Abstract
BACKGROUND The surgical techniques for treatment of chronic subdural hematoma (CSDH), a common neurosurgical condition, have been discussed in a lot of clinical literature. However, the recurrence proportion after CSDH surgery remains high, ranging from 10 to 20%. The standard surgical procedure for CSDH involves a craniostomy to evacuate the hematoma, but irrigating the hematoma cavity during the procedure is debatable. The authors hypothesized that the choice of irrigation fluid might be a key factor affecting the outcomes of surgery. This multicenter randomized controlled trial aims to investigate whether intraoperative irrigation using artificial cerebrospinal fluid (ACF) followed by the placement of a subdural drain would yield superior results compared to the placement of a subdural drain alone for CSDH. METHODS The study will be conducted across 19 neurosurgical departments in Japan. The 1186 eligible patients will be randomly allocated to two groups: irrigation using ACF or not. In either group, a subdural drain is to be placed for at least 12 h postoperatively. Similar to what was done in previous studies, we set the proportion of patients that meet the criteria for ipsilateral reoperation at 7% in the irrigation group and 12% in the non-irrigation group. The primary endpoint is the proportion of patients who meet the criteria for ipsilateral reoperation within 6 months of surgery (clinical worsening of symptoms and increased hematoma on imaging compared with the postoperative state). The secondary endpoints are the proportion of reoperations within 6 months, the proportion being stratified by preoperative hematoma architecture by computed tomography (CT) scan, neurological symptoms, patient condition, mortality at 6 months, complications associated with surgery, length of hospital stay from surgery to discharge, and time of the surgical procedure. DISCUSSION We present the study protocol for a multicenter randomized controlled trial to investigate our hypothesis that intraoperative irrigation with ACF reduces the recurrence proportion after the removal of chronic subdural hematomas compared with no irrigation.

Front Neurol 2023; 14:1218334.

Abstract
Purpose To systematically review the different types of irrigation fluid and the different temperatures of irrigation fluid on postoperative recurrence rates in the evacuation of chronic subdural hematoma (CSDH). Methods We conducted a comprehensive search of electronic databases, including PubMed, Embase, the Cochrane Library, the China National Knowledge Infrastructure (CNKI), WanFang, the Chinese VIP Information (VIP), and China Biology Medicine (CBM), and reference lists of relevant studies to identify all eligible studies. Two reviewers independently screened the titles and abstracts for inclusion, and the full-text articles were assessed for eligibility based on predetermined inclusion and exclusion criteria. Data were extracted using a standardized form, and the quality of the studies was assessed using a risk of bias tool. Meta-analyses were performed using a fixed-or random-effects model, and heterogeneity was assessed using the I2 statistic. The primary endpoint was the postoperative recurrence rate. Results After stringent screening, a total of 11 studies were identified, including six English publications, four Chinese publications, and one Japanese publication, involving a population of 29,846 patients. Our meta-analysis provides evidence that artificial cerebrospinal fluid (ACF) could decrease the post-operative recurrence rate by 47% after the evacuation of CSDH when compared to normal saline (NS) [(odds ratio) OR 0.53, 95% confidence intervals (CI): 0.31-0.90, p = 0.02, I2 = 67%]. Besides, the irrigation fluid at body temperature could decrease the postoperative recurrence rate of CSDH by 64% when compared to room temperature (OR = 0.36, 95% CI = 0.22-0.59, p < 0.0001, I2 = 0%). Conclusion Our analysis revealed significant difference in the choice of irrigation fluid for CSDH surgery. Notably, we found that irrigation with fluid at body temperature demonstrated superiority over irrigation with fluid at room temperature, resulting in fewer instances of recurrence. This straightforward technique is both safe and widely available, providing an opportunity to optimize outcomes for patients with CSDH. Our findings suggest that the use of body-temperature NS or ACF of room temperature during operation should be considered a standard of procedure in CSDH surgery. Nevertheless, whether the different temperature of ACF could be considered a standard of procedure in CSDH surgery still need high-quality RCTs to further identify.

