Abstract
The aim of the study was to evaluate radiographic clearance and clinical outcomes in patients over age 80 who undergo SQUID 18 embolization of the middle meningeal artery (MMA) for the management of chronic subdural hematoma (cSDH). From April 2020 to October 2021, data were obtained from patients with cSDH who underwent MMA embolization at our institution. Clinical and radiological data including pre-operative and last follow-up CT scans were analyzed. Six embolization procedures were performed in five patients using SQUID 18, a liquid embolic agent. The median age was 83 years, and three subjects were female. Two of the six cases were recurrent hematomas. MMA embolization was achieved in 100% of cases. The median diameter of the hematoma at admission was 20 mm and at last follow-up was 5.3 mm, demonstrating statistically significant radiographic clearance (P = 0.043). There were no intra or post-operative complications. Mortality was not noted during observation period. SQUID MMA embolization safely and significantly reduced the hematoma diameter and offers an alternative treatment in patients older than 80 years with cSDH.

Cost Comparison for Open Surgery versus Middle Meningeal Artery Embolization in Patients with Chronic Subdural Hematomas: A Propensity Score-Matched Analysis. World Neurosurg 2023; 172:e94-e99. [PMID: 36549437 DOI: 10.1016/j.wneu.2022.12.042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2022] [Accepted: 12/09/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND Chronic subdural hematoma (cSDH) can be treated with conventional surgery or middle meningeal artery embolization (MMAE). The cost profiles of open surgery versus MMAE have never been studied. Therefore, we sought to compare the costs of surgical and MMAE treatment of cSDH. METHODS Patients treated with open surgery (2006-2019) and MMAE (2018-2020) were identified from the institutional database. Propensity score matching analysis was used to assemble a balanced group of subjects. Detailed hospitalization costs in each group were collected and compared. RESULTS A total of 341 conventionally treated and 52 MMAE cases were identified. After propensity score matching, 33 patients were included in each group, for a total of 66 patients for analysis. Direct procedural cost was significantly greater in the MMAE group compared with the open surgery group ($38,255 ± $11,859 vs. $11,206 ± $7888; P < 0.001). Medication cost also was greater in the MMAE group ($6888 ± $6525 vs. $4291 ± $3547; P = 0.048). No significant difference was found in costs for intensive care unit care, pharmacy, therapy, laboratory values, and the emergency department. Imaging costs and other miscellaneous costs (e.g., wound care, preoperative, and postanesthesia care unit) were greater in the open surgery group (P < 0.05). Total hospitalization cost was not significantly different between the 2 groups ($60,598 ± 61,315 vs. $71,569 ± $37,813 for open surgery and MMAE respectively, P = 0.385). No significant differences in number of follow ups or total costs for follow up were found (P > 0.05). CONCLUSIONS Open surgery and MMAE offer an overall equivalent cost-profile for cSDH treatment when matching for potential cost confounders. Direct procedural costs are greater in MMAE; however, total hospitalization costs and follow up costs are not significantly different.

Abstract
INTRODUCTION Chronic subdural hematoma (CSDH) often occurs 3 weeks to 3 months after brain injury, which is mainly caused by bleeding of the bridging vein. For patients with ventriculoperitoneal (V-P) shunt, excessive drainage can also cause CSDH. We present a rare case of CSDH caused by shunt valve breakdown in brain injury. CASE REPORT We report a 68-year-old man with V-P shunt for 8 years. He presented with bilateral CSDH with disappearance of lateral ventricles nearly 1 month after a brain injury caused by being hit with a stick. After burr hole drainage (BHD), the patient's symptoms improved and lateral ventricles reappeared, but disappeared rapidly with CSDH recurrence within a short time. We considered the cause to be medium pressure shunt valve breakdown caused by hitting with a stick, which was confirmed by the engineer's test after the operation and excessive drainage of cerebrospinal fluid. BHD replaced the adjustable pressure shunt valve, and the patient recovered. CONCLUSION V-P shunt is a common operation in neurosurgery, and postoperative shunt valve breakdown may lead to poor outcome. We report a rare case of CSDH caused by shunt valve breakdown due to excessive external forces, suggesting that patients after V-P shunt should pay attention to the protection of the shunt valve.

