Abstract
INTRODUCTION Conservative therapy is a viable option for patients with chronic subdural hematoma (cSDH) who express no, or only mild symptoms. It is not clear which factors are associated with success of conservative therapy. This study aims to determine conservative therapy's success rate and to identify features possibly associated with success. METHODS A monocenter retrospective cohort study, including cSDH patients treated conservatively (wait-and-watch) from 2012 to 2022, was performed. The primary outcome was success of conservative therapy, defined as 'no crossover to surgery' during the follow-up period. Secondary outcomes were (1) factors associated with success, analyzed with univariate and multivariable logistic regression analyses, (2) 30-day mortality (3) time to crossover and (4) reasons for crossover. RESULTS We included 159 patients. Conservative therapy was successful in 96 (60%) patients. Hematoma volume (OR 0.79, 95% CI 0.69-0.92) and hypodense hematoma type (OR 3.57, 95% 1.38-9.23) were associated with success. Thirty-day mortality rate was 5% and the median duration between diagnosis and surgery was 19 days (IQR 8-39). Clinical deterioration was the most frequent reason for crossover (in 61/63 patients, 97%) and was accompanied by radiological hematoma progression in 42 patients (67%). CONCLUSION In this selected group of patients, conservative therapy was successful in 60%. Smaller hematoma volume and hypodense hematoma type were associated with success. As time until crossover was approximately three weeks, deploying conservative therapy as primary treatment seems safe and could be rewarding as surgical complications can be avoided. Improvement in patient selection in future cohorts remains warranted.

Abstract
Subdural hematoma (SDH) evacuation represents one of the most frequently performed neurosurgical procedures. Several reports cite a rise in both the age and number of patient's requiring treatment, due in part to an aging population and expanded anticoagulation use. However, limited data and conflicting conclusions exist on extreme-aged geriatric patients (≥ 85 years of age) after undergoing surgery. Patients undergoing SDH evacuation at a tertiary academic medical center between November 2013-December 2021 were retrospectively identified. The study group consisted of patients ≥ 85 years (Group 1) diagnosed with a chronic SDH surgically evacuated. A control group was created matching patients by 70-84 years of age, gender, and anticoagulation use (Group 2). Multiple metrics were evaluated between the two including length-of hospital-stay, tracheostomy/PEG placement, reoperation rate, complications, discharge location, neurological outcome at the time of discharge, and survival. A total of 130 patients were included; 65 in Group 1 and 65 in Group 2. Patient demographics, medical comorbidities, SDH characteristics, international normalized ratio, partial thromboplastin time, and use of blood thinning agents were similar between the two groups. Kaplan Meier survival analysis at one-year was 80% for Group 1 and 76% for Group 2. No significant difference was identified using the log-rank test for equality of survivor functions (p = 0.26). All measured outcomes including GCS at time of discharge, length of stay, rate of reoperations, and neurological outcome were statistically similar between the two groups. Backwards stepwise conditional logistic regression revealed no significant association between poor outcomes at the time of discharge and age. Alternatively, anticoagulation use was found to be associated with poor outcomes (OR 3.55, 95% CI 1.08-11.60; p = 0.036). Several outcome metrics and statistical analyses were used to compare patients ≥ 85 years of age to younger geriatric patients (70-84 years) in a matched cohort study. Adjusting for age group, gender, and anticoagulation use, no significant difference was found between the two groups including neurological outcome at discharge, reoperation rate, and survival.

Abstract
INTRODUCTION There is sufficient scientific literature that demonstrates favorable outcomes using the minimally invasive technique of middle meningeal artery embolization (MMAE) for the treatment of chronic subdural hematomas (cSDH). The authors evaluate the outcomes of 35 consecutive patients treated with MMAE, both with and without adjuvant surgical drainage (ASD), in an attempt to identify variables that may affect the outcome of patients treated with MMAE for cSDH. METHODS A multivariate retrospective analysis was performed on patients who received MMAE for cSDH, including age, size of cSDH, ASD, presence of unilateral or bilateral collections, and use of anticoagulants. RESULTS Twenty patients underwent MMAE with planned ASD, while 15 patients had MMAE only; these groups had an average cSDH size reduction (measured at its greatest width) of 74% and 69% of cSDH, respectively. Of the 15 patients who were initially treated only with MMAE, three (20%) required a rescue craniotomy. Twenty patients (57%) who had initially presented while receiving oral anticoagulants had an average of 71% size reduction with ASD compared to 74% reduction in those without ASD. Patients not using anticoagulants had an 84% and 78% average reduction in size, respectively. Twelve patients presented with bilateral cSDH; patients who received ASD had an average size reduction of 58%; those without ASD had 63%. Patients with unilateral cSDH had 85% and 83% reduction in size, respectively. CONCLUSION Middle meningeal artery embolization, with or without ASD, can be a useful alternative or adjunct to standard surgical treatment for cSDH. Our study found that only three of 35 patients (9%) treated with this method required any further surgical intervention. No patient who received ASD had a recurrence of their cSDH. Further investigation, including prospective randomized studies, would be useful to better identify which patients can benefit and variables that impact the outcome of patients undergoing MMAE.

Abstract
PURPOSE Placement of a subdural drain after burr-hole drainage of chronic subdural hematoma (cSDH) significantly reduces risk of its recurrence and lowers mortality at 6 months. Nonetheless, measures to reduce morbidity related to drain placement are rarely addressed in the literature. Toward reducing drain-related morbidity, we compare outcomes achieved by conventional insertion and our proposed modification. METHODS In this retrospective series from two institutions, 362 patients underwent burr-hole drainage of unilateral cSDH with subsequent subdural drain insertion by conventional technique or modified Nelaton catheter (NC) technique. Primary endpoints were iatrogenic brain contusion or new neurological deficit. Secondary endpoints were drain misplacement, indication for computed tomography (CT) scan, re-operation for hematoma recurrence, and favorable Glasgow Outcome Scale (GOS) score (≥ 4) at final follow-up. RESULTS The 362 patients (63.8% male) in our final analysis included drains inserted in 56 patients by NC and 306 patients by conventional technique. Brain contusions or new neurological deficits occurred significantly less often in the NC (1.8%) than conventional group (10.5%) (P = .041). Compared with the conventional group, the NC group had no drain misplacement (3.6% versus 0%; P = .23) and significantly fewer non-routine CT imaging related to symptoms (36.5% versus 5.4%; P < .001). Re-operation rates and favorable GOS scores were comparable between groups. CONCLUSION We propose the NC technique as an easy-to-use measure for accurate drain positioning within the subdural space that may yield meaningful benefits for patients undergoing treatment for cSDH and vulnerable to complication risks.

Abstract
Background The International Statistical Classification of Diseases (ICD) classifies subdural hematoma (SDH) as traumatic or non-traumatic. In clinical settings, however, SDH is typically described as either acute or chronic. Objective The goal of this study was to assess how the ICD Coding Tools captures the clinical terminology and propose an improved classification that would increase the system's usefulness in administrative, statistical and research applications. Methods We performed a retrospective analysis of patients who presented to our center with an ICD diagnostic code for either traumatic or non-traumatic SDH. A qualitative analysis of patients' charts was performed to identify elements relevant to management and prognosis, following which a meeting between expert investigators was held to elaborate a new classification of SDH. Imaging from all patients was then reviewed and cases were reclassified according to our proposed system. Results A total of 277 SDH cases were included. Themes documented in the charts included chronicity, etiology, side, and symptoms. We created a new classification which distinguishes acute SDH (aSDH) from membrane-associated SDH (mSDH). aSDH were further divided into traumatic aSDH (taSDH) and non-traumatic aSDH (ntaSDH), while mSDH were divided into acute on chronic (a/cSDH), subacute (sSDH) and chronic (cSDH) categories. Conclusion The ICD coding system correctly identifies taSDH and ntaSDH. However, it remains non-specific for mSDH. We propose this new SDH classification system to better capture chronicity and etiology - factors felt to impact management and prognosis.

Abstract
Background Chronic subdural hematoma (cSDH) is a disease affecting mainly elderly individuals. The reported incidence ranges from 2.0/100,000 to 58 per 100,000 person-years when only considering patients who are over 70 years old, with an overall incidence of 8.2-14.0 per 100,000 persons. Due to an estimated doubling of the population above 65 years old between 2000 and 2030, cSDH will become an even more significant concern. To gain an overview of cSDH hospital admission rates, treatment, and outcome, we performed this multicenter national cohort study of patients requiring surgical treatment of cSDH. Methods A multicenter cohort study included patients treated in 2013 in a Swiss center accredited for residency. Demographics, medical history, symptoms, and medication were recorded. Imaging at admission was evaluated, and therapy was divided into burr hole craniostomy (BHC), twist drill craniostomy (TDC), and craniotomy. Patients' outcomes were dichotomized into good (mRS, 0-3) and poor (mRS, 4-6) outcomes. A two-sided t-test for unpaired variables was performed, while a chi-square test was performed for categorical variables, and a p-value of <0.05 was considered to be statistically significant. Results A total of 663 patients were included. The median age was 76 years, and the overall incidence rate was 8.2/100,000. With age, the incidence rate increased to 64.2/100,000 in patients aged 80-89 years. The most prevalent symptoms were gait disturbance in 362 (58.6%) of patients, headache in 286 (46.4%), and focal neurological deficits in 252 (40.7%). CSDH distribution was unilateral in 478 (72.1%) patients, while 185 presented a bilateral hematoma with no difference in the outcome. BHC was the most performed procedure for 758 (97.3%) evacuations. CSDH recurrence was noted in 104 patients (20.1%). A good outcome was seen in almost 81% of patients. Factors associated with poor outcomes were age, GCS and mRS on admission, and the occurrence of multiple deficits present at the diagnosis of the cSDH. Conclusion As the first multicenter national cohort-based study analyzing the disease burden of cSDH, our study reveals that the hospital admission rate of cSDH was 8.2/100,000, while with age, it rose to 64.2/100,000. A good outcome was seen in 81% of patients, who maintained the same quality of life as before the surgery. However, the mortality rate was 4%.