Artificial cerebrospinal fluid use during burr-hole surgery and reoperation rate in patients with chronic subdural hematoma: an analysis using a nationwide inpatient database. Acta Neurochir (Wien) 2023; 165:1289-1296. [PMID: 36991171 PMCID: PMC10140006 DOI: 10.1007/s00701-023-05570-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Accepted: 03/17/2023] [Indexed: 03/31/2023]
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
In this paper, I review the historical changes in the etiological concepts and surgical treatments for chronic subdural hematoma (CSDH) across the world and in Japan. I also examine future problems associated with its surgical procedures and medical costs. CSDH was first reported by Wepfer in 1657 as "delayed apoplexy." In 1857, Virchow described the famous concept of so-called "pachymeningitis hemorrhagica interna." He considered that the etiology of CSDH involved inflammation. In 1914, Trotter described the origin of CSDH as traumatic. Currently, CSDH is considered to arise with a first leak of blood from dural border cells after mild trauma. Inflammatory cells are then drawn to the border cell layer. At this point, new membranes form from activated inflammation; then, the hematoma enlarges, promoted by angiogenic factors and new capillaries. In 1883, Hulke reported successful trepanning of a patient with CSDH. Burr holes and craniotomy for removal of the hematoma were subsequently reported, and new methods were developed over the course of several decades around the world. In Japan, after the first report by Nakada in 1938, many Japanese pioneering figures of neurological surgery have studied CSDH. After Mandai reported the middle meningeal artery embolization in 2000, this method is now considered useful as an initial or second treatment for CSDH. However, the age of patients is increasing, so more minimally invasive surgeries and useful pharmacotherapies are needed. We must also consider the costs for treating CSDH, because of the increasing numbers of surgical cases.

Abstract
OBJECTIVE This study aimed to evaluate the efficacy and safety of half-saline (HS) serum as an irrigation solution in chronic subdural hematoma (CSDH) surgery using the burr hole craniostomy (BHC) technique. METHODS This randomized clinical trial was conducted in university hospital referral centers from 2020 to 2021. Sixty-three patients with CSDH eligible for BHC were primarily enrolled. Two patients were excluded because of concurrent stroke. Sixty-one patients were randomly allocated into case (HS=30) and control (normal-saline [NS]=31) groups. HS was used to irrigate the hematoma in the case group and NS was used in the control group. The patients were followed-up. Clinical variables including demographic and medical findings, postoperative computed tomography findings, postoperative complications, hospitalization period, recurrence rate, and functional status measured by the Barthel type B index were recorded. RESULTS Forty-six of 61 patients were male (75.4%), and the patients' mean age was 65.4±16.9 years, with equal distribution between the 2 groups. Postoperative effusion and postoperative hospital stay duration were significantly lower in the HS group than in the NS group (p=0.002 and 0.033, respectively). The postoperative recurrence within 3 months in both groups was approximately equal (6.6%). In terms of functional outcomes and postoperative complications, HS showed similar results to those of NS. CONCLUSION HS as an irrigation fluid in BHC effectively reduced postoperative effusion and hospital stay duration without considerable complications.

Abstract
BACKGROUND Chronic subdural hematoma (CSDH) is a common neurological disease, and the surgical evacuation of subdural collection remains the primary treatment approach for symptomatic patients. Postoperative recurrence is a serious complication, and several factors are correlated with postoperative recurrence. METHODS We searched Embase, Web of Science, PubMed, and Cochrane Library from their establishment to September 2020. Reports on randomized, prospective, retrospective, and overall observational studies on the management of surgical patients with CSDH were searched, and an independent reviewer performed research quality assessment. Factors that affect the postoperative recurrence of CSDH were extracted: social demographics, drugs (as the main or auxiliary treatment), surgical management, imaging, and other risk factors. We evaluated the recurrence rate of each risk factor. A random effect model was used to perform a meta-analysis, and each risk factor affecting the postoperative recurrence of CSDH was then evaluated and graded. FINDINGS In total, 402 studies were included in this analysis and 32 potential risk factors were evaluated. Among these, 21 were significantly associated with the postoperative recurrence of CSDH. Three risk factors (male, bilateral hematoma, and no drainage) had convincing evidence. The classification of evidence can help clinicians identify significant risk factors for the postoperative recurrence of CSDH. INTERPRETATION Only few associations were supported by high-quality evidence. Factors with high-quality evidence may be important for treating and preventing CSDH recurrence. Our results can be used as a basis for improving clinical treatment strategies and designing preventive methods. FUNDING No funding was received.

