational study, 75 cases involving patients treated surgically for CSDH (67 patients) or SH (8 patients) were evaluated with respect to clinical and radiological findings at presentation, the content of beta -trace protein (beta TP) in the subdural fluid (betaTPSF) and serum (betaTPSER), and the CSDH/SH recurrence rate. The betaTPSF was considered to indicate an admixture of CSF to the subdural fluid if betaTPSF/betaTPSER>2. RESULTS The median beta TPSF level for the whole patient group was 4.29 mg/L (range 0.33-51 mg/L). Cerebrospinal fluid leakage, as indicated by betaTPSF/betaTPSER>2, was found to be present in 93% of the patients with CSDH and in 100% of the patients with SH (p=0.724). In patients who later had to undergo repeated surgery for recurrence of CSDH/SH, the betaTPSF concentrations (median 6.69 mg/L, range 0.59-51 mg/L) were significantly higher (p=0.04) than in patients not requiring reoperation (median 4.12 mg/L, range 0.33-26.8 mg/L). CONCLUSIONS As indicated by the presence of betaTP in the subdural fluid, CSF leakage into the subdural space is present in the vast majority of patients with CSDH and SH. This leakage could be involved in the pathogenesis of CSDH and SH. Patients who experience recurrences of CSDH and SH have significantly higher concentrations of betaTPSF at initial presentation than patients not requiring reoperation for recurrence. These findings are presented in the literature for the first time and have to be confirmed and expanded upon by further studies.

Abstract
BACKGROUND Chronic subdural haematoma is one of the most common entities encountered in daily practice. Many methods of treatment have been reported, each with its own advantages and disadvantages. METHOD The authors present a novel technique for the management of chronic subdural haematoma which is a variation of a closed drainage system. After evacuation of the haematoma through a single burr hole, we inserted a Jackson Pratt drain into the subgaleal space, with suction facing the burr hole, allowing for continuous drainage of the remaining haematoma. FINDINGS We used the method for over 4 years to treat 224 patients. Seventeen patients (7.6%) needed a second operation for a recurrence of the haematoma no patient required a third operation. Postoperative complications developed in 3 patients. Two patients died while in the hospital, a mortality rate of 0.9%. CONCLUSIONS The use of suction assisted evacuation, is followed by results that compare satisfactorily to reports of previous methods, with a low rate of recurrence and complications. It is relatively less invasive and can be used in high risk patients.

Abstract
BACKGROUND Increasing numbers of patients presenting for intracranial surgery are receiving concurrent medication with low-dose aspirin, leading to dysfunctional circulating platelets, which might increase the peri-operative risk of bleeding. OBJECTIVE To survey the opinions and working practices of neurosurgical facilities in Germany regarding patients who present with low-dose aspirin medication before elective intracranial surgery. Methods. Questionnaires were sent to 210 neurosurgical facilities asking five main questions: (1) the adherence of any policy of stopping aspirin pre-operatively, (2) the personal risk assessment for patients with brain surgery under low-dose aspirin medication, (3) the preferred method of treatment for excessive bleeding in this context, (4) personal knowledge of haemorrhagic complications in this group of patients, and (5) the characteristics of the neurosurgical units concerned. RESULTS There were 138 (65.7%) valid responses. Of the respondents, 111 (80.4%) had a departmental policy for the discontinuation of pre-operative aspirin treatment. The mean time for discontinuation of aspirin pre-operatively was 7.3 days (range: 0-21 days). 107 respondents (77.5%) considered that patients taking low-dose aspirin were at increased risk for excessive peri-operative haemorrhage, and 80 (58%) reported having personal experience of such problems. Ninety-seven respondents (70.3%) would use special medical therapy, preferably desmopressin, if haemorrhagic complications developed intra-operatively. The mean amount of intracranial operations per year in each neurosurgical facility was 494 (range: 50-1700). CONCLUSIONS The majority of neurosurgical facilities in Germany have distinct departmental policies concerning the discontinuation of low-dose aspirin pre-operatively, with an average of 7.3 days. Three-quarter of the respondents felt that aspirin was a risk factor for haemorrhagic complications associated with intracranial procedures, and more than half of the interviewees reported having personal experience of such problems. Various medicamentous methods of counteracting aspirin-induced platelet dysfunction and excessive bleeding in this context are discussed and evaluated.

Abstract
✓ Chronic subdural hematomas (SDHs) generally occur in elderly patients. Its pathogenesis is usually related to head trauma with tearing and rupture of the bridging veins, although in some cases a history of trauma is not recognizable. There are many reports regarding the association between spontaneous chronic SDHs and an alteration in coagulative parameters. A coagulative disorder should be suspected when an unexplained hemorrhage occurs, especially in a young patient. The authors report on three young men with a deficiency in coagulation factor XIII (FXIII) who underwent surgery for chronic SDHs. The role of FXIII in the pathogenesis of chronic SDH is emphasized. In patients with unexplained chronic SDH all coagulation parameters and factors should be screened to identify an eventual coagulative disorder.