Abstract
Background Chronic subdural hematoma (CSDH) is a neurosurgical condition with high prevalence. Many surgical approaches are recommended for treating CSDH, but there needs to be a consensus on the optimal technique. This network meta-analysis (NMA) compared the efficacy and safety of different surgical treatments for CSDH. Methods Electronic databases, including PubMed, Embase, and the Cochrane Library, were searched for relevant studies up to February 2023. An NMA was performed to compare the outcomes of patients with CSDH treated by single-hole or double-hole craniotomy (SBHC and DBHC, respectively), twist-drill craniotomy (TDC), mini-craniotomy, and craniotomy. The NMA protocol was registered at INPLASY (registration no. 202320114). Results The NMA included 38 studies with 7,337 patients. For efficacy outcomes, DBHC showed the highest surface under the cumulative ranking area (SUCRA) values for recurrence (96.3%) and reoperation (87.4%) rates. DBHC differed significantly from mini-craniotomy in recurrence rate (odds ratio [OR] = 0.58, 95% confidence interval [CI]: 0.35, 0.97) and from SBHC (OR = 0.48, 95% CI: 0.25, 0.91) and TDC (OR = 0.40, 95% CI: 0.20, 0.82) in reoperation rate. For operative time, TDC was superior to SBHC (mean difference [MD] = -2.32, 95% CI: -3.78 to -0.86), DBHC (MD = -3.61, 95% CI: -5.55, -1.67), and mini-craniotomy (MD = -3.39, 95% CI: -5.70, -1.08). Patients treated by TDC had a shorter hospital stay than those treated by SBHC (MD = -0.82, 95% CI: -1.51, -0.12). For safety outcomes, there were no significant differences between groups in mortality and complication rates; however, mini-craniotomy (79.8%) and TDC (78.1%) had the highest SUCRAs. Conclusion DBHC may be the most effective surgical treatment for CSDH based on the low recurrence and reoperation rates, although all examined techniques were relatively safe.

Abstract
BACKGROUND Neuroendoscopy is a very useful technique to Chronic Subdural Hematoma (CSH). But how to achieve the goal of treatment more minimally invasive?
AIM To develop a simple, fast and accurate preoperative planning method in our way for endoscopic surgery of patients with CSH.
METHODS From June 2018 to May 2020, forty-two patients with CSH, admitted to our hospital, were performed endoscopic minimally invasive surgery; computed tomography (CT) imaging was employed to locate the intracerebral hematoma and select the appropriate endoscopic approach before the endoscopic surgery. The clinical data and treatment efficacy were analyzed.
RESULTS According to the learning of CT scanning images, the surgeon can accurately design the best minimally invasive neuroendoscopic surgical approach and realize the precise positioning and design of the drilling site of the skull and the size of the bone window, so as to provide the most effective operation space with the smallest bone window. In this group, the average operation time was only about 1 h, and the clearance rate of hematoma was about 95%.
CONCLUSION Patients with CSH can achieve good therapeutic effect by using our way to positioning and design to assist the operation of CSH according to CT scan and image, and our way is very useful and necessary.

Abstract
BACKGROUND Recovery after traumatic brain injury (TBI) in older adults is usually affected by the presence of comorbidities, leading to more severe sequelae in this age group than in younger patients. However, there are only few reports that prospectively perform in-depth assessment of outcome following TBI in elderly. OBJECTIVE This study aims at documenting structural brain characteristics and functional outcome and quality of life in elderly patients 6 months after TBI and comparing these data with healthy volunteers undergoing the same assessments. METHODS Thirteen TBI patients ≥ 65 years old, admitted to the University Hospitals Leuven (Belgium), between 2019 and 2022 due to TBI, including all injury severities, and a group of 13 healthy volunteers with similar demographic characteristics were prospectively included in the study. At admission, demographic, injury, and CT scan data were collected in our database. Six months after the accident, a brain MRI scan and standardized assessments of frailty, sleep quality, cognitive function, motor function, and quality of life were conducted. RESULTS A total of 13 patients and 13 volunteers were included in the study, with a median age of 74 and 73 years, respectively. Nine out of the 13 patients presented with a mild TBI. The patient group had a significantly higher level of frailty than the control group, presenting a mean Reported Edmonton Frailty Scale score of 5.8 (SD 2.7) vs 0.7 (SD 1.1) (p < 0.01). No statistically significant differences were found between patient and control brain volumes, fluid attenuated inversion recovery white matter hyperintensity volumes, number of lesions and blackholes, and fractional anisotropy values. Patients demonstrated a significantly higher median reaction time in the One Touch Stockings of Cambridge (22.3 s vs 17.6, p = 0.03) and Reaction Time (0.5 s vs 0.4 s, p < 0.01) subtests in the Cambridge Neuropsychological Test Automated Battery. Furthermore, patients had a lower mean score on the first Box and Blocks test with the right hand (46.6 vs 61.7, p < 0.01) and a significantly higher mean score in the Timed-Up & Go test (13.1 s vs 6.2 s, p = 0.02) and Timed Up & Go with cognitive dual task (16.0 s vs 10.2 s, p < 0.01). Substantially lower QOLIBRI total score (60.4 vs 85.4, p < 0.01) and QOLIBRI-OS total score (53.8 vs 88.5, p < 0.01) were also observed in the patients' group. CONCLUSION In this prospective study, TBI patients ≥ 65 years old when compared with elder controls showed slightly worse cognitive performance and poorer motor function, higher fall risk, but a substantially reduced QoL at 6 months FU, as well as significantly higher frailty, even when the TBI is classified as mild. No statistically significant differences were found in structural brain characteristics on MRI. Future studies with larger sample sizes are needed to refine the impact of TBI versus frailty on function and QoL in elderly.

Abstract
The levels of angiogenic factors were analyzed in eight patients who underwent the embolization of chronic subdural hematoma (CSDH) with non-adhesive liquid embolic agents. Four of these patients had previously undergone surgical treatment for hematoma removal and had recurrences of a similar volume, and four had an increase in hematoma volume due to rebleeding. The levels of vascular endothelial growth factor (VEGF), matrix metallopeptidase 9 (MMP 9), angiopoietin-2 (Ang2), transforming growth factor beta 1 (TGF-β1) and platelet-derived growth factor BB (PDGF-BB) in the arterial and venous blood were analyzed. The most significant results were obtained from the peripheral venous blood samples. The levels of VEGF in the samples of all the patients were close to normal or slightly decreased. There was an increase in the MMP9 levels (the factor that contributes to the disintegration of the vessel wall components) in all the patients. The Ang2 and especially the PDGF TGF-β1 (the factor that plays an important role in the growth of the vessel wall from the already existing blood vessel tissue) levels were distinctly low in most of the cases and slightly elevated only in a number of patients who had previously been operated on. The results obtained show that there is an imbalance in the angiogenesis factors in patients with rebleeding CSDH. At the same time, the factors determining the formation of the vessel wall were reduced, and the levels of factors contributing to the degradation of extracellular matrix components were significantly increased. Such factors could help us to anticipate the increased risk of hemorrhages. Highlights: The levels of VEGF, MMP 9, Ang2, TGF-β1 and PDGF-BB in the arterial and venous blood were analyzed. The most significant results were obtained from the peripheral venous blood samples. The results obtained show that there is an imbalance in the angiogenesis factors in patients with rebleeding CSDH. Such a profile of factors could help us to anticipate the increased risk of hemorrhages.

Abstract
OBJECTIVE The optimal treatment for inhomogeneous chronic subdural hematoma (CSH) remains unclear. This study thus aimed to compare single burr hole drainage with minicraniotomy in the treatment of inhomogeneous CSH, including complication and recurrence rates. METHODS The clinical and radiologic data of 240 patients with inhomogeneous CSH who underwent surgery between January 2005 and January 2021 were retrieved. A total of 111 patients were included in this study. Clinical and radiological outcomes were compared between the groups undergoing different surgery types. RESULTS A total of 102 (91.8%) patients showed clinical improvement after surgery; 81 (93.1%) and 21 (87.5%) patients showed improvements in clinical symptoms in the single burr hole and minicraniotomy groups, respectively. A total of 102 (91.9%) patients showed favorable radiological findings after the surgery, including inhomogeneous CSH disappearance in 64 (73.6%) burr hole and 13 (54.2%) minicraniotomy patients, and inhomogeneous CSH improvement in 17 (19.5%) burr hole and 8 (33.3%) minicraniotomy patients. There were no significant differences in the patient characteristics or surgical outcomes between the groups. CONCLUSION Single burr hole drainage showed a slightly better improvement in clinical and radiologic findings and lower recurrence and complication rates than minicraniotomy. There were no statistically significant differences between the two groups.

Abstract
INTRODUCTION A chronic subdural haematoma (cSDH) is a collection of altered blood products between the dura and brain resulting in a slowly evolving neurological deficit. It is increasingly common and, in high income countries, affects an older, multimorbid population. With changing demographics improving the care of this cohort is of increasing importance. METHODS We convened a cross-disciplinary working group (the 'Improving Care in Elderly Neurosurgery Initiative') in October 2020. This comprised experts in neurosurgical care and a range of perioperative stakeholders. An Implementation Science framework was used to structure discussions around the challenges of cSDH care within the United Kingdom. The outcomes of these discussions were recorded and summarised, before being circulated to all attendees for comment and refinement. RESULTS The working group identified four key requirements for improving cSDH care: (1) data, audit, and natural history; (2) evidence-based guidelines and pathways; (3) shared decision-making; and (4) an overarching quality improvement strategy. Frequent transfers between care providers were identified as impacting on both perioperative care and presenting a barrier to effective data collection and teamworking. Improvement initiatives must be cognizant of the complex, system-wide nature of the problem, and may require a combination of targeted trials at points of clinical equipoise (such as anesthetic technique or anticoagulant management), evidence-based guideline development, and a cycle of knowledge acquisition and implementation. CONCLUSION The care of cSDH is a growing clinical problem. Lessons may be learned from the standardised pathways of care such as those as used in hip fracture and stroke. A defined care pathway for cSDH, encompassing perioperative care and rehabilitation, could plausibly improve patient outcomes but work remains to tailor such a pathway to cSDH care. The development of such a pathway at a national level should be a priority, and the focus of future work.

