Abstract
Objective: Chronic subdural hematoma is one of the most common clinical entities encountered in daily neurosurgical practice. Considerable recurrence rates have been reported for chronic subdural hematoma following surgical evacuation. Many studies have suggested various radiological factors that may be associated with the recurrence of CSDH. However, the results are inconsistent. This study focuses on determining the radiological factors predictive of chronic subdural hematoma recurrence. Methods: A retrospective analysis of 113 patients diagnosed with chronic subdural hematoma who were surgically treated between August 2013 and December 2014 was performed. The radiological features were analyzed to clarify the correlation between these radiological factors and postoperative recurrence of chronic subdural hematoma. Results: Twenty patients (17.7%) experienced recurrence. Chronic subdural hematoma recurrence was found to be significantly associated (p<0.05) with preoperative hematoma thickness ≥ 20 mm. Midline shift, hematoma density and bilaterality were not significantly associated with recurrence. Post operative drainage also significantly (p<0.05) reduced chronic subdural hematoma recurrence. Conclusion: Preoperative hematoma thickness ≥ 20 mm is an independent predictor of recurrence of chronic subdural hematoma. Postoperative drainage also significantly reduces chronic subdural hematoma recurrence.

Abstract
Background: Burr-hole irrigation surgery is now recognized as a widespread simple technique for the treatment of chronic subdural hematoma (CSDH). However, recurrence of CSDH is sometimes experienced after initial surgery. Recently, it has been reported that goreisan is effective in preventing CSDH recurrence. Materials and Methods: Methods: We studied patients with CSDH who received burr-hole irrigation at our hospital between January 2011 and December 2014. We divided these patients into three groups. The first group was given goreisan during the early phase after burr-hole irrigation. The second group was given goreisan when there was a visual tendency of recurrence, as observed in the course of computed tomography imaging for outpatients. The third group was not given any drug. Results: The recurrence rate was compared between each group. The recurrence rate was significantly lower in the early goreisan administration group (5% vs. 12%, P = 0.046). There was a decreased tendency of recurrence in the goreisan-administered group compared with the group that was not administered any drug, but this was not statistically different (6.1% vs. 12%, P = 0.082). The recurrence period in the goreisan-administered group was longer than that in the group that was not administered any drug (39.9 ± 12.1 vs. 27.45 ± 8.5, P = 0.017). Conclusions: Goreisan is effective in preventing recurrence of CSDH after burr-hole irrigation.

Abstract
Chronic subdural hematoma (CSDH) is a relatively common condition encountered in a neurosurgical practice. There have been increased efforts in creating different treatment regimens for CSDH to improve patients' outcomes, including the addition of tissue plasminogen activator (tPA) in drains to reduce recurrences. Here, we present the first case report of the safe use of tPA in conjunction with an Integra Camino bolt for maximized drainage of CSDH with a successful neurological recovery and the complete resolution of the hematoma.

Abstract
Surgery is the standard treatment for chronic subdural hematoma (CSDH), one of the common problems in neurosurgical practice. Although medical treatment was used by some authors and found some positive results, it is not accepted by many authors. The aim of this review is to give overall view of the medical management of CSDH. Action of various drugs in the pathophysiological cascade of formation of CSDH was depicted. The review of literature is done under three headings – the primary medical treatment of CSDH, adjuvant medical treatment with surgery, and the treatment of the recurrence. Various classifications of CSDH and the factors influencing the outcome of medical treatment are discussed. There is a role of medical treatment in a selected group of patients with CSDH. Well-designed, multicenter, randomized controlled trials are required to define the indications and standard protocols for the medical treatment of CSDH.

Abstract
BACKGROUND Chronic subdural hematoma (CSDH) is a common entity in neurosurgical practice. However, as a result of the high rate in recurrence, morbidity, and mortality for surgical management, conservative management of CSDH is emerging as a new treatment strategy. Head trauma is a known risk factor of CSDH and plays as an initiator in the genesis of CSDH. We hypothesized that physical activity might also play an important role in the progression of an asymptomatic CSDH. METHODS A prospective pilot study aiming to evaluate the efficacy of reinforced restriction of physical activity for the management of asymptomatic or mild symptomatic CSDH was conducted. Twenty-six patients were enrolled in this study. RESULTS All 26 patients experienced complete resolution of the CSDH ranging from 32 to 182 days (73.1 ± 19.6 days) since the initiation of reinforced restriction of physical activity. Ages ranged from 43 to 84 years old (64.4 ± 9.6 years). No patient experienced recurrence of CSDH during the follow-up. CONCLUSIONS According to our study, physical activity might play a role in the progression of CSDH. Further prospective randomized controlled study is warranted in stable patients without evident intracranial hypertension and impending cerebral herniation.