Abstract
Background: We routinely measured the exact chronic subdural hematoma (CSDH) volume during single burr hole surgery. To date, several risk factors have been reported for CSDH recurrence, including sex, hematoma volume and degree of midline shift calculated from computed tomography, use of anticoagulants or antiplatelet medications, and alcohol consumption habits. The aim of this study was to clarify whether hematoma volume, in conjunction with other factors, can predict recurrence. Methods: We retrospectively reviewed the clinical data of 194 consecutive patients with CSDH who underwent single burr hole surgery. The risk factors for recurrence were analyzed based on patients’ sex, age, bilaterality, existence of apparent trauma history, exact intraoperative hematoma volume, and various clinical factors, including preoperative anticoagulant/antiplatelet intake. Results: Recurrence occurred in 22 patients (11.3%). Multivariate logistic regression analysis revealed that intraoperative hematoma volume was an independent risk factor for CSDH recurrence (odds ratio [OR], 1.01; 95% confidence interval [CI], 1.01–1.02, P < 0.001), in addition to sex (male) (OR 9.25; 95% CI, 1.00–84.8; P = 0.049) and diabetes mellitus (DM) (OR: 3.97, 95% CI, 1.34–11.7, P = 0.013). Based on receiver operating characteristics analysis, the cutoff value of the hematoma volume predicting CSDH recurrence was 150 ml (sensitivity and specificity of 72.7% and 72.1%, respectively; area under the curve: 0.7664, 95% CI: 0.654–0.879, P < 0.001). Of these, a hematoma volume ≥150 mL was the strongest independent risk factor for recurrence according to multiple regression (OR: 8.98, 95% CI: 2.73–29.6, P < 0.001) and Cox regression analysis (hazard ratio: 3.05, 95% CI: 1.18–7.87, log-rank P = 0.0046, P = 0.021). Follow-up periods after surgery were significantly longer for cases with recurrence than for non-recurrence cases (24.8 ± 11.5 vs. 15.9 ± 9.7 days), and the recurrence prediction cutoff value was 17 days, with a sensitivity and specificity of 83.1% and 68.2%, respectively (AUC: 0.7707, 95% CI: 0.6695–0.8720, P < 0.001). Conclusion: Intraoperative hematoma volume could be a predictive value for CSDH recurrence.

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

Abstract
Chronic subdural hematoma (CSDH) is a common disease in older individuals with a substantial rate of recurrence. The mechanism of CSDH recurrence remains unclear. This study aimed to detect imaging parameters that could indicate the risk for CSDH recurrence by using quantitative volumetric analysis and computed tomography (CT) texture analysis (CTTA). Clinical and imaging parameters were retrospectively investigated in 147 newly diagnosed CSDH lesions in 114 patients surgically treated at the Keio University Hospital during a 6-year period. For CT images, quantitative volumetric and texture analyses were performed. Hematoma volume, postoperative air volume, hematoma density, and texture parameters including kurtosis, skewness, and entropy were evaluated and compared with CSDH recurrence rate. Data were statistically evaluated, and a difference of p < 0.05 was considered significant. Reoperation for CSDH recurrence was required in 27 sides (18.4%) of 26 patients. Multivariate analysis showed that postoperative hematoma volume and postoperative hematoma density were independent risk factors for symptomatic CSDH recurrence that required reoperation. Postoperative hematoma volume, postoperative significant residual air, and postoperative hematoma density were also identified as independent risk factors for potential CSDH recurrence. Preoperative hematoma entropy was prone to be associated with both symptomatic and potential CSDH recurrence in univariate analysis, but not in multivariate analysis because of confounding factors. Quantitative volumetric analysis and CTTA could aid in distinguishing individuals at risk for CSDH recurrence.

