Abstract
BACKGROUND This study aims to investigate the benefits of employing a Physical Lifelike Brain (PLB) simulator for training medical students in performing craniotomy for glioblastoma removal and decompressive craniectomy. METHODS This prospective study included 30 medical clerks (fifth and sixth years in medical school) at a medical university. Before participating in the innovative lesson, all students had completed a standard gross anatomy course as part of their curriculum. The innovative lesson involved PLB Simulator training, after which participants completed the Learning Satisfaction/Confidence Perception Questionnaire and some received qualitative interviews. RESULTS The average score of students' overall satisfaction with the innovative lesson was 4.71 out of a maximum of 5 (SD = 0.34). After the lesson, students' confidence perception level improved significantly (t = 9.38, p < 0.001, effect size = 1.48), and the average score improved from 2,15 (SD = 1.02) to 3.59 (SD = 0.93). 60% of the students thought that the innovative lesson extremely helped them understand the knowledge of surgical neuroanatomy more, 70% believed it extremely helped them improve their skills in burr hole, and 63% thought it was extremely helpful in improving the patient complications of craniotomy with the removal of glioblastoma and decompressive craniectomy after completing the gross anatomy course. CONCLUSION This innovative lesson with the PLB simulator successfully improved students' craniotomy knowledge and skills.

Abstract
BACKGROUND Chronic subdural hematoma (CSDH) is a neurosurgical pathology of an aged populace. Pathogenetic risk factors include traumatic brain injury, prolonged use of antiplatelet drugs, hypertension, and some inflammatory processes. The incidence increases as patients age. Burr-hole evacuation is the most common approach in management of symptomatic cases. We compared evacuation of chronic subdural hematomas with general or local anesthesia (GA and LA, respectively) and evaluated the safety, economic benefits, effects of comorbidity, benefits, and shortcomings of both techniques. METHODS We conducted a retrospective study of 67 consecutive patients who had 74 procedures for CSDH in a single neurosurgical center, the Regional Clinic, Centre of Neurosurgery and Neurology, over a 3-year period. They were grouped into the GA group (n = 44) and LA group (n = 23). Mean duration of procedure, length of hospital stay, complications, and preoperative and postoperative neurologic statuses were compared. The distribution of nominal variables between groups was compared using the Fisher exact test. The average duration of operation and length of hospital stay were compared using the Mann-Whitney U-test due to violation of the normality assumption. RESULTS LA proved to be as effective as GA in CSDH evacuation. Seventy-four surgical procedures were performed on 67 patients due to recurrence in less than 30 days in 7 patients. Fifteen patients had tension pneumocephalus managed with fluid therapy to full recovery. LA was economical and required shorter hospital stays and surgical time. CONCLUSIONS In our studies, LA proved to be noninferior to GA, time conserving, and less prone to some of the adverse effects of GA on elderly patients with comorbidity, although some patients who are hyperactive or contraindicated to LA will require GA.

Abstract
INTRODUCTION Chronic subdural haematoma (CSDH) is one of the most common neurosurgical emergencies, especially in the elderly population. Surgery is the mainstay of treatment for CSDH. Some studies have suggested that some specific surgical strategies can have potential benefits for patients with CSDH; however, the best surgical method is still controversial. For a better understanding of surgical treatment for these patients, it is necessary to conduct a network meta-analysis to comprehensively compare the effects of medical treatment and different surgical methods. METHODS AND ANALYSIS This protocol has been reported following the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. Related studies published up to April 2023 will be searched in the following databases: PubMed, Embase, Scopus, Web of Science, the Cochrane Library, China National Knowledge Infrastructure, VIP and Wanfang. Randomised controlled trials and non-randomised prospective studies comparing at least two different interventions for patients with CSDH will be included. Quality assessment will be conducted using Cochrane Collaboration's tool or the Newcastle-Ottawa Scale based on study design. The primary outcome will be the recurrence rates, and the secondary outcome will be the functional outcome at the end of follow-up. Pairwise and network meta-analyses will be conducted using STATA V.14 (StataCorp, College Station, Texas, USA). Mean ranks and the surface under the cumulative ranking curve will be used to evaluate each intervention. Statistical inconsistency assessment, subgroup analysis, sensitivity analysis and publication bias assessment will be performed. ETHICS AND DISSEMINATION Ethics approval is not necessary because this study will be based on publications. The results of this study will be published in a peer-reviewed journal.

Abstract
BACKGROUND The aim of our study was to investigate the effect of the burr hole width on the postoperative chronic subdural hematoma (CSH) thickness and midline shift radiologically. METHODS The medical records of 92 patients who had undergone surgery after a diagnosis of CSH between April 1, 2015 and July 1, 2021 were reviewed retrospectively. Preoperative and postoperative computed tomography (CT) scans were reviewed, and the thickness of the hematoma and midline shift and the diameters of 2 burr holes opened were measured and recorded. The correlation between the burr hole diameter width and CSH thickness on postoperative CT scans and the improvement in midline shift were investigated statistically. RESULTS When the CT scans performed on the first postoperative day and first postoperative month were examined, we found that the preoperative hematoma thickness and midline shift were significantly reduced postoperatively (P < 0.001). A positive significant correlation was found between the improvement in the midline shift, posterior burr hole diameter, and anteroposterior burr hole arithmetic mean (P < 0.001 and P = 0.029, respectively). CONCLUSIONS Having examined the current surgical techniques in the treatment of CSH, we found that an increase in the burr hole craniostomy width, especially the posterior burr hole craniostomy width, contributed to the improvement in the midline shift.

Abstract
Abstract
Background Chronic subdural hematoma (CSDH) is not a totally benign disease in the elderly patients, especially those aged 70 years and above. Hence, the surgical treatment of CSDH in aged patients needs to be as minimally disruptive as possible.
Methods An annotated description of the surgical technique of single frontal burr-hole craniostomy performed under local anesthesia and without closed tube drainage for evacuating CSDH in the septuagenarians and older adults is given. We also review the outcome of the procedure on a prospective consecutive cohort of patients in our service
Results Thirty patients, 25 males, aged 70 years and above successfully underwent this surgical procedure. Their mean age was 76.5 years (standard deviation, 4.3). The CSDH was bilateral in 30% (9/30), and more left sided in the rest, the unilateral cases, and was of mixed density radiologically, in most cases (73%, 22/30). Clinical presentation was mainly gait impairment, cognitive decline, and headache, and 57% (17/30) presented with coma or stupor as assessed by the Markwalder grading scale.The surgery was successfully executed in all, median duration 45.0 minutes (interquartile range 37.3–60.0), and solely under local anesthesia in 77% (23/30) or with momentary short-acting sedation in the rest. The outcome was very good in 90.0% (27/30) using the modified Rankin Scale (mRS) including two-third (20/30) completely asymptomatic (mRS 0) and 7/30 with only slight symptoms/disability, mRS ≤ 2. Three patients died perioperatively, all presenting in coma.
Conclusion This surgical technique appears very effectual for CSDH, is executed at a comparatively low cost, and, being much less disruptive than other traditional methods, may be a more homeostatic operative treatment in geriatric patients at least.