Abstract
BACKGROUND The exact location of a hematoma in relation to the pachymeninges contributes to typical radiographic presentations. However, because of the complexity of hematoma evolution and neomembrane formation, an unexpected intraoperative finding can lead to a change of surgical strategy. In addition, the concentration of hemoglobin and its degradation products, the integrity of red blood cells, and the infiltration of fibroblasts, polymorphonuclear neutrophils, and macrophages are factors that affect the imaging characteristics on computed tomography and magnetic resonance imaging as the hematoma ages. CASE DESCRIPTION An interdural hematoma (IDH)-a hemorrhage that splits the periosteal dura mater from the meningeal dura mater-is an extremely rare occurrence, and the diagnosis requires confirmation by surgical or pathologic findings. By presenting a case of an IDH that was misdiagnosed as a chronic subdural hematoma before surgery, and reviewing the literature, we propose the radiologic characteristics of presenting both dural border sign and dural beak sign on magnetic resonance imaging as a specific indicator for IDH preoperatively. CONCLUSIONS A careful evaluation of cerebral expansion before membranectomy was mandatory intraoperatively. For IDH, wide inner membranectomy (i.e., excision of meningeal dura mater) should not be necessary. An IDH should be considered as a distinct disease category when evaluating an extra-axial hematoma despite its rarity, because the characters of radiologic, histopathologic findings are different. In addition, surgical strategy varies for epidural or subdural hematoma in different hematoma stages.

Abstract
The aim of this work was comparison of two algorithms of perfusion computed tomography (PCT) data analysis for evaluation of cerebral microcirculation in the perifocal zone of chronic subdural hematoma (CSDH). Twenty patients with CSDH after polytrauma were included in the study. The same PCT data were assessed quantitatively in cortical brain region beneath the CSDH (zone 1), and in the corresponding contralateral brain hemisphere (zone 2) without and with the use of perfusion calculation mode excluding vascular pixel 'Remote Vessels' (RV); 1st and 2nd analysis method, respectively. Comparison with normal values for perfusion indices in the zone 1 in the 1st analysis method showed a significant (p < 0.01) increase in CBV and CBF, and no significant increase in MTT and TTP. Use of the RV mode (2nd analysis method) showed no statistically reliable change of perfusion parameters in the microcirculatory blood flow of the 2nd zone. Maintenance of microcirculatory blood flow perfusion reflects the preservation of cerebral blood flow autoregulation in patients with CSDH.

Role of antithrombotic therapy in the risk of hematoma recurrence and thromboembolism after chronic subdural hematoma evacuation: a population-based consecutive cohort study. Acta Neurochir (Wien) 2017; 159:2045-2052.

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

Abstract
Chronic subdural hematoma (CSDH) can be easily treated by burr hole surgery. However, several complications including intracerebral hemorrhage (ICH), subarachnoid hemorrhage (SAH), and acute subdural hematoma are rare after evacuation of a CSDH. A 77-year-old man was admitted with right hemiparesis and dysarthria. A brain computed tomography (CT) scan revealed a bilateral CSDH with midline shifting toward the right side. The patient got the burr hole trephination with the catheters insertion in the both sides of parietal area under the local anesthesia. After burr hole surgery immediately, he developed left side weakness and decreased level of consciousness. Repeat CT scans detected a diffuse SAH and multiple small ICHs. He was treated conservatively and fully recovered at discharge after 1 month. To avoid these complications, slow and gradual drainage of the CSDH is needed. The authors report a rare case of SAH and multipunctate ICHs in both cerebral hemispheres after evacuation of a bilateral CSDH.