Abstract
Objectives Cerebral vasospasm after subarachnoid haemorrhage (SAH) is associated with cerebrovascular contractile receptor upregulation resulted from haemolysis in the subarachnoid space. This study developed a new magnesium-rich artificial cerebrospinal fluid (MACSF) formula and investigated its effects on receptor-mediated contraction in rat basilar arteries. Methods Clear and haemorrhagic cerebrospinal fluid (CSF) were collected from patients with hydrocephalus or SAH. MACSF was freshly prepared using clinical intravenous injections. Rat basilar arteries were segmented and incubated with clear CSF, haemorrhagic CSF or MACSF. The contractile responses were studied by myograph. The messenger ribonucleic acid (mRNA) and protein expression of 5-hydroxytryptamine 1B (5-HT1B), endothelin subtype B (ETB) and endothelin subtype A (ETA) receptors were evaluated by real-time polymerase chain reaction (PCR) and Western blot analyses. Results Haemorrhagic CSF exposure shifted the contractile curves induced by 5-hydroxytryptamine (5-HT), sarafotoxins 6c (S6c) and endothelin-1 (ET-1) leftward with increased maximal contraction values. Furthermore, mRNA and protein expression were markedly elevated for 5-HT1B, ETB and ETA receptors on arteries exposed to haemorrhagic CSF. However, the contractile responses to 5-HT, S6c or ET-1 and expression of 5-HT1B, ETB and ETA receptors in rat cerebral arteries exposed to MACSF remained unaffected compared to those exposed to clear CSF. Besides, unlike normal saline which can inactive in-vitro vessels, MACSF can maintain their physiological activity. Conclusion Haemorrhagic CSF induces upregulation of 5-HT1B, ETB and ETA receptors in rat cerebral arteries. However, MACSF can maintain in-vitro rat basilar arteries in good physiological activity and normal expression of contractile 5-HT and ET receptors.

Abstract
OBJECTIVES Pneumocephalus is a common operative complication of chronic subdural hematoma. This study is to analyze the relationship between postoperative pneumocephalus and the recurrence and surgical outcomes. PATIENTS AND METHODS This is a retrospective case-cohort study, including a pneumocephalus group (n = 46) and a control group (n = 181). Their recurrence rates, CT attenuation values, hospital stay, healing time and the neurological status were recorded and analyzed. RESULTS The pneumocephalus group had a recurrence rate of 32.6%, significantly higher than the control (17.7%). In addition, the pneumocephalus group had a higher rate of postoperative epilepsy (21.7% vs 3.3%), longer hospital stay (11.5 ± 2.8 vs 7.8 ± 1.2 days), longer healing time (10.8 ± 5.4 vs 6.5 ± 2.3 months), and worse neurological scores than the control. CONCLUSION Pneumocephalus increases the recurrence rate of chronic subdural hematoma, and it not only prolongs the hospital stay and healing time, but also leads to deterioration of the neurological status.

Abstract
Background: There are no current standard operative steps for chronic subdural hematoma (CSDH). The aim of this study was to detect the recurrence rate after drainage of a unilateral diffuse CSDH by combining certain operative steps. Materials and Methods: This is a descriptive, retrospective cohort study that included 47 consecutive adult patients who underwent evacuation of a unilateral diffuse CSDH by two large burr holes (≥2 cm in diameter) and irrigation of the subdural space by warm saline, followed by placement of a subgaleal Redivac drain under low-pressure suction in our university hospital from August 2012 to August 2016. There were 29 men and 18 women with a mean age of 69.1 years. Results: All the operations were uneventful. All the patients had adequate drainage of their subdural hematomas, and all patients were discharged alert and oriented. No incidence of recurrence within 12 months after surgery. Conclusion: This study demonstrated that surgical management of a unilateral diffuse CSDH in adult patients by two large burr holes, irrigation, and a subgaleal Redivac low-pressure suction drainage was effective and associated with no recurrence.