Abstract
Background Chronic subdural hematoma (CSDH) is the anomalous and encapsulated accumulation of fluid of complex origin consisting of old blood, mostly or totally liquified and cerebrospinal fluid (CSF) in the subdural space usually after a head injury in the elderly. Almost all the research on surgical techniques and endoscopic assisted evacuation of CSDH focused on the just the evacuation and not abnormal anatomical structures that causes recurrences. Objectives We investigated abnormal anatomical structures that triggers recurrence of CSDH during craniotomy as well as burr-hole craniostomy with endoscopic assistance. Materials and methods We retrospectively analyzed all patients with CSDH who underwent craniostomy and burr-hole craniotomy with endoscopic assisted evacuation of hematoma between April 2017 and November 2020 at our institution. Clinical data obtained was categorized into patient-related, radiology as well as surgery and endoscopic evaluations. Results A total of 143 patients (109 men and 34 women) aged 43–94 years (mean age, 68.35 years) with CSDH were included in this study. We observed a recurrence rate of 4.9% (7/143). Recurrences occurred between 2 and 6 months after the operation in patients with recurrences. Our data revealed that, age, hypertension, history of injury, diabetes, antiplatelet or anticoagulant use were not associated with hematoma recurrence. Nevertheless, all the patients with recurrence of hematoma were males. Interestingly, our univariate and multivariate analyses found neomembrane thickness and hematoma cavity separation as independent risk factors (OR,45.822; 95% CI,2.666-787.711; p = 0.008) for the recurrence of CSDH (p < 0.05). Also, we observed thickened membranes connecting/separating the dura and the thickened arachnoid/pia matters in all the 7 patients with hematoma recurrence. Conclusions The treatment of patients with CSDH ought to include the identification and resection of abnormal thickened membranes connecting/separating the dura and the thickened arachnoid/pia matters to avoid recurrence. Comparatively, endoscopy showed hematoma cavity separation or neomembrane thickness just as seen during craniotomy.

Abstract
Background Given the men's predominance in the prevalence of chronic subdural hematoma (CSDH), we investigated the relationship between sex differences and clinical features of CSDH. Methods We retrieved a large collection of clinical factors from CSDH patients between August 2011 and May 2019, and analyzed the differences and similarities in the clinical data and outcomes between men and women. Results In total 1,307 CSDH patients were enrolled in this study. When we did not account for age, a greater proportion of women relative to men manifested diabetes (p = 0.001) and cardiac disease (p = 0.035) prior to the onset of CSDH. Regarding recovery outcome and recurrence rate, we observed no significant differences between men and women. The sole difference between women and men after surgery was that women experienced more complications than men (p = 0.044), and both length of hospital stay (p < 0.001, B = 0.159, Exp [B] = 1.172, 95% CI = 1.078–1.274) and the presence of cardiac disease (p = 0.002, B = 2.063, Exp [B] = 7.867, 95% CI = 2.167–28.550) were identified as independent risk factors. After accounting for age, women with CSDH exhibited more frequent disorders of consciousness at admission than men in group of ≤ 40-year-old patients (p = 0.018), while proportion of women with diabetes was higher than that of men in 41–79 year-old group (p < 0.001). However, women after surgery experienced more complications (p = 0.047), longer length of hospital stays (p = 0.005), and higher mortality at discharge (p = 0.035) than men in middle-aged group. Finally, length of hospital stay (p < 0.001, B = 0.186, Exp [B] = 1.205, 95% CI = 1.091–1.331) and cardiac disease (p = 0.017, B = 2.040, Exp [B] = 7.693, 95% CI = 1.430–41.372) impacted occurrence of complications in women 41–79-year-old, while duration of drainage catheter use (p < 0.001, B = 1.132, beta = 0.280) and complications (p < 0.001, B = 5.615, beta = 0.366) were identified as independent risk factors for length of hospital stay in the same group of women. Conclusions Although sex differences did not constitute a crucial factor in all the CSDH patients, we still need to pay closer attention to disparities between men and women with respect to complications, length of hospital stay, and mortality at discharge in the various age groups (particularly with respect to 41–79 year-old women patients), to provide satisfactory management and treatment of CSDH patients.

Abstract
Objective This study systematically reviews the clinical efficacy and safety of twist-drill craniostomy with hollow screws in chronic subdural hematoma treatment. Methods A computerized search of PubMed, Embase, Web of Science, Cochrane Library, World Health Organization International Trial Registry platform, CBM, CNKI, and Wanfang Database was performed to retrieve randomized controlled trials or case-control trials using twist-drill craniostomy (TDC) with hollow screws for the evacuation of chronic subdural hematoma from the date of databases' inception to July 2021. Two investigators independently screened the studies and extracted data in strict accordance with pre-established inclusion and exclusion criteria. RevMan 5.3 software or STATA was used for meta-analysis after evaluating the methodological quality of the included studies. Results A total of 4 randomized controlled trials and 16 case-control trials with a total of 2,536 cases were included. Results of the meta-analysis showed that the surgical success rate and postoperative recurrence rate of TDC with hollow screws were slightly higher compared to the burr hole craniostomy (BHC) group, but showed no statistical significance (RR = 1.03, P = 0.05; RR = 1.13, P = 0.50). However, subgroup analysis showed that the use of YL-1 needle had a higher success rate and lower recurrence rate (RR = 1.05, P = 0.02 < 0.05; RR = 0.584, P = 0.002), and TDC with hollow screws had a lower incidence rate of postoperative complications and postoperative acute intracranial hemorrhage compared with BHC, also revealing an overall shorter hospital stay (RR = 0.57, P = 0.0002 < 0.05; RR = 0.584, P = 0.027 < 0.05; WMD = −3.752, P < 0.001). However, the postoperative mortality rate was practically the same between the two groups (OR = 1.01, P = 0.95 > 0.05). Conclusion Twist-drill craniostomy with hollow screws is not inferior or superior to BHC in efficacy, and this strategy is safer and minimally invasive, which is reflected in a lower incidence of acute intracranial hemorrhage, overall complication rate, and length of hospital stay.

Abstract
RATIONALE Symptoms of chronic subdural hematoma (CSDH) vary widely, including transient neurological deficit(s) (TND). The precise prevalence and the clinical aspects of TND are yet to be determined. Most TNDs are regarded and treated as symptomatic seizures, but the rationale for this decision is not always clear. METHODS Patients with temporary symptoms were selected from a retrospective cohort of CSDH patients. We analyzed the association of TND characteristics with patients being classified as having a symptomatic seizure and with functional outcome using logistic regression analysis. RESULTS Of the included 1307 CSDH patients, 113 (8.6%) had at least one episode of TND. Most common TNDs were aphasia/dysphasia, impaired awareness or clonic movements. Of these 113 patients, 50 (44%) were diagnosed with symptomatic seizure(s) by their treating physician. Impaired awareness, clonic movements and the presence of 'positive symptoms' showed the strongest association with the diagnosis symptomatic seizure (OR 36, 95% CI 7.8-163; OR 24, 95% CI 6.4-85; and OR 3.1, 95% CI 1.3-7.2). Aphasia/dysphasia lowered the chance of TND being classified as symptomatic seizure together with a longer TND duration (OR 0.2, 95% CI 0.1-0.6; and OR 0.91, 95% CI 0.84-0.99). Treatment with anti-epileptic drugs was related to unfavorable functional outcome (aOR 5.4, 95% CI 1.4-20.7). CONCLUSION TND was not a rare phenomenon in our cohort of CSDH patients. A TND episode of 5 min, aphasia/dysphasia and/or absence of 'positive' symptoms are suggestive of a different TND pathophysiology than symptomatic seizures. Our results further suggest that treatment of TND in CSDH deserves careful consideration as management choices might influence patient outcome.

Abstract
Objective Chronic subdural hematoma (CSDH) is a common disease in neurosurgical departments, but optimal perioperative management guidelines have not yet been established. We aimed to assess the current clinical management and outcomes for CSDH patients and identify prognostic factors for CSDH recurrence.
Methods We enrolled a total of 293 consecutive patients with CSDH who underwent burr hole craniostomy at seven institutions in 2018. Clinical and surgery-related characteristics and surgical outcomes were analyzed. The cohort included 208 men and 85 women.
Results The median patient age was 75 years. Antithrombotic agents were prescribed to 105 patients. History of head trauma was identified in 59% of patients. Two hundred twenty-seven of 293 patients (77.5%) had unilateral hematoma and 46.1% had a homogenous hematoma type. About 70% of patients underwent surgery under general anesthesia, and 74.7% underwent a single burr hole craniostomy surgery. Recurrence requiring surgery was observed in 17 of 293 patients (5.8%), with a median of 32 days to recurrence. The postoperative complication rate was 4.1%. In multivariate analysis, factors associated with CSDH recurrence were separated hematoma type (odds ratio, 3.906; p=0.017) and patient who underwent surgery under general anesthesia had less recurrence (odds ratio, 0.277; p=0.017).
Conclusion This is the first retrospective multicenter generalized cohort pilot study in the Republic of Korea as a first step towards the development of Korean clinical practice guidelines for CSDH. The type of hematoma and anesthesia was associated with CSDH recurrence. Although the detailed surgical method differs depending on the institution, the surgical treatment of CSDH was effective. Further studies may establish appropriate management guidelines to minimize CSDH recurrence.