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

Abstract
Chronic subdural hematoma (CSDH) and symptomatic subdural hygroma are common diseases that require neurosurgical management. Burr hole trephination is the most popular surgical treatment for CSDH and subdural hygroma because of a low recurrence rate and low morbidity compared with craniotomy with membranectomy, and twist-drill craniotomy. Many reports suggest that placing a catheter in the subdural space for drainage can further reduce the rate of recurrence; however, complications associated with this type of drainage include acute subdural hematoma, cortical injury, and infection. Remote hemorrhage due to overdrainage of cerebrospinal fluid (CSF) is another possible complication of burr hole trephination with catheter drainage that has rarely been reported. Here, we present 2 cases of remote hemorrhages following burr hole trephination with catheter drainage for the treatment of CSDH and symptomatic subdural hygroma. One patient developed intracerebral hemorrhage and subarachnoid hemorrhage in the contralateral hemisphere, while another patient developed remote hemorrhage 3 days after the procedure due to the sudden drainage of a large amount of subdural fluid over a 24-hour period. These findings suggest that catheter drainage should be carefully monitored to avoid overdrainage of CSF after burr hole trephination.

Abstract
BACKGROUND Burr hole craniostomy is a widely used method for the evacuation of CSDH. However it is not clear whether the irrigation during operation improves the prognosis or gives rise to additional complications instead. This retrospective cohort study was conducted to determine this issue. METHODS Patients attending two medical centers in China who underwent burr hole drainage with irrigation (BHDI) or burr hole drainage without irrigation (BHD) for unilateral CSDH during January 2013 to December 2016 were included in this study. The patients' clinical information and follow-up data were retrospectively reviewed, and the radiologic findings were processed using the 3D Slicer software. The differences in outcomes were identified using t-test, chi-square test, or Fisher's exact test. RESULTS A total of 151 patients comprising 63 patients in the BHD group and 88 patients in the BHDI group were included. Patients in the BHDI group had a higher volume of pneumocrania on the first postoperative day than that of patients in the BHD group (p < 0.05). No significant differences were observed between the two approaches in rates of rebleeding, recurrence and other complications (p > 0.05). CONCLUSIONS Irrigation had no improvement in the long-term curative effect on CSDH, but it increased the risk of short-term complication in terms of pneumocrania. Therefore, this study suggests that irrigation is not an obligatory procedure during burr hole drainage.

Abstract
A vast amount of literature has been published investigating the factors associated to the recurrence of a chronic subdural hematoma (SDH). However, little exists in the literature about the best medical management of the residual SDH in order to prevent the recurrence. Moreover only few studies quantitatively assess clinical and radiological outcomes of residual post-operative SDH. In this study, to our knowledge, we report the first series of chronic SDH with a quantitative outcomes analysis of the effects of fluid therapy on residual post-operative SDH. Moreover we discuss the pertinent literature. We reviewed clinical and outcome data of 39 patients (44 SDH; 12 F, 27 M) submitted to a burr-hole evacuation of a SDH. The mean age was 76.97±7.77years. All patients had a minimum 3-month follow-up (FU). Post-operatively, an intravenous saline solution was started in all cases (2000ml in 24h) and administered for 3days. Then an oral hydration with 2l per day of water was started and continued as outpatients. Glasgow Coma Scale (GCS), Karnofsky Performance Status (KPS), SDH volume and midline shift were evaluated pre-operatively, post-operatively and at FU. We found a statistically significant improvement of post-operative and at FU GCS and KPS compared to the pre-operative. SDH volume and midline shift were also statistically significant reduced in the post-operative and at FU. No complication occurred. Only 1 patient required a reoperation at 3months FU for neurological worsening. Oral fluid therapy is a safe and effective treatment for residual SDH.

Abstract
Despite extensive investigations, the process of development of chronic subdural hematoma (CSDH) is not known. The present study aims to investigate CSDH by measuring biomarkers in it, gas analysis, and immunohistochemical examination. A total of 42 patients with symptomatic CSDH who underwent burr-hole drainage were enrolled. Intraoperatively, hematoma fluid and peripheral venous blood (PVCSDH) were simultaneously collected. As controls, peripheral venous blood (PVControl) and intracranial cerebrospinal fluid (CSF) were collected from other subjects during other surgeries. CatK, lipocalin-type prostaglandin D synthase (PGDS), and cystatin C (CysC) present in these specimens were measured using enzyme-linked immunosorbent assay. Data obtained were statistically analyzed after age correction. In 15 patients, gas analysis was performed for CSDH and PVCSDH. Furthermore, immunohistochemical examination for the outer membrane was performed for four patients. CatK, PGDS, and CysC levels were markedly elevated in the CSF and CSDH. CatK levels in PVCSDH were significantly higher than in PVControl (P<0.0001). In contrast, CysC levels in PVCSDH were significantly lower than in PVControl (P=0.004). The gas analysis revealed that the internal environment of CSDH is characterized by marked hypoxia, hypoglycemia, and lactic acidosis. Furthermore, the outer membrane consistently showed a diffuse staining for CatK. Based on these, CatK was thought to play a role in the development of CSDH, with the levels in peripheral venous blood elevated in patients with CSDH.