Abstract
Over the decades, the problem of postoperative recurrence of chronic subdural hematoma (CSDH) has not been resolved. The objective of our study was to investigate whether the recurrence rate of CSDH is decreased when artificial cerebrospinal fluid (ACF) is used as irrigation solution for CSDH surgery. The present study was a multi-center, prospective, randomized, open parallel group comparison test of patients enrolled from 10 hospitals in Japan. Eligible patients with CSDH were randomly assigned to undergo burr hole drainage with either normal saline (NS) or ACF irrigation. The primary end-point was postoperative recurrence of ipsilateral CSDH. A total of 402 patients with newly diagnosed CSDH were enrolled during the study period. After applying inclusion and exclusion criteria, and taking into consideration cases lost to follow-up, our final study cohorts consisted of 177 ACF patients and 165 NS patients, representing 85.7% of the initial cohort. The overall recurrence rate was 11.4%, occurring in 39 of the 342 analyzed patients during 90 days of follow-up. Recurrence rates in the ACF and NS groups were 11.9% (21 of 177) and 10.9% (18 of 165), respectively. No significant difference was evident between groups (p = 0.87). In addition, no significant difference in time to recurrence was seen between groups (p = 0.74). No serious adverse effects related to irrigation fluid were seen in either group. Regarding the irrigation fluid for CSDH surgery, no differences in recurrence rate or time to recurrence were seen between the ACF and NS groups. However, ACF offers sufficient safety as irrigation fluid for CSDH.

Abstract
OBJECTIVE Numerous studies have investigated different operative procedures for treating chronic subdural hematoma (CSDH); however, the results are controversial. This meta-analysis was performed to evaluate the efficacy of burr hole drainage without irrigation (BHD) and burr hole drainage with irrigation (BHDI) for CSDH. METHODS We searched the following electronic databases to identify all studies from their inception to September 2017: Cochrane Library, Science Direct, MEDLINE, EMBASE, Scopus, Google Scholar, the China Biomedical Database (CBM), and the Chinese National Knowledge Infrastructure (CNKI). Randomized clinical trials (RCTs), prospective cohort studies, retrospective observational cohort studies, and case-control studies investigating BHD and BHDI for the treatment of CSDH were included. The Cochrane Collaboration's RevMan 5.3 software was used for meta-analysis. RESULTS In total, 7 retrospective cohort studies and 2 RCTs involving 993 participants were included. Comprehensive analysis results of 9 studies indicated that the recurrence of the BHDI was similar to that in BHD (odds ratio [OR] = 1.27, 95% confidence interval [CI] = .61-2.63, P = .53). Moreover, analysis for comparing recurrence in the 2 RCTs was not significantly different (OR = 1.14, 95% CI = .16-8.24, P = .95).In addition, meta-analysis of pneumocephalus (OR = 5.91, 95% CI = .61-56.86, P = .12) and mortality (OR = 0.94, 95% CI 0.14-6.16, P = .95) was not significantly different. CONCLUSIONS The results of this meta-analysis demonstrated that procedures with or without irrigation in the treatment of CSDH might have similar effect regarding recurrence and complications; therefore, irrigation might not be necessary. However, well-conducted RCTs and high-quality observational studies are still required to corroborate this issue.