Abstract
BACKGROUND The optimal surgical procedure to reduce the recurrence rate of chronic subdural hematoma (CSDH) after burr-hole surgery remains to be established. This study aimed to investigate the association between artificial cerebrospinal fluid (ACF) use during burr-hole surgery and reoperation rate in patients with CSDH. METHOD In this retrospective cohort study, we used the Japanese Diagnostic Procedure Combination inpatient database. We identified patients aged 40-90 years who were hospitalized for CSDH and had undergone burr-hole surgery within 2 days of admission, between July 1, 2010 and March 31, 2019. We performed a one-to-one propensity score-matched analysis to compare the outcomes between patients with and without ACF irrigation during burr-hole surgery. The primary outcome was reoperation within 1 year of surgery. The secondary outcome was the total hospitalization costs. RESULTS Of the 149,543 patients with CSDH from 1100 hospitals, ACF was used in 32,748 patients (21.9%). Propensity score matching created highly balanced 13,894 matched pairs. In the matched patients, the reoperation rate was significantly lower in the ACF users than that in the non-users group (6.3% vs. 7.0%, P = 0.015), with a risk difference of -0.8% (95% confidence interval, -1.5 to -0.2). There was no significant difference in the total hospitalization costs between the two groups (5079 vs. 5042 US dollars, P = 0.330). CONCLUSIONS ACF use during burr-hole surgery may be associated with lower reoperation rate in patients with CSDH.

Abstract
BACKGROUND Chronic subdural hematomas (CSDHs) are one of the most common neurosurgical conditions. The standard surgical technique includes burr-hole craniostomy, followed by intraoperative irrigation and placement of subdural closed-system drainage. The drainage is generally removed after 48 h, which can be described as fixed-time drainage strategy. According to literature, the recurrence rate is 5-33% with this strategy. In our retrospective study, postoperative hematoma volume was found to significantly increase the risk of recurrence. Based on these results, an exhaustive drainage strategy is conducted to minimize postoperative hematoma volume and achieve a low recurrence rate and good outcomes. METHODS This is a prospective, multicenter, open-label, blinded endpoint randomized controlled trial designed to include 304 participants over the age of 18-90 years presenting with a symptomatic CSDH verified on cranial computed tomography or magnetic resonance imaging. Participants will be randomly allocated to perform exhaustive drainage (treatment group) or fixed-time drainage (control group) after a one-burr hole craniostomy. The primary endpoint will be recurrence indicating a reoperation within 6 months. DISCUSSION This study will validate the effect and safety of exhaustive drainage after one-burr hole craniostomy in reducing recurrence rates and provide critical information to improve CSDH surgical management.

Abstract
BACKGROUND Chronic subdural hematoma (cSDH) is a unique hemorrhagic complication associated with microsurgical clipping. We aimed to investigate the risk factors of subdural hygroma (SDG) formation and its hemorrhagic conversion to cSDH. METHODS We reviewed the medical records of 229 patients who underwent microsurgical clipping for unruptured intracranial aneurysms (UIA) from 2016 to 2019. Risk factors for SDG and cSDH formation were analyzed. RESULTS Male sex, age ≥ 60 years, higher degree of arachnoid dissection, severe brain atrophy, and a large volume of subdural fluid collection (SFC) before discharge were independent risk factors for SDG formation. The risk factors for hemorrhagic conversion from SDG were continuous use or early resumption of antiplatelet drugs (odds ratio (OR): 15.367, 95% CI: 1.172-201.402) and a larger volume of SFC before discharge (OR: 0.932, 95% CI: 0.886-0.980). In the early resumption group, antiplatelet drug was resumed at a mean duration of 7.48 days postoperatively, and hemorrhagic conversion was detected earlier than that in the late resumption or no-use groups (4.09 vs. 7.18 weeks, P = 0.046). Following the receiver operating characteristic analysis, the SFC cutoff volume for hemorrhagic conversion was determined to be 23.55 mL. CONCLUSION These findings can assist clinicians in identifying patients at a high risk of SDG and cSDH formation. Antiplatelet resumption and its timing should be determined with consideration of the risk of cSDH formation as well as individual medical conditions.