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
Headache is a major symptom in chronic subdural hematoma (CSDH) patients. However, some CSDH patients do not complain headache although the hematoma is thick with definite midline shift. This clinical study was performed to identify the mechanism of headache in CSDH patients. We compiled clinical data of 1080 surgically treated CSDH patients (711 males and 369 females), and in 54 cases, the pressure of hematoma was measured during burr hole surgery using a glass-stick manometer. Headache was recognized in 22.6% of patients, while nausea or vomit suggesting increased intracranial pressure was detected in only 3.0%. Ophthalmological examination was performed in 238 patients, and papilledema was identified in only one patient (0.4%). The mean age of patients with headache (59.8 ± 16.9 years) was significantly younger than that of those without (75.7 ± 11.2 years) (P < 0.01). In 54 cases, the mean hematoma pressure was not significantly different between patients with (17.1 ± 6.2 mmH2O) and without (18.4 ± 7.2 mmH2O) headache (P > 0.10). Hematoma thickness was significantly greater in patients without headache (P < 0.01), but the ratio of midline shift to hematoma thickness was significantly greater in patients with headache (P < 0.01). In our results, the status of increased intracranial pressure was rare in CSDH patients, and high hematoma pressure was not a cause of headache. Midline shift was the most influenced factor for headache in our study, and based on the results, the authors consider that the potential cause of headache in CSDH might be stretching or twisting of the pain-sensitive meninges and meningeal arteries or veins.

Subdural effusion protects the aging brain from harmful ventriculomegaly. Med Hypotheses 2017; 108:108-114. [PMID: 29055382 DOI: 10.1016/j.mehy.2017.08.004] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2017] [Revised: 06/17/2017] [Accepted: 08/06/2017] [Indexed: 11/21/2022]
Abstract
The human brain loses its volume and its function during aging. The solid part of the brain within the intracranial space, the brain parenchyma, decreases in volume with age; while the cerebrospinal fluid (CSF) volume increases. With progressive loss of brain parenchymal volume (BPV), CSF may shift from cerebral ventricles to the subdural space, forming subdural effusion (SDE), whose role in the brain aging process remains unclear. We hypothesize that damages associated with ventriculomegaly can be lessened after formation of SDE. As the BPV decreases, the enlarged ventricular surface area causes dysfunction of its lining ependymal cells, followed by damages to the periventricular tissue. The periventricular nerve fibers are stretched by the enlarged ventricles. We hypothesize that after the formation of SDE, ventriculomegaly can be stopped or even reversed. By allowing the atrophic brain to reside in a smaller fraction of the intracranial volume, damages associated with ventriculomegaly can be alleviated. If our hypothesis is correct, physicians should continue to maintain a conservative approach for uncomplicated SDE. For focal or global brain parenchymal loss caused by various pathologies, intracranial spacers can be employed to simulate the effect of SDE to protect the brain. For treatment of idiopathic normal pressure hydrocephalus, aggressive ventricular size reduction should be pursued. Finally, the protective effects of SDE have its limits. Extremely enlarged subdural volume can cause acute or chronic subdural hematoma, further damaging the brain.