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
Chronic subdural hematoma (cSDH) is one of the most common neurosurgical entities, especially in the elderly population. Diagnosis is usually established via a head computed tomography, while an increasing number of studies are investigating biomarkers to predict the natural history of cSDH, including progression and recurrence. Surgical evacuation remains the mainstay of treatment in the overwhelming majority of cases. Nevertheless, many controversies are associated with the nuances of surgical treatment. We performed a systematic review of the literature between 2010 and 2022, aiming to identify and address the issues in cSDH surgical management where consensus is lacking. The results show ambiguous data in regard to indication, the timing and type of surgery, the duration of drainage, concomitant membranectomy and the need for embolization of the middle meningeal artery. Other aspects of surgical treatment-such as the use of drainage and its location and number of burr holes-seem to have been adequately clarified: the drainage of hematoma is strongly recommended and the outcome is considered as independent of drainage location or the number of burr holes.

Abstract
Background Preoperative identification of clinical, radiographic, and surgery-specific factors associated with nonacute subdural hematomas (SDHs) may enable clinicians to optimize the efficacy of the initial surgical intervention, improve outcomes, and decrease rates of surgical recurrence. Methods The authors identified patients aged ≥65 years who underwent surgical treatment of chronic, subacute, or mixed-density SDH at a level-1 trauma hospital over a ten-year period (2010-2019). Pre-and postoperative clinical, radiographic, and surgery-specific data were collected. Predictors of surgical recurrence as well as morbidity, mortality, and discharge disposition were analyzed. Results There were 268 nonacute SDHs treated surgically; 46 were chronic, 19 were subacute, and 203 were mixed density. Of these, 179 were treated with burr hole(s), 62 with miniature craniotomy, and 27 via a large craniotomy and removal of subdural membranes. Statin use was protective (OR 0.22; 95% CI 0.08, 0.60) against recurrence requiring reoperation. Preoperative use of antithrombotic agents was not significantly associated with increased recurrence requiring reoperation. Smaller preoperative hematoma thickness was associated with significantly lower mortality risk, whereas mixed-density hematomas, patient age, change in thickness after surgery, density, and presence of cisternal effacement were significantly associated with discharge disposition. Hematoma type was also associated with hospital and intensive care length of stay. Conclusions Our experience suggests that, in elderly patients, premorbid statin usage is associated with lower recurrence rates and preoperative antithrombotic use does not affect recurrence when appropriately reversed before surgery. Patient age, preoperative thickness, and hematoma type contribute to postoperative outcomes such as discharge disposition and length of stay.

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
Non-acute subdural hematomas (naSDH) may recur after surgical treatment. A second operation affects the quality of life and functional outcome of the patients, and lengthens hospital stay. We aim to identify the predictors of reoperation as the healthcare system in the US is moving towards patient-centered care. This retrospective study included patients treated surgically with burr-holes or mini-craniotomy for non-acute subdural hematoma between February 2006-June 2018. Univariate and multiple logistic regression models were performed. 23 (12.0%) patients had reoperation. Controlling for all the factors, postoperative acute blood in the operative bed was the strongest predictor of recurrence of naSDH (OR = 37.93, 95% CI: 5.35-268.87, p < 0.001). Those undergoing a mini-craniotomy were over six times as likely to experience a recurrent SDH compared to those operated on via burr holes (OR = 6.34, 95% CI: 1.21-33.08, p = 0.029). Finally, patients with a past medical history of thrombocytopenia were nearly six times as likely to experience a recurrence of SDH (OR = 5.80, 95% CI: 1.20-28.10, p = 0.029). Postoperative hematoma thickness showed a trend toward significance such that thicker hematomas were associated with an increased likelihood of experiencing a recurrent SDH. In conclusion, we found that operative technique, thrombocytopenia and the presence of postoperative hemorrhage are significant predictors for reoperation. Given the current interest in endovascular embolization for SDH, understanding these risk factors may aid in determining indications for such adjunctive treatment.

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
OBJECTIVE Recurrent subdural hematoma (SDH) is commonly encountered in clinical practice. Multiple surgical techniques have been reported for management of recurrent SDH with variable success and complication rates. We report an alternative technique to halt SDH reaccumulation in elderly patients with multiple recurrences despite multiple surgical evacuations via rescue craniectomy and subsequent cranioplasty. METHODS We retrospectively identified all symptomatic recurrent SDHs in elderly patients (≥60 years old) who were surgically managed with rescue craniectomy with subsequent cranioplasty from November 2004 to January 2018. Patients' demographics and radiologic and surgical variables were recorded and analyzed. RESULTS Of 287 patients who received surgical treatment for SDH, 19 patients (6.6%) underwent SDH evacuation with rescue craniectomy and subsequent cranioplasty were included in the study. The median age of the cohort was 73 years (interquartile range: 62-78 years), with 13 men and 6 women. Trauma was the cause of SDH in most cases. Five patients had acute SDH, 4 patients had subacute SDH, and 10 patients had chronic SDH. Fourteen patients had only 1 recurrence of SDH requiring surgical re-evacuation, and 5 had 2 recurrences. Median interval between craniectomy and cranioplasty was 64.5 days (interquartile range: 15-123.3 days). Four complications were encountered. After cranioplasty, 15 patients had no further hemorrhage or recurrence and 4 patients had stable subdural collection during an average follow-up of 38.2 ± 46.9 months. CONCLUSIONS Rescue craniectomy followed by cranioplasty is a safe and effective salvage technique for the management of symptomatic recurrent SDH in elderly patients.