Abstract
OBJECTIVE Approximately 10 % of patients with chronic subdural hematoma (CSDH) undergo reoperation after initial surgery. This study aimed to develop a predictive model for the recurrence of unilateral CSDH at initial surgery without hematoma volumetric analysis. METHODS This single-center retrospective cohort study evaluated pre- and postoperative computed tomography (CT) images of patients with unilateral CSDH. The pre- and postoperative midline shift (MLS), residual hematoma thickness, and subdural cavity thickness (SCT) were measured. CT images were classified based on the internal architecture of the hematoma (homogenous, laminar, trabecular, separated, and gradation subtypes). RESULTS Total 231 patients with unilateral CSDH underwent burr hole craniostomy. After receiver operating characteristic analysis, preoperative MLS and postoperative SCT showed better areas under the curve (AUCs) (0.684 and 0.756, respectively). According to the CT classification of preoperative hematomas, the recurrence rate was significantly higher in the separated/gradation group (18/97, 18.6 %) than in the homogenous/laminar/trabecular group (10/134, 7.5 %). Four-point score was derived from the multivariate model using the preoperative MLS, postoperative SCT, and CT classification. The AUC of this model was 0.796, and the recurrence rates at 0-4 points were 1.7 %, 3.2 %, 13.3 %, 25.0 %, and 35.7 %, respectively. CONCLUSION Pre- and postoperative CT findings without hematoma volumetric analysis may predict CSDH recurrence.

Abstract
BACKGROUND In this study, we propose a butterfly needle tap and suction (BTS) technique for recurrent chronic subdural hematoma (CSDH) as an alternative to reoperation with burr hole craniostomy (BHC) and investigate its efficacy and safety. The procedure involves percutaneous puncture through the burr hole created during the previous surgery and subsequent hematoma evacuation using a butterfly needle. METHODS This retrospective study included patients who underwent BTS for CSDH at Ogaki Municipal Hospital between January 2017 and December 2020. The follow-up CT scans were reviewed after several weeks. We evaluated the number of percutaneous punctures required to resolve CSDH during the BTS technique, the volume of the evacuated hematoma, and procedure-related complications. RESULTS Twenty-six patients were enrolled in the study, 21 of whom achieved resolution of the hematoma using punctures with the BTS technique alone (mean, 2.2 ± 1.5). Five patients had a recurrence of hematoma after one or more punctures during the BTS technique, and they underwent reoperation with BHC according to the surgeon's decision or patient requests. Among the 55 punctures, 43.0 ± 16.0 ml of hematoma was evacuated per puncture. The evacuated hematoma volume was 41.9 ± 16.4 ml in the BTS-alone group and 49.4 ± 12.9 ml in the reoperation group, with no significant difference (p = 0.25). Three patients complained of a headache during the puncture procedure, and no other complications, including intracranial hemorrhage or infection, were reported therein. CONCLUSIONS The BTS technique is an effective alternative to reoperation with BHC.

Abstract
Objective This paper aims to analyze the clinical effect and prognosis of neuroendoscopy-assisted surgery for chronic subdural hematoma (CSDH). Methods The clinical data of CSDH patients who underwent surgery between March 2018 and June 2020 in the Department of Neurosurgery of the First Affiliated Hospital of Xiamen University were retrospectively collected and analyzed. Eighty patients with CSDH who met the inclusive criteria were selected. A control group (32 cases treated with burr hole drainage) and an observation group (48 cases treated with neuroendoscopy-assisted surgery) were set according to different operation methods. The hematoma clearance rate, surgery-related indicators, related complications, hematoma recurrence rate and related prognostic indicators of the two groups were compared and analyzed. Result The postoperative hematoma clearance rate of the observation group was 92.59%, which was higher than that of the control group (77.78%) (P<0.05). The operation time of the observation group was longer than that of the control group (P<0.05). The postoperative hospitalization time of the observation group was shorter than that of the control group (P<0.05). The postoperative complication rate of the observation group was lower than that of the control group (P<0.05). The recurrence rate of hematoma in the observation group in the six-month postoperative follow-up was 1.85%, which was lower than that in the control group (P<0.05). The limb motor function and daily living ability score of the observation group were higher than those of the control group, and the Markwalder grading score was lower than that of the control group (P<0.05). Conclusion Neuroendoscopy-assisted treatment which is safe and effective is superior to traditional burr-hole drainage surgery. It can reduce the recurrence rate; thus, it is worth advocating and applying.