Abstract
BACKGROUND Chronic subdural hematoma (cSDH) is a form of intracranial hemorrhage common in older adults. Optimal treatment remains controversial. We conducted a systematic review to identify surgical thresholds, characterize outcomes, and delineate critical considerations in the surgical management of older adults in order to summarize the evidence supporting the best contemporary management of cSDH. METHODS A systematic review exploring surgical management of cSDH among individuals aged 65 years and older was conducting by searching the PubMed, Embase, and Scopus databases for articles in English. Abstracts from articles were read and selected for full-text review according to a priori criteria. Relevant full-text articles were analyzed for bibliographic data, aim, study design, population, interventions, and outcomes. RESULTS Of 1473 resultant articles, 21 were included. Surgery rationale was case-by-case for symptomatic patients with cSDH. Surgery was superior to conservative management and promoted equivalent neurologic outcomes and rates of complications. Recurrence and reoperation rates in older adults were similar to younger individuals. Some studies reported higher mortality rates for older adults, while others reported no difference. Anticoagulation or antiplatelet agent use did not seem to be associated with poorer outcomes in older adults. CONCLUSIONS Surgery for cSDH in older adults leads to favorable neurologic outcomes without increased risk of overall complications, recurrence, or reoperation compared to younger patients. However, older adults may be at increased risk for mortality after surgery. It is important to determine use of anticoagulant or antiplatelet agents in older adults to optimally manage patients with cSDH.

Abstract
Background There is no consensus among clinicians regarding recommencement of antithrombotic agents following conservative management of a Chronic Subdural Hematoma (cSDH). Thus, the primary objective of this study was to determine the most commonly recommended interval and whether the data reveal a general consensus that should be adopted. Methods A retrospective analysis of Salford Royal Foundation Trust's Neurosurgical referral database for patients referred with a cSDH between March 2017 and March 2020 was carried out. Patients were sorted by whether they were on blood-thinning medications. Results Over the 3-year period, there were a total of 1220 referral and 1099 patients. 502 (41.14%) of these referrals and 479 (43.59%) patients were on one more blood thinning agent. Of these patients 221 (46.13%) conservative management, there was a clear male predominance (M: F ≈ 2.5:1) in this cohort. 2 weeks was the most commonly advised time-frame (n = 76, 36.36%) to withhold. Of the 234 referrals, there were 13 (5.88%) re-referrals in total. Crucially, there was no significant difference in reaccumulation rates between patients asked to withhold their blood thinners for 2 weeks versus those asked to stop for longer than 2 weeks (P = 0.57). Conclusion For the majority of bleeds, there is no clear benefit from asking patients to withhold their anticoagulant/antiplatelet for longer than 2 weeks. In cases, where it is deemed appropriate to stop for longer than 2 weeks, clear instructions should be provided and documented along with reasons behind the decision.

Abstract
OBJECTIVE Endovascular embolization using non-adhesive agents (e.g., ethylene vinyl alcohol copolymer with suspended micronized tantalum dissolved in dimethyl sulfoxide; Squid, Balt Extrusion) is an established treatment of brain arteriovenous malformations, dural arteriovenous fistulas, and hypervascular neoplasms. Middle meningeal artery (MMA) embolization is a relatively new concept for treating chronic subdural hematomas (CSDH). This study aimed to evaluate the safety and effectiveness of the use of Squid in the endovascular treatment of CSDH. METHODS Embolization was offered to patients with CSDH with minimal or moderate neurological deficits and patients who had previously undergone open surgery to evacuate their CSDH without a significant effect. Distal catheterization of the MMA was followed by embolization of the hematoma capsule with Squid 12 or Squid 18. Safety endpoints were ischemic or hemorrhagic stroke and any other adverse event of the endovascular procedure. Efficacy endpoints were the feasibility of the intended procedure and a ≥ 50% reduction of the maximum depth of the CSDH confirmed by follow-up computed tomography (CT) after >3 months. RESULTS Between November 2019 and July 2021, 10 patients (3 female and 7 male, age range 42-89 years) were enrolled. Five patients had bilateral hematomas, and five patients had previously been operated on with no significant effect and recurrent hematoma formation. The attempted embolization was technically possible in all patients. No technical or clinical complication was encountered. During a post-procedural follow-up (median 90 days), 10 patients improved clinically. A complete resolution of the CSDH was observed in 10 patients. The clinical condition of all enrolled patients during the so-far last contact was rated mRS 0 or 1. CONCLUSION A distal catheterization of the MMA for the endovascular embolization of CSDH with Squid allowed for the devascularization of the MMA and the dependent vessels of the hematoma capsule. This procedure resulted in a partial or complete resolution of the CSDH. Procedural complications were not encountered.

Abstract
Objective The traditional methods for managing symptomatic chronic subdural hematoma (CSDH) at our hospital include evacuation via single burr-hole irrigation with continuous closed subdural drainage (SBID). The single burr-hole aspiration and irrigation technique with continuous closed subdural drainage (SBAID) is an attractive alternative method. The goal of this study was to evaluate the radiographic and clinical outcomes of SBAID compared with traditional SBID methods. Methods A database of 51 CSDH patients treated with the SBAID method and 35 CSDH patients treated with the SBID method was compiled, and a retrospective chart review was performed. Information regarding demographics, comorbidities, presenting symptoms, and outcomes were collected. Predictors of recurrence requiring reoperation and other outcomes were analyzed. Results Compared to the patients in the SBID group, the patients in the SBAID group had a shorter mean duration of surgery (56.6±5.6 minutes vs 59.5±4.8 minutes, respectively, P=0.02); a shorter mean interval from procedure to discharge (6.2±1.2 days vs 6.8±1.3 days, respectively, P=0.046); no significant difference in preoperative hematoma volume (106.4±21.7 cm3 vs 101.3±16.3 cm3, respectively, P=0.25); and a smaller subdural space volume 48 hours after the operation (43.6±7.4 cm3 vs 47.4±9.1 cm3, respectively, P=0.03). In addition, symptomatic hematoma recurrence developed in one patient in the SBAID group and five patients in the SBID group (P=0.03). The in-hospital mortality rates of the SBAID and SBID groups were 2% (1 of 51) and 6% (2 of 35), respectively; this difference was not statistically significant (P=0.35). Conclusions The SBAID method results in a remarkably low recurrence rate and good outcomes. This method should be considered for patients presenting with symptomatic CSDHs.

Abstract
Middle meningeal artery (MMA) embolization has been proposed as a minimally invasive treatment for chronic subdural hematoma (cSDH). The aim of this systematic review and meta-analysis is to compare outcomes after MMA embolization versus conventional management for cSDH. We performed a systematic review of PubMed, Embase, Oxford Journal, Cochrane, and Google Scholar databases from April 1987 to October 2020 in accordance with PRISMA guidelines. Studies reporting outcomes after MMA embolization for ≥3 patients with cSDH were included. A meta-analysis comparing MMA embolization with conventional management was performed. The analysis comprised 20 studies with 1416 patients, including 718 and 698 patients in the MMA embolization and conventional management cohorts, respectively. The pooled recurrence, surgical rescue, and in-hospital complication rates in the MMA embolization cohort were 4.8% (95% CI 3.2% to 6.5%), 4.4% (2.8% to 5.9%), and 1.7% (0.8% to 2.6%), respectively. The pooled recurrence, surgical rescue, and in-hospital complication rates in the conventional management cohort were 21.5% (0.6% to 42.4%), 16.4% (5.9% to 27.0%), and 4.9% (2.8% to 7.1%), respectively. Compared with conservative management, MMA embolization was associated with lower rates of cSDH recurrence (OR=0.15 (95% CI 0.03 to 0.75), p=0.02) and surgical rescue (OR=0.21 (0.07 to 0.58), p=0.003). In-hospital complication rates were comparable between the two cohorts (OR=0.78 (0.34 to 1.76), p=0.55). MMA embolization is a promising minimally invasive therapy that may reduce the need for surgical intervention in appropriately selected patients with cSDH. Additional prospective studies are warranted to determine the long-term durability of MMA embolization, refine eligibility criteria, and establish this endovascular approach as a viable definitive treatment for cSDH.

Abstract
BACKGROUND AND PURPOSE Embolization of the middle meningeal artery for treatment of refractory or recurrent chronic subdural hematomas has gained momentum during the past few years. Little has been reported on the use of the n-BCA liquid embolic system for middle meningeal artery embolization. We present the technical feasibility of using diluted n-BCA for middle meningeal artery embolization. MATERIALS AND METHODS We sought to examine the safety and technical feasibility of the diluted n-BCA liquid embolic system for middle meningeal artery embolization. Patients with chronic refractory or recurrent subdural hematomas were prospectively enrolled from September 2019 to June 2020. The primary outcome was the safety and technical feasibility of the use of diluted n-BCA for embolization of the middle meningeal artery. The secondary end point was the efficacy in reducing hematoma volume. RESULTS A total of 16 patients were prospectively enrolled. Concomitant burr-hole craniotomies were performed in 12 of the 16 patients. Two patients required an operation following middle meningeal artery embolization for persistent symptoms. The primary end point was met in 100% of cases in which there were no intra- or postprocedural complications. Distal penetration of the middle meningeal artery branches was achieved in all the enrolled cases. A 7-day post-middle meningeal artery embolization follow-up head CT demonstrated improvement (>50% reduction in subdural hematoma volume) in 9/15 (60%) patients, with 6/15 (40%) showing an unchanged or stable subdural hematoma. At day 21, available CT scans demonstrated substantial further improvement (>75% reduction in subdural hematoma volume). CONCLUSIONS Embolization of the middle meningeal artery using diluted n-BCA and ethiodized oil (1:6) is safe and feasible from a technical standpoint. The use of a dextrose 5% bolus improves distal penetration of the glue.