Abstract
Objective Chronic subdural hematoma drainage is one of the most common procedures performed in neurosurgical practice. Not only burr hole drainage but also small craniotomy (diameter 3–5 cm) is frequently used neurosurgical treatment of chronic subdural hematomas. We assessed to compare the postoperative recurrence rates between burr hole drainage versus small craniotomy with closed-system drainage for chronic subdural hematomas. Methods From January 2016 to December 2018, 75 patients who were treated with burr hole drainage and small craniotomy with closed system drainage for the symptomatic chronic subdural hematoma were enrolled. Pre and postoperative computed tomography (CT) were used for radiologic evaluation. The choice of procedure was decided by preoperative CT images. Results 60 patients out of 75 patients underwent burr hole drainage, whereas 15 patients underwent small craniotomy. The overall postoperative recurrence rate was 16%. The recurrence occurred in 8 patients out of 60 patients in burr hole drainage group (13.3%) and 7 patients out of 15 patients in small craniotomy group (46.7%). The number of days of hospitalization was 10.3 days in burr hole drainage group and 15.7 days in small craniotomy group. Conclusion Burr hole drainage would be sufficient to evacuate chronic subdural hematoma with lower recurrence rate, but small craniotomy was also needed in some cases such as hematoma has solid portion or multiple septum.

Abstract
The aim of this study was to determine the subdural haematoma recurrence rate in patients with symptomatic chronic subdural haematomas (CSDH) treated with either burr hole trephination (BHT) or minicraniotomy (MC) and to determine whether a statistically significant difference exists between the two techniques. A retrospective analysis of all consecutive patients with symptomatic CSDH treated with BHT or MC at the John Hunter Hospital Neurosurgery Department between July 2004 and July 2016 was performed. After inclusion/exclusion criteria were applied, 368 patients with 439 CSDHs were eligible. Baseline demographic data was recorded for all patients. Statistical analysis was performed assessing haematoma recurrence as the primary outcome and mortality as a secondary outcome. Three hundred and sixty eight patients were included in the study, with 225 being treated with MC and 143 with BHT. Baseline demographic data was similar between the two groups. The recurrence rate for patients treated with BHT was 0.13 (95% CI 0.08-0.18), versus 0.18 (95% CI 0.13-0.23) in the MC group. This difference was not statistically significant. Similarly, there was no statistically significant difference in mortality rates between the two groups. The mortality rate in the BHT group was 0.09 (95% CI 0.05-0.14) versus 0.09 (95% CI 0.05-0.13) in the MC group. In our series there was no difference in recurrence rates or mortality rates between the two groups, suggesting MC is an effective alternative to BHT in the management of symptomatic CSDH.

Abstract
OBJECTIVE To determine the effectiveness of basal membranotomy performed to ensure cerebral expansion in patients operated for chronic subdural hematoma. METHODS Patients who were operated for unilateral chronic subdural hematoma and underwent basal membranotomy in addition to hematoma drainage were included in the first phase of the study. After the superficial membranous structures were excised, the maximum perpendicular distance between the internal tabula and the cerebral surface was measured after subdural hematoma evacuation. Subsequently, basal membranotomy was performed, the maximum perpendicular distance between the internal tabula and the cerebral surface was measured again, and the improvement in cerebral expansion was statistically calculated. The improvement of cerebral expansion in the patients who had undergone double burr hole drainage was statistically calculated in the second stage of the study. RESULTS The cerebral expansion after the basal membrane excision was 41.1% in those with a 1.5- to 2-cm hematoma, 43.1% in those with a 2.1- to 3-cm hematoma, 43.5% in those with a 3.1- to 4-cm hematoma, and 45.4% in those with a hematoma thicker than 4 cm on average. No recurrence was seen during the 6-month follow-up in any patient. Double burr hole drainage revealed similar values for cerebral expansion increase with a mean value of 10%. The burr hole drainage was repeated because of recurrence in 5 patients during the 2-month follow-up. CONCLUSIONS The mini craniotomy-basal membranotomy technique provided statistically significantly better cerebral expansion in patients with chronic subdural hematoma when compared with the double burr hole drainage technique.

Abstract
A miniature, 10 mm aperture histotripsy transducer with an f-number of 0.7 was fabricated using an elliptically shaped aluminum lens, which was epoxy-bonded to an air-backed 5.0 MHz, PTZ-5A, 1-3 dice-and-fill piezoelectric composite, and the lens coupled to water using a quarter-wavelength matching layer of Parylene-C. A Krimholtz-Leedom-Matthaei model of the device and curved lens was developed. The epoxy layer resulted in an increased power output at 6.8 MHz compared to the 5 MHz composite design. Cavitation was observed in water by driving the composite with a 173 V single-cycle, unipolar 6.8 MHz pulse at a pulse repetition frequency of 50 Hz, and a bubble cloud 264 long by 124 wide was measured. A coregistered imaging and ablation device was also fabricated and characterized. The coregistered device was modified to include a mm square hole through the center, allowing access for a high-frequency imaging array, and both imaging and ablation are demonstrated in cerebral tissue with this device. Radial -3 dB beam widths were measured as 0.145 and 0.116 mm, and axial -3 dB depths of field were 0.698 and 0.752 mm for the noncoregistered and coregistered transducers, respectively. Total material cost for the transducer and pulser board is below $200 USD.

Abstract
OBJECTIVEChronic subdural hematoma (CSDH) is commonly encountered in neurosurgical practice. However, surgical evacuation remains complicated by a high rate of reoperation. The optimal surgical approach to reduce the reoperation rate has not been determined. In the current study, the authors evaluated the prognostic value of clinical and radiographic factors to predict reoperation in the context of CSDH.METHODSA retrospective review of 325 CSDH patients admitted to an academic medical center in the United States, between 2006 and 2016, was performed. Clinical and radiographic factors predictive of the need for CSDH reoperation were identified on univariable and multivariable analyses.RESULTSUnivariable analysis showed that warfarin use, clopidogrel use, mixed hypo- and isointensity on T1-weighted MRI, greater preoperative midline shift, larger hematoma/fluid residual on first postoperative day CT, lesser decrease in hematoma size after surgery, use of monitored anesthesia care (MAC), and lack of intraoperative irrigation correlated with a significantly higher rate of reoperation. Multivariable analysis, however, showed that only the presence of loculation, clopidogrel or warfarin use, and percent of hematoma change after surgery significantly predicted the need for reoperation. Our results showed that 0% (no reduction), 50%, and 100% hematoma maximum thickness change (complete resolution of hematoma after surgery) were associated with a 41%, 6%, and < 1% rate of reoperation, respectively. The use of drains, either large diameter or small caliber, did not have any effect on the likelihood of reoperation.CONCLUSIONSAmong many factors, clopidogrel or warfarin use, hematoma loculation on preoperative CT, and the amount of hematoma evacuation on the first postoperative CT were the strongest predictors of reoperation.