Abstract
OBJECTIVE Chronic subdural hematoma (CSDH) is a common neurological condition, often affecting the elderly. Cognitive impairment is frequently observed at presentation. However, the course and longer term aspects of the cognitive status of CSDH patients are unknown. In this study, we aim to explore the cognitive status of CSDH patients after treatment. METHODS An exploratory study in which CSDH patients were assessed 3 months after treatment and compared to healthy controls. A total of 56 CSDH patients (age 72.1 SD ± 10.8 years with 43 [77%] males) and 60 healthy controls were included (age 67.5 ± SD 4.8 with 34 [57%] males). Cognitive testing was performed using the Telephonic Interview of Cognitive Status-modified (TICS-m), a 12-item questionnaire in which a total of 50 points can be obtained on several cognitive domains. RESULTS Median time between treatment and cognitive testing was 93 days (range 76-139). TICS-m scores of CSDH patients were significantly lower than healthy controls, after adjusting for age and sex: mean score 34.6 (95% CI: 33.6-35.9) vs. 39.6 (95% CI: 38.5-40.7), p value < 0.001. More than half (54%) of CSDH patients have cognitive scores at follow-up that correspond with cognitive impairment. CONCLUSION A large number of CSDH patients show significantly worse cognitive status 3 months after treatment compared to healthy controls. This finding underlines the importance of increased awareness for impaired cognition after CSDH. Further research on this topic is warranted.

Abstract
BACKGROUND It is well established that the use of a postoperative drain after chronic subdural hematoma surgery reduces recurrence rates, and it is common to use a postoperative drain for longer than 24 h. It is unclear whether this is superior to a shorter drainage time of less than 24 h. Our aim was to compare a postoperative drainage longer or shorter than 24 h after chronic subdural hematoma evacuation. MATERIALS AND METHODS In this retrospective single centre study, 207 adult patients undergoing chronic subdural hematoma evacuation with a postoperative drainage longer (LDT-group) or shorter (SDT-group) than 24 h were compared regarding recurrence, mortality within 6 months and complications requiring hospital admission within 30 days. Length of hospital stay was also recorded. An active subgaleal drain was used. In addition to the retrospective cohort, we also studied the total volume drained per hour after cSDH surgery in a prospective cohort of 10 patients. RESULTS Recurrence occurred in 12/96 (12.5%) in the LDT-group and in 13/111 (11.7%) patients in the SDT-group (p = 0.15). There was no significant difference between groups regarding recurrence, complications or mortality. The prospective cohort showed that most of the drainage occurred within the first hours after surgery. CONCLUSION Our data show that a postoperative drainage duration of less than 24 h does not lead to an increase in recurrence, complications or mortality compared to a drainage time of more than 24 h. A shorter drainage duration (< 24 h) after cSDH surgery facilitated earlier mobilisation and shorter hospital stay.

Abstract
PURPOSE Middle meningeal artery (MMA) particle embolization is a promising treatment of chronic subdural hematomas (CSDH). The main purpose of this study is to measure MMA proximal caliber and assess the visibility of the two main MMA branches as a surrogate for long-term distal arterial patency following MMA CSDH embolization with trisacryl gelatine microspheres (TAGM). METHODS This is a single-center retrospective study. All patients having undergone MMA TAGM only embolization for CSDH treatment between 15 March 2018 and 6 June 2020 with an interpretable follow-up magnetic resonance imaging (MRI) examination and no confounding factors were included. Patients were compared with controls matched for age, sex and MRI machine. Two independent readers analyzed the MRI images. RESULTS In this study, 30 patients having undergone embolization procedures using TAGM of 36 MMAs were included. The follow-up MRI scans were performed after a mean delay of 14.8 ± 7.1 months (range 4.9-29.4 months). The mean diameter of TAGM embolized MMAs (1 mm; 95% confidence interval, CI 0.9-1.1) was significantly smaller than the mean diameter of paired control MMAs (1.3 mm; 95% CI 1.3-1.4) (p < 0.001). The mean proximal diameter of the embolized MMAs (0.9 mm; 95% CI 0.7-1.1) was significantly smaller than the mean diameter of the contralateral MMAs in the same patients (1.4 mm; 95% CI 1.3-1.6)(p < 0.001). CONCLUSION Long-term follow-up MRI demonstrated a significant impact of TAGM embolization on MMA proximal caliber as well as on the visibility of the two main MMA branches. All comparisons indicated that there was a probable lasting impact of embolization on the patency of distal branches.

