Neurosurgical papers with practical application

OBJECTIVE: Endovascular intracranial aneurysm (IA) management has significantly evolved over the last 2 decades. Despite these advancements, the aneurysm recanalization rate after coil embolization remains a concern. Statins have been found to affect vascular repair and remodeling; therefore, the authors hypothesized that patients receiving statin therapy at the time of coil embolization would have lower aneurysm recurrence and retreatment rates compared with patients not receiving statin therapy...

OBJECTIVE: Intraventricular hemorrhage (IVH) is a serious condition with high mortality rates and poor functional outcome in survivors. Treatment includes external ventricular drains (EVDs), which are associated with several complications. This study reports the clinical outcome and complication rate in patients with primary IVH (pIVH) and secondary IVH treated with EVDs. METHODS: The authors conducted a retrospective observational study using the Danish National Patient Registry...

BACKGROUND AND OBJECTIVES: Conventional surgical modalities, including twist drill craniotomy, burr hole evacuation, and craniotomy, are the standard surgical interventions for chronic subdural hematomas (cSDH). More recently, treatment of cSDH with middle meningeal artery embolization (MMAE) is being explored. The comparative effectiveness of MMAE versus conventional surgical modalities remains controversial. The objective of this study is to analyze various postoperative outcomes in an umbrella review of existing meta-analysis comparing MMAE and conventional management in patients with cSDH...

OBJECTIVES: The goal of this study was to characterize the largest known cohort of patients presenting with different tumor pathologies in the third ventricle region to better understand outcomes of surgical management. METHODS: All patients undergoing surgical intervention on tumors in or encroaching upon the third ventricle at Loyola University Medical Center between the years 1986-2021 were reviewed. Information recorded included presenting symptoms, pre- and post-operative interventions, tumor pathology, operative technique, extent of resection (EOR), and approach of operation...

OBJECTIVE: Sphenoid wing meningiomas (SWMs) often cause occlusion or stenosis of the superficial middle cerebral vein (SMCV) by tumor compression. This study aimed to analyze the correlation between SMCV compression and peritumoral brain edema (PTBE) in SWM patients and to clarify the importance of surgical preservation of the SMCV in SWM surgery. METHODS: This retrospective study included 31 patients who underwent surgery for SWM at our institution from April 2011 to March 2022...

OBJECTIVE: Symptomatic intracerebral hemorrhage (sICH) after stroke is a devastating neurological complication. Current guidelines support a "possible benefit" of decompressive craniectomy (DC) for large supratentorial sICH with significant mass effect. METHODS: The authors conducted a retrospective study of 8 comprehensive stroke centers. They included all patients who sustained an sICH after acute ischemic stroke (AIS), as defined by the Safe Implementation of Thrombolysis in Stroke-Monitoring Study (SITS-MOST), from January 2016 to December 2020...

BACKGROUND AND OBJECTIVES: Decompressive craniectomy (DC) is a commonly performed procedure to alleviate high intracranial pressure. To enhance patient quality of life and minimize complications after DC in patients awaiting cranioplasty (CP), multidisciplinary teams have designed and implemented external protective prototypes, including 3-dimensional printing and plaster models, whenever feasible. The aim of this scoping review was to assess the evidence available on innovative external cranial devices that protect the craniectomy site for patients who have undergone DC while awaiting CP in high-income countries and low- and middle-income countries...

OBJECTIVE: The modified Brain Injury Guidelines (mBIG) were developed to improve care of patients with traumatic brain injury (TBI). This study aimed to assess if utilization of mBIG by neurosurgeons would improve TBI patient throughput at a Level I trauma center, particularly for patients meeting mBIG 1 criteria. METHODS: This was a retrospective observational study at a Level I trauma center. The mBIG were adopted in November 2021. Outcome and safety data for patients ≥18 years old meeting mBIG 1 criteria treated 18 months before (pre-mBIG cohort) or after (post-mBIG cohort) implementation were compared...

OBJECTIVE: Hydrocephalus is a lifelong condition punctuated in most cases by unpredictable hospital admissions for surgical maintenance. It occupies more of the attention of the pediatric neurosurgeon than any other condition. Benchmarks for the measurement of outcomes are of interest to patients, their families, and the healthcare system. Compared to other metrics, 30-day outcomes require modest resources to collect, are conceptually transparent, and are responsive to process improvement...