Abstract
INTRODUCTION Chronic subdural hematoma (cSDH) is a common condition that causes significant morbidity and mortality. In rural sub-Saharan Africa, there are very few neurosurgeons. Yet, cSDH is treatable by relatively simple surgical intervention with potential for rapid clinical improvement. METHODS We conducted a retrospective chart review of all patients with cSDH who underwent burr-hole trephination at Tenwek Hospital, Kenya, between July 2014 and July 2016. We extracted and compared the clinical presentation, risk factors, operative details, and outcomes. RESULTS A total of 119 patients were identified with a mean age of 61.3 years. The majority were men (80%). The main predisposing factors were trauma (54.6%) and alcohol intake (34.4%). Patients were generally managed with two burr-holes, irrigation, and a subdural drain, remaining for a median of 2 days. Operations were assisted by general surgery residents under direct supervision of senior residents (46), general surgeons (65), and neurosurgeons (8). Complications included recurrence (5.2%), subdural empyema (2.5%), postoperative seizures (3.4%), and mortality (6.7%). Improvement of symptoms was noted in 91% of all patients. CONCLUSION Operative management of cSDH can be safely performed in rural facilities by general surgeons familiar with the procedure and with the institutional resources. The majority of patients had satisfactory outcomes.

Abstract
PURPOSE OF REVIEW Management of patients with subdural hematomas starts with Emergency Neurological Life Support guidelines. Patients with acute or chronic subdural hematomas (SDHs) associated with rapidly deteriorating neurologic exam, unilaterally or bilaterally dilated nonreactive pupils, and extensor posturing are considered imminently surgical; likewise, SDHs more than 10 mm in size or those associated with more than 5-mm midline shift are deemed operative. RECENT FINDINGS While twist drill craniostomy and placement of subdural evacuating vport system (SEPS) are quick, bedside procedures completed under local anesthesia and appropriate for patients with chronic SDH or patients that cannot tolerate anesthesia, these techniques are not optimal for patients with acute SDH or chronic SDH with septations. Burr hole SDH evacuation under conscious sedation or general anesthesia is an analogous technique; however, it requires basic surgical equipment and operating room staff, with a focus on a closed system with burr hole followed by rapid drain placement to avoid introduction of air into the subdural space, or multiple burr holes with extensive irrigation to reduce pneumocephalus and continue SDH evacuation via drain for several days. Acute SDH associated with significant mass effect and cerebral edema requires aggressive decompression via craniotomy with clot evacuation and frequently a craniectomy. Chronic SDHs that fail conservative management and progress clinically or radiographically are addressed with craniotomy with or without membranectomy. Surgical SDH management is variable depending on its characteristics and etiology, patient's functional status, comorbidities, goals of care, institutional preferences, and availability of specialized surgical equipment and adjunct therapies. Rapid access to surgical suites and trained staff to address surgical hemorrhages in a timely manner, with appropriate post-operative care by a specialized team including neurosurgeons and neurointensivists, is of paramount importance for successful patient outcomes. Here, we review various aspects of surgical SDH management.

Abstract
BACKGROUND Chronic subdural hematoma (CSDH) is one of the most common neurosurgical conditions. It is mostly a disease of elderly population with very little data about the young patients. There is also the debate regarding treatment strategies. We decided to determine the overall efficacy of the single burr-hole craniostomy (SBHC) for unilateral CSDH in young adults <40 years. SUBJECTS AND METHODS We performed a retrospective study of young patients undergoing SBHC for unilateral CSDH between January 2013 and June 2016 at our institution. Medical records were assessed based on patient characteristics in the form of sex of the patient, etiology, presenting symptoms, comorbidities, and signs including Glasgow Coma Scale, computed tomography (CT) brain findings (site and thickness of SDH with midline shift), and intraoperative presence of chronic/subacute component. RESULTS Mean age of the patient was 33.69 years (range 18-40 years), mean thickness of SDH was 15.47 mm, and mean midline shift was 11.26 mm. 61.54% patients were male, trauma being the most common etiology (92.31%) with most common presenting complaint being headache (90.38% patients). 69.23% patients presented within 1 day of onset of symptoms. On CT scan, most of the patients were having SDH thickness between 11 and 20 mm (67.31%) with midline shift of 6-10 mm (53.85%). Right-sided SDH was present in 53.85%. Intraoperatively, 63.46% patients had subacute SDH whereas 34.61% had chronic component. There were total 2 recurrences (3.85%). CONCLUSIONS Young adults who present with unilateral CSDH usually have a history of trauma. They have shorter duration of symptoms and present mainly with the features of raised intracranial pressure such as headache and vomiting. SBHC with irrigation and drainage has excellent result for unilateral CSDH in young adults compared to other methods of drainage and should be considered treatment of choice unless contraindicated.

Abstract
OBJECTIVE Initial management strategies of chronic subdural hematoma (cSDH) are controversial and range from bedside twist-drill or burr-hole drainage to craniotomy with membranectomy (CWM). We aim to 1) perform a meta-analysis of the available data on the outcomes of CWM for treatment of cSDH in published English-language literature and 2) evaluate collective outcomes of CWM with respect to morbidity, mortality, and recurrence rates. METHODS A search of English-language literature performed in PubMed, Ovid, and Cochrane databases using key words ("subdural hematoma" or "chronic subdural hematoma") and ("membrane" or "membranectomy") from inception to December 2016 was conducted. Studies reporting outcomes of CWM in cSDH were included. Mortality, morbidity, follow-up duration, and recurrence rate data were extracted and analyzed. Pooled estimates and confidence intervals (CIs) were calculated for all outcomes using a random-effects model. RESULTS Of 301 articles found, 17 articles containing 5369 patients met our eligibility criteria. Mean follow-up duration ranged from 1-30.8 months. Collective mean mortality and morbidity rates were 3.7% and 6.9%, respectively (95% CI 2-5.4% and 2.1-11.6%; P < 0.001 and P = 0.004). The collective mean recurrence rate was 7.6% (95% CI: 5%-10.2%; P < 0.001). CONCLUSIONS Clinical data on outcomes of CWM in cSDH are limited to single institutional analyses, with considerable variation in recurrence rates and follow-up time. The rates we reported are comparable with the 5% mortality and 3%-12% morbidity rates and lower than the 10%-21% recurrence rate in the literature for burr holes or craniotomy without membranectomy. This meta-analysis provides an in-depth analysis of available data and reviews reported outcomes.