Abstract
Chronic subdural hematomas (CSDHs) are a common neurological condition, whose incidence is expected to increase with an aging population. Although surgical evacuation is the mainstay of treatment, it results in a recurrence requiring reoperation (RrR) in 3-30% of cases. Recurrence is thought to be driven by a combination of inflammatory and angiogenic processes occurring within the CSDH outer membrane. Pathological specimens of 72 primary CSDHs were examined for eosinophilic infiltrate. For each case, the pre-operative computed tomography (CT) scan was graded according to the Nakaguchi grading scheme as homogeneous, laminar, separated, or trabecular. Rate of RrR was compared based on eosinophilic infiltrate and CT grade. A dense eosinophilic infiltrate was observed in 22% of specimens. The rate of RrR among specimens with a dense eosinophilic infiltrate was 0%, whereas it was 14.3% among specimens without a dense eosinophilic infiltrate. Incidence among homogeneous, laminar, separated, and trabecular CT subtypes was 4%, 27%, 58%, and 24%, respectively. A dense eosinophilic infiltrate found within the outer membrane of a CSDH may be a marker of hematoma maturation, signaling a transition toward healing and fibrosis, and a lower risk of RrR.

Abstract
INTRODUCTION chronic subdural hematoma (cSDH) is not uncommon in sub-Saharan Africa and has a striking morbidity and mortality if not managed adequately. With the limited number of neurosurgeons in resource poor countries, general surgeons should be trained in the skills of craniotomy and burr-hole craniostomy. METHODS we conducted a retrospective review of all medical records of patients with cSDH, who underwent flap craniotomy at the Choithrams Memorial Hospital, Sierra Leone, between January 2016 and March 2018. The case notes, operative records and computerized axial tomography (CT) scans were reviewed and all pertinent data extracted. All patients were jointly managed post operatively by medical (neurological) and surgical teams in an intensive care unit. RESULTS a total of 23 patients had surgical drainage of the chronic subdural hematoma. The mean age of the patients was 65.8 years (ranging from 54-78) with a male: female ratio of 3: 2: 1. The main predisposing risk factors were head trauma (60.9%) and antiplatelet medications (21.7%). Hypertension was the most common comorbidity, followed by diabetes mellitus. Ten (62.5%) out of sixteen patients referred for Head CT-scan by the primary physicians, had an initial missed clinical diagnosis until computerized tomography (CT) scan confirmation report of chronic subdural hematoma (cSDH) was obtained. Flap craniotomy under general anesthesia with a subdural drainage left in situ (100%) was done for all patients. Mean duration of Intensive Care Unit (ICU) admission was 10.6 days (range 6-16 days). Twenty-one (91.3%) patients made a full recovery. There was no mortality. CONCLUSION flap craniotomy for cSDH was safely performed by a traumatologist/general surgeon in a developing country where there is no neuro-surgical service. The outcome of the patients was favorable as there was co-management with the surgical and medical team.

Abstract
BACKGROUND Chronic subdural haematoma (cSDH) is a common neurosurgical pathology frequently occurring in older patients. The impact of population ageing on cSDH caseload has not been examined, despite relevance for health system planning. METHODS This is a single-centre study from the UK. Operated cases of cSDH (n = 446) for 2015-2018 were identified. Crude and directly standardised incidence rates were calculated. Medline and EMBASE were systematically searched to identify studies reporting on the incidence of cSDH by year, so an estimate of rate of incidence change could be determined. Local incidence rates were then applied to population projections for local catchment area to estimate operated cSDH numbers at 5 yearly intervals due to shifting demographics. RESULTS We identified nine studies presenting incidence estimates. Crude estimates for operative cases ranged from 1.3/100,000/year (1.4-2.2) to 5.3/100,000/year (4.3-6.6). When non-operated cases were included, incidence was higher: 8.2/100,000/year (6.0-11.2) to 48/100,000/year (37.7-61.1). Four pairs of studies demonstrated incidence rate increases of 200-600% over the last 50 years, but data was deemed too heterogeneous to generate formal estimate of incidence change. Local crude incidence of operated cSDH was 3.50/100,000/year (3.19-3.85). Directly standardised incidence was 1.58/100,000/year (1.26-1.90). After applying local incidence rates to population projections, case numbers were predicted to increase by 53% over the next 20 years. CONCLUSIONS The incidence of cSDH is increasing. We project a 53% increase in operative caseload within our region by 2040. These are important findings for guiding future healthcare planning.

Abstract
Background To investigate predictors of postoperative acute intracranial hemorrhage (AIH) and recurrence of chronic subdural hematoma (CSDH) after burr hole drainage. Methods A multicenter retrospective study of patients who underwent burr hole drainage for CSDH between January 2013 and March 2019. Results A total of 448 CSDH patients were enrolled in the study. CSDH recurrence occurred in 60 patients, with a recurrence rate of 13.4%. The mean time interval between initial burr hole drainage and recurrence was 40.8 ± 28.3 days. Postoperative AIH developed in 23 patients, with an incidence of 5.1%. The mean time interval between initial burr hole drainage and postoperative AIH was 4.7 ± 2.9 days. Bilateral hematoma, hyperdense hematoma and anticoagulant drug use were independent predictors of recurrence in the multiple logistic regression analyses. Preoperative headache was an independent risk factor of postoperative AIH in the multiple logistic regression analyses, however, intraoperative irrigation reduced the incidence of postoperative AIH. Conclusions This study found that bilateral hematoma, hyperdense hematoma and anticoagulant drug use were independently associated with CSDH recurrence. Clinical presentation of headache was the strongest predictor of postoperative AIH, and intraoperative irrigation decreased the incidence of postoperative AIH.

Abstract
Background Chronic subdural hematoma (CSDH) is a common neurological condition; surgical evacuation is the mainstay of treatment for symptomatic patients. No clear evidence exists regarding the impact of timing of surgery on outcomes. We investigated factors influencing time to surgery and its impact on outcomes of interest. Methods Patients with CSDH who underwent burr-hole craniostomy were included. This is a subset of data from a prospective observational study conducted in the UK. Logistic mixed modelling was performed to examine the factors influencing time to surgery. The impact of time to surgery on discharge modified Rankin Scale (mRS), complications, recurrence, length of stay and survival was investigated with multivariable logistic regression analysis. Results 656 patients were included. Time to surgery ranged from 0 to 44 days (median 1, IQR 1–3). Older age, more favorable mRS on admission, high preoperative Glasgow Coma Scale score, use of antiplatelet medications, comorbidities and bilateral hematomas were associated with increased time to surgery. Time to surgery showed a significant positive association with length of stay; it was not associated with outcome, complication rate, reoperation rate, or survival on multivariable analysis. There was a trend for patients with time to surgery of ≥7 days to have lower odds of favorable outcome at discharge (p=0.061). Conclusions This study provides evidence that time to surgery does not substantially impact on outcomes following CSDH. However, increasing time to surgery is associated with increasing length of stay. These results should not encourage delaying operations for patients when they are clinically indicated.

Abstract
Background Chronic subdural hematoma (CSDH) is predominantly a disease of the elderly. Objectives This article studies the clinical and radiological outcomes in patients with CSDH who had undergone bedside percutaneous twist drill craniostomy (TDC). Patients and Methods A retrospective study was conducted in 80 patients who had undergone percutaneous TDC for CSDH between January 2017 and December 2018. Patients between 18 and 90 years of age were selected. CSDH showing computed tomography (CT) scan findings of homogeneous hypodensity, homogeneous isodensity, mixed density, and CSDH with hyperdense gravity-dependent fluid level were selected. CT evidence of multiple septations, recurrent CSDH, bilateral CSDH, and acute on CSDH were excluded. The presence of midline shift (MLS) was measured as any deviation of the septum pellucidum from the midline. The mass effect was determined by the effacement of the sulci, Sylvian fissure obscuration, or compression of lateral ventricles. Postoperative decrease in the signs and symptoms were considered as the postoperative clinical improvement. Improvement in the postoperative CT scan was determined by the decrease in the thickness of CSDH and absence of MLS with decrease in the mass effect. The presence of the CSDH with mass effect and MLS was considered as the significant residue in the postoperative CT scan. Statistical Analysis Statistical analysis is done using Epi Info software. Results The mean age range was 67.78 years ± 12.03 standard deviation (SD). There were 49 (61.25%) males and 31 (38.75%) females. Thirty-eight (47.5%) CSDHs were on the right side and 42 (52.5%) on the left side. The locations were in the frontotemporoparietal region in 91.25% patients and in the frontoparietal region in 8.75% patients. The mean duration of symptoms was 4.62 days ± 5.20 SD. History of trauma was present in 58.75% patients. The mean duration of trauma was 45.78 days ± 28.32 SD. The most common symptoms were weakness of the limbs (68.75%), altered sensorium or decreased memory (52.5%), and headache (32.5%). The preoperative Glasgow Coma Scale (GCS) score ranged from 4 to 15 (mean 12.86 ± 2.98 SD). Limb motor weakness was noted in 75% patients. The maximum thickness of the CSDH (in millimeter) in axial CT scan was 8 to 32 (mean 23.22 ± 4.87 SD). All of the 80 patients had MLS. Postoperative GCS ranged from 3 to 15 (mean 14.1 ± 2.78 SD). Postoperative power was improved in 95% of affected limbs. Postoperative power was deteriorated (including patients of complications and death) in 5% patients. Clinical improvement was noted in 93.75% patients. Postoperative CT scan improvement was noted in 95% patients. Two patients (2.5%) had significant residue which required reoperation. Two patients (2.5%) developed extradural hematoma which was operated. Five (6.25%) patients developed complications, among which 4 (5%) patients died. The mean duration of stay in the hospital was 6.82 days ± 4.16 SD. Conclusions CSDH is a disease of elderly population. CSDH is more common in male population. The most common symptom is weakness of the limbs. High clinical and radiological improvement can be achieved with TDC. TDC should be considered as a safe and effective alternative to burr hole craniostomy.

