RESUMO
INTRODUCTION: Bibliometrics, a statistical method assessing the influence of scholarly works, was employed to analyze the evolution of endoscopic surgery for craniosynostosis. METHODS: This comprehensive review followed PRISMA guidelines, sourcing data from PubMed, Embase, and Web of Science, focusing on clinical and surgical outcomes up to December 2023. We identified 1409 records, with 83 papers meeting inclusion criteria. RESULTS: The majority of studies originated from the Americas (79%), predominantly from the United States (75.9%). The typical study design was retrospective cohort studies (62%), involving a total of 8,175 patients with median research duration of 8 years. Citation metrics indicated an average count of 38.9 per paper, with notable contributions from several key authors. A distinct increase in research was observed in recent years, particularly from 2011 onwards, peaking in 2022 and 2023. The top 10 most cited papers, largely emanating from the U.S., had a higher median patient number (103) compared to the overall median (53), suggesting their significant impact. These papers were primarily published in journals with higher impact factors and citation indicators. The most cited research was notably published in the Journal of Neurosurgery-Pediatrics. CONCLUSION: This analysis provides a comprehensive view of the field, highlighting the growing trend and clinical importance of endoscopic approaches in craniosynostosis, offering a valuable resource for future research and clinical practice.
RESUMO
BACKGROUND: Ventriculoatrial shunt (VAS) is an important treatment option for normal pressure hydrocephalus (NPH). However, clinical studies reporting the use of VAS for NPH lack sufficient standardization for meta-analytic comparisons that could provide robust evidence regarding its use. This study aims to assess the quality of reporting in these studies and develop a reporting guideline checklist to standardize terminology, concepts, and reporting while reinforcing the essential elements to ensure comparability and reproducibility. METHODS: This is a systematic literature review that followed the PRISMA guidelines with the search in Medline, Embase, and Web of Science databases, with no timeframe restriction. The level of evidence of the studies was assessed using the GRADE system, and the rigor used in the publication of the results was assessed concerning adherence to the guidelines indicated by the EQUATOR Network Group. Furthermore, the studies were scrutinized focusing on eight domains: (1) Characteristics of the included studies and baseline characteristics of the patients; (2) Reporting methodology; (3) Pivotal concepts definition; (4) Adverse events assessment; (5) Data writing and reporting; (6) Detailed outcomes reporting; (7) Specific clinical outcomes assessment and reporting; and (8) Complications reporting. RESULTS: A total of 14 studies with 734 patients and 753 shunts were included in this review, and the assessment exposes notable deficiencies in reporting, specifically in baseline patient details, methodology, and outcome assessments. Only two studies followed reporting guidelines, prompting concerns about comprehensive reporting of adverse events and intraoperative complications. Varied reporting completeness existed for shunt-related issues. The absence of standardized definitions for key concepts and insufficient intervention details were observed. A VAS-NPH reporting guideline, encompassing 36 items across eight domains, was developed to address these shortcomings. CONCLUSION: This systematic review reveals significant deficiencies in methodological rigor and reporting quality. The proposed VAS-NPH Reporting Guideline covers all essential aspects and is a potential solution to rectify these shortcomings and increase transparency, comparability, and reproducibility. This initiative aims to advance the level of evidence and enhance knowledge regarding the use of VAS in NPH.