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
BACKGROUND The use of anticoagulants and older age are the main risk factors for chronic subdural hematoma (CSDH). Because the age of the population and use of anticoagulants are increasing, a growing number of CSDH cases is expected. To address this issue, we analyzed the impact of anticoagulants on postsurgical outcome in patients in the intensive care unit (ICU). METHODS Demographic data, coagulation parameters, surgical details, radiologic appearance of hematoma, Glasgow Coma Scale (GCS) score on admission, and Glasgow Outcome Scale (GOS) score on discharge were retrieved and retrospectively analyzed in 98 patients with CSDH treated in the neurosurgical ICU using correlation coefficient tests and multivariate analysis test. RESULTS Overall outcome was good (GOS score 4 and 5) in 55.1% of patients. Overall mortality was 9.1%. There was a correlation between GCS score on admission and GOS score. There was no correlation between hematoma thickness/radiologic appearance and impaired coagulation. Disturbance in thrombocyte function (usually resulting from aspirin intake) correlated with improved outcome, whereas warfarin-related coagulopathy correlated with poor recovery. Nevertheless, patients with thrombocytopathy presented with better initial GCS scores. Neither hematoma size nor recurrence rate affected the outcome. CONCLUSIONS The size of CSDH was not associated with poor outcome and is not necessarily determined by the use of anticoagulants. Coagulopathy does not rule out a good outcome, but the impact of anticoagulation on treatment results in CSDH varies between the main groups of drugs (warfarin vs. antiplatelet drugs). Patients in good neurologic condition on ICU admission have better chances of recovery.

Abstract
UNLABELLED OBJECTIVE : To describe a surgical technique and to report using a retrospective study the efficacy of peritoneal shunts for the treatment of recurrent/chronic subdural hematoma (CSDH). We describe the considerations, complications, and outcomes related to this technique. METHODS : In a retrospective cohort study, 125 charts with a diagnosis of subacute/chronic subdural hematoma were assigned for evaluation. Of the charts reviewed, 18 charts were found from subjects with a diagnosis of recurrent sub-acute or chronic subdural hematoma. All patients had undergone initial surgical treatment of their condition followed by peritoneal shunt placement to help alleviate intracranial pressure. Factors including the age, size of subdural hematoma, number of previous events, BMI, complications, survival, and clinical course were analyzed. RESULTS : After subdural peritoneal shunt placement all patients had full neurological recovery with no complaints of headaches, lethargy, weakness, confusion or seizures. None of the cases had new subdural hematoma episodes after placement for a minimum of a two-year period (mean 26.1 months) (range 24.3-48.6 months). No postoperative complications were reported. The rates of postoperative hemorrhage, infection, distal catheter revision, and perioperative seizures was found to be zero percent. Shunt drainage was successful in all cases, draining 85% of the blood in the first 48 hours. There was no significant relationship between complications and the use of anticoagulants four weeks after surgery. CONCLUSIONS Peritoneal shunts, though rarely used, are a viable option in the treatment of sub-acute/chronic subdural hematomas. When pursuing this treatment, this technique is recommended to mitigate the risks of repeat surgical intervention and lessen perioperative time in high-risk patients.

Abstract
Chronic subdural hematoma (CSDH) is one of the most common neurosurgical conditions. There is lack of uniformity in the treatment of CSDH amongst surgeons in terms of various treatment strategies. Clinical presentation may vary from no symptoms to unconsciousness. CSDH is usually diagnosed by contrast-enhanced computed tomography scan. Magnetic resonance imaging (MRI) scan is more sensitive in the diagnosis of bilateral isodense CSDH, multiple loculations, intrahematoma membranes, fresh bleeding, hemolysis, and the size of capsule. Contrast-enhanced CT or MRI could detect associated primary or metastatic dural diseases. Although definite history of trauma could be obtained in a majority of cases, some cases may be secondary to coagulation defect, intracranial hypotension, use of anticoagulants and antiplatelet drugs, etc., Recurrent bleeding, increased exudates from outer membrane, and cerebrospinal fluid entrapment have been implicated in the enlargement of CSDH. Burr-hole evacuation is the treatment of choice for an uncomplicated CSDH. Most of the recent trials favor the use of drain to reduce recurrence rate. Craniotomy and twist drill craniostomy also play a role in the management. Dural biopsy should be taken, especially in recurrence and thick outer membrane. Nonsurgical management is reserved for asymptomatic or high operative risk patients. The steroids and angiotensin converting enzyme inhibitors may also play a role in the management. Single management strategy is not appropriate for all the cases of CSDH. Better understanding of the nature of the pathology, rational selection of an ideal treatment strategy for an individual patient, and identification of the merits and limitations of different surgical techniques could help in improving the prognosis.

Abstract
Chronic subdural hematoma (CSDH) is a collection of old blood and its breakdown products between the surface of the brain parenchyma and the outermost layer called the dura. The most common treatment option for primary CSDH is burr-hole trephination; however, the treatment method for recurrent CSDH is still widely debated. An arachnoid cyst (AC) is a sac filled with cerebrospinal fluid located between the brain or spinal cord and the arachnoid membrane, which is one of the three meninges covering the brain or spinal cord. Although it is rare, the cyst is associated with CSDH in juveniles, and the recurrence rate of CSDH increases in such cases. Much of the literature has supported the preventive role of middle meningeal artery (MMA) embolization in recurrent CSDH. We report a 13-year-old male patient with recurrent CSDH and AC where the early intervention of MMA embolization was proven effective in preventing the further recurrence of CSDH.

Abstract
Craniotomy is frequently used for the treatment of acute subdural hematoma; however, it the procedure exhibits a high mortality rate. Preoperative trepanation and drainage in an emergency ward may reduce intracranial pressure, shorten operation time and lower patient mortality, and is thus applicable to the treatment of acute subdural hematoma. The present study reports the cases of two elderly patients that benefitted from trepanation and drainage of an acute subdural hematoma. In each case, the family members of the patients refused to consent to a craniotomy; thus, burr-hole drainage was selected as an alternative option for relieving intracranial pressure. The risks require careful evaluation when considering whether trepanation with drainage is an option for a patient. Following treatment, the two cases were cured and discharged on days 48 and 18 after admission, respectively. The present case studies indicate that trepanation with drainage may be a promising approach for reducing craniotomy-associated mortality and closely monitoring condition variation in elderly patients. Following trepanation with drainage, certain patients do not undergo a craniotomy.