Abstract
Background Chronic subdural hematoma (CSDH) is predominantly a disease of the elderly. On accounting its risk-to-benefit ratio, there was always controversy regarding the management of the CSDH as to which procedure is superior. Aims The aim is to compare the clinical and radiological outcomes in patients of CSDH who have undergone single burr-hole craniostomy (BHC) versus twist-drill craniostomy (TDC). Patients and Methods A retrospective study was conducted in patients admitted with CSDH who had undergone single BHC or TDC between January 2014 and December 2016. Patients between 18 and 90 years of age were selected. Patients with CSDH showing computed tomography (CT) scan findings of homogeneous hypodensity, homogeneous isodensity, and mixed density were selected. CT scan findings of CSDH with hyperdense gravity-dependent fluid level were also selected. Patients with CT evidence of multiple septations were excluded from the study. Recurrent CSDH, bilateral CSDH, and CSDH with secondary acute bleed were also excluded. Diagnosis was done using noncontrast CT scan. The maximum thickness of the CSDH was measured in the axial film of CT scan. The presence of midline shift (MLS) was measured as any deviation of the septum pellucidum from the midline in axial CT film. The mass effect was determined by the effacement of the sulci, sylvian fissure obscuration, or compression of lateral ventricles. The decrease in the signs and symptoms in postoperative period was considered as the postoperative clinical improvement. Improvement in the postoperative CT scan was determined by the decrease in the thickness of CSDH and absence of the MLS with decrease in the mass effect. The presence of the CSDH with mass effect and MLS was considered as the significant residue in the postoperative CT scan. Patients with significant residue underwent reoperation. Results There were 63 patients in BHC group and 46 patients in TDC group. The mean age in BHC and TDC groups was 61.39 ± 13.21 standard deviation (SD) and 73.36 ± 10.82 SD, respectively. There were 48 (76.19%) male and 15 (23.81%) female in BHC group. There were 32 (69.57%) male and 14 (30.43%) female in TDC group. In BHC group, 41.27% were on the right side and 58.73% on the left side. In TDC group, 50% were on the right side and 50% on the left side. In BHC group, 82.54% were in the frontotemporoparietal region, 9.52% in the frontoparietal region, 6.35% in the temporoparietal region and 1.58% in the parietooccipital region. In TDC group, 86.95% were in the frontotemporoparietal region, 8.69% in the frontoparietal region, 2.17% in the temporoparietal region, and 2.17% in the parietooccipital region. There was no significant difference in duration of symptoms and history of trauma in both the groups. The symptoms of the patients in BHC versus TDC include weakness of the limbs (44.44% vs. 73.91%), headache (50.79% vs. 32.60%), altered sensorium or decreased memory (44.44% vs. 54.4%), vomiting (19.04% vs. 6.52%), speech abnormalities (15.87% vs. 19.56%), urinary incontinence (25.39% vs. 15.21%), seizure (1.58% vs. 4.34%), and diplopia (4.76% vs. 0%). The mean preoperative Glasgow Coma Scale (GCS) score in BHC versus TDC was 13.44 ± 2.23 SD versus 12.47 ± 2.95 SD limb weakness was noted in 52.38% BHC group and 82.60% TDC group. There was significantly decreased GCS score in TDC group. The number of the patients with limb weakness on affected side was significantly more in TDC group. The mean maximum thickness of the CSDH (in millimeter) in axial CT scan was 17.22 ± 4.29 SD in BHC group and 22.21 ± 4.52 SD in TDC group. The number of patients with MLS was 59 (93.65%) in BHC group and 45 (97.82%) in TDC group. There was significant difference in thickness of CSDH in both the groups. However, there was no significant difference in MLS in both the groups. There was no significant difference in prothrombin time, International Normalized Ratio, and activated partial thromboplastin time values of both the groups. There was significant difference in platelet counts of both the groups. The mean duration of procedure (in minutes) in BHC versus TDC was 79.20 ± 26.76 SD versus 27.47 ± 4.80 SD. The duration of procedure was significantly more in BHC compared to TDC. In postoperative assessment, there was no significant difference in the GCS score, power improvement, power deterioration, clinical improvement, and improvement in CT scans of both the groups. Postoperative CSDH residue requiring reoperation was significantly more in TDC group against the BHC group (13.04% vs. 1.58%). There was no significant difference in the development of acute subdural hematoma (SDH) (4.76% vs. 8.6%), reoperation rate (6.35% vs. 17.39%), complications (9.52% vs. 15.21%), and death (4.76% vs. 10.87%) in BHC group vs. TDC group. There was no significant difference in the period of hospital stay (days) in BHC (8.90 ± 5.89 SD) and TDC groups (7 ± 4.24 SD). Conclusion The duration of procedure was significantly more in BHC than in TDC. In postoperative outcome, there was no significant difference in the GCS score, motor power improvement, motor power deterioration, overall clinical improvement, and improvement in CT scans of both the groups. Postoperative residue requiring reoperation was significantly more in TDC group. There was no significant difference in the development acute SDH, reoperation rate, complications, death, and hospital stay in both the groups. Avoiding the complications of general anesthesia and giving the equal postoperative improvement and complications of BHC, the TDC is considered as an effective alternative to the BHC in the surgical management of CSDH.

Abstract
BACKGROUND Chronic subdural haematoma (CSDH) is a common neurological disease with a rapidly rising incidence due to increasing age and widespread use of anticoagulants. Surgical intervention by burr-hole craniotomy (BHC) is the current standard practice for symptomatic patients, but associated with complications, a recurrence rate of up to 30% and increased mortality. Dexamethasone (DXM) therapy is, therefore, used as a non-surgical alternative but considered to achieve a lower success rate. Furthermore, the benefit of DXM therapy appears much more deliberate than the immediate relief from BHC. Lack of evidence and clinical equipoise among caregivers prompts the need for a head-to-head randomised controlled trial. The objective of this study is to compare the effect of primary DXM therapy versus primary BHC on functional outcome and cost-effectiveness in symptomatic patients with CSDH. METHODS/DESIGN This study is a prospective, multicentre, randomised controlled trial (RCT). Consecutive patients with a CSDH with a Markwalder Grading Scale (MGS) grade 1 to 3 will be randomised to treatment with DXM or BHC. The DXM treatment scheme will be 16 mg DXM per day (8 mg twice daily, days 1 to 4) which is then halved every 3 days until a dosage of 0.5 mg a day on day 19 and stopped on day 20. If the treatment response is insufficient (i.e. persistent or progressive symptomatology due to insufficient haematoma resolution), additional surgery can be performed. The primary outcomes are the functional outcome by means of the modified Rankin Scale (mRS) score at 3 months and cost-effectiveness at 12 months. Secondary outcomes are quality of life at 3 and 12 months using the Short Form Health Survey (SF-36) and Quality of Life after Brain Injury Overall Scale (QOLIBRI), haematoma thickness after 2 weeks on follow-up computed tomography (CT), haematoma recurrence during the first 12 months, complications and drug-related adverse events, failure of therapy within 12 months after randomisation and requiring intervention, mortality during the first 3 and 12 months, duration of hospital stay and overall healthcare and productivity costs. To test non-inferiority of DXM therapy compared to BHC, 210 patients in each treatment arm are required (assumed adjusted common odds ratio DXM compared to BHC 1.15, limit for inferiority < 0.9). The aim is to include a total of 420 patients in 3 years with an enrolment rate of 60%. DISCUSSION The present study should demonstrate whether treatment with DXM is as effective as BHC on functional outcome, at lower costs. TRIAL REGISTRATION EUCTR 2015-001563-39 .

Abstract
IMPORTANCE Elderly patients who undergo surgery for an isolated nontraumatic subdural hematoma (SDH) are at major risk for SDH reaccumulation, which can cause further injury and disability. Few population-based studies have examined how often nontraumatic SDH reaccumulates and necessitates repeated operation. OBJECTIVE To determine the rate of repeated operation after evacuation of nontraumatic SDH. DESIGN, SETTING, AND PARTICIPANTS In a cohort study, 2 parallel analyses were performed using data from the National Surgical Quality Improvement Project (NSQIP) from January 1, 2012, through December 31, 2015, and inpatient and outpatient claims data from a 5% nationally representative sample of Medicare beneficiaries from January 1, 2009, to September 30, 2015. In both samples, our cohort comprised patients 65 years or older who underwent surgical evacuation of nontraumatic SDH. Data were analyzed from March 28 to April 13, 2018. MAIN OUTCOMES AND MEASURES The outcome variable was repeated operation for SDH after the index operation. Survival analysis and Kaplan-Meier statistics were used to calculate cumulative rates. RESULTS Among 2 831 274 cases submitted to the NSQIP registry, 515 patients 65 years or older (mean [SD] age, 76.9 [7.4] years; 177 [34.4%] women; 367 [71.3%] white) who underwent craniotomy or craniectomy for nontraumatic SDH were identified. Within 30 days after the index surgery, 37 patients underwent a repeated operation for SDH. The cumulative 30-day mortality rate was 13.8% (95% CI, 11.0%-17.1%), and the repeated operation rate was 7.8% (95% CI, 5.7%-10.7%). Among a cohort of 1 952 305 Medicare beneficiaries, 1534 patients (mean [SD] age, 77.7 [7.0] years; 498 [32.5%] women; 1244 [81.1%] white) who underwent evacuation of nontraumatic SDH were identified. A total of 103 patients underwent a repeated operation within 90 days. The cumulative 30-day mortality rate was 11.6% (95% CI, 10.1%-13.3%), and the repeated operation rate was 4.9% (95% CI, 3.9%-6.2%); the cumulative 90-day mortality rate was 17.6% (95% CI, 15.7%-19.6%), and the repeated operation rate was 7.5% (95% CI, 6.2%-9.0%). The study found no evidence of a significant difference in cumulative repeated operation rates at 90 days between patients whose index surgery was a burr-hole procedure for chronic SDH (11.7%; 95% CI, 6.3%-21.3%) vs a craniotomy or craniectomy (7.2%; 95% CI, 6.0%-8.8%) (P = .14 by the log-rank test). CONCLUSIONS AND RELEVANCE In 2 large cohorts of US patients, approximately 5% to 10% of patients who underwent surgery for nontraumatic SDH were required to undergo repeated operation within 30 to 90 days. These results may inform the design of future prospective studies and trials and help practitioners calibrate their index of suspicion to ensure that patients are referred for timely surgical care.