Abstract
OBJECTIVE The purpose of this study was to compare the effect of single burr hole (SBH) versus double burr hole (DBH) drainage on the recurrence rate of chronic subdural hematoma (CSDH). METHOD Forty-four patients undergoing burr hole craniostomy (BHC) between July 2022 and December 2022 were enrolled in a randomized clinical trial (RCT) comparing SBH to DBH surgeries. The primary endpoint of this study was the recurrence rate of CSDH. Radiological characteristics such as midline shift, thickness, volume, density, type of hematoma, brain atrophy and so on were secondary endpoints. RESULTS Forty-four patients participated in this study. Twenty-two hematomas underwent SBH craniostomy, and the other 22 had DBH craniostomy. The mean age in the SBH and DBH groups were 68.59 ± 7.94 and 69.54 ± 10.58, respectively. In each group, the proportion of males (SBH=16; DBH=15) was higher than that of females (SBH=6; DBH=7). The mean surgery time in the SBH group was significantly less than in the DBH group (p = 0.001). However, the two groups had no statistically significant difference in the CSDH recurrence rate (p = 0.312). CONCLUSION Our findings showed that SBH craniostomy is equally effective as DBH craniostomy at draining hematomas and does not increase the recurrence rate. Contrarily, the SBH craniostomy had a shorter surgical duration than the DBH craniostomy. As a result, we recommend SBH surgeries for all patients, with emphasis on the elderly and those with severe comorbidities, as well as in situations with few surgical facilities and a high patient admission rate.

World Neurosurg 2023; 171:e120-e125.

Abstract
OBJECTIVE A few reports have demonstrated the efficacy of middle meningeal artery embolization (MMAE) alone for mildly symptomatic chronic subdural hematoma (CSDH); however, the clinical course in the early posttreatment period remains unclear. The purpose of this study was to analyze the short-term outcomes of this technique at our center. METHODS This study was based on a retrospective analysis of a single-center consecutive case series. Patients with mildly symptomatic CSDH treated with MMAE alone between July 2020 and June 2022 were examined. Neurological examinations and head computed tomography scans were performed before treatment and 1, 7, 14, and 28 days after treatment. The clinical course of the patients was analyzed. In particular, symptom improvement within 1 week from treatment or rescue evacuation and the factors associated were evaluated. RESULTS Fifteen patients were included in this study. No procedure-related complications occurred. Partial or complete recovery within the first week from treatment was observed in 10 cases (66.7%), and the symptoms resolved completely in a median of 26 (6.5-33.5) days. Rescue evacuation was needed in 3 cases (20.0%). The hematoma volume and midline shift gradually decreased from baseline, with a significant improvement within the first week (P = 0.030 and 0.0032, respectively). CONCLUSIONS MMAE alone provides relatively early improvement in cases of mildly symptomatic CSDH and may be a potential alternative to surgical evacuation or medical therapy.