Abstract
Chronic subdural hematomas (CSDH), which are frequently encountered in neurosurgical practice, are, in the majority of cases, ideally treated with surgical drainage. Despite this common practice, there is still controversy surrounding the best surgical procedure. With lack of clear evidence of a superior technique, surgeons are free to base the decision on other factors that are not related to patient care. A retrospective chart review of 119 patients requiring surgical drainage of CSDH was conducted at a large tertiary care center over a three-year period. Of the cases reviewed, 58 patients underwent craniotomy, while 61 patients underwent burr hole washout. The study focused on re-operation rates, mortality, and morbidity, as measured by Glasgow coma scores (GCS), discharge Rankin disability scores, and discharge disposition. Secondary endpoints included length of stay and cost of procedure. Burr hole washout was superior to craniotomy with respect to patient outcome, length of stay and recurrence rates. In both study groups, patients required additional surgical procedures (6.6% of burr hole patients and 24.1% of craniotomy patients) (P = 0.0156). Of the patients treated with craniotomy, 51.7% were discharged home, whereas 65.6% of the burr hole patients were discharged home. Patients who underwent burr hole washout spent a mean of 78.8 minutes in the operating suite while the patients undergoing craniotomy spent 129.4 minutes (P < 0.001). The difference in mean cost per patient, based solely on operating time, was $2,828 (P < 0.001). This does not include the further cost due to additional procedures and hospital stay. The mean length of stay after surgical intervention was 3 days longer for the craniotomy group (P = 0.0465). Based on this retrospective study, burr hole washout is superior for both patients’ clinical and financial outcome; however, prospective long-term multicenter clinical studies are required to verify these findings.

Abstract
ABSTRACTBackground: Recurrence of chronic subdural haematomas (CSDHs) after surgical drainage is a significant problem with rates up to 20%. This study focuses on determining factors predictive of haematoma recurrence and presents a scoring system stratifying recurrence risk for individual patients. Methods: Between the years 2005 and 2009, 331 consecutive patients with CSDHs treated with surgery were included in this study. Univariate and multivariate analyses were performed searching for risk factors of increased post-operative haematoma volume and haematoma recurrence requiring repeat drainage. Results: We found a 12% reoperation rate. CSDH septation (seen on computed tomogram scan) was found to be an independent risk factor for recurrence requiring reoperation (p=0.04). Larger post-operative subdural haematoma volume was also significantly associated with requiring a second drainage procedure (p<0.001). Independent risk factors of larger post-operative haematoma volume included septations within a CSDH (p<0.01), increased pre-operative haematoma volume (p<0.01), and a greater amount of parenchymal atrophy (p=0.04). A simple scoring system for quantifying recurrence risk was created and validated based on patient age (< or ≥80 years), haematoma volume (< or ≥160cc), and presence of septations within the subdural collection (yes or no). Conclusion: Septations within CSDHs are associated with larger post-operative residual haematoma collections requiring repeat drainage. When septations are clearly visible within a CSDH, craniotomy might be more suitable as a primary procedure as it allows greater access to a septated subdural collection. Our proposed scoring system combining haematoma volume, age, and presence of septations might be useful in identifying patients at higher risk for recurrence.

Abstract
Subdural effusion (SDE) in an infant is a rare clinical scenario, which may be secondary to a variety of etiologies. Massive SDE is an extremely rare complication of head injury. It usually runs a self-limiting course. Though neurosurgical intervention is occasionally needed, different methods of surgical procedure for management includes burr-hole alone, burr-holes with subdural drain placement, twist drill craniotomy with drain and even craniotomy. The authors report a rare case of progressive massive SDE, which despite bilateral burr-hole placement and drainage failed and presented with visual deterioration and massive bulge of scalp at burr-hole sites producing rabbit ear sign in a 10 month old infant. Ultimately cystoperitoneal shunt was carried out in a desperate attempt to prevent impending rupture of scalp sutures at sites of previous burr-hole placement. Astonishingly not only complete resolution of hygroma, but visual recovery also took place. Patient is doing well at 6 months following shunt with regaining normal vision and appropriate developmental milestones. A magnetic resonance imaging scan of brain at last follow-up revealed mild ventriculomegaly with subduro-peritoneal shunt in situ and rest of brain was unremarkable. Such cases have not been reported in literature until date.

Abstract
The aim of the study is to evaluate the efficacy of craniotomy and membranectomy as initial treatment of organized chronic subdural hematoma (OCSH). We retrospectively reviewed a series of 34 consecutive patients suffering from OCSH, diagnosed by magnetic resonance imaging (MRI) or contrast computer tomography (CCT) in order to establish the degree of organization and determine the intrahematomal architecture. The indication to perform a primary enlarged craniotomy as initial treatment for non-liquefied chronic subdural hematoma (CSDH) 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. The reason why some hematomas evolve towards a complex and organized architecture remains unclear; the most common aspect to come to light was the “long standing” of the CSDHs which, in our series, had an average interval of 10 weeks between head injury and initial scan. Recurrence was found to have occurred in 2 patients (6% of cases) in the form of acute subdural hematoma. One patient died as the result of an intraventricular and subarachnoid haemorrhage, while 2 patients (6%) suffered an haemorrhagic stroke ipsilateral to the OCSH. Eighty-nine percent of cases had a good recovery, while 11% remained unchanged or worsened. In select cases, based on the MRI appearance, primary enlarged craniotomy seems to be the treatment of choice for achieving a complete recovery and a reduced recurrence rate in OCSH.

Abstract
BACKGROUND Subdural hematoma (SDH) is a common disease entity treated by neurosurgical intervention. Although the incidence increases in the elderly population, there is a paucity of studies examining their surgical outcomes. OBJECTIVES To determine the neurological and functional outcomes of patients over 70 years of age undergoing surgical decompression for subdural hematoma. MATERIALS AND METHODS We retrospectively reviewed data on 45 patients above 70 years who underwent craniotomy or burr holes for acute, chronic or mixed subdural hematomas. We analyzed both neurological and functional status before and after surgery. RESULTS Forty-five patients 70 years of age or older were treated in our department during the study period. There was a significant improvement in the neurological status of patients from admission to follow up as assessed using the Markwalder grading scale (1.98 vs. 1.39; P =0.005), yet no improvement in functional outcome was observed as assessed by Glasgow Outcome Score. Forty-one patients were admitted from home, however only 20 patients (44%) were discharged home, 16 (36%) discharged to nursing home or rehab, 6 (13%) to hospice and 3 (7%) died in the postoperative period. Neurological function improved in patients who were older, had a worse pre-operative neurological status, were on anticoagulation and had chronic or mixed acute and chronic hematoma. However, no improvement in functional status was observed. CONCLUSION Surgical management of SDH in patients over 70 years of age provides significant improvement in neurological status, but does not change functional status.

