Radiological and Clinical Significance of Cervical Dynamic Magnetic Resonance Imaging for Cervical Spondylotic Myelopathy.

Objective: The study compared the morphometric changes of the cervical spinal cord using dynamic magnetic resonance imaging (MRI) in patients with cervical spondylotic myelopathy (CSM) and assessed the correlation with kinematic changes, cord cross-sectional area (CSA), and high signal intensity (SI) on T2-weighted imaging (T2WI).

Methods: Patients with CSM were evaluated through dynamic MRI for sagittal and axial CSA changes of the cervical cord, cerebrospinal fluid (CSF) reserve ratio, degree of cord impingement, cord compression rate, range of motion (ROM), and severity of SI on T2WI. The degree of cord impingement was evaluated using the Muhle grading system.

Is a small coil more effective as a finishing coil for the embolization of intracranial aneurysms? Outcomes using GALAXY G3™ MINI micro-coils as finishing coils in a single center.

Objective: The purpose of this study was to compare the outcomes of coil embolization using a 0.009 inches primary outer diameter coil as finishing coil (FC) to that of 0.01 inches.

Incidental Microaneurysms During Microvascular Surgery: Incidence, Treatment, and Significance.

Background: Although new imaging tools have been developed for the detection of smaller aneurysms, angiographically negative microaneurysms are still encountered during cerebral microsurgery. Currently, only limited information regarding incidence and efficacy of treatment of these microaneurysms is available.

Methods: We investigated the incidence and treatment of incidental microaneurysms (IMAs) in the last 5 years.

Increased Glucose Variability During Long-Term Therapeutic Hypothermia as a Predictor of Poor Neurological Outcomes and Mortality: A Retrospective Study.

Therapeutic hypothermia (TH) is considered as a treatment option in patients with stroke and brain injury for controlling intracranial pressure. A relatively longer duration of TH is required in such patients than in cardiac arrest patients. We aimed to investigate blood glucose parameters during TH that predict unfavorable neurological outcomes and mortality in patients admitted to the neurological or neurosurgical intensive care unit (ICU).

Long-term outcomes of treatment for unruptured intracranial aneurysms in South Korea: clipping versus coiling.

Background: The long-term outcomes of endovascular coiling and surgical clipping for the treatment of unruptured intracranial aneurysms are unclear.

Methods: We performed a nationwide retrospective cohort study using claims data from the Korean Health Insurance Review and Assessment Service on patients undergoing surgical clipping or endovascular coiling from 2008 to 2014. Inverse probability treatment weighting for average treatment effect on the treated and the multiple imputation method were used to balance covariates and handle missing values.

Radiologic Measurement of Brain Swelling in Patients with Large Hemispheric Infarctions During Targeted Temperature Management.

Brain herniation is most often the result of severe brain swelling and can rapidly lead to death or brain death. We retrospectively identified radiologic indicators to evaluate the effects of targeted temperature management (TTM) on the extent of cerebral edema and determine the cutoff values that best predict TTM outcomes in patients with large hemispheric infarction. We retrospectively reviewed brain computed tomography (CT) scans of 21 patients with large hemispheric infarctions, who were treated with TTM.

Effect of statin on progression of symptomatic basilar artery stenosis and subsequent ischemic stroke.

Background And Objective: Symptomatic basilar artery stenosis (BAS) is associated with high risk of ischemic stroke recurrence. We aimed to investigate whether statin therapy might prevent the progression of symptomatic BAS and stroke recurrence.

Methods: We retrospectively analyzed the data of patients with acute ischemia with symptomatic BAS, which was assessed using magnetic resonance angiogram (MRA) imaging on admission day, and 1 year later (or the day of the clinical event).

A Dedicated Neurological Intensive Care Unit Offers Improved Outcomes for Patients With Brain and Spine Injuries.

Background: Admission to an intensive care unit (ICU) specialized for brain and spine injury patients is associated with improved outcome. We investigated the effects of the first dedicated, combined neurological and neurosurgical ICU (NeuroICU) in Korea on patient outcomes.

Methods: The first dedicated NeuroICU in Korea was established in March 2013.

Efficacy and Safety of Fractionated Stereotactic Radiosurgery for Large Brain Metastases.

Objective: To investigate the efficacy and safety of fractionated stereotactic radiosurgery for large brain metastases (BMs).

Methods: Between June 2011 and December 2013, a total of 38 large BMs >3.0 cm in 37 patients were treated with fractionated Cyberknife radiosurgery.

Thoracic Extradural Cavernous Hemangioma Mimicking a Dumbbell-Shaped Tumor.

Dumbbell-shaped spinal extradural cavernous hemangioma is rare. The differential diagnosis of dumbbell-shaped spinal tumors based on magnetic resonance imaging includes schwannoma and lymphoma. Here, we report a dumbbell-shaped spinal extradural cavernous hemangioma with intrathoracic growth on T2-3 in a 64-year-old man complaining of right side infrascapular area back pain with no neurologic deficit.