Abstract
BACKGROUND The study of age-related diseases like chronic subdural hematoma (CSDH) is of high interest, considered the general ageing of the population. This investigation aimed to identify the main clinical characteristics of CSDH patients, to evaluate the impact of the disease on quality of life, its treatment and comorbidities/complications and to compare our data with other surgical series published over the past 5 years. METHODS A retrospective cohort study including all consecutive patients operated for CSDH between January 1, 2006 and December 31, 2013 at the Unit of Neurosurgery of our hospital was carried out. RESULTS 605 patients were included in the study (66.0% male, mean age 77.5±10.5 years). History of brain trauma was reported in 65.6%. Common comorbidities were hypertension (59.0%), cardiopathies (36.0%), and previous stroke (23.6%). Clotting and coagulation alterations were present in 27.2% and 17.0%, respectively. In 24.0% of cases, the hematoma was bilateral. 17.3% had more than one surgery. Length of stay was of 14.8±10.1 days. Baseline Karnofsky Performance Score (KPS), presurgical KPS, and KPS at discharge were 87.7±14.9, 64.9 ±19.8 and 76.7±27.2, respectively. A complete recovery was observed in 62.9% of patients. Mortality rate during hospitalization was 7.4%. CONCLUSIONS The knowledge of clinical and surgical factors which might impact on the clinical outcomes could help to better manage patients with CSDH, which represents a surgically "simple" but, indeed, not trivial disease.

Abstract
BACKGROUND Chronic subdural hematoma (CSDH) is sometimes refractory, and this is troublesome for neurosurgeons. Although many studies have reported risk factors or treatments in efforts to prevent recurrence, those have focused on single recurrence, and few cumulative data are available to analyze refractory CSDH. METHODS We defined refractory CSDH as ≥2 recurrences, then analyzed and compared clinical factors between patients with single recurrence and those with refractory CSDH in a cohort study, to clarify whether patients with refractory CSDH experience different or more risk factors than patients with single recurrence, and whether burr-hole irrigation with closed-system drainage reduces refractory CSDH. RESULTS Seventy-five patients had at least 1 recurrence, with single recurrence in 62 patients and ≥2 recurrences in 13 patients. In comparing clinical characteristics, patients with refractory CSDH were significantly younger (P = 0.04) and showed shorter interval to first recurrence (P < 0.001). Organized CSDH was also significantly associated with refractory CSDH (P = 0.02). Multivariate logistic regression analysis identified first recurrence interval <1 month (odds ratio, 6.66, P < 0.001) and age <71 years (odds ratio, 4.16, P < 0.001) as independent risk factors for refractory CSDH. On the other hand, burr-hole irrigation with closed-system drainage did not reduce refractory CSDH. CONCLUSIONS When patients with risk factors for refractory CSDH experience recurrence, alternative surgical procedures may be considered as the second surgery, because burr-hole irrigation with closed-system drainage did not reduce refractory CSDH in our study.

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

Abstract
Chronic subdural hematomas (CSDHs) occur often in elderly persons and can occur with mild head trauma. With burr-hole irrigation as standard treatment, symptoms usually improve and can be cured, and outcomes are good, but postoperative recurrences are a common problem. This study investigated the effectiveness and recurrence rates when using artificial cerebrospinal fluid (ACF) instead of normal saline (NS) as an irrigation solution for burr-hole irrigation in patients with CSDH. This prospective study included 234 consecutive patients who underwent initial surgical treatment by burr-hole irrigation for a CSDH between April 2008 and June 2015. The irrigation solution used was changed from NS to ACF in June 2011. Factors examined with regard to recurrence included age, sex, unilateral or bilateral surgery, computed tomography (CT) findings, antiplatelet or anticoagulant drug use, past history, and irrigation solution (NS or ACF). These were analyzed by univariate and multivariate analyses. Univariate analyses (chi-square test) with a significance level <5% showed that recurrence rates were significantly lower in the ACF group than in the NS group (P = 0.003). Multivariate analysis (multiple logistic regression analysis) showed that the risk of recurrence was reduced 3.14-fold in the ACF group compared to the NS group (odds ratio, 3.143; 95% confidence interval, 0.1504–0.6733; P = 0.0028). None of the other factors were significantly different. In burr-hole irrigation for CSDH, the use of ACF instead of NS as an irrigation solution significantly reduces recurrence rates.