Clin Neurol Neurosurg 2023; 227:107640. [PMID: 36870089 DOI: 10.1016/j.clineuro.2023.107640] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Revised: 02/09/2023] [Accepted: 02/18/2023] [Indexed: 03/06/2023]
Abstract
BACKGROUND Some peripheral blood markers have been demonstrated to be correlated with the re-formation of chronic subdural hematoma (CSDH). The aim of this study was to identify the correlation between nutritional/inflammatory peripheral blood markers and CSDH. METHODS 188 CSDH patients and 188 age-matched healthy controls were included in this research. The clinical characteristics and peripheral blood markers associated with nutritional or inflammatory status were obtained and analyzed. Conditional logistic regression analysis was applied to identify the potential CSDH risk factors. All the participants were divided into 3 groups based on the tertiles of change in risk factors. The Cochran-Armitage test and one way ANOVA were applied to identify the association between baseline characteristics and independent risk factors. Moreover, the net reclassification index (NRI) and integrated discrimination index (IDI) were calculated to evaluate the improvement in model performance after adding the independent risk factors in the conventional model. RESULTS The logistic regression analysis demonstrated that the increased albumin (OR, 0.615; 95 %CI,0.489-0.773; P < 0.001) and lymphocyte count (OR, 0.141; 95 %CI,0.025-0.796; P = 0.027) were associated with lower risk of CSDH. Moreover, addition of albumin and lymphocyte to conventional risk factors significantly improved the risk prediction of CSDH(NRI: 46.47 %, P < 0.001; IDI: 30.92 %, P < 0.001; NRI: 22.45 %, P = 0.027; IDI: 1.23 %, P = 0.037, respectively) CONCLUSION: The decreased albumin and lymphocyte levels were correlated with a high risk of chronic subdural hematoma. The nutritional and inflammatory serum markers should be put great attention because these markers may play roles in finding the cause of CSDH and predicting its risk.

Abstract
INTRODUCTION Chronic Subdural Hematoma (CSDH) is a rare but classical evolutive complication of arachnoid cysts (AC). Its management has rarely been evaluated to date. Several approaches have been proposed including conservative and surgical treatments. Endovascular treatment in such CSDH subtype remains poorly reported. CASE PRESENTATION We present here an original case of a 16 years-old-boy suffering from ruptured AC responsible for CSDH successfully treated with embolization. CONCLUSION Endovascular approach may be considered in the treatment of CSDH related to arachnoid cyst rupture.

Abstract
BACKGROUND Chronic subdural hematoma (CSDH) is a common neurosurgical condition with an increasing rate of patient referrals. CSDH referral decision-making is a subjective clinical process, and our aim was to develop a simple scoring system capable of acting as a decision support tool aiding referral triage. METHODS A single tertiary center retrospective case series analysis of all CSDH patient referrals from 2015 to 2020 was conducted. Ten independent variables used in the referral process were analyzed to predict the binary outcome of either accepting or rejecting the CSDH referral. Following feature selection analysis, a multivariable scoring system was developed and evaluated. RESULTS 1500 patient referrals were included. Stepwise multivariable logistic and least absolute shrinkage and selection operator regression identified age <85 years, the presence of headaches, dementia, motor weakness, radiological midline shift, a reasonable premorbid quality of life, and a large sized hematoma to be statistically significant predictors of CSDH referral acceptance (P <0.04). These variables derived a scoring system ranging from -9 to 6 with an optimal cut-off for referral acceptance at any score >1 (P <0.0001). This scoring system demonstrated optimal calibration (brier score loss = 0.0552), with a score >1 predicting referral acceptance with an area under the curve of 0.899 (0.876-0.922), a sensitivity of 83.838% (76.587-91.089), and a specificity of 96.000% (94.080-97.920). CONCLUSIONS Certain patient specific clinical and radiological characteristics can predict the acceptance or rejection of a CSDH referral. Considering the precision of this scoring system, it has the potential for effectively triaging CSDH referrals.

