A Comprehensive Analysis of Stent during Stent Assisted Coil Embolization for Cerebral Aneurysms: A 17-Year Institutional Study.

Aim: To compare the outcomes and complications of stent-assisted coil (SAC) embolization for the treatment of cerebral aneurysms according to stent type.

Material And Methods: Since January 2006, a total of 1293 patients have been added to our institutional aneurysm database. We excluded cases with subarachnoid hemorrhage, those not classified as Raymond Roy Class 1, and those in which flow diverters were used.

Comparative analysis of hypofractionated short-course versus standard radiation therapy in elderly patients with glioblastoma: analysis of nationwide database.

Purpose: Hypofractionated short-course radiation therapy (SCRT) is an alternative treatment option for elderly or frail patients with newly diagnosed glioblastoma (GBM) post-surgery. This study compares survival outcomes and treatment costs between patients receiving SCRT and those undergoing standard long-course radiation therapy (LCRT).

Methods: This retrospective study utilized health insurance claims and national cancer registry data from Korea to compare overall survival (OS) and treatment costs between patients receiving SCRT and LCRT across all ages and sub-group analysis within the subgroup of cases aged 65 and older from 2016 onwards, a period when intensity-modulated radiotherapy (IMRT) was widely adopted.

Assessing the Suitability of Artificial Intelligence-Based Chatbots as Counseling Agents for Patients with Brain Tumor: A Comprehensive Survey Analysis.

Objective: The internet, particularly social media, has become a popular resource for learning about health and investigating one's own health conditions. The development of artificial intelligence (AI) chatbots has been fueled by the increasing availability of digital health data and advances in natural language processing techniques. While these chatbots are more accessible than before, they sometimes fail to provide accurate information.

Preliminary Report of Fully Endoscopic Microvascular Decompression.

Objective: Microscopic microvascular decompression (MVD) has been considered to be a useful treatment modality for medically refractory hemifacial spasm (HFS) and trigeminal neuralgia. But, the advent of the endoscopic era has presented new possibilities to MVD surgery. While the microscope remains a valuable tool, the endoscope offers several advantages with comparable clinical outcomes.

Strategy of stretched Coils: Insights from a single center experience.

Objective: A stretched coil, characterized by excessive elongation within the parent artery during a coil embolization procedure, poses a significant risk of forming a thrombus. This study reports on cases of stretched coils spanning 16 years and discusses effective assessment methods and treatment strategies.

Method: Retrospective analysis of the institutional database comprising 14 cases where stretched coils were observed during coil embolization procedures was conducted, starting from January 2007.

Optimization of a Protocol for Isolating Cell-free DNA From Cerebrospinal Fluid.

A standardized protocol for the isolation of cell-free DNA (cfDNA) from cerebrospinal fluid (CSF) is lacking. Therefore, we established a cfDNA isolation protocol optimized for clinical CSF specimens, integrating acceptable modifications and using artificial CSF generated from remnant CSF spiked with reference cell-free tumor DNA (ctDNA). We compared the isolation yields of diagnostic (IVD)-certified column-based (CB) and magnetic bead-based (MB) isolation.

Navigation guided small craniectomy and direct cannulation of pure isolated sigmoid sinus for treatment of dural arteriovenous fistula.

Dural arteriovenous fistula (DAVF) is a rare condition affecting approximately 1.5% of 1,000,000 individuals annually. It frequently occurs in the transsigmoid and cavernous sinuses.

The Korean Society for Neuro-Oncology (KSNO) Guideline for the Management of Brain Tumor Patients During the Crisis Period: A Consensus Survey About Specific Clinical Scenarios (Version 2023.1).

Background: During the coronavirus disease 2019 (COVID-19) pandemic, there was a shortage of medical resources and the need for proper treatment guidelines for brain tumor patients became more pressing. Thus, the Korean Society for Neuro-Oncology (KSNO), a multidisciplinary academic society, has undertaken efforts to develop a guideline that is tailored to the domestic situation and that can be used in similar crisis situations in the future. As part II of the guideline, this consensus survey is to suggest management options in specific clinical scenarios during the crisis period.

Long-term outcomes of carotid artery stenting in patients with carotid artery stenosis: A single-center 14-year retrospective analysis.

Objective: Carotid artery stenting (CAS) is currently widely used for the treatment of carotid artery stenosis. The objective of this study was to analyze the outcomes of CAS performed in a single institution.

Methods: We retrospectively analyzed 313 CAS cases from January 2007 to December 2020, including 206 (66%) symptomatic and 107 (34%) asymptomatic cases.

Multiple Cerebral Hemorrhages Caused by Paradoxical Reperfusion Injury After Cranioplasty.

Cranioplasty-related reperfusion injury has rarely been reported. Although there are several hypotheses, particularly regarding the mechanisms of the event, clear evidence is lacking. Here, we report the case of an 84-year-old man with traumatic intracranial hemorrhage and subdural hematoma who underwent decompressive craniectomy and hematoma evacuation in the right hemisphere.

Treatment of pituitary adenoma with spontaneous cerebrospinal rhinorrhea using nasoseptal flap, two case reports.

Background: Postoperative cerebrospinal fluid (CSF) leakages are well documented, but pituitary adenoma with spontaneous CSF rhinorrhea as the initial symptoms are extremely rare. The objective of this study is to report two rare cases of pituitary adenoma with spontaneous CSF rhinorrhea successfully operated by endoscopic transsphenoidal approach with vascularized nasoseptal flap (NSF).

Case Description: A 70-year-old woman presented with a 6-month history of watery rhinorrhea and posterior nasal drip that worsened when her head leaning forward.

Supraorbital Endoscopic Evacuation for Traumatic Intracerebral Hematomas in the Frontal Lobe.

Objective: Traumatic intracranial hematomas have been rarely evacuated by endoscopic surgery. The frontal lobe is the usual location for the traumatic intracerebral hematoma (TICH). Endoscopic evacuation for the frontal TICHs via an eyebrow incision is to be presented as minimally invasive surgery.

A Radiological Assessment of Chronic Subdural Hematomas.

Chronic subdural hematoma (CSDH), which generally occurs in elderly patients, is a frequently diagnosed condition in neurosurgical departments. Computed tomography (CT) and magnetic resonance imaging (MRI) are the most preferred diagnostic modalities for CSDH assessment. With early diagnosis and adequate management, CSDH may show favorable prognosis in majority of the patients; however, recurrence after surgery can occur in a significant number of patients.

Short- and long-term mortality after intravenous thrombolysis for acute ischemic stroke: A propensity score-matched cohort with 5-year follow-up.

It remains unknown whether intravenous thrombolysis (IVT), thrombectomy, or poststroke antithrombotic medication lower short- and long-term mortality in acute ischemic stroke (AIS). This study aimed to investigate the efficacy of IVT in AIS using propensity score matching, to determine whether IVT could reduce short- and long-term mortality, and to identify risk factors influencing short- and long-term mortality in AIS.During 2013 to 2014, the nationwide Korea Acute Stroke Assessment registry enrolled 14,394 patients with first-ever recorded ischemic stroke.
