BACKGROUND: The exact reason of non-aneurysmal SAH is an enigma. OBJECTIVE: To identify if type III deep cerebral venous drainage is exclusively prevalent in patients with non-aneurysmal SAH and to enumerate the predictors of poorer outcome in these patients. PATIENTS: All patients of age >18 years, presented at our centre with spontaneous SAH on NCCT head and were divided into two groups, aneurysmal and non-aneurysmal SAH after 4-vessel DSA...

OBJECTIVE: To evaluate the relationships between Doximity rankings (Doximity, Inc.) of residency programs and two new ranking systems based on publication rates and academic pursuits. METHODS: We collected data on 550 neurosurgery graduates over 3 years. We analyzed the median number of published manuscripts per resident and the percentage of residents pursuing academic careers and compared them across the Doximity Research Productivity and Reputation Rankings. We used logistic regression to evaluate the relationships among the rankings, publication rates, and academic pursuits...

BACKGROUND: We searched to quantify the influence of sagittal vertical axis (SVA) on the improvement of spatiotemporal gait parameters using a gait motion analysis (GMA) before and after decompression surgery in patients suffering from lumbar stenosis (LSS). METHODS: Thirty-nine patients with severe LSS planned for lumbar decompression underwent a full body biplanar radiographs (EOS®) to quantify the SVA, and have benefited from a three-dimensional GMA one month before surgery (M0) and 6 month (M6) after surgery...

BACKGROUND: Learning curve, training, and cost impede widespread implementation of new technology. Neurosurgical robotic technology introduces challenges to visuospatial reasoning and requires the acquisition of new fine motor skills. Studies detailing operative workflow, learning curve, and patient outcomes are needed to describe the utility and cost-efficacy of new robotic technology. OBJECTIVES: This study describes our institutional experience incorporating the Medtronic Stealth Autoguide for stereoelectroencephalography (sEEG) in a pediatric population, focusing on learning curve, quantified via accuracy and efficiency over time...

OBJECTIVES: The goal of this study is to implement machine learning (ML) algorithms to predict mortality, non-home discharges, prolonged length of stay (LOS), prolonged length of intensive care unit stay (ICU-LOS), and major complications in patients diagnosed with thoracolumbar spinal cord injury (tlSCI), while creating a publicly accessible online tool. METHODS: The American College of Surgeons Trauma Quality Program database was utilized to identify patients with tlSCI...

OBJECTIVE: We aim to assess the incidence and impact of in-hospital medical complications (MCs) on clinical outcomes in acute ischemic stroke (AIS) patients after endovascular therapy (EVT). METHODS: AIS patients who underwent EVT were consecutively recruited from January 2019 to July 2022. The primary outcome was a poor 3-month functional outcome, defined as a modified Rankin Scale score (mRS) of 3-6. The safety variables were symptomatic intracerebral hemorrhage (sICH) and mortality at seven and 30 days...

OBJECTIVE: The primary aim of this research was to harness the capabilities of deep learning to enhance neurosurgical procedures, focusing on accurate tumor boundary delineation and classification. Through advanced diagnostic tools, we aimed to offer surgeons a more insightful perspective during surgeries, improving surgical outcomes and patient care. METHODS: The study deployed the Mask R-CNN architecture, leveraging its sophisticated features to process and analyze data from surgical microscope videos and preoperative MR images...

OBJECTIVE: Surgical traumatic acute subdural hematoma (aSDH) patients taking antithrombotic medications require careful hematologic management. We sought to compare outcomes between aSDH patients taking antithrombotic medications at admission who received antithrombotic reversal with aSDH patients not taking antithrombotics. METHODS: Retrospective review identified traumatic aSDH patients requiring surgical evacuation. Our cohort was divided based on antithrombotic use and whether pharmacologic reversal agents or platelet transfusions were administered...

OBJECTIVE: The differential diagnosis for postoperative back pain is broad, and conventional imaging modalities are not always conclusive. Therefore, we performed a systematic review of the literature and present case studies describing the use of single-photon emission CT (SPECT)/CT or positron emission tomography (PET)/CT in the diagnosis of back pain following spine surgery. METHODS: A systematic review was conducted according to PRISMA guidelines across 5databases...

BACKGROUND: Augmented reality (AR) is an emerging technology in neurosurgery with the potential to become a strategic tool in the delivery of care and education for trainees. Advances in the technology have demonstrated promising use for improving visualization and spatial awareness of critical neuroanatomical structures. In this report, we employ a novel AR registration system for the visualization and targeting of skull landmarks. METHODS: A markerless AR system was used to register 3D reconstructions of suture lines onto the head via a head mounted display...

BACKGROUND: Traumatic cervical spinal cord injury (tCSCI) is often a debilitating injury, making early prognosis important for medical and surgical planning. Currently, the best early predictors of prognosis are the physical examination, imaging studies, and patient demographics. Despite these factors, patient outcomes continue to vary significantly. The purpose of this study was to evaluate the prognostic value of somatosensory evoked potentials (SSEPs) with functional outcomes in tCSCI patients...

OBJECTIVE: To evaluate the neurosurgical and economical effectiveness of a newly launched intraoperative high field (3-Tesla) magnetic resonance MR imaging suite for pediatric tumor and epilepsy neurosurgery. METHODS: Altogether, 148 procedures for 124 pediatric patients (mean age 8.7 years, range 0 - 18 years) within a 2.5-year periode were undertaken in a two- room intraoperative MRI (iopMRI) suite. Surgeries were mainly performed for intractable epilepsy (n=81, 55%) or pediatric brain tumors (n=65, 44%) in supine (n=113, 76%) and prone (n=35, 24%) position...

OBJECTIVES: The role of surgery in spontaneous intracerebral hemorrhage (SICH) remains controversial. We aimed to use explainable machine learning (ML) combined with propensity-score matching to investigate the effects of surgery and identify SICH patient subgroups who may benefit from surgery in an interpretable fashion. MATERIALS AND METHODS: We conducted a retrospective cohort of 282 patients aged 21 and above with SICH. ML models were developed to separately predict for surgery and for surgical evacuation...

OBJECTIVE: To compare the clinical and radiological outcomes of endoscopic transforaminal lumbar interbody fusion (Endo-TLIF) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF). METHODS: This retrospective study included 110 patients with single-level lumbar degenerative disease who underwent Endo-TLIF or MIS-TLIF between January 2019 and December 2021. Patients were divided into Endo-TLIF (n = 55) and MIS-TLIF groups (n = 55). Perioperative, clinical, and radiological outcomes were assessed...

OBJECTIVE: To investigate whether retro-odontoid soft-tissue thickness (ROSTT) is associated with cervical degeneration, cervical spine mobility, and sagittal balance of cervical spine. METHODS: The data of 151 patients who presented at our hospital with cervical spondylosis were reviewed. The ROSTT was measured using T1-weighted sagittal cervical MRI fundings. The assessment of the degree of cervical intervertebral disc degeneration (IVDD) was conducted using sagittal T2-weighted imaging...