Abstract
Background Chronic subdural hematoma (CSDH) incidence and referral rates to neurosurgery are increasing. Accurate and automated evidence-based referral decision-support tools that can triage referrals are required. Our objective was to explore the feasibility of machine learning (ML) algorithms in predicting the outcome of a CSDH referral made to neurosurgery and to examine their reliability on external validation. Methods Multicenter retrospective case series conducted from 2015 to 2020, analyzing all CSDH patient referrals at two neurosurgical centers in the United Kingdom. 10 independent predictor variables were analyzed to predict the binary outcome of either accepting (for surgical treatment) or rejecting the CSDH referral with the aim of conservative management. 5 ML algorithms were developed and externally tested to determine the most reliable model for deployment. Results 1500 referrals in the internal cohort were analyzed, with 70% being rejected referrals. On a holdout set of 450 patients, the artificial neural network demonstrated an accuracy of 96.222% (94.444-97.778), an area under the receiver operating curve (AUC) of 0.951 (0.927-0.973) and a brier score loss of 0.037 (0.022-0.056). On a 1713 external validation patient cohort, the model demonstrated an AUC of 0.896 (0.878-0.912) and an accuracy of 92.294% (90.952-93.520). This model is publicly deployed: https://medmlanalytics.com/neural-analysis-model/. Conclusion ML models can accurately predict referral outcomes and can potentially be used in clinical practice as CSDH referral decision making support tools. The growing demand in healthcare, combined with increasing digitization of health records raises the opportunity for ML algorithms to be used for decision making in complex clinical scenarios.

Abstract
Embolization of the middle meningeal artery (MMA) is a safe and effective adjunct in the treatment of chronic subdural hematoma. While prior authors describe the use of coils to assist embolization by preventing reflux through eloquent collaterals, we de- scribe the use of coils to further open the MMA, allowing the administration of greater amounts of embolisate for a more robust embolization. The objective of this study was to demonstrate that helical coils can safely open the MMA following the administration of polyvinyl alcohol (PVA) particles. This allows for more embolisate to be administered into the MMA for more effective treatment. A retrospective review was conducted at our institution including intraoperative images and postoperative clinical and radiographic follow up. Failure rates using MMA embolization with PVA and helical coil augmentation were compared to failure rates in the literature of MMA embolization with PVA or ethylene vinyl-alcohol copolymer alone. A total of 8 cases were reviewed in which this technique was implemented. There were no immediate complications after treatment. All patients that underwent helical coil embolization following the administration of PVA had increased amount of embolisate delivered into the MMA. All patients at follow up had resolution of the subdural hematoma on outpatient imaging. Helical coil embolization allows for more embolisate administration into the MMA and provides a technical advantage for patients that fail traditional techniques of embolization. Case series are taking place to further test this hypothesis and identify the ideal patient population that may gain maximal yield from this novel technique.

Abstract
Subdural hematoma is a common entity encountered by the neurosurgeon. The disease has acute, subacute, and chronic forms. Management of the disease changes according to the etiology of the lesion, yet the main goals are, as with most neurosurgical interventions, decompression of neural tissue and restoration of perfusion. Due to various forms and causes of the disease such as trauma, anticoagulant/antiaggregant use, arterial rupture, oncologic hemorrhages, intracranial hypotension, and idiopathic hemorrhages, several approaches for management have been documented in the literature. Herewith, we present various up-to-date management options for the disease.

Abstract
Most historical articles have named Johann Jacob Wepfer as the first author to describe a case of chronic subdural hematoma (CSDH). However, the question arises whether these cases truly describe CSDH. Two other names that appear in literature as the first authors to describe a case of CSDH are Thomas Willis and Giovanni Battista Morgagni. In our attempt to find the first description of a CSDH, we studied the original cases described by Willis, Wepfer, and Morgagni. The cases described by Willis and Wepfer cannot be interpreted as cases of CSDH. Willis's university scholar is more likely to have experienced venous infarction with an underlying septic thrombosis than a CSDH. Wepfer's cases seem to represent an intraparenchymal hemorrhage from the rupture of a branch or branches of the internal carotid artery, a subarachnoid hemorrhage complicated with hydrocephalus, and a hydrocephalus in tuberculous meningitis. Morgagni's case described in Letter III, Article 20 in the Sedibus in 1761 seems to be the first accurate historical description of a CSDH, and we believe it should be cited as such. With these early cases of alleged CSDH, we emphasize the importance of misquotation and blind copying of references, which are important citation errors.