"Rabbit ear" scalp deformity caused by massive subdural effusion in infant following bilateral bur-hole drainage failure: successfully managed with subduro-peritoneal shunt. Childs Nerv Syst 2013; 29:1993-6.

Abstract
INTRODUCTION Subdural effusion in an infant is a rare clinical scenario which may be secondary to a variety of etiologies. Massive subdural effusion is an extremely rare complication of head injury. CASE REPORT Authors report a rare case of progressive massive subdural effusion which, despite bilateral bur-hole placement and drainage, failed and presented with visual deterioration and massive bulge of the scalp at bur-hole sites, producing a rabbit ear appearance in a 10-month-old infant. Ultimately, cystoperitoneal shunt was carried out in a desperate attempt to prevent impending rupture of scalp sutures at sites of previous bur-hole placement. This was followed by not only complete resolution of hygroma but also visual recovery. The patient is doing well at 6 months following shunt, regaining normal vision and appropriate developmental milestones. A MRI scan of the brain was carried out at last follow-up, which revealed mild ventriculomegaly with the rest of the brain being unremarkable, and subduro-peritoneal shunt in situ. Such a case has not been reported in the literature till date. DISCUSSION Subdural effusion usually runs a self-limiting course. Though neurosurgical intervention is occasionally needed, different methods of surgical procedure for management include bur hole alone, bur holes with subdural drain placement, twist drill craniotomy with drain, and even craniotomy. Various methods of management are discussed along with a review of pertinent literature.

Abstract
OBJECTIVE Chronic subdural hematoma (cSDH) has an increasing incidence and results in high morbidity and mortality. We review here the 10-year experience of a single institution and the literature regarding the treatment and major associations of cSDH. METHODS We retrospectively reviewed all cSDHs surgically treated from 2000 to 2010 in the New York Harbor Health Care System to evaluate the duration from admission to treatment, type of treatment, length of stay (LOS) in critical care, LOS in the hospital, and recurrence. The literature was reviewed with regards to incidence, associations, and treatment of cSDH. RESULTS From 2000 to 2008, 44 patients were treated with burr holes (BHs). From 2008 to 2010, 29 patients were treated with twist-drill evacuation (subdural evacuating port system, SEPS). Four patients from each group were readmitted for reoperation (9% vs 14%; P = 0.53). The average time to intervention for SEPS (11.2 ± 15.3 hours) was faster than for BHs (40.3 ± 69.1 hours) (P = 0.02). The total hospital LOS was shorter for SEPS (9.3 ± 6.8 days) versus BHs (13.4 ± 10.2 days) (P = 0.04); both were significantly longer than for a brain tumor patient undergoing craniotomy (7.0 ± 0.5 days, n = 94, P < 0.01). CONCLUSION Despite decreasing LOSs as treatment for cSDH evolved from BHs to SEPS, the LOS for a cSDH is still longer than that of a patient undergoing craniotomy for brain tumor. We noted 11% recurrence in our series of patients, which included individuals who recurred as late as 3 years after initial diagnosis.

Abstract
OBJECTIVE The population suffering from chronic/subacute subdural hematomas (SDHs) generally includes elderly patients with co-morbidities; therefore the success of less invasive surgical techniques has been of long standing interest. The optimum treatment option for chronic/subacute SDH has not been well established. We report our retrospective outcomes of SDH drainage through a subdural evacuating port system (SEPS). PATIENTS AND METHODS Fifty-two consecutive adult patients with chronic/subacute SDH treated with SEPS (total 64 procedures), over a period of 3 years (June 2006-June 2009), were included. 9/52 patients had SEPS performed for bilateral SDHs. Three patients had SEPS placed for recurrent SDH. This retrospective study was approved by the Institutional Review Board of SUNY Upstate Medical University and Crouse Hospital. RESULTS Overall 38/52 patients (73%) showed clinical improvement, 10/52 patients (19%) did not show any clinical improvement and 4/52 (8%) patients became clinically worse after the SEPS placement during initial hospitalization. 41/52 patients, treated initially with SEPS were followed as outpatients. 32/41 patients improved, returning to baseline neurological status, 5/41 patients improved, but still had some residual symptoms. The remaining 4/41 patients, presented with recurrent symptoms and had recurrent SDH on CT scans. During the in-hospital post-SEPS period, 8 SDH had >75% decrease, 17 SDH had between 50 and 75% decrease, 23 SDH had between 25 and 50% decrease and 14 procedures had <25% decrease in maximal width of the SDH on postoperative scans. Outpatient follow up CT scans after SEPS placement were available for 46/64 procedures. At final outpatient follow up, 33/46 SDHs showed >75% decrease in maximal thickness, 4/46 SDH showed between 50 and 75% and 2/46 SDH showed between 25 and 50% decreases in maximal width of chronic SDH. However, in 7/46 patients, SDH re-accumulated (i.e. increased in thickness) as outpatients, after initial response to treatment on post-operative in-hospital CT scans. CONCLUSION SEPS is an effective, relatively safe and convenient treatment strategy with low invasiveness; among management options of chronic/subacute SDH.

Abstract
BACKGROUND Burr-hole drainage has become the accepted treatment of choice for chronic subdural haematoma (cSDH), although still burdened with a major recurrence rate. The current analysis was initiated to determine management-related risk factors for recurrence, i.e. postoperative low-molecular-weight heparin thromboprophylaxis, and the importance of rinsing the subdural space. METHODS Two-hundred and forty-seven patients with computerised tomography (CT) defined symptomatic cSDH were managed by two burr-hole trepanations and drainage between January 2005 and November 2008. Postoperative thromboprophylaxis with 40 mg enoxaparine daily was given only during the first half of the study period. For the current analysis the amount of rinsing fluid, postoperative low-dose thromboprophylaxis, as well as age and gender, bilaterality, preoperative and postoperative blood coagulation studies, platelet counts and decrease of subdural fluid on early postoperative CT, were recorded and correlated with recurrence. Statistical calculation was done by univariate and multivariate analysis. RESULTS A total of 62 of 247 patients needed revision surgery for recurrence (25.1 %). Recurrence rates were significantly lower in the patients treated without postoperative enoxaparine (18.84 %) than in the group with postoperative low-dose enoxaparine thromboprophylaxis (32.11 %) and enoxaparine was administered in a higher proportion of the patients suffering recurrence (P = 0.013). A median intraoperative irrigation volume of 863 ml saline was used in the patients suffering recurrence and 1,500 ml in patients without recurrence (P < 0.001). The median age was slightly higher in the patients suffering from recurrence. Male gender predominated in both groups but was slightly more pronounced in the recurrence group. Preoperative and postoperative platelet counts and plasmatic coagulation indices did not differ significantly between the groups. Relative residual subdural fluid collection on early postoperative CT remained larger in patients finally suffering recurrence (P = 0.03). Multivariate analysis confirmed a small amount of rinsing fluid, male gender and the use of enoxaparine as the most important risk factors for recurrence, although that latter factor did not reach statistical significance in the multivariate analysis. CONCLUSIONS The investigation provides evidence that copious intraoperative irrigation and avoidance of postoperative low-molecular-weight heparin thromboprophylaxis may reduce the recurrence rate of cSDH.