Abstract
PURPOSE OF REVIEW Subdural hematomas (SDH) represent common neurosurgical problem associated with significant morbidity, mortality, and high recurrence rates. SDH incidence increases with age; numbers of patients affected by SDH continue to rise with our aging population and increasing number of people taking antiplatelet agents or anticoagulation. Medical and surgical SDH management remains a subject of investigation. RECENT FINDINGS Initial management of patients with concern for altered mental status with or without trauma starts with Emergency Neurological Life Support (ENLS) guidelines, with a focus on maintaining ICP < 22 mmHg, CPP > 60 mmHg, MAP 80-110 mmHg, and PaO2 > 60 mmHg, followed by rapid sequence intubation if necessary, and expedited acquisition of imaging to identify a space-occupying lesion. Patients are administered anti-seizure medications, and their antiplatelet medications or anticoagulation may be reversed if neurosurgical interventions are anticipated, or until hemorrhage is stabilized on imaging. Medical SDH care focuses on (a) management of intracranial hypertension; (b) maintenance of adequate cerebral perfusion; (c) seizure prevention and treatment; (d) maintenance of normothermia, eucarbia, euglycemia, and euvolemia; and (e) early initiation of enteral feeding, mobilization, and physical therapy. Post-operatively, SDH patients require ICU level care and are co-managed by neurointensivists with expertise in treating increased intracranial pressure, seizures, and status epilepticus, as well as medical complications of critical illness. Here, we review various aspects of medical management with a brief overview of pertinent literature and clinical trials for patients diagnosed with SDH.

Abstract
Objective: The proportion of the super-aged population (at the age of 80 or above) in patients with chronic subdural hematoma (CSDH) and the incidence of CSDH of the population have been increasing. Since it is widely accepted that YL-1 needle is effective in CSDH treatment, this paper aimed to probe into the efficacy of YL-1 needle in minimally invasive surgery for super-aged (at the age of 80–90) CSDH patients. Methods: A retrospective analysis on the clinical information of 17 super-aged CSDH patients having received the YL-1 needle puncture treatment provided by the hospital from May 2012 to December 2016 was performed. At the same time, another 19 CSDH patients (ages 60–79) who were hospitalized during the same period were randomly selected to form a control group. The same surgical treatment was provided for both groups to observe and compare the treatment efficacy. Results: The patients of both groups were cured and discharged. Among the super-aged patients, there was 1 patient with postoperative hematoma recurrence, 1 patient with pneumocephalus, and 1 patient with wound infection; among the aged patients, 1 reported postoperative recurrence and 2 had pneumocephalus; The average length of stay of the super-aged group was 9.235 ± 2.948 days while that of the aged group was 7.316 ± 3.660 days, which showed no statistical difference. Conclusion: The YL-1 needle puncture treatment is safe and efficacious for both the super-aged and the aged CSDH patients.

Abstract
BACKGROUND Chronic subdural haematoma is a common but retractable neurological disease in the elderly with a high rate of recurrence. Dexamethasone (DX) either as monotherapy or adjuvant therapy has been applied clinically, but its effectiveness and feasibility remain controversial. We conducted this review to clarify this issue. METHODS With a systematic review through multiple databases, we retrieved eligible English language publications and extracted relevant data to perform meta-analyses. The respective risk ratio (RR) and its 95% confidence interval (CI) were pooled to evaluate the overall effect. RESULTS Our meta-analysis showed overall that DX (alone or adjuvant) resulted in a lower recurrence rate when compared with non-DX therapy (RR, 0.54; 95% CI, 0.33-0.88; p = 0.01), but sensitivity analysis by excluding the most influential study achieved inconsistent results. The pooled effect revealed no statistical difference on recurrence rate between DX alone and non-DX therapy or surgical therapy (RR, 0.86; 95% CI, 0.43-1.71; p = 0.66) (RR, 0.89; 95% CI, 0.43-1.85; p = 0.76). Comparison between DX alone with the surgical therapy demonstrated no difference on the poor outcome (RR, 0.40; 95% CI, 0.15-1.04; p = 0.06). CONCLUSIONS We had no enough evidence to support DX use as an effective alternation to surgical therapy. But adjuvant DX use may facilitate the surgical therapy by reducing recurrence. Further study focusing on adjuvant DX was required.

Abstract
Objective To establish the risk of recurrence in patients with chronic subdural hematoma (cSDH) on antithrombotic treatment (AT, i.e., antiplatelets and anticoagulants). Secondary end points were perioperative morbidity and mortality between groups (AT vs. no-AT group) and exploration if timing of resumption of AT treatment (i.e., prophylactic early vs. late resumption) influenced the occurrence of thromboembolism and hematoma recurrence. Materials In a population-based consecutive cohort, we conducted a retrospective review of 763 patients undergoing primary burr hole procedures for cSDH between January 1, 2005, and December 31, 2010, at the Karolinska University Hospital, Stockholm, Sweden. Early AT resumption was ≤30 days and late >30 days after the procedure. Results A total of 308/763 (40.4%) cSDH patients were on AT treatment at the time of diagnosis. There was no difference in cSDH recurrence within 3 months (11.0% vs. 12.0%, p = 0.69) nor was there any difference in perioperative mortality (4.0% vs. 2.0%, p = 0.16) between those using AT compared to those who were not. However, perioperative morbidity was more common in the AT group compared to no-AT group (10.7% vs. 5.1%, p = 0.003). Comparing early vs. late AT resumption, there was no difference with respect to recurrence (7.0% vs. 13.9%, p = 0.08), but more thromboembolism in the late AT resumption group (2.0% vs. 7.0%, p < 0.01). Conclusion In clinical practice, cSDH patients on AT therapy at the time of diagnosis have similar recurrence rates and mortality compared to those without AT therapy, but with higher morbidity. Early resumption was not associated with more recurrence, but with lower thromboembolic frequency. Early AT resumption seems favorable, and a prospective RCT is needed.

Abstract
Background Chronic subdural hematoma (cSDH) is one of the most common conditions encountered in neurosurgical practice. Recurrence, observed in 5–30% of patients, is a major clinical problem. The temperature of the irrigation fluid used during evacuation of the hematoma might theoretically influence recurrence rates since irrigation fluid at body temperature (37 oC) may beneficially influence coagulation and cSDH solubility when compared to irrigation fluid at room temperature. Should no difference in recurrence rates be observed when comparing irrigation-fluid temperatures, there is no need for warmed fluids during surgery. Our main aim is to investigate the effect of irrigation-fluid temperature on recurrence rates and clinical outcomes after cSDH evacuation using a multicenter randomized controlled trial design. Methods The study will be conducted in three neurosurgical departments with population-based catchment areas using a similar surgical strategy. In total, 600 patients fulfilling the inclusion criteria will randomly be assigned to either intraoperative irrigation with fluid at body temperature or room temperature. The power calculation is based on a retrospective study performed at our department showing a recurrence rate of 5% versus 12% when comparing irrigation fluid at body temperature versus fluid at room temperature (unpublished data). The primary endpoint is recurrence rate of cSDH analyzed at 6 months post treatment. Secondary endpoints are mortality rate, complications and health-related quality of life. Discussion Irrigation-fluid temperature might influence recurrence rates in the evacuation of chronic subdural hematomas. We present a study protocol for a multicenter randomized controlled trial investigating our hypothesis that irrigation fluid at body temperature is superior to room temperature in reducing recurrence rates following evacuation of cSDH.

Abstract
OBJECTIVE To review the complex pathogenesis of the subdural membrane and the link between head trauma, dementia, and dural lymphatics. METHODS A thorough literature search of published English-language articles was performed using PubMed, Ovid, and Cochrane databases. RESULTS Chronic subdural hematoma (cSDH) is a common intracranial pathology and a leading cause of reversible dementia. cSDH is projected to affect at least 60,000 new individuals in the United States annually by 2030. This condition can result from mild to moderate head trauma that leads to hemorrhaging in the dura-arachnoid interface. The short-term and long-term effects of cSDH and the subdural membrane on the pathogenesis of dementia and the newly discovered dural lymphatics is a topic of increasing importance. CONCLUSIONS Further research into the possible link between traumatic brain injury and cSDH in particular and dural lymphatics and intracranial fluid dynamics is warranted.

Abstract
As the world population becomes progressively older, the overall incidence of chronic subdural hematoma (CSDH) is increasing. Peak age of onset for CSDH has also increased, and recently the 80-year-old level has a peak. Many patients with CSDH have had prior treatment with anticoagulants and antiplatelet drugs, which have an accompanying risk of CSDH. In elderly patients with CSDH, symptoms of cognitive change (memory disturbance, urinary incontinence, and decreased activity) and disturbance of consciousness at admission were more frequent compared to younger patients with CSDH. The literature actually offers conflicting advice regarding CSDH treatment; however, burr hole surgery with drainage under local anesthesia is the most common surgical procedure, even in elderly patients. The recurrence rate of CSDH has not decreased over recent decades, and it has ranged from 0.36-33.3%. Outcomes in patients over 75 years old was significantly worse than for those younger than 75. Moreover, long-term outcomes for elderly patients with CSDH are poor. CSDH in the elderly is no longer a benign disease. In the future, it will be important for us to understand the mechanisms of onset and recurrence of CSDH and to develop more effective medical treatments and noninvasive surgical techniques for elderly patients.