Predictors of Recurrence and Complications After Chronic Subdural Hematoma Surgery: A Population-Based Study. World Neurosurg 2017; 106:609-614. [PMID: 28735129 DOI: 10.1016/j.wneu.2017.07.044] [Citation(s) in RCA: 57] [Impact Index Per Article: 8.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2017] [Revised: 07/09/2017] [Accepted: 07/11/2017] [Indexed: 11/23/2022]
Abstract
OBJECTIVE To investigate predictors of recurrence and moderate to severe complications after burr-hole surgery for chronic subdural hematoma (cSDH). METHODS A retrospective review was conducted in a Scandinavian single-center population-based cohort of 759 adult patients with cSDH operated with burr-hole surgery between January 1, 2005 and December 31, 2010. Possible predictors of recurrence and complications, assessed using a standardized reporting system of adverse events, were identified and analyzed in univariable analyses. Variables with a P value < 0.10 were included in a multivariable regression model. RESULTS Recurrence was observed in 85 patients (11.2%), whereas moderate to severe complications were observed in 35 patients (4.6%). Bilateral hematoma (odds ratio [OR], 2.05; 95% confidence interval [CI], 1.25-3.35; P < 0.01) and largest hematoma diameter in millimeters (OR, 1.05; 95% CI, 1.01-1.09; P < 0.01) were independent predictors of recurrence in the multivariable model analysis. Glasgow Coma Scale (GCS) score of <13 (OR, 6.06; 95% CI, 2.72-13.51; P < 0.01) and Charlson Comorbidity Index (CCI) >1 (OR, 2.28; 95% CI, 1.10-4.75; P = 0.03) were independent predictors of moderate to severe complications. CONCLUSIONS Recurrence after cSDH surgery is more often encountered in patients with radiologically more extensive disease reflected by bilateral hematoma and large hematoma diameter. On the other hand, moderate to severe complications are more often seen in patients in a worse clinical condition, reflected by decreased level of consciousness and more comorbidities.

Mini-Craniotomy Under Local Anesthesia for Chronic Subdural Hematoma: An Effective Choice for Elderly Patients and for Patients in a Resource-Strained Environment. World Neurosurg 2017; 106:676-679. [PMID: 28735131 DOI: 10.1016/j.wneu.2017.07.057] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2017] [Revised: 07/09/2017] [Accepted: 07/11/2017] [Indexed: 11/20/2022]
Abstract
BACKGROUND Mini-craniotomy for chronic subdural hematoma (CSDH) is associated with lower rates of recurrence. However, the procedure is performed mostly with the patient under general anesthesia (GA) and therefore frequently requires an intensive care unit (ICU) facility, especially in the elderly population. Because of the unavailability of ICU beds, and to avoid GA, we started to perform this procedure with the patient under local anesthesia (LA). MATERIALS AND METHODS This was a retrospective medical chart review conducted in the section of Neurosurgery at the Aga Khan Hospital in Karachi, Pakistan. The study duration was 1 year. We included patients aged 55 years or older undergoing surgery for CSDH. Clinical characteristics, hospital stay, and recurrence rates were compared between 2 groups, local versus general anesthesia. RESULTS Thirty-five patients underwent mini-craniotomy for CSDH in the study period. Sixteen patients underwent mini-craniotomy under LA versus 19 patients for GA. Median age for the LA group was 67 years compared with 70 years in the GA group. Four patients from the LA group experienced postoperative complications versus 7 from the GA group. Only one patient in the LA group required an ICU bed in the postoperative period. There was no recurrence in LA group. The overall recurrence was 2.86%. CONCLUSIONS Mini-craniotomy for CSDH under LA is an equally effective procedure compared with mini-craniotomy under GA. In addition, it minimizes the risks of GA in the elderly population and obviates the need of a postoperative ICU bed. It also reduces operative time and hospital stay as compared with GA.

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
PURPOSE To evaluate the frequency of emergency diseases that were detected unexpectedly using FDG-PET/CT. MATERIALS AND METHODS Interpretation reports for 11,663 FDG-PET/CT studies in our hospital were retrospectively reviewed. Patients with major emergency diseases were extracted according to the following exclusion criteria: (1) relevant findings had been recognized prior to the PET/CT; (2) an intervention or operation that may have been relevant to the present findings was performed within 1 month prior to the PET/CT; and (3) the clinical course could not be investigated sufficiently (e.g., in cases where the patients were introduced from other hospitals). RESULTS Forty-one patients (0.35%) with unexpected emergency diseases were identified. The most frequent disease was pneumothorax (8 patients), followed by chronic subdural hematoma (CSH) (7 patients), ureteral stone (7 patients), and abdominal aortic aneurysm (AAA) with a dirty fat sign or a high-attenuation crescent sign visualized on CT (4 patients). Nine patients (2 pneumothorax, 3 CSH, 1 cerebral hemorrhage, 1 acute cholecystitis, 1 acute pancreatitis, and 1 acute appendicitis) were hospitalized and/or underwent therapeutic intervention within 1 week after the PET/CT. CONCLUSION Although rare, an unexpected emergency disease requiring urgent management can be detected using FDG-PET/CT in oncology patients.