BACKGROUND: Ventriculoperitoneal (VP) shunts are commonly used for managing hydrocephalus, with mechanical dysfunction being the most common cause of complications that require revision. A VP shunt placed using a real-time three-dimensional (3D) robotic C-arm navigation system may have better outcomes and fewer complications. METHODS: In this technical note, we introduced the workflow of the use of the real-time 3D robotic C-arm navigation system for ventriculoperitoneal shunting...

The authors report their experience with twenty-one consecutive patients who presented with symptoms and imaging characteristics of a herniated lumbar disc; of whom, at the time of surgery had a vascular loop instead. The procedure was performed on 14 women and seven men with a mean age of 39 years. Clinical complaints included lumbar aching with one limb overt radiculopathy in all patients; with additional sphincter dysfunction in two cases. Symptoms had developed within a mean period of three months...

BACKGROUND: The predictive role of multiple risk factors for intracranial atypical and anaplastic meningioma recurrence is convoluted. This meta-analysis assessed the predictive value of selected factors for recurrence in these Meningiomas. METHODS: Studies encompassing risk factor data including gross total resection (GTR), subtotal resection (STR), post-op radiotherapy, Ki-67 % index >3 %, and location were searched for in PubMed, Embase, and Web of Science, and thereafter analyzed using robust Bayesian meta-analysis...

The recurrence of chronic subdural hematoma (CSDH) after surgical treatment is a severe problem with no effective prevention method. This retrospective study aimed to investigate factors associated with CSDH recurrence after burr hole surgery and hematoma changes on computed tomography before surgery to examine prevention methods for recurrence. A total of 166 hematomas were enrolled in this study, with 139 patients undergoing burr hole surgery for CSDH. Among these patients, 17 (12 %) had recurrence...

OBJECTIVE: The aim of this study was to evaluate the morbidity associated with microsurgical treatment in patients with a recurrent aneurysm to improve their surgical management. METHODS: From 2012 to 2022, among the 3128 patients with ruptured or unruptured intracranial aneurysms managed at the authors' institution, 954 patients were treated by a microsurgical procedure. Of these 3128 patients, 60 consecutive patients (6.3%) who had a recurrent microsurgically treated aneurysm after previous endovascular treatment were included in this study...

INTRODUCTION: Cerebellar mutism syndrome (CMS) is a serious complication of posterior fossa surgeries affecting mainly pediatric age group. The pathophysiology is still not fully understood. It adversely affects the recovery of patients. There is no definitive and standardized management for CMS. However pharmacological therapy has been used in reported cases with variable effectiveness. We aim through this review to summarize the available evidence on pharmacological agents used to treat CMS...

The November 2013 online publication of ARUBA, the first multi-institutional randomized controlled trial for unruptured brain arteriovenous malformations (AVMs), has sparked over 100 publications in protracted debates METHODS: This study sought to examine inpatient management patterns of brain AVMs from 2009 to 2016 and observe if changes in U.S. inpatient management were attributable to the ARUBA publication using interrupted time series of brain AVM studies from the National Inpatient Sample data 2009-2016...

INTRODUCTION: Severe traumatic brain injury (TBI) presentation and late clinical outcomes are usually evaluated by the Glasgow Outcome Scale-Extended (GOS-E), which lacks strong prognostic predictability. Several blood biomarkers have been linked to TBI, such as Tau, GFAP, UCH-L1, S-100B, and NSE. Clinical values of TBI biomarkers have yet to be evaluated in a focused multi-study meta-analysis. We reviewed relevant articles evaluating potential relationships between TBI biomarkers and both early and 6-month outcomes...

OBJECTIVE: Chronic subdural hematoma (CSDH) is a prevalent neurosurgical condition, particularly among the elderly. Various treatment options exist, but recurrence rates remain high. This systematic review and meta-analysis aims to assess the efficacy and safety of tranexamic acid (TXA) in the management of CSDH. METHODS: The authors conducted a comprehensive literature search adhering to the 2020 PRISMA guidelines, involving three primary databases (Scopus, PubMed, and Web of Science) that were searched for articles compiled from inception until October 20, 2023...

OBJECTIVE: The aim of this study was to compare the outcomes of early (≤ 90 days) and delayed (> 90 days) cranioplasty following decompressive craniectomy (DC) in patients with traumatic brain injury (TBI).