Abstract
OBJECTIVE Sex differences in various diseases recently have been recognized as an important factor in the approach to more efficient preventive and therapeutic medicine. We clarified sex differences in the clinical characteristics of chronic subdural hematoma (CSDH) by comparing men and women with CSDH, as there is a well-known male predominance in the prevalence of CSDH. METHODS Clinical factors and computed tomography findings were investigated retrospectively in 490 consecutive patients admitted to our hospital between 2006 and 2015 who were diagnosed with CSDH. RESULTS On univariate analysis, women were significantly older than men (P < 0.05). In women, premorbid impaired activities of daily living, consciousness disturbance, acute-to-chronic subdural hematoma, and death as outcomes at discharge were significantly more frequent than in men (P < 0.05). In contrast, women had less frequent instances of good recovery and less alcohol intake (P < 0.05). Multivariate analysis demonstrated female sex as an independent predictor of consciousness disturbance at admission. Female sex also was identified as a predictor of death at discharge. CONCLUSIONS We demonstrated sex differences in the clinical characteristics of CSDH. In the future, management of patients with CSDH with regard to sex differences in disease characteristics could be expected to improve the outcomes of women, which have been worse than in men.

Abstract
An 86-year-old woman was admitted to the intensive care unit with a chronic subdural hematoma (CSDH) and rapid onset of worsening neurological symptoms. She was taken to the operating room for a mini-craniotomy for evacuation of the CSDH including excision of the dura and CSDH membrane. Postoperatively, a subdural evacuation port system (SEPS) was integrated into the craniotomy site and left in place rather than a traditional subdural catheter drain to evacuate the subdural space postoperatively. The patient had a good recovery and improvement of symptoms after evacuation and remained clinically well after the SEPS was removed. We offer the technique of dura and CSDH membrane excision plus SEPS drain as an effective postoperative alternative to the standard craniotomy leaving the native dura intact with traditional subdural drain that overlies the cortical surface of the brain in treating patients with CSDH.

Abstract
Patients with cSDH presenting with new or worsening neurological deficits, especially if they are debilitating and adversely affecting quality of life require urgent medical and surgical attention. Neurological and neurosurgical critical care team need to stabilize the patient by reversing any underlying coagulopathy states in order to prevent further hematoma expansion.In the event of brain herniation and presumed ICP elevation and CPP compromise, step-wise ICP management should be instituted promptly.Seizure prophylaxis treatment is reasonable. Timing of surgical evacuation is not always easy to determine but the presence of significant neurological deficits with impending herniation require immediate surgical Intervention. Consideration of the clot density along with patient's current neurological status would determine the timing and type of surgical interventions. Postoperative critical care management is not trivial. In addition to detecting any changes in neurological conditions, timely initiation (typically within the first 48 hours if clinical and radiographic conditions are stable with no co-existing coagulopathy) of venous thromboembolism prophylaxis is essential. Resuming antiplatelets and anticoagulants are warranted for those with clear indications including atrial fibrillation, atrial thrombus, known deep vein thrombosis, mechanical heart valves and other preexisting hypercoagulable conditions, but it is generally advised to hold antiplatelets and anticoagulants for about 10-14 post injury and/or surgical intervention.

Abstract
Objective:To address whether to restart older patients on anticoagulants or antiplatelet agents in the setting of a chronic subdural hematoma (cSDH).Methods:This is an update of a previous review (searched until July 2012). Medline, EMBASE, ISI Web of Knowledge, Google Scholar, PLOS, and the Cochrane Register for Systematic Reviews databases were searched from January 2012 to December 2016. Studies included older adults (those over 65 years) experiencing traumatic subdural hematoma or cSDH who were on anticoagulation or antiplatelet agents.Results:Seven studies were included (mean age 72 years). Four out of 7 studies provided combined data on anticoagulants or antiplatelet use. Only one study found anticoagulant or antiplatelet agent use to be a significant factor for cSDH rebleeding. Two studies considered anticoagulant use only and both reported similar increased odds of rebleeding (odds ratio [OR] 1.75, 95% confidence interval [CI] 0.18–16.86; OR 2.7 95% CI 1.42–6.96). Antiplatelets were not found to be associated with rebleeding. Ideal timing to resume anticoagulants or antiplatelets was unclear.Conclusions:Anticoagulant medication was associated with increased rebleeding risk in older adults with cSDH. However, antiplatelet medication was not associated with increased risk of rebleeding.

Abstract
OBJECTIVE To improve quality of care for patients presenting with chronic subdural haematoma (CSDH) by introducing a multi-disciplinary integrated care pathway. SUMMARY BACKGROUND CSDH is a common neurological condition. Incidence rises with age and currently affects around 58/100 000 people over 70 years. Six-month mortality is high (26%), however integrated care pathways have been shown to improve patient outcomes in other surgical subspecialties. MATERIALS AND METHODS A baseline retrospective audit completed in 2012 identified areas for improvement in patient management. Stakeholder meetings were held with subsequent development and implementation of a patient care pathway. A post-implementation prospective audit was completed between January and October 2015. DATA COLLECTED patient demographics, medical co-morbidities, use of anti-platelet and anti-coagulant medication, timing of surgery, length of hospital stay, morbidity and mortality data, and reaccumulation rate. RESULTS Patient groups were similar with a high incidence of multi-morbidity. The key areas targeted for improvement included enhanced pre-operative optimisation and time to surgery. Implementation of the patient care pathway significantly increased the number of patients undergoing surgery within 24 hours of admission (43% vs. 75%, p = 0.0006) but length of hospital stay did not change. Operative morbidity and mortality remained similar and there was no significant difference in CSDH reaccumulation rate. CONCLUSION Our patient care pathway appears to have improved pre-operative care and significantly increased the proportion of patients undergoing surgery within 24 hours of admission. Difficulties were encountered with changing existing practice. Prospective research is required to demonstrate the full benefits, which may include a reduction in health and social care costs.

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: The aim of this retrospective study is to evaluate the efficacy and incidence of complications of craniotomy and membranectomy in elderly patients for the treatment of organized chronic subdural hematoma (OCSH). Materials and Methods: We retrospectively reviewed a series of 28 consecutive patients suffering from OCSH, diagnosed by magnetic resonance imaging (MRI) or computer tomography (CT) to establish the degree of organization and determine the intrahematomal architecture including inner membrane ossification. The indication to perform a primary enlarged craniotomy as initial treatment for nonliquefied OCSH with multilayer loculations was based on the hematoma MRI appearance – mostly hyperintense in both T1- and T2-weighted images with a hypointense web- or net-like structure within the hematoma cavity or inner membrane calcification CT appearance - hyperdense. These cases have been treated by a large craniotomy with extended membranectomy as the initial treatment. However, the technique of a burr hole with closed system drainage for 24–72 h was chosen for cases of nonseptated and mostly liquefied Chronic Subdural Hematoma (CSDH). Results: Between 1998 and 2015, 148 consecutive patients were surgically treated for CSDH at our institution. Of these, 28 patients which have OSDH underwent a large craniotomy with extended membranectomy as the initial treatment. The average age of the patients was 69 (69.4 ± 12.1). Tension pneumocephalus (TP) has occurred in 22.8% of these patients (n = 28). Recurring subdural hemorrhage (RSH) in the operation area has occurred in 11.9% of these patients in the first 24 h. TP with RSH was seen in 4 of 8 TP patients (50%). Large epidural air was seen in one case. Postoperative seizures requiring medical therapy occurred in 25% of our patients. The average stay in the department of neurosurgery was 11 days, ranging from 7 to 28 days. Four patients died within 28 days after surgery; mortality rate was 14.28%. Conclusion: Large craniotomy and extended membrane excision for OSDH still carry a high rate of mortality and morbidity in elderly patients. TP, RSH, and postoperative seizures are frequently seen complications in elderly patients.

Abstract
The etiology of chronic subdural hematoma (CSDH) in patients is diverse. The primary objective of this article was to discuss one of the causes, spontaneous intracranial hypotension with spinal cerebrospinal fluid (CSF) leak, which is usually neglected by the neurosurgeon. All the consecutive 15 patients who underwent operation for CSDHs between June 2012 and June 2014 at Sir Run Run Shaw Hospital of Zhejiang University were included in this retrospective cohort study. The clinical and imaging data of these patients with CSDHs due to spinal CSF leak were retrospectively studied. Fifteen patients, with a mean age of 53.8 ± 8.3 years, underwent operations for CSDH. Hematomas were unilateral in 4 patients and bilateral in 11 patients. Among these patients, eight patients had recurrence of hematomas after operation due to neglect of spinal CSF leak. All patients had fully recovery. Spinal CSF leak is a cause of cSDH, which is overlooked by the doctor.

Abstract
BACKGROUND Chronic subdural hematoma (CSDH) is a common neurosurgical condition with an increasing incidence. Standard treatment of CSDHs is surgical evacuation. The objective of this study is to present a modification of standard burr-hole hematoma evacuation using a flexible endoscope and to assess the advantages and risks. METHODS Prospectively, 34 consecutive patients diagnosed with CSDH were included in the study. Epidemiological, clinical and radiographical data were collected and reviewed. All patients underwent a burr-hole evacuation of CSDH. A flexible endoscope was inserted and subdural space inspected during surgery. The surgeon was looking specifically for the presence of septations, draining catheter position and acute bleeding. RESULTS Thirty-four patients underwent 37 endoscope-assisted surgeries. Presenting symptoms were hemiparesis (79%), decreased level of consciousness (18%), gait disturbances (15%), headache (12%), aphasia (6%), cognitive disturbances (6%) and epileptic seizure (3%). Average operative time was 43 min, and the average increase in operative time due to the use of the endoscope was 6 min. Recurrence rate was 8.8%, and clinical outcome was favorable (defined as mRS ≤ 2) in 97% of the cases. CONCLUSIONS To our knowledge, the present cohort of 34 patients is the largest group of patients with CSDH treated using an endoscope. This technique allows decent visualization of the hematoma cavity while retaining the advantages of a minimally invasive approach under a local anesthesia. The main advantages are correct positioning of the catheter under visual control, identification of septations and early detection of cortex or vessel injury during surgery.