BACKGROUND AND OBJECTIVES: Chronic subdural hematoma (CSDH) management involves various surgical techniques, with drainage systems playing a pivotal role. While passive drainage (PD) and active drainage (AD) are both used, their efficacy remains contentious. Some studies favor PD for lower recurrence rates, while others suggest AD superiority. A systematic review and meta-analysis were conducted to address this controversy, aiming to provide clarity on optimal drainage modalities post-CSDH evacuation. METHODS: This systematic review and meta-analysis followed preferred reporting items for systematic reviews guidelines, searching PubMed, Embase, and Web of Science until February 2024. Inclusion criteria focused on studies comparing active vs PD for subdural hematomas. Data extraction involved independent researchers, and statistical analysis was conducted using R software. The assessment of risk of bias was performed using the Risk of Bias in Non-Randomized Studies of Interventions framework and the Risk Of Bias 2 tool. RESULTS: In this meta-analysis, involving 1949 patients with AD and 1346 with PD, no significant differences were observed in recurrence rates between the active (13.6%) and passive (16.4%) drainage groups (risk ratio [RR] = 0.87; 95% CI: 0.58-1.31). Similarly, for complications, infection, hemorrhage, and mortality, no significant disparities were found between the 2 drainage modalities. Complication rates were 7.5% for active and 12.6% for PD (RR = 0.74; 95% CI: 0.36-1.52). Infection rates were available for 635 patients of the active group, counting for 2% and 2.6%, respectively (RR = 0.98; 95% CI: 0.24-4.01). Hemorrhage rates were also available for 635 patients of the active group, counting for 1.1% and 2.2%, respectively (RR = 0.44; 95% CI: 0.11-1.81). Mortality rates were 2.7% and 2.5%, respectively (RR = 0.94; 95% CI: 0.61-1.46). CONCLUSION: Our study found no significant difference between passive and AD for managing complications, recurrence, infection, hemorrhage, or mortality in CSDH cases. Further large-scale randomized trials are needed for clarity.
RESUMO
BACKGROUND: Traditionally, patients undergoing craniotomy were subject to extended hospital stays for intensive monitoring and management of potential complications. However, with the evolution of surgical methods, anesthesia, and postoperative protocols, the feasibility and interest in same-day discharge (SDD) are growing. This study aimed to evaluate whether same-day discharge is a safe and feasible approach in craniotomy through a meta-analysis of the available literature. METHODS: Following PRISMA guidelines, a comprehensive search was conducted across Medline, Embase, Cochrane, and Web of Science databases from inception to December 2023. Eligible studies comprised reports in English with a minimum of 4 patients who underwent craniotomies and were discharged with same-day discharge, whether single-arm or comparative with normal discharge. Single proportion analysis with 95 % confidence interval (CI) was used to pool the studies and Odds Ratio (OR) with 95 % CI was used to measure effects in comparative analysis. A random-effects model was adopted. Endpoints included success and failure of pre-planned same-day discharge, and postoperative complications throughout the hospital stay (until discharge), these complications were further categorized into major and minor complications. Also, need for reoperation, readmission within 24 h, readmission after 24 h, and mortality. RESULTS: Seven observational studies were included. Five studies were included in the single-arm analysis, comprising data from 715 patients. Four studies comprising 731 patients were included in the comparative analysis, of whom 233 were discharged on SDD, and 498 were discharged normally. The analysis revealed a success rate of 88 % (95 % CI, 83 %-94 %), readmission to the hospital within the initial 24 h rate of 2 % (95 % CI, 1 %-2 %), readmission after 24 h rate of 1 % (95 % CI, 0 %-2 %;), total postoperative complications until discharge rate of 2 % (95 % CI, 1 %-4 %), major complications rate of 0 % (95 % CI, 0 %-0 %), minor complications rate of 2 % (95 % CI, 1 %-4 %), and mortality rate of 0 % (95 % CI, 0 %-0 %). Comparative analysis for complications and mortality showed no difference between both approaches. CONCLUSION: This systematic review and meta-analysis identified that same-day discharge in craniotomy for selected patients, as well as for tumor resection craniotomies, is highly feasible and safe, with a high success rate, low failure, and reoperation rates. Moreover, for selected patients, no evidence of harm in same-day discharge was identified when compared with normal discharge. Consequently, same-day discharge may be considered a viable option, provided appropriate selection criteria are employed.