Abstract
Background The treatment of chronic subdural hematoma (cSDH) is still charged of significant risk of hematoma recurrence. Patient-related predictors and the surgical procedures themselves have been addressed in many studies. In contrast, postoperative management has infrequently been subjected to detailed analysis. Moreover variable intravenous fluid administration (IFA) was not reported in literature till now in the context of cSDH treatment. Methodology/Principal Findings A total of 45 patients with cSDH were operated in our department via two burr hole craniostomy within one calendar year. Downward drainage was routinely left in hematoma cavity for a one day. Independent variables selected for the analysis were related to various aspects of patient management, including IFA. Two dependent variables were chosen as measure of clinical course: the rate of hematoma recurrence (RHR) and neurological status at discharge from hospital expressed in points of Glasgow Outcome Scale (GOS). Univariate and multivariate regression analyses were performed. Hematoma recurrence with subsequent evacuation occurred in 7 (15%) patients. Univariate regression analysis revealed that length of IFA after surgery influenced both dependent variables: RHR (p = 0.045) and GOS (p = 0.023). Multivariate regression performed by backward elimination method confirmed that IFA is a sole independent factor influencing RHR. Post hoc dichotomous division of patients revealed that those receiving at least 2000 ml/day over 3 day period revealed lower RHR than the group with less intensive IFA. (p = 0.031). Conclusions/Significance IFA has been found to be a sole factor influencing both: RHR and GOS. Based on those results we may recommend administration of at least 2000 ml per 3 days post-operatively to decrease the risk of hematoma recurrence.

Abstract
OBJECT Various surgical interventions have been described to evacuate chronic subdural collections (CSCs) of infancy. These include transfontanel percutaneous aspiration, subdural drains, placement of bur hole(s) with or without a subdural drain, and shunting. Shunt placement typically provides good long-term success (resolution of the subdural fluid), but comes with well-known early and late complications. Recently, the authors have used a mini-osteoplastic craniotomy technique with the goal of definitively treating these children with a single surgery while avoiding the many issues associated with a shunt. They describe their procedure and compare it with the traditional bur hole technique. METHODS In this single-institution retrospective study, the authors evaluated 26 cases involving patients who underwent treatment for CSC. Preoperative, intraoperative, and postoperative data were reviewed, including radiographic findings (density of the subdural fluid and ventricular and subarachnoid space size), neurological examination findings, and intraoperative fluid description. The primary outcome was treatment failure, defined as the patient requiring any subsequent surgical intervention after the index procedure (minicraniotomy or bur hole placement). RESULTS Fifteen patients (10 male and 5 female; median age 5.1 months) collectively underwent 27 minicraniotomy procedures (each procedure representing a hemisphere that was treated). In the bur hole group, there were 11 patients (6 male and 5 female; median age 4.6 months) with 18 hemispheres treated. Both groups had subdural drains placed. The average follow-up for each treatment group was just over 7 months. Treatment failure occurred in 2 patients (13%) in the minicraniotomy group compared with 5 patients (45%) in the bur hole group (p = 0.09). Furthermore, the 2 patients who had treatment failure in the minicraniotomy group required 1 subsequent surgery each, whereas the 5 in the bur hole group needed a total of 9 subsequent surgeries. Eventually, 80% of the patients in the minicraniotomy group and 70% of those in the bur hole group had resolution of the subdural collections on the last imaging study. CONCLUSIONS The minicraniotomy technique may be a superior technique for the treatment of CSCs in infants compared with bur hole evacuation. The minicraniotomy provides greater visualization of the subdural space and allows more aggressive evacuation of the fluid, better irrigation of the space, the ability to fenestrate any accessible membranes safely, and continued egress of fluid into the subgaleal space. Although this preliminary report has obvious limitations, evaluation of this technique may be worthy of a prospective, multiinstitutional collaborative effort.

Abstract
Chronic subdural hematoma (cSDH) is an increasingly common neurological disease process. Despite the wide prevalence of cSDH, there remains a lack of consensus regarding numerous aspects of its clinical management. We provide an overview of the epidemiology and pathophysiology of cSDH and discuss several controversial management issues, including the timing of post-operative resumption of anticoagulant medications, the effectiveness of anti-epileptic prophylaxis, protocols for mobilization following evacuation of cSDH, as well as the comparative effectiveness of the various techniques of surgical evacuation. A PubMed search was carried out through October 19, 2010 using the following keywords: "subdural hematoma", "craniotomy", "burr-hole", "management", "anticoagulation", "seizure prophylaxis", "antiplatelet", "mobilization", and "surgical evacuation", alone and in combination. Relevant articles were identified and back-referenced to yield additional papers. A meta-analysis was then performed comparing the efficacy and complications associated with the various methods of cSDH evacuation. There is general agreement that significant coagulopathy should be reversed expeditiously in patients presenting with cSDH. Although protocols for gradual resumption of anti-coagulation for prophylaxis of venous thrombosis may be derived from guidelines for other neurosurgical procedures, further prospective study is necessary to determine the optimal time to restart full-dose anti-coagulation in the setting of recently drained cSDH. There is also conflicting evidence to support seizure prophylaxis in patients with cSDH, although the existing literature supports prophylaxis in patients who are at a higher risk for seizures. The published data regarding surgical technique for cSDH supports primary twist drill craniostomy (TDC) drainage at the bedside for patients who are high-risk surgical candidates with non-septated cSDH and craniotomy as a first-line evacuation technique for cSDH with significant membranes. Larger prospective studies addressing these aspects of cSDH management are necessary to establish definitive recommendations.
