Background: A chronic subdural hematoma (CSDH) is one of the most common neurosurgery operations. This study aimed to evaluate the effect of topical corticosteroids combined with surgery in patients with CSDH. Materials and Methods: The present study is a clinical trial study on patients referred to hospitals associated with Ahvaz University of Medical Sciences with chronic subdural hematoma in 2019. Patients requiring surgical drainage of chronic subdural hematoma who met the inclusion criteria underwent open craniotomy surgery on the side of the hematoma. A drain was placed in the open craniotomy site. On the third day after the operation, before removing the drain, 40 mg of methylprednisolone sodium succinate was injected through the drain into the subdural space, after which the drain was pulled entirely. Patients were evaluated with the Markwalder Grading Scale (MGS) on the third day, third month, and sixth month after surgery for improved or worsened neurological symptoms. Also, in the third and sixth months after surgery, the patients underwent Computerized Tomography Scan imaging and were checked for recurrence. Results: 32 patients with CSDH entered the study, including 28 men and four women, with a mean age of 71.62 ± 9.85 years. Moreover, 87.5 % had a unilateral chronic subdural hematoma (uCSDH), and 12.5 % had a bilateral chronic subdural hematoma (bCSDH). Left and right uCSDHs had the same frequency (43. 8 %). After surgery, 26 patients had no postoperative complications, and six patients experienced pneumocephalus. Conclusion: Topical dexamethasone injection through the potential CSDH cavity can result in desirable outcomes.

Along with medulloblastomas, Atypical teratoid/rhabdoid tumors (ATRT) are embryonic in origin and histologically show rhabdoid cells and mixed portions of neuroectodermal, ectodermal, and mesenchymal cells. ATRTs are present according to the location of the tumor within the CNS. Signs of headache, vomiting, gait abnormalities, and instability are typical of cerebellar tumors. There is no clear treatment protocol for ATRTs. In this report, we present the case of a 1-year-old boy who was diagnosed with a supratentorial ATRT. The patient underwent surgery and was referred for adjuvant chemo/radiotherapy.

Objective: Chronic subdural hematoma (CSDH) is typically seen in elderly people with unilateral hemorrhages. The aim of this study was to examine the clinical outcomes of patients under the age of 50 who were treated at our clinic for bilateral CSDHs. Material and Method: This retrospective study included 20 patients under the age of 50 who had been diagnosed with bilateral CSDHs and treated with burr-hole drainage between 2000 and 2022 at Istanbul Faculty of Medicine, Department of Neurosurgery, Istanbul University. The patients’ demographic information, clinical data, and radiological images were obtained retrospectively from the hospital system. The data were subjected to descriptive statistical analysis using the IBM SPSS statistics 28.0.0 program. Result: There were 14 (70%) males and 6 (30%) females in our study, with a mean age of 20.5 years. The most common complaints among the patients were headaches in nine patients (45%), newly developed paresis in five patients (25%), and seizures in four patients (20%). It was discovered that 17 patients (85%) had no history of head trauma. CSDH was evacuated by bilateral burr-holes in 14 patients (70%). Three (21.4%) of 14 patients with bilateral burr-holes, and 3 (50%) of the remaining six patients were reoperated due to recurrent bleeding in the follow-up period. Conclusion: In our study, trauma history and use of antiaggregants and anticoagulants were low. More comprehensive studies on the etiology of bilateral CSDH in patients under 50 years of age are required. [ABSTRACT FROM AUTHOR]

Background: Trigeminal neuralgia, a common condition in clinical practice, often occurs due to vascular compression caused by aberrant or ectopic arterial or venous vessels. Microvascular decompression through a minimally invasive retrosigmoidal approach has shown high rates of pain control, low complication rates, and excellent therapeutic results. Objective: To describe the surgical technique and clinical outcomes in terms of pain relief after microvascular decompression of the trigeminal nerve through a minimally invasive retrosigmoidal parasterional burr-hole technique. Methods: A group of patients with trigeminal neuralgia refractory to medical management who underwent microvascular decompression were examined. The records of the patients were considered retrospectively (2016–2018), and the outcomes were considered based on the Visual Analogue Scale (VAS) and the Barrow Neurological Institute Pain Scale (BNIPS) added to a technical note of the surgical technique for a minimally invasive retrosigmoidal parasterional burr-hole. Results: Twenty-two patients were evaluated, and clinical assessment after surgical intervention showed a decrease in pain according to the VAS, resulting from an average preoperative state of 9.5 ± 0.37 to a postoperative condition of 1.32 ± 1.28, exhibiting statistically significant changes (p < 0.0001, d = 9.356). On the other hand, in relation to the BNIPS scale, a decrease from an average preoperative status of 4.55 ± 0.25 to a postoperative status at 12 months of 1.73 ± 0.54 was also demonstrated, showing significant changes (p < 0.0001, d = 3.960). Conclusion: Microvascular decompression of the trigeminal nerve through a minimally invasive retrosigmoidal parasterional burr-hole is feasible and can be a safe and effective technique for the management of pain. However, further research employing larger sample sizes and longer follow-up periods is necessary. [ABSTRACT FROM AUTHOR]

Highlights • The ABC/2 method is an accurate and simple “bedside” technique to estimate pneumocephalus volume. • The postoperative pneumocephalus volume after bilateral burr-hole drainage was significantly larger than that of unilateral burr-hole drainage (29.34 ml versus 12.21 ml, p < 0.001). • The estimated volumes of pneumocephalus by the formula ABC/2 were significantly correlated to the volumes as measured by the computer-assisted volumetric technique, with r = 0.992 (p < 0.001).