Dural Arteriovenous Fistulas (dAVFs) of the anterior cranial fossa (ACF) are uncommon but carry a high risk of hemorrhage and pose substantial treatment challenges. Recent advancements in endovascular treatment (EVT), including the introduction of novel liquid embolic agents, have markedly bolstered EVT's role in managing ACF-dAVFs, with notable series published in the last five years. We aimed to assess the feasibility, safety, and efficacy of EVT for ACF-dAVFs. We searched Medline, Scopus, Web of Science, and Cochrane Library databases following PRISMA guidelines. Eligible studies included those with ≥ 5 patients undergoing embolization of ACF-dAVFs, detailing both angiographic and clinical outcomes. We used single proportion analysis with 95% confidence intervals under a random-effects model, I2 to assess heterogeneity, and Baujat and sensitivity analysis to address high heterogeneity. Publication bias was assessed by funnel-plot analysis and Egger's test. Outcomes included complete occlusion following embolization, unsuccessful endovascular embolization attempts, incomplete occlusion following embolization, symptom resolution or clinical improvement following embolization, recurrence; procedure-related complications, morbidity, and mortality. Additionally, a subanalysis for studies exclusively utilizing Onyx™ embolic system was done. Eighteen studies comprising 231 ACF-dAVF were included. Unsuccessful endovascular embolization attempts rate was 2%. Complete occlusion rate was 85%, with 4% of complications. Incomplete occlusion rate was 10%. Successfully embolized patients experienced either symptom resolution or clinical improvement in 94% of cases. Morbidity and mortality rates were 1% and 0%, respectively. Onyx subanalyses showed an overall rate of 0% for unsuccessful attempts, 95% for complete occlusion, and 5% for incomplete occlusion. Symptom resolution or clinical improvement was 98% and recurrence rate was 0%. EVT for ACF-dAVF is highly feasible, effective, and safe, with a low rate of complications, morbidity, and mortality. The subanalyses focusing on Onyx embolizations revealed superior efficacy and safety outcomes compared to the findings of the primary analyses involving all included studies.

BACKGROUND: Craniosynostosis, a developmental craniofacial anomaly, can impair brain development and cause abnormal skull shape due to premature closure of one or more cranial sutures. Traditional surgical treatments have evolved from open operations to minimally invasive endoscopic techniques. This systematic review and meta-analysis aim to evaluate the effectiveness and safety of the endoscopic approach in craniosynostosis correction. METHODS: Adhering to Cochrane Group standards and the PRISMA framework, this review utilized databases like PubMed, Embase, and Web of Science, focusing on clinical and surgical outcomes of endoscopic craniosynostosis operations up to December 2023. Inclusion criteria emphasized studies with at least five patients undergoing endoscopic procedures, while exclusion criteria involved non-English papers, incomplete texts, and overlapping data. Statistical analysis used R software with various packages, and methodological bias was assessed using the ROBINS-I framework. RESULTS: The review included 30 studies (4 prospective, 26 retrospective) with 2561 patients. The median age at operation was 3.20 months. Findings showed a mean operative time of 68.06â¯min, median hospital stay of 1.28 days, and mean blood loss of 29.89â¯ml. Blood transfusion was required in 9.97% of cases. Helmet therapy post-operation was common, with a median duration of 9 months. The rate of postoperative complications was 1.86%, and the reoperation rate was 3.07%. No procedure-related mortality was observed. The study noted substantial variations in the handling of craniosynostosis and a lack of consensus on the optimal timing and surgical approach. CONCLUSION: Endoscopic techniques for craniosynostosis repair demonstrate safety and effectiveness, characterized by low complication risks and favorable surgical outcomes. However, due to the limitations of observational studies and inherent heterogeneity, further comprehensive and controlled trials are needed to validate these findings and understand the long-term outcomes of the endoscopic approach.

BACKGROUND: Intracranial pressure (ICP) monitoring plays a key role in patients with traumatic brain injury (TBI), however, cerebral hypoxia can occur without intracranial hypertension. Aiming to improve neuroprotection in these patients, a possible alternative is the association of Brain Tissue Oxygen Pressure (PbtO2) monitoring, used to detect PbtO2 tension. METHOD: We systematically searched PubMed, Embase and Cochrane Central for RCTs comparing combined PbtO2 + ICP monitoring with ICP monitoring alone in patients with severe or moderate TBI. The outcomes analyzed were mortality at 6 months, favorable outcome (GOS ≥ 4 or GOSE ≥ 5) at 6 months, pulmonary events, cardiovascular events and sepsis rate. RESULTS: We included 4 RCTs in the analysis, totaling 505 patients. Combined PbtO2 + ICP monitoring was used in 241 (47.72%) patients. There was no significant difference between the groups in relation to favorable outcome at 6 months (RR 1.17; 95% CI 0.95-1.43; p = 0.134; I2 = 0%), mortality at 6 months (RR 0.82; 95% CI 0.57-1.18; p = 0.281; I2 = 34%), cardiovascular events (RR 1.75; 95% CI 0.86-3.52; p = 0.120; I2 = 0%) or sepsis (RR 0.75; 95% CI 0.25-2.22; p = 0.604; I2 = 0%). The risk of pulmonary events was significantly higher in the group with combined PbtO2 + ICP monitoring (RR 1.44; 95% CI 1.11-1.87; p = 0.006; I2 = 0%). CONCLUSIONS: Our findings suggest that combined PbtO2 + ICP monitoring does not change outcomes such as mortality, functional recovery, cardiovascular events or sepsis. Furthermore, we found a higher risk of pulmonary events in patients undergoing combined monitoring.