Abstract
Object. The goal of this paper was to investigate a possible relationship between the consumption of low-dose aspirin (LDA) and traumatic intracranial hemorrhage in an attempt to determine whether older patients receiving prophylactic LDA require special treatment following an incidence of mild-to-moderate head trauma.
Methods. Two hundred thirty-one patients older than 60 years of age, who arrived at the emergency department with a mild or moderate head injury (Glasgow Coma Scale [GCS] Scores 13–15 and 9–12, respectively), were included in the study. One hundred ten patients were receiving prophylactic LDA (100 mg/day) and these formed the aspirin-treated group. One hundred twenty-one patients were receiving no aspirin, and these formed the control group. There was no statistically significant difference between the two groups with respect to age, sex, mechanism of trauma, or GCS score on arrival at the emergency department. Most of the patients sustained the head injury from falls (88.2% of patients in the aspirin-treated group and 85.1% of patients in the control group), and had external signs of head trauma such as bruising or scalp laceration (80.9% of patients in the aspirin-treated group and 86.8% of patients in the control group). All patients underwent similar neurological examinations and computerized tomography (CT) scanning of the head.
The CT scans revealed evidence of traumatic intracranial hemorrhage in 27 (24.5%) patients in the aspirin-treated group and in 31 patients (25.6%) in the control group. Surgical intervention was required for five patients in each group (4.5% of patients in the aspirin-treated group and 4.1% of patients in the control group). A surprising number of the patients who arrived with GCS Score 15 were found to have traumatic intracranial hemorrhage, as revealed by CT scanning (11.5% of patients in the aspirin-treated group and 16.5% of patients in the control group). Surgery, however, was not necessary for any of these patients.
Conclusions. There was no statistically significant difference in the frequency or types of traumatic intracranial hemorrhage between patients who had received aspirin prophylaxis and those who had not. The authors conclude that LDA does not increase surgically relevant parenchymal or meningeal bleeding following moderate and minor head injury in patients older than 60 years of age.

Abstract
OBJECTIVE To evaluate the results of surgical treatment options for chronic subdural haematoma in contemporary neurosurgery according to evidence based criteria. METHODS A review based on a Medline search from 1981 to October 2001 using the phrases "subdural haematoma" and "subdural haematoma AND chronic". Articles selected for evaluation had at least 10 patients and less than 10% of patients were lost to follow up. The articles were classified by three classes of evidence according to criteria of the American Academy of Neurology. Strength of recommendation for different treatment options was derived from the resulting degrees of certainty. RESULTS 48 publications were reviewed. There was no article that provided class I evidence. Six articles met criteria for class II evidence and the remainder provided class III evidence. Evaluation of the results showed that twist drill and burr hole craniostomy are safer than craniotomy; burr hole craniostomy and craniotomy are the most effective procedures; and burr hole craniostomy has the best cure to complication ratio (type C recommendation). Irrigation lowers the risk of recurrence in twist drill craniostomy and does not increase the risk of infection (type C recommendation). Drainage reduces the risk of recurrence in burr hole craniostomy, and a frontal position of the drain reduces the risk of recurrence (type B recommendation). Drainage reduces the risk of recurrence in twist drill craniostomy, and the use of a drain does not increase the risk of infection (type C recommendation). Burr hole craniostomy appears to be more effective in treating recurrent haematomas than twist drill craniostomy, and craniotomy should be considered the treatment of last choice for recurrences (type C recommendation). CONCLUSIONS The three principal techniques-twist drill craniostomy, burr hole craniostomy, and craniotomy-used in contemporary neurosurgery for chronic subdural haematoma have different profiles for morbidity, mortality, recurrence rate, and cure rate. Twist drill and burr hole craniostomy can be considered first tier treatment, while craniotomy may be used as second tier treatment. A cumulative summary of data shows that, overall, the postoperative outcome of chronic subdural haematoma has not improved substantially over the past 20 years.

Abstract
OBJECTIVE The coincidence of coagulatopathy and chronic subdural haematoma (CSH) requires correction of coagulation to facilitate surgery. We investigated the correlation between coagulopathy and outcome in CSH patients. MATERIAL AND METHODS We analysed past medical history, surgical treatment and coagulation parameters of 114 patients. RESULTS Coagulation disorders were found in 42%. Preoperative treatment with prothrombin complex concentrate was necessary in 14%. A significant difference (P < 0.05) of the preoperative level of platelets was found between recurrent CSH and non-recurrent group. Totally, we had to perform re-operations in 17.5%. Eighty-one patients presented with Glasgow coma scale (GCS) > or = 13. After surgery GCS was > or = 13 in n = 92. There was an improvement of GCS in 46 cases, 61 patients maintained GCS score levels. Outcome was significantly worse in the alcoholic group (P < 0.001), and in the recurrent group (P < 0.05). In patients with substitution of coagulation factors, outcome was worse in the group with post-operative substitution only (P < 0.05). CONCLUSION In CSH, the coagulation parameters and a subtle correction of coagulation are of special interest, regarding the worse outcome in patients with recurrent CSH and in those requiring post-operative substitution.