Background There is an increasing incidence of chronic subdural hematoma due to extended life expectancy and associated trauma and fall risk. This retrospective study evaluates the efficacy of two burr-hole craniotomy over mini-craniotomy. Methods Sixty-five patients were recruited over 2 years, of which 56 were male and 9 were females. A patient with a chronic subdural hematoma either underwent burr-hole craniostomy or mini-craniotomy for hematoma evacuation. Glasgow coma scale (GCS) and modified Rankin score were used to assess the neurological status and interventional outcome at discharge and follow-up, respectively. A head CT scan was performed at 3 week and 3 month follow-up. Statistical Analysis Categorical data are presented as frequency and percentage, while non-categorical data are represented as mean ± SD. Statistical significance for difference in outcome between the two groups was analyzed using the chi-square test and p -value less than 0.05 was considered statistically significant. Results The mean age of patients was 55.6 years. Headache (35 cases), hemiparesis, and altered sensorium were seen in 20 patients, each with the main presenting symptoms. Trauma history was noted in 69.2% of patients. One (3.7%) hematoma recurrence in the burr-hole group and four (8.3%) in the mini-craniotomy group was recorded. The mean operative time was longer in the minicraniotomy group (124.2 min vs. 75.4 min; p < 0.001). A higher incidence of recurrence was noted in the craniotomy group (8.3%) than the burr-hole group (3.7%). No statistical difference in the recurrence rate, duration of hospital stay, GCS at discharge, modified Rankin score between the two study groups at discharge was noted. Conclusion Two burr-hole craniostomy is a safe and effective surgical option to treat chronic subdural hematoma. It is also validated in patients on anticoagulants and antiplatelet medications with adequate pre-surgical correction of coagulation parameters. [ABSTRACT FROM AUTHOR]

Background: Postoperative pneumocephalus is associated with a higher risk of recurrence of chronic subdural hematoma (cSDH). However, there is no verified simple way to measure the pneumocephalus volume at the bedside for daily clinical use. The ABC/2 method was shown to be a simple and reliable technique to estimate volumes of intracranial lesions, such as intracranial hematomas. This study aims to evaluate the accuracy of the ABC/2 formula in estimating volumes of pneumocephalus, as compared to the gold standard with computer-assisted volumetric analysis. Methods: A total of 141 postoperative computed tomographic (CT) brain scans of cSDH patients with burr-hole drainage were analysed. Pneumocephalus volume was measured independently by both the ABC/2 formula and the computer-assisted volumetric measurement. For the computer-assisted measurement, the volume of the air was semiautomatically segmented and calculated by computer software. Linear regression was used to determine the correlation between the ABC/2 method and computer-assisted measurement. Results: The postoperative pneumocephalus volume after bilateral burr-hole drainage was significantly larger than that of unilateral burr-hole drainage (29.34 ml versus 12.21 ml, p < 0.001). The estimated volumes by the formula ABC/2 significantly correlated to the volumes as measured by the computer-assisted volumetric technique, with r = 0.992 (p < 0.001). The Pearson correlation coefficient is very close to 1, which signifies a very strong positive correlation, and it is statistically significant. Conclusions: An excellent correlation is observed between the ABC/2 method and the computer-assisted measurement. This study verified that the ABC/2 method is an accurate and simple "bedside" technique to estimate pneumocephalus volume. Highlights: • The ABC/2 method is an accurate and simple "bedside" technique to estimate pneumocephalus volume. • The postoperative pneumocephalus volume after bilateral burr-hole drainage was significantly larger than that of unilateral burr-hole drainage (29.34 ml versus 12.21 ml, p < 0.001). • The estimated volumes of pneumocephalus by the formula ABC/2 were significantly correlated to the volumes as measured by the computer-assisted volumetric technique, with r = 0.992 (p < 0.001).

Introduction. Chronic subdural haematomas (cSDH) are one of the most common types of traumatic intracranial lesion. Burr--hole craniostomy followed by closed-system drainage has become the treatment of choice. However, there is no definitive indication as to the number of burr-holes needed. Our aim was to to assess clinical and radiological outcomes taking into account the number of burr-holes made. Material and methods. A retrospective single-centre-study was performed including patients treated for cSDH by performing burr-hole craniostomy from 2012 to 2018. After collecting data regarding demographics, comorbidities, and clinical and radiological records, haematomas were grouped depending on the number of burr-holes made (Group 1: single burr-hole; Group 2: double burr-holes). Clinical and radiological outcomes were statistically compared between groups, as well as the main complications. Results. After collecting 171 patients, 205 cSDHs were analysed. 173 were treated with a single burr-hole (we called these Group 1) and 32 with double burr-holes (Group 2). No differences in preoperative characteristics were found between the groups, except for diabetes mellitus and previous antiplatelet/anticoagulation treatment. No radiological differences were found regarding haematoma volume (p = 0.7) or thickness (p = 0.3). Surgical site infection (p = 0.13), recurrence (p = 0.6), acute rebleeding (p = 0.25) and mortality (p = 0.94) were assessed without evidencing statistically significant differences. At the time of hospital discharge, most patients showed a remarkable clinical improvement, regardless of the number of burr-holes made (p = 0.7). Conclusions. This study suggests that cSDH can be efficiently evacuated by a single burr-hole craniostomy, a less invasive and shorter surgical procedure with quite good clinical outcomes and a low rate of complications.