Brain Arteriovenous Malformations (bAVMs) are rare but high-risk developmental anomalies of the vascular system. Microsurgery through craniotomy is believed to be the mainstay standard treatment for many grades of bAVMs. However, a significant challenge emerges in the existing body of clinical studies on open surgery for bAVMs: the lack of reproducibility and comparability. This study aims to assess the quality of studies reporting clinical and surgical outcomes for bAVMs treated by open surgery and develop a reporting guideline checklist focusing on essential elements to ensure comparability and reproducibility. This is a systematic literature review that followed the PRISMA guidelines with the search in Medline, Embase, and Web of Science databases, for studies published between January 1, 2018, and December 1, 2023. Included studies were scrutinized focusing on seven domains: (1) Assessment of How Studies Reported on the Baseline Characteristics of the Patient Sample; (2) Assessment and reporting on bAVMs grading, anatomical characteristics, and radiological aspects; (3) Angioarchitecture Assessment and Reporting; (4) Reporting on Pivotal Concepts Definitions; (5) Reporting on Neurosurgeon(s) and Staff Characteristics; (6) Reporting on Surgical Details; (7) Assessing and Reporting Clinical and Surgical Outcomes and AEs. A total of 47 studies comprising 5,884 patients were included. The scrutiny of the studies identified that the current literature in bAVM open surgery is deficient in many aspects, ranging from fundamental pieces of information of methodology to baseline characteristics of included patients and data reporting. Included studies demonstrated a lack of reproducibility that hinders building cumulative evidence. A bAVM Open Surgery Reporting Guideline with 65 items distributed across eight domains was developed and is proposed in this study aiming to address these shortcomings. This systematic review identified that the available literature regarding microsurgery for bAVM treatment, particularly in studies reporting clinical and surgical outcomes, lacks rigorous scientific methodology and quality in reporting. The proposed bAVM Open Surgery Reporting Guideline covers all essential aspects and is a potential solution to address these shortcomings and increase transparency, comparability, and reproducibility in this scenario. This proposal aims to advance the level of evidence and enhance knowledge regarding the Open Surgery treatment for bAVMs.

INTRODUCTION: Permanent liquor diversion is associated with a high risk of failure and often requires re-intervention. The ventriculo-gallbladder shunt (VGS) has been recognized as a last-resort alternative for treating hydrocephalus when the peritoneum or other distal sites are no longer suitable for receiving shunts. This article aims to report a case from a neurosurgery referral service in Brazil and review the literature on this issue. METHODS: A systematic literature review was conducted in accordance with the PRISMA statement. The PubMed, Embase, and Web of Science databases were searched for data screening and extraction. The reported case was conducted with ethical approval from the neurosurgical hospital's ethics committee. RESULTS: G.B.S, male, 43 years old, no comorbidities, who has been dealing with a 12-year history of hydrocephalus, with post-surgical chronic fungal meningitis. Two years ago, he underwent a ventriculoatrial shunt (VAS) placement due to multiple ventriculoperitoneal shunt (VPS) failures. Endocarditis was suspected, and the VAS was removed. As an alternative, VGS was implanted 6 months ago, and since then, there has been no need for a new system review. The gallbladder has an absorptive capacity of 1500 cc of liquid daily, which is more than the normal daily production of cerebrospinal fluid (CSF). Therefore, it is a good alternative when the ventriculoperitoneal shunt is not feasible due to postsurgical peritoneal adhesions or when there are contraindications for ventriculoatrial shunts. CONCLUSION: VGS is an alternative for patients who cannot undergo the most common surgical interventions, such as VPS.