Abstract
OBJECTIVE Chronic subdural hematoma (CSDH), a common condition in elderly patients, presents a therapeutic challenge with recurrence rates of 33%. We aimed to identify specific prognostic factors for recurrence using quantitative analysis of hematoma volume and density. METHODS We retrospectively reviewed radiographic and clinical data of 227 CSDHs in 195 consecutive patients who underwent evacuation of the hematoma through a single burr hole, 2 burr holes, or a mini-craniotomy. To examine the relationship between hematoma recurrence and various clinical, radiologic, and surgical factors, we used quantitative image-based analysis to measure the hematoma and trapped air volumes and the hematoma densities. RESULTS Recurrence of CSDH occurred in 35 patients (17.9%). Multivariate logistic regression analysis revealed that the percentage of hematoma drained and postoperative CSDH density were independent risk factors for recurrence. All 3 evacuation methods were equally effective in draining the hematoma (71.7% vs. 73.7% vs. 71.9%) without observable differences in postoperative air volume captured in the subdural space. CONCLUSIONS Quantitative image analysis provided evidence that percentage of hematoma drained and postoperative CSDH density are independent prognostic factors for subdural hematoma recurrence.

Abstract
Background: Repeat burr hole irrigation and drainage has been effective in most cases of recurrent chronic subdural hematoma (CSDH), however, refractory cases require further procedures or other interventions. Case Description: An 85-year-old male presented with left CSDH, which recurred five times. The hematoma was irrigated and drained through a left frontal burr hole during the first to third surgery and through a left parietal burr hole during the fourth and fifth surgery. The hematoma had no septation and was well-evacuated during each surgery. Antiplatelet therapy for preventing ischemic heart disease was stopped after the second surgery, the hematoma cavity was irrigated with artificial cerebrospinal fluid at the third surgery, and the direction of the drainage tube was changed to reduce the postoperative subdural air collection at the fourth surgery. However, none of these interventions was effective. He was successfully treated by fibrin glue injection into the hematoma cavity after the fifth surgery. Conclusion: This procedure may be effective for refractory CSDH in elderly patients.

Abstract
Compared with burr hole craniostomy (BHC), twist drill craniostomy (TDC) is increasingly popular because of its minimal invasiveness in evacuating chronic subdural hematoma (CSDH). However, the TDC technique varies and is continually developing; moreover, no consensus yet exists regarding the optimal protocol, and the efficacy and safety of TDC is still controversial, especially with respect to a specific method. This article introduces a new modified TDC technique using a novel device, the YL-1 puncture needle, and evaluates its efficacy and advantages compared with BHC.A retrospective study involving 121 patients with CSDH who underwent surgery at a single center was conducted, involving 68 patients undergoing modified TDC (TDC group) and 53 patients treated by BHC (BHC group). The neurological outcome was studied to evaluate the surgery efficacy, and the radiological outcome was assessed as a supplement to the surgery efficacy. In addition, complications, recurrence, and reoperation, as well as pneumocrania, operation duration, and length of stay, were studied to evaluate the advantages of the modified TDC compared with BHC. Independent sample t tests or rank-sum tests were used to compare the outcomes between the 2 groups.The neurological and radiological outcomes did not differ significantly between the TDC and BHC groups (P = 0.852 and P = 0.232, respectively), while the rates of complication and pneumocrania in patients who underwent the modified TDC were significantly lower than that in those who underwent BHC (P = 0.021 and P < 0.001, respectively). The recurrence and reoperation rates in patients from the 2 groups were similar (P = 0.566 and P = 0.715, respectively). The operation duration and length of hospital stay of the patients who underwent the modified TDC were significantly shorter than those of the patients who underwent BHC (both P < 0.001).Modified TDC with a YL-1 puncture needle is a minimally invasive surgical technique to treat CSDH; this procedure is as effective as BHC, but safer and simpler than BHC, and should be considered for patients with CSDH, especially the elderly.
