RESUMO
Odontoid fractures in the elderly typically require surgical intervention due to poor adaptability to conservative treatment. Anterior screw fixation, despite its high fusion rates under specific conditions, may lead to complications such as screw extrusion, as demonstrated in the case discussed, necessitating subsequent posterior cervical fusion. This study aimed to describe early extrusion of an anterior odontoid screw and the importance of caution and thorough postoperative assessment in elderly patients undergoing anterior screw fixation for odontoid fracture. A 73-year-old female patient with a history of ground-level fall and subsequent cervical pain was diagnosed with an odontoid type II fracture and underwent odontoid screw placement in June 2023. However, in August, follow-up imaging revealed screw displacement and a fracture of the posterior arch of the C1 vertebral, which was initially overlooked. After seeking a second opinion, a new surgical approach was decided, involving removal and replacement of the odontoid screw, posterior and posterolateral C1-C2 spinal instrumentation, arthrodesis, and fusion with the use of morselized allograft. The patient was discharged on postoperative day 3 with mild cervical pain, wearing a soft collar, and neurologically intact. Given the current literature, odontoid screw extrusion rates are still small but can come with enormous potential complications. Also, the present case is a reminder to always double-check preoperative imaging and recognize early failure/malpositioning of hardware.
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: Cerebral Venous Sinus Thrombosis (CVST) is a rare but potentially life-threatening condition, often associated with specific risk factors. The primary treatment for CVST is anticoagulation, but some cases progress to Refractory CVST (rCVST), requiring endovascular treatment. A combination of stent retriever and catheter aspiration is emerging as a promising technique to enhance treatment effectiveness. We conducted a systematic review and meta-analysis to assess the safety and efficacy of this approach, aiming to improve recanalization success and neurological outcomes while reducing complications in rCVST patients. METHODS: A search following PRISMA guidelines was conducted across Pubmed, Embase, Web of Science, and Cochrane databases to identify studies on the use of stent retrievers and catheter aspiration for rCVST. Pooled analysis with 95 % confidence intervals was used to assess the effects. Heterogeneity was evaluated using I2 statistics and a random-effects model was used. Complete recanalization. good clinical outcomes (mRS ≤ 2), hemorrhagic, neurological, ischemic, and total complications, poor clinical outcomes (mRS > 2), and mortality were assessed. RESULTS: A meta-analysis of five retrospective studies involving 55 patients examined outcomes in CVST. The median mean age was 40 years. Complete recanalization rate: 36 % (95 % CI: 9 % to 62 %, I2 = 90 %). Good clinical outcomes: 72 % (95 % CI: 50 % to 94 %, I2 = 76 %). Hemorrhagic complications: 2 % (95 % CI: 0 % to 8 %, I2 = 15 %). Ischemic complications: 0 % (95 % CI: 0 % to 6 %, I2 = 0 %). Neurological complications: 7 % (95 % CI: 0 % to 14 %, I2 = 0 %). Poor clinical outcomes: 26 % (95 % CI: 6 % to 46 %, I2 = 70 %). Total complications: 6 % (95 % CI: 0 % to 15 %, I2 = 10 %). Mortality rate: 5 % (95 % CI: 0 % to 13 %, I2 = 19 %). CONCLUSION: This systematic review and meta-analysis scrutinized the efficacy of combining Stent Retriever and Catheter Aspiration for rCVST. Findings highlighted varied outcomes, including recanalization rates, complications, and mortality. The dichotomy between good and poor outcomes underscores the necessity for personalized therapeutic decisions. While offering a comprehensive overview, the study emphasizes literature heterogeneity, suggesting a need for more rigorous and standardized research to optimize therapeutic strategies in clinical practice.

INTRODUCTION: Due to their delicate and deep-seated location, tumors in the pineal region of the brain pose exceptional challenges in neurosurgical management. Highly precise procedures have become crucial to address these complexities, such as the simultaneous performance of biopsy and endoscopic third ventriculostomy (ETV). Our aim was to assess the feasibility, safety, and efficacy of simultaneous biopsy and ETV for treating patients with pineal region tumors. METHODS: Medline, Embase, and Web of Science were searched for English studies from January 2000 to February 2024, following Cochrane and PRISMA guidelines. Eligible studies encompassed a minimum of four patients and examined at least one of the following outcomes: good clinical outcomes and the necessity of shunt placement. Single proportion analysis with 95% confidence intervals was conducted under a random-effects model, employing the I2 statistic to assess heterogeneity. Additionally, publication bias was evaluated using the ROBINS-I tool. RESULTS: After a meticulous selection process, eighteen studies involving 390 patients were included in the analysis. Overall, good clinical outcomes were observed in 131 out of 147 patients, representing a rate of 92 % (95 % CI: 84 % to 100 %, I2 = 62 %) through random effects analysis. Subgroup analysis showed that children exhibited a notably high rate of good clinical outcomes, reaching 100 % (95 % CI: 96 % to 100 %, I2 = 0 %). Regarding the need for shunt placement, out of the 356 patients assessed, only 39 required shunt placement, yielding a rate of 8 % (95 % CI: 4 % to 12 %, I2 = 63 %). Further sub-analyses indicated shunt requirement rates of 12 % for children and 3 % for adults. Specifically focusing on adults, data from 46 patients who underwent biopsy revealed a success rate of 84 % (95 % CI: 62 % to 100 %, I2 = 81 %). Remarkably, no major complications were reported among adults, resulting in a rate of 0 % (95 % CI: 0 % to 6 %, I2 = 0 %). Additionally, low rates of mortality related to the procedure were observed in adults, with two deaths recorded among the 46 patients analyzed, resulting in a mortality rate of 1 % (95 % CI: 0 % to 7 %, I2 = 0 %). CONCLUSION: In conclusion, our study aimed to assess the feasibility, safety, and efficacy of performing simultaneous biopsy and ETV for patients with pineal region tumors. We meticulously examined clinical aspects and patient outcomes, including good clinical outcomes, the requirement for shunt placement after ETV, biopsy success rates, mortality, and complications.