Abstract
BACKGROUND Chronic subdural hematoma (CSDH) is a common neurological pathology, especially in older patients. The actual "gold standard" of treatment is surgical evacuation, with various techniques used across neurosurgical teams. Over the years, there has been growing evidence that inflammatory processes play a major role in the pathogenesis of CSDH. In that context, the use of corticosteroids has been proposed alone or as an adjuvant treatment to surgery. However, this practice remains very empirical and there is a need for high-quality-of-evidence studies to clarify the role of corticosteroids in the management of CSDH. METHODS/DESIGN We propose a double-blind, randomized controlled trial comparing methylprednisolone versus placebo in the treatment of CSDH without clinical and/or radiological signs of severity. The treatment will be administered daily for a duration of 3 weeks, at a dose of 1 mg/kg. The primary endpoint will be the delay of occurrence of surgical treatment at 1 month following the introduction of the treatment. Secondary endpoints will include the rate of recourse to surgery, survival rate, quality of life and functional assessments, occurrence of systemic secondary effects and radiological assessment of the response to treatment. This multimodal assessment will be done at 1, 3 and 6 months. Two hundred and two patients (101 per arm) are expected to be included considering our primary hypotheses. DISCUSSION This trial started in June 2016; its results may open interesting alternatives to surgery in the management of patients harboring a CSDH, and may provide insights into the natural history of this common pathology.

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

Abstract
Objective: To investigate the clinical characteristics, pathogenesis and surgical strategy for the chronic subdural hematoma associated with arachnoid cyst (AC). Method: Ten patients of chronic subdural hematoma associated with AC were retrospectively enrolled from the Neurosurgery Department of Tianjin Medical University General Hospital from January 2012 to September 2015, with a mean age of 27.5±5.6 years (range, 18-37 years). All patients simply performed a burr hole drainage of hematoma and left the AC intact, then followed up for 12 to 18 months after discharge respectively. Results: In this study, the AC in 8 of 10 cases occurs in the middle cranial fossa, and the other 2 cases root in the cerebral hemisphere.The AC of 10 patients all locate near the hematoma cavity.Nine patients had a full recovery, and only one patient had a recurrent subdural hematoma with a secondary operation, then recovery in 3 months postoperation.All patients lived completely free of neurological symptom and showed no recurrence in the follow-up period with a Barthel index more than 90. Conclusion: Simply burr hole drainage of hematoma and leave intact AC achieves satisfied outcome and provides a reliable therapy strategy for chronic subdural hematoma associated with arachnoid cyst.

Kim JH, Kim CH, Lee CY. Efficacy of Arachnoid-Plasty on Chronic Subdural Hematoma Following Surgical Clipping of Unruptured Intracranial Aneurysms. World Neurosurg 2017; 104:303-310. [PMID: 28479524 DOI: 10.1016/j.wneu.2017.04.162] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2017] [Revised: 04/25/2017] [Accepted: 04/26/2017] [Indexed: 10/19/2022]
Abstract
BACKGROUND We aimed to elucidate the effects of arachnoid plasty (ARP) on chronic subdural hematoma (CSDH) occurrence following clipping surgery. METHODS In total 217 patients (ARP, n = 97; non-ARP, n = 120) who had undergone unruptured intracranial aneurysm (UIA) surgical clipping via the pterional approach were retrospectively assessed. Predisposing factors for CSDH development following the surgery were investigated. Thickness and volume of the subdural fluid collection (SDFC) were measured to determine whether ARP affects postoperative SDFC. RESULTS The occurrence of postoperative CSDH was higher in patients without ARP compared to those with ARP (12.5 vs. 3.1%; P = 0.01). In multivariate analyses, having an SDFC volume ≥15 mL on postoperative day (POD) 8, (odds ratio [OR] = 15.113; range = 3.159-72.290), and male sex (OR = 4.274; range = 1.291-14.148) were identified as independent predictive factors. Having had ARP (OR = 0.228; range = 0.056-0.927) was, as an independent variable, negatively correlated with the occurrence of CSDH (P < 0.05). Moreover, SDFC volume ≥15 ml on POD 8 was significantly less common in the ARP group compared with the non-ARP group (P = 0.03). CONCLUSION Patients who underwent ARPs developed fewer CSDHs following UIA clipping surgery. The factors that predicted the development of CSDH included male sex, SDFC volume on POD 8, and ARP. In addition, the ARP patients had lower SDFC volumes (<15 mL). These findings suggested that ARP reduced the incidence of CSDHs after surgical clippings in patients with unruptured aneurysms.