Abstract
BACKGROUND Chronic subdural hematoma (CSDH) is one of the most common neurosurgical conditions. Here, we studied differences in demographics, treatment, and outcome for CSDH patients in low-income (Ethiopia) and high-income (Norway) countries and assessed potential outcome determinants. METHODS We included patients from Addis Ababa University Hospitals (AAUH) and Haukeland University Hospital (HUH) who had surgery for CSDH (2013-2017). Patients were included prospectively in Ethiopia and retrospectively in Norway. RESULTS We enrolled 314 patients from AAUH and 284 patients from HUH, with a median age of 60 and 75 years, respectively. Trauma history was more common in AAUH (72%) than in HUH patients (64.1%). More patients at HUH (45.1%) used anticoagulants/antiplatelets than at AAUH (3.2%). Comorbidities were more frequent in HUH (77.5%) than in AAUH patients (30.3%). Burr hole craniostomy under local anesthesia and postoperative drainage was the standard treatment in both countries. Postoperative CT scanning was more common at HUH (99.3%) than at AAUH (5.2%). Reoperations were more frequent at HUH (10.9%) than at AAUH (6.1%), and in both countries, mostly due to hematoma recurrence. Medical complications were more common at HUH (6.7%) than at AAUH (1.3%). The 1-year mortality rate at HUH was 7% and at AAUH 3.5%. At the end of follow-up (> 3 years), the Glasgow Outcome Scale Extended (GOSE) score was 8 in 82.9% of AAUH and 46.8% of HUH patients. CONCLUSION The surgical treatment was similar at AAUH and HUH. The poorer outcome in Norway could largely be explained by age, comorbidity, medication, and complication rates.

Abstract
Chronic subdural hematoma (cSDH) is defined as a subdural collection of blood on CT imaging that tends to persist and gradually increase in volume over time, with components that are hypodense or isodense compared to the brain. There are no proven guidelines for the management of patients with cSDH. Surgical approaches included burr hole, twist drill hole, and craniotomy-based evacuations. Outcomes after surgical removal is generally favorable, but cSDH tends to recur after the initial evacuation.Middle meningeal artery (MMA) embolization has been gaining increasing popularity among the treatments of cSDH. This is largely due to a growing population of patients with cSDH who are refractory to other treatments or in patients who present with multiple comorbidities or who are taking antiplatelet and anticoagulant medications. The goal of middle meningeal artery (MMA) embolization is to devascularize subdural membranes associated with SDH so that the balance between continued leakage and reabsorption is shifted toward reabsorption.We discuss our clinical and technical approach to cSDH treated with perioperative embolization of the MMA.

Abstract
Recently, a relationship between traumatic subdural hygroma (SDG) and chronic subdural hematoma (CSDH) has been proposed. However, the role of traumatic SDG in development of CSDH has not been well characterized. This systematic review aimed to estimate the rate of evolution of traumatic SDG to CSDH, and to identify risk factors associated with traumatic SDG evolution to CSDH. We searched MEDLINE, EMBASE, and Cochrane Library databases from inception to May 26, 2021, using the combination of the terms "subdural hygroma" and "chronic subdural hematoma." Using a random-effects model, we calculated a pooled estimate of rate of evolution of traumatic SDG to CSDH. In addition, we conducted a systematic review of studies of risk factors for traumatic SDG evolution to CSDH. Nineteen studies with 1,335 patients met the inclusion criteria for meta-analysis. The pooled estimate of evolution rate was 25.0 % (95 % CI, 19.3 %-30.7 %; I2 = 85.6 %), with significant heterogeneity among studies (P < 0.01). Age ≥ 60 years was associated independently with traumatic SDG evolution to CSDH, after adjustment for study design using multivariate meta-regression. Risk factors associated with evolution of traumatic SDG to CSDH were radiological characteristics such as thicker SDG and higher SDG CT value. The rate of traumatic SDGs evolution to CSDH is approximately 25 %. Patients aged 60 or older with traumatic SDGs are at increased risk of CSDH development. Thicker SDG and higher SDG CT value, are commonly reported risk factors for traumatic SDG evolution to CSDH. However, higher quality studies are needed.

Abstract
Chronic subdural hematomas (CSDHs) are a common neurosurgical disease for which middle meningeal artery (MMA) embolization is emerging as an attractive and efficacious endovascular treatment modality. We present the first known case of a Streptococcus intermedius epidural abscess that resulted following MMA embolization for a left-sided CSDH that required evacuation and washout through a craniotomy. Intracranial infections can be a potentially devastating complication from MMA embolization in this patient population.
